Masahiro Yamada d503ac531a kbuild: rename LDFLAGS to KBUILD_LDFLAGS
Commit a0f97e06a4 ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.

Commit 222d394d30 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.

Commit 06c5040cdb ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.

For some reason, LDFLAGS was not renamed.

Using a well-known variable like LDFLAGS may result in accidental
override of the variable.

Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.

I did not touch Makefiles under tools/ since the tools build system
is a different world.

Masahiro Yamada 2288fd5180 ARM: 8779/1: add endianness option to LDFLAGS instead of LD
With the recent syntax extension, Kconfig is now able to evaluate the
compiler / toolchain capability.

However, accumulating flags to 'LD' is not compatible with the way
it works; 'LD' must be passed to Kconfig to call $(ld-option,...)
from Kconfig files.  If you tweak 'LD' in arch Makefile depending on
CONFIG_CPU_BIG_ENDIAN, this would end up with circular dependency
between Makefile and Kconfig.

 32- and 64-bit platforms. The branch also contains defconfig updates to
 turn on drivers and options as needed on the various platforms.
 
 The largest parts of the delta are from cleanups moving platform data
 and board file setup of TI platforms to ti-sysc bus drivers. There are
 also some sweeping changes of eeprom and nand setup on Davinci, i.MX
 and other platforms.
 
 Samsung is removing support for Exynos5440, which was an oddball SoC
 that hasn't been seen much use in designs.
 
 Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
 
 Linus Walleij is also removing support for ux500 (Sony Ericsson)
 U8540/9540 SoCs that never made it to significant mass production and
 products.

Luc Van Oostenryck 1f2f01b122 kbuild: add machine size to CHECKFLAGS
By default, sparse assumes a 64bit machine when compiled on x86-64
and 32bit when compiled on anything else.

This can of course create all sort of problems for the other archs, like
issuing false warnings ('shift too big (32) for type unsigned long'), or
worse, failing to emit legitimate warnings.

Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT,
to CHECKFLAGS in the main Makefile (and so for all archs).
Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

Nicolas Pitre 75fea300d7 ARM: 8723/2: always assume the "unified" syntax for assembly code
The GNU assembler has implemented the "unified syntax" parsing since
2005. This "unified" syntax is required when the kernel is built in
Thumb2 mode. However the "unified" syntax is a mixed bag of features,
including not requiring a `#' prefix with immediate operands. This leads
to situations where some code builds just fine in Thumb2 mode and fails
to build in ARM mode if that prefix is missing. This behavior
discrepancy makes build tests less valuable, forcing both ARM and Thumb2
builds for proper coverage.

Let's "fix" this issue by always using the "unified" syntax for both ARM
and Thumb2 mode. Given that the documented minimum binutils version that
properly builds the kernel is version 2.20 released in 2010, we can
assume that any toolchain capable of building the latest kernel is also
"unified syntax" capable.

Linus Torvalds 09bd7c75e5 Kbuild updates for v4.15
One of the most remarkable improvements in this cycle is, Kbuild is
 now able to cache the result of shell commands.  Some variables are
 expensive to compute, for example, $(call cc-option,...) invokes the
 compiler.  It is not efficient to redo this computation every time,
 even when we are not actually building anything.  Kbuild creates a
 hidden file ".cache.mk" that contains invoked shell commands and
 their results.  The speed-up should be noticeable.
 
 Summary:
 
 - Fix arch build issues (hexagon, sh)
 
 - Clean up various Makefiles and scripts
 
 - Fix wrong usage of {CFLAGS,LDFLAGS}_MODULE in arch Makefiles
 
 - Cache variables that are expensive to compute
 
 - Improve cc-ldopton and ld-option for Clang
 
 - Optimize output directory creation

Linus Torvalds 8c60969856 ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added
 drivers or features that people have started using. For the changed
 lines lines, we have mostly cleanups, the affected platforms are
 OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
 
 The largest single change is the introduction of the TI "sysc" bus
 driver, with the intention of cleaning up more legacy code.
 
 Two new SoC platforms get added this time:
 - Allwinner R40 is a modernized version of the A20 chip, now
   with a Quad-Core ARM Cortex-A7. According to the manufacturer,
   it is intended for "Smart Hardware"
 - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
   of chips meant for managed gigabit ethernet switches, based
   around a Cortex-A9 CPU.
 
 Finally, we gain SMP support for two platforms: Renesas R-Car E2
 and Amlogic Meson8/8b, which were previously added but only supported
 uniprocessor operation.

Luc Van Oostenryck ff0c6eecef ARM: 8716/1: pass endianness info to sparse
ARM depends on the macros '__ARMEL__' & '__ARMEB__' being defined
or not to correctly select or define endian-specific macros,
structures or pieces of code.

These macros are predefined by the compiler but sparse knows
nothing about them and thus may pre-process files differently
from what gcc would.

Fix this by passing '-D__ARMEL__' or '-D__ARMEB__' to sparse,
depending on the endianness of the kernel, like defined by GCC.

Note: In most case it won't change anything since most ARMs use
      little-endian (but an allyesconfig would use big-endian!).

Luc Van Oostenryck II 6042b8c7c0 ARM: 8701/1: fix sparse flags for build on 64bit machines
By default sparse uses the characteristics of the build
machine to infer things like the wordsize.
This is fine when doing native builds but for ARM it's,
I suspect, very rarely the case and if the build are done
on a 64bit machine we get a bunch of warnings like:
  'cast truncates bits from constant value (... becomes ...)'

Fix this by adding the -m32 flags for sparse.

Russell King 96a8fae0fe ARM: convert to generated system call tables
Convert ARM to use a similar mechanism to x86 to generate the unistd.h
system call numbers and the various kernel system call tables.  This
means that rather than having to edit three places (asm/unistd.h for
the total number of system calls, uapi/asm/unistd.h for the system call
numbers, and arch/arm/kernel/calls.S for the call table) we have only
one place to edit, making the process much more simple.

The scripts have knowledge of the table padding requirements, so there's
no need to worry about __NR_syscalls not fitting within the immediate
constant field of ALU instructions anymore.

We currently define OBJCOPYFLAGS in the top-level arm Makefile, and thus
these flags will be passed to all uses of objcopy, kernel-wide, for
which they are not explicitly overridden. The flags we set are intended
for converting a few ELF files into raw binaries, and thus the flags
chosen are problematic for some other uses which do not expect a raw
binary result, e.g. the upcoming lkdtm rodata test:

  http://www.openwall.com/lists/kernel-hardening/2016/06/08/2

In case of ARM_SINGLE_ARMV7M, we end up also exporting them,

Commit 3939f33450 ("ARM: 8418/1: add boot image dependencies to
not generate invalid images") fixed bad image generation for the
parallel building, but as its side effect, Kbuild now descends into
arch/arm/boot/ again and again, duplicating the log messages.
It looks clumsy, so let's display the same message only once.

This commit moves the log rules from arch/arm/boot/Makefile to
arch/arm/Makefile.  I did not delete them completely because *Image
are the final targets that users are interested in.

Without this commit, the log of incremental build is like follows:

$ make ARCH=arm UIMAGE_LOADADDR=0x80208000 uImage
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
  CHK     include/generated/bounds.h

These two targets were introduced by commit 13d5fadf45 ("[ARM]

for 'install' and 'zinstall'.

After that, commit 19514fc665 ('arm, kbuild: make "make install"
not depend on vmlinux') eventually made "(z)install" equivalent to
"(z)i".

It is true that 'i' and 'zi' might be still useful as shorthands
but the original intention had been already lost.

They do not even show up in "make ARCH=arm help", so I hope this
deletion does not have much impact.

As usual, a bunch of commits, mostly adding drivers and other options to

 There's an introduction of a pxa_defconfig, since PXA finally will allow
 building a shared kernel for all boards. With this, we can hopefully
 remove a bunch of individual defconfigs down the road but it requires
 a bit of real life testing and transition period.

versatile_defconfig has not been a reasonable default for a very long

based on an old ARM926 CPU core.

This changes the default to multi_v7_defconfig, which is much more
relevant to anyone doing a build test on ARM, as it covers a wide
range of platforms.

Ard Biesheuvel a077224fd3 ARM: 8429/1: disable GCC SRA optimization
While working on the 32-bit ARM port of UEFI, I noticed a strange
corruption in the kernel log. The following snprintf() statement
(in drivers/firmware/efi/efi.c:efi_md_typeattr_format())

	snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",

was producing the following output in the log:

	|    |   |   |   |    |WB|WT|WC|UC]
	|    |   |   |   |    |WB|WT|WC|UC]
	|    |   |   |   |    |WB|WT|WC|UC]
	|RUN|   |   |   |    |WB|WT|WC|UC]*
	|RUN|   |   |   |    |WB|WT|WC|UC]*
	|    |   |   |   |    |WB|WT|WC|UC]
	|RUN|   |   |   |    |WB|WT|WC|UC]*
	|    |   |   |   |    |WB|WT|WC|UC]
	|RUN|   |   |   |    |   |   |   |UC]
	|RUN|   |   |   |    |   |   |   |UC]

As it turns out, this is caused by incorrect code being emitted for
the string() function in lib/vsprintf.c. The following code

	if (!(spec.flags & LEFT)) {
		while (len < spec.field_width--) {
			if (buf < end)
				*buf = ' ';
			++buf;
		}
	}
	for (i = 0; i < len; ++i) {
		if (buf < end)
			*buf = *s;
		++buf; ++s;
	}
	while (len < spec.field_width--) {
		if (buf < end)
			*buf = ' ';
		++buf;
	}

when called with len == 0, triggers an issue in the GCC SRA optimization
pass (Scalar Replacement of Aggregates), which handles promotion of signed
struct members incorrectly. This is a known but as yet unresolved issue.
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
case, it is causing the second while loop to be executed erroneously a
single time, causing the additional space characters to be printed.

So disable the optimization by passing -fno-ipa-sra.

Masahiro Yamada 3939f33450 ARM: 8418/1: add boot image dependencies to not generate invalid images
U-Boot is often used to boot the kernel on ARM boards, but uImage
is not built by "make all", so we are often inclined to do
"make all uImage" to generate DTBs, modules and uImage in a single
command, but we should notice a pitfall behind it.  In fact,
"make all uImage" could generate an invalid uImage if it is run with
the parallel option (-j).

You can reproduce this problem with the following procedure:

[1] First, build "all" and "uImage" separately.
    You will get a valid uImage

  $ git clean -f -x -d
  $ export CROSS_COMPILE=<your-tools-prefix>
  $ make -s -j8 ARCH=arm multi_v7_defconfig
  $ make -s -j8 ARCH=arm all
  $ make -j8 ARCH=arm UIMAGE_LOADADDR=0x80208000 uImage

[2] Update some source file(s)

  $ touch init/main.c

[3] Then, re-build "all" and "uImage" simultaneously.
    You will get an invalid uImage at random.

  $ make -j8 ARCH=arm UIMAGE_LOADADDR=0x80208000 all uImage

Please notice the uImage is extremely small when this issue is
encountered.  Besides, "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, before and after the uImage log.

The root cause of this is the race condition between zImage and
uImage.  Actually, uImage depends on zImage, but the dependency
between the two is only described in arch/arm/boot/Makefile.
Because arch/arm/boot/Makefile is not included from the top-level
Makefile, it cannot know the dependency between zImage and uImage.

Consequently, when we run make with the parallel option, Kbuild
updates vmlinux first, and then two different threads descends into
the arch/arm/boot/Makefile almost at the same time, one for updating
zImage and the other for uImage.  While one thread is re-generating
zImage, the other also tries to update zImage before creating uImage
on top of that.  zImage is overwritten by the slower thread and then
uImage is created based on the half-written zImage.

This is the reason why "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, and a broken uImage is created.

The same problem could happen on bootpImage.

This commit adds dependencies among Image, zImage, uImage, and
bootpImage to arch/arm/Makefile, which is included from the
top-level Makefile.

Joachim Eastwood e8d235d4d8 ARM: lpc18xx: add basic support for NXP LPC18xx/43xx SoCs
Add support for NXP's LPC18xx (Cortex-M3) and LPC43xx (Cortex-M4)
SoCs. These SoCs are NXP's high preformance MCU line and can run at
clock speeds up to 180 MHz for LPC18xx and 204 MHz for LPC43xx.

LPC43xx is more or less a LPC18xx with a Cortex-M4F core and a few
extra peripherals. The LPC43xx series also features one or two
Cortex-M0 cores that can be used to offload the main M4 core.

Ard Biesheuvel 7d485f647c ARM: 8220/1: allow modules outside of bl range
Loading modules far away from the kernel in memory is problematic
because the 'bl' instruction only has limited reach, and modules are not
built with PLTs. Instead of using the -mlong-calls option (which affects
all compiler emitted bl instructions, but not the ones in assembler),
this patch allocates some additional space at module load time, and
populates it with PLT like veneers when encountering relocations that
are out of range.

This should work with all relocations against symbols exported by the
kernel, including those resulting from GCC generated implicit function
calls for ftrace etc.

The module memory size increases by about 5% on average, regardless of
whether any PLT entries were actually needed. However, due to the page
based rounding that occurs when allocating module memory, the average
memory footprint increase is negligible.

   support
 - OMAP removes legacy board files for three more platforms
 - Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
 - Freescale i.MX25 also removes non-DT platform support

Ard Biesheuvel 02e541db05 ARM: 8323/1: force linker to use PIC veneers
When building a very large kernel, it is up to the linker to decide
when and where to insert stubs to allow calls to functions that are
out of range for the ordinary b/bl instructions.

However, since the kernel is built as a position dependent binary,
these stubs (aka veneers) may contain absolute addresses, which will
break far calls performed with the MMU off.

For instance, the call from __enable_mmu() in the .head.text section
to __turn_mmu_on() in the .idmap.text section may be turned into
something like this:

c0008168 <__enable_mmu>:
c0008168:       f020 0002       bic.w   r0, r0, #2
c000816c:       f420 5080       bic.w   r0, r0, #4096
c0008170:       f000 b846       b.w     c0008200 <____turn_mmu_on_veneer>
[...]
c0008200 <____turn_mmu_on_veneer>:
c0008200:       4778            bx      pc
c0008202:       46c0            nop
c0008204:       e59fc000        ldr     ip, [pc]
c0008208:       e12fff1c        bx      ip
c000820c:       c13dfae1        teqgt   sp, r1, ror #21
[...]
c13dfae0 <__turn_mmu_on>:
c13dfae0:       4600            mov     r0, r0
[...]

After adding --pic-veneer to the LDFLAGS, the veneer is emitted like
this instead:

c0008200 <____turn_mmu_on_veneer>:
c0008200:       4778            bx      pc
c0008202:       46c0            nop
c0008204:       e59fc004        ldr     ip, [pc, #4]
c0008208:       e08fc00c        add     ip, pc, ip
c000820c:       e12fff1c        bx      ip
c0008210:       013d7d31        teqeq   sp, r1, lsr sp
c0008214:       00000000        andeq   r0, r0, r0

Note that this particular example is best addressed by moving
.head.text and .idmap.text closer together, but this issue could
potentially affect any code that needs to execute with the
MMU off.

'#include' directives are also midified to '#include <asm/patch.h>'.

Syntactically FOOTBRIDGE and ARCH_FOOTBRIDGE are identical (the former
is defined in an if ARCH_FOOTBRIDGE block and the latter selects the
former).

Sematically FOOTBRIDGE means "we have a DC21285 (aka footbridge) device
in the system" and ARCH_FOOTBRIDGE is the support for boards with a
footbridge device, so ARCH_FOOTBRIDGE is the better symbol here.

Linus Torvalds b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

These cleanup patches are mainly move stuff around and should all

 be based on top to avoid conflicts.
 
 Notable changes are:
 
 * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
   longer used. (Uwe Kleine-König)
 * The Qualcomm MSM platform is split out into legacy mach-msm and
   new-style mach-qcom, to allow easier maintainance of the new
   hardware support without regressions. (Kumar Gala)
 * A rework of some of the Kconfig logic to simplify multiplatform
   support (Rob Herring)
 * Samsung Exynos gets closer to supporting multiplatform (Sachin
   Kamat and others)
 * mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
 * at91 gains some common clock framework support (Alexandre Belloni,

Pull ARM SoC cleanups from Arnd Bergmann:
 "These cleanup patches are mainly move stuff around and should all be
  harmless.  They are mainly split out so that other branches can be
  based on top to avoid conflicts.

  Notable changes are:

   - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
     longer used (Uwe Kleine-König)
   - The Qualcomm MSM platform is split out into legacy mach-msm and
     new-style mach-qcom, to allow easier maintainance of the new
     hardware support without regressions (Kumar Gala)
   - A rework of some of the Kconfig logic to simplify multiplatform
     support (Rob Herring)
   - Samsung Exynos gets closer to supporting multiplatform (Sachin
     Kamat and others)
   - mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
   - at91 gains some common clock framework support (Alexandre Belloni,
     Jean-Jacques Hiblot and other French people)"

Jason Cooper f4d4ffc03e kbuild: dtbs_install: new make target
Unlike other build products in the Linux kernel, there is no 'make
*install' mechanism to put devicetree blobs in a standard place.

This commit adds a new 'dtbs_install' make target which copies all of
the dtbs into the INSTALL_DTBS_PATH directory. INSTALL_DTBS_PATH can be
set before calling make to change the default install directory. If not
set then it defaults to:

	$INSTALL_PATH/dtbs/$KERNELRELEASE.

This is done to keep dtbs from different kernel versions separate until
things have settled down.  Once the dtbs are stable, and not so strongly
linked to the kernel version, the devicetree files will most likely move
to their own repo.  Users will need to upgrade install scripts at that
time.

v7: (reworked by Grant Likely)
- Moved rules from arch/arm/Makefile to arch/arm/boot/dts/Makefile so
  that each dtb install could have a separate target and be reported as
  part of the make output.
- Fixed dependency problem to ensure $KERNELRELEASE is calculated before
  attempting to install
- Removed option to call external script. Copying the files should be
  sufficient and a build system can post-process the install directory.
  Despite the fact an external script is used for installing the kernel,
  I don't think that is a pattern that should be encouraged. I would
  rather see buildroot type tools post process the install directory to
  rename or move dtb files after installing to a staging directory.
  - Plus it is easy to add a hook after the fact without blocking the
    rest of this feature.
- Move the helper targets into scripts/Makefile.lib with the rest of the
  common dtb rules

Linus Torvalds 0ba3307a8e ARM: driver updates for 3.14
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

Haojian Zhuang 389ee0c2ff ARM: hisi: rename hi3xxx to hisi
Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx
to mach-hisi instead. And the pronounciation of "hisi" is similar to the
chinese pronounciation of Hisilicon. So Hisilicon guys like this name.

ARCH_HI3xxx will be renamed later since other drivers are using it and
they are still in linux-next git tree. So rename ARCH_HI3xxx later.

Kees Cook 19952a9203 stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures
Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.

Alexandre Courbot d9a1beaa10 ARM: add basic support for Trusted Foundations
Trusted Foundations is a TrustZone-based secure monitor for ARM that
can be invoked using the same SMC-based API on supported platforms.
This patch adds initial basic support for Trusted Foundations using
the ARM firmware API. Current features are limited to the ability to
boot secondary processors.

Note: The API followed by Trusted Foundations does *not* follow the SMC
calling conventions. It has nothing to do with PSCI neither and is only
relevant to devices that use Trusted Foundations (like most Tegra-based
retail devices).
