- boot_mem_map is removed, providing a nice cleanup made possible by the
recent removal of bootmem.
- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
MIPS32 systems using cmpxchg64().
- Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
Frascino.
- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.
- Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
- pte_special() is now supported for some configurations, allowing among
other things generic fast GUP to be used.
- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil, mostly
enabled by the inclusion of the new TCU (timer-counter unit) drivers
he's spent a very patient year or so working on. Plus some fixes for
X1000 SoCs from Zhou Yanjie.
- Netgear R6200 v1 systems are now supported by the bcm47xx platform.
- DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

e2fsck detects and fixes this issue for the past four years, it'e time

This is more cleanup and consolidation of the hmm APIs and the very
strongly related mmu_notifier interfaces. Many places across the tree
using these interfaces are touched in the process. Beyond that a cleanup
to the page walker API and a few memremap related changes round out the
series:
- General improvement of hmm_range_fault() and related APIs, more
documentation, bug fixes from testing, API simplification &
consolidation, and unused API removal
- Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
make them internal kconfig selects
- Hoist a lot of code related to mmu notifier attachment out of drivers by
using a refcount get/put attachment idiom and remove the convoluted
mmu_notifier_unregister_no_release() and related APIs.
- General API improvement for the migrate_vma API and revision of its only
user in nouveau
- Annotate mmu_notifiers with lockdep and sleeping region debugging
Two series unrelated to HMM or mmu_notifiers came along due to
dependencies:
- Allow pagemap's memremap_pages family of APIs to work without providing
a struct device
- Make walk_page_range() and related use a constant structure for function

gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise
crude heuristic that gcc uses to estimate the size of the code
represented by an asm() statement. From the gcc docs
If you use 'asm inline' instead of just 'asm', then for inlining
purposes the size of the asm is taken as the minimum size, ignoring
how many instructions GCC thinks it is.
For compatibility with older compilers, we obviously want a
#if [understands asm inline]
#define asm_inline asm inline
#else
#define asm_inline asm
#endif
But since we #define the identifier inline to attach some attributes,
we have to use an alternate spelling of that keyword. gcc provides
both __inline__ and __inline, and we currently #define both to inline,
so they all have the same semantics. We have to free up one of
__inline__ and __inline, and the latter is by far the easiest.
The two x86 changes cause smaller code gen differences than I'd
expect, but I think we do want the asm_inline thing available sooner
or later, so this is just to get the ball rolling.

"Make use of gcc 9's "asm inline()" (Rasmus Villemoes):
gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise
crude heuristic that gcc uses to estimate the size of the code
represented by an asm() statement. From the gcc docs
If you use 'asm inline' instead of just 'asm', then for inlining
purposes the size of the asm is taken as the minimum size, ignoring
how many instructions GCC thinks it is.
For compatibility with older compilers, we obviously want a
#if [understands asm inline]
#define asm_inline asm inline
#else
#define asm_inline asm
#endif
But since we #define the identifier inline to attach some attributes,
we have to use an alternate spelling of that keyword. gcc provides
both __inline__ and __inline, and we currently #define both to inline,
so they all have the same semantics.
We have to free up one of __inline__ and __inline, and the latter is
by far the easiest.
The two x86 changes cause smaller code gen differences than I'd
expect, but I think we do want the asm_inline thing available sooner
or later, so this is just to get the ball rolling"

This is some material that we picked up into our tree late or
that had complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the most
interesting new additions:
The new Aspeed AST2600 baseboard management controller is added, this
is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
dependencies on other device drivers.
After many years, support for the MMP2 based OLPC XO-1.75 finally makes
it into the kernel.
The Armada 3720 based Turris Mox open source router platform is a late
addition and it follows some preparatory work across multiple branches.
The OMAP2+ platform had some large-scale cleanup involving driver
changes and DT changes, here we finish it off, dropping a lot of the
now-unused platform data.
The TI K3 platform that got added for 5.3 gains a lot more support
for individual bits on the SoC, this part just came late for the

clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:
- Add regulator support to the cdce925 clk driver
- Add support for Raspberry Pi 4 bcm2711 SoCs
- Add SDIO gate support to aspeed driver
- Add missing of_node_put() calls in various clk drivers
- Migrate Amlogic driver to new clock parent description method
- Add DVFS support to Amlogic Meson g12
- Add Amlogic Meson g12a reset support to the axg audio clock controller
- Add sm1 support to the Amlogic Meson g12a clock controller

2 recent commits have fixed issues where _PFN_SHIFT grew too large due
to the introduction of too many pgprot bits in our PTEs for some MIPS32
kernel configurations. Tracking down such issues can be tricky, so add a
BUILD_BUG_ON() to help.

Commit 61cbfff4b1 ("MIPS: pte_special()/pte_mkspecial() support")
added a _PAGE_SPECIAL bit to the pgprot bits of our PTEs. Unfortunately
for MIPS32 configurations with RiXi support this pushed the number of
pgprot bits to 13. Since the PFN field in EntryLo begins at bit 12 this
results in us shifting the most significant bit of the physical address
beyond the end of the PTE, leading any mapped access to a physical
address above 2GB to incorrectly access an address 2GB lower than
intended.
For now, disable the pte_special() support for MIPS32 configurations
that support RiXi.

- Initial support for running on a system with an Ultravisor, which is software
that runs below the hypervisor and protects guests against some attacks by
the hypervisor.
- Support for building the kernel to run as a "Secure Virtual Machine", ie. as
a guest capable of running on a system with an Ultravisor.
- Some changes to our DMA code on bare metal, to allow devices with medium
sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space.
- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas macros, both
to make it more readable and also enable some future optimisations.
As well as many cleanups and other minor features & fixups.

Pull powerpc updates from Michael Ellerman:
"This is a bit late, partly due to me travelling, and partly due to a
power outage knocking out some of my test systems *while* I was
travelling.
- Initial support for running on a system with an Ultravisor, which
is software that runs below the hypervisor and protects guests
against some attacks by the hypervisor.
- Support for building the kernel to run as a "Secure Virtual
Machine", ie. as a guest capable of running on a system with an
Ultravisor.
- Some changes to our DMA code on bare metal, to allow devices with
medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of
DMA space.
- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas
macros, both to make it more readable and also enable some future
optimisations.
As well as many cleanups and other minor features & fixups.

It has been a quiet dev cycle for kgdb. There has been some good stuff
for kdb on the mailing list but unfortunately the patches caused a
couple of problems with the kdb pager so I had to drop those and they
will have to wait for next time!
That just leaves us with just a couple of very tiny clean ups for now:

* Use str_has_prefix() for the grep "pipe" in kdb

Pull drm updates from Dave Airlie:
"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the
week but got delayed writing summary and sending it out, due to a mix
of sick kid and jetlag!
There are some fixes pending, but I'd rather get the main merge out of
the way instead of delaying it longer.
It's also pretty large in commit count and new amd header file size.
The largest thing is four new amdgpu products (navi12/14, arcturus and
renoir APU support).
Otherwise it's pretty much lots of work across the board, i915 has
started landing tigerlake support, lots of icelake fixes and lots of
locking reworking for future gpu support, lots of header file rework
(drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
put into the places they are needed.

callers are always looping through lists and therefore the pointers
can't be NULL. Drop the checks to simplify the code.

orangefs: remove redundant assignment to err
orangefs: Add octal zero prefix
Pull autofs updates from Al Viro:
"The most interesting part here is getting rid of the last trylock loop
on dentry->d_lock.
The ones in fs/dcache.c had been dealt with several years ago, but
there'd been leftovers in fs/autofs/expire.c"
* 'work.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
autofs_lookup(): hold ->d_lock over playing with ->d_flags
get rid of autofs_info->active_count
autofs: simplify get_next_positive_...(), get rid of trylocks
Pull misc mount API conversions from Al Viro:
"Conversions to new API for shmem and friends and for mount_mtd()-using
filesystems.
As for the rest of the mount API conversions in -next, some of them
belong in the individual trees (e.g. binderfs one should definitely go
through android folks, after getting redone on top of their changes).
I'm going to drop those and send the rest (trivial ones + stuff ACKed
by maintainers) in a separate series - by that point they are
independent from each other.
Some stuff has already migrated into individual trees (NFS conversion,
for example, or FUSE stuff, etc.); those presumably will go through
the regular merges from corresponding trees."
* 'work.mount2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
vfs: Make fs_parse() handle fs_param_is_fd-type params better
vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount API
shmem_parse_one(): switch to use of fs_parse()
shmem_parse_options(): take handling a single option into a helper
shmem_parse_options(): don't bother with mpol in separate variable
shmem_parse_options(): use a separate structure to keep the results
make shmem_fill_super() static
make ramfs_fill_super() static
devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()
vfs: Convert squashfs to use the new mount API
mtd: Kill mount_mtd()
vfs: Convert jffs2 to use the new mount API
vfs: Convert cramfs to use the new mount API
vfs: Convert romfs to use the new mount API
vfs: Add a single-or-reconfig keying to vfs_get_super()
This series from Deepa Dinamani adds a per-superblock minimum/maximum
timestamp limit for a file system, and clamps timestamps as they are
written, to avoid random behavior from integer overflow as well as having
different time stamps on disk vs in memory.
At mount time, a warning is now printed for any file system that can
represent current timestamps but not future timestamps more than 30
years into the future, similar to the arbitrary 30 year limit that was
added to settimeofday().
This was picked as a compromise to warn users to migrate to other file
systems (e.g. ext4 instead of ext3) when they need the file system to
survive beyond 2038 (or similar limits in other file systems), but not
get in the way of normal usage.
