Arch code may have asm implementation of string/memory API functions
instead of using generic one from lib/string.c. KASAN don't see memory
accesses in asm code, thus can miss many bugs.
E.g. on ARM64 KASAN don't see bugs in memchr(), memcmp(), str[r]chr(),
str[n]cmp(), str[n]len(). Add tests for these functions to be sure that
we notice the problem on other architectures.

Ifdef out __HAVE_ARCH_* defines of these functions when KASAN is enabled,
so the generic implementations from lib/string.c will be used.
We can't just remove the asm functions because efistub uses them. And we
can't have two non-weak functions either, so declare the asm functions as
weak.

Tracing the event "fs_dax:dax_pmd_insert_mapping" with perf produces this
warning:
[fs_dax:dax_pmd_insert_mapping] unknown op '~'
It is printed in process_op (tools/lib/traceevent/event-parse.c) because
'~' is parsed as a binary operator.
perf reads the format of fs_dax:dax_pmd_insert_mapping ("print fmt") from
/sys/kernel/debug/tracing/events/fs_dax/dax_pmd_insert_mapping/format .
The format contains:
~(((u64) ~(~(((1UL) << 12)-1)))
^
\ interpreted as a binary operator by process_op().
This part is generated in the declaration of the event class
dax_pmd_insert_mapping_class in include/trace/events/fs_dax.h :
__print_flags_u64(__entry->pfn_val & PFN_FLAGS_MASK, "|",
PFN_FLAGS_TRACE),
This patch adds a pair of parentheses in the declaration of PFN_FLAGS_MASK
to make sure that '~' is parsed as a unary operator by perf.
The part of the format that was problematic is now:
~(((u64) (~(~(((1UL) << 12)-1))))
Now, all the '~' are parsed as unary operators.

userfaultfd contains howe-grown locking of the waitqueue lock, and does
not disable interrupts. This relies on the fact that no one else takes it
from interrupt context and violates an invariat of the normal waitqueue
locking scheme. With aio poll it is easy to trigger other locks that
disable interrupts (or are called from interrupt context).

This patch set contains a lot (at least, for me) of improvements to the
RISC-V kernel port:
* The removal of some cacheinfo values that were bogus.
* On systems with F but without D the kernel will not show the F
extension to userspace, as it isn't actually supported.
* Support for futexes.
* Removal of some unused code.
* Cleanup of some menuconfig entries.
* Support for systems without a floating-point unit, and for building
kernels that will never use the floating-point unit.
* More fixes to the RV32I port, which regressed again. It's really time
to get this into a regression test somewhere so I stop breaking it.
Thanks to Zong for resurrecting it again!
* Various fixes that resulted from a year old review of our original
patch set that I finally got around to.
* Various improvements to SMP support, largely based around having
switched to logical hart numbering, as well as some interrupt
improvements. This one is in the same patch set as above, thanks to
Atish for sheparding everything though as my patch set was a bit of a
mess.
I'm pretty sure this is our largest patch set since the original kernel
contribution, and it's certainly the one with the most contributors.
While I don't have anything else I know I'm going to submit for the
merge window, I would be somewhat surprised if I didn't screw anything
up.
Thanks for the help, everyone!

Pull RISC-V updates from Palmer Dabbelt:
"This patch set contains a lot (at least, for me) of improvements to
the RISC-V kernel port:
- The removal of some cacheinfo values that were bogus.
- On systems with F but without D the kernel will not show the F
extension to userspace, as it isn't actually supported.
- Support for futexes.
- Removal of some unused code.
- Cleanup of some menuconfig entries.
- Support for systems without a floating-point unit, and for building
kernels that will never use the floating-point unit.
- More fixes to the RV32I port, which regressed again. It's really
time to get this into a regression test somewhere so I stop
breaking it. Thanks to Zong for resurrecting it again!
- Various fixes that resulted from a year old review of our original
patch set that I finally got around to.
- Various improvements to SMP support, largely based around having
switched to logical hart numbering, as well as some interrupt
improvements. This one is in the same patch set as above, thanks to
Atish for sheparding everything though as my patch set was a bit of
a mess.
I'm pretty sure this is our largest patch set since the original
kernel contribution, and it's certainly the one with the most
contributors. While I don't have anything else I know I'm going to
submit for the merge window, I would be somewhat surprised if I didn't
screw anything up.
Thanks for the help, everyone!"

Older versions of bintutils do not allow symbol math across different
segments on sparc:
====================
Assembler messages:
99: Error: operation combines symbols in different segments
====================
This is controlled by whether or not DIFF_EXPR_OK is defined in
gas/config/tc-*.h and for sparc this was not the case until mid-2017.
So we have to patch between %stick and %tick another way.
Do what powerpc does and emit two versions of the relevant functions,
one using %tick and one using %stick, and patch the symbols in the
dynamic symbol table.
Fixes: 2f6c9bf31a ("sparc: Improve VDSO instruction patching.")

There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly
small updates to the target subsystem a set of conversions to the
generic DMA API, which do have some potential for issues in the older
drivers but we'll handle those as case by case fixes. A new myrs for
the DAC960/mylex raid controllers to replace the block based DAC960
which is also being removed by Jens in this merge window. Plus the

some potential for issues in the older drivers but we'll handle those
as case by case fixes.
A new myrs driver for the DAC960/mylex raid controllers to replace the
block based DAC960 which is also being removed by Jens in this merge
window.
Plus the usual slew of trivial changes"
[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
wonder. There's also a "myrb" driver, where the 'b' stands for
'block'. Truly, somebody has got mad naming skillz. - Linus ]

In this round, we've added 1) superblock checksum feature, 2) implemented new
mount option which we can disable/enable checkpoint to provide atomic updates of
entire filesystem, 3) refactored quota operations to enhance its consistency
along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward
recovery flow to resurrect any fsync'ed inode metadata.
Enhancement:
- add checksum to keep superblock contents more safe
- add checkpoint=disable/enable to support A/B update of entire filesystem
- use plug for readahead IO in readdir
- add more IO counts to avoid block layer hacks
Bug fix:
- prevent data corruption issue for hardware encryption
- fix IO hang issues when GC is heavily triggered
- add missing up_read in __write_node_page
- recover inode metadata during roll-forward recovery flow
- fix null pointer dereference issue in wrongly configured discard map
There are some more sanity checks and minor bug fixes as well.

Merge tag 'xfs-4.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pul xfs updates from Dave Chinner:
"There's not a huge amount of change in this cycle - Darrick has been
out of action for a couple of months (hence me sending the last few
pull requests), so we decided a quiet cycle mainly focussed on bug
fixes was a good idea. Darrick will take the helm again at the end of
this merge window.
FYI, I may be sending another update later in the cycle - there's a
pending rework of the clone/dedupe_file_range code that fixes numerous
bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
reviewed and tested, Al and I just need to work out the details of the
merge, so it may come from him rather than me.
Summary:
- only support filesystems with unwritten extents
- add definition for statfs XFS magic number
- remove unused parameters around reflink code
- more debug for dangling delalloc extents
- cancel COW extents on extent swap targets
- fix quota stats output and clean up the code
- refactor some of the attribute code in preparation for parent
pointers
- fix several buffer handling bugs"
