Kernel v5.14 has various changes to optimize unaligned memory accesses,
e.g. commit 0652035a5794 ("asm-generic: unaligned: remove byteshift helpers").
Those changes triggered an unalignment-exception and thus crashed the
bootloader on parisc because the unaligned "output_len" variable now suddenly
was read word-wise while it was read byte-wise in the past.
Fix this issue by declaring the external output_len variable as char which then
forces the compiler to generate byte-accesses.

Commit 0e0345b77ac4 ("kbuild: redo fake deps at include/config/*.h")
simplified the Kconfig/fixdep interaction a lot.
For CONFIG_FOO_BAR_BAZ, Kconfig now touches include/config/FOO_BAR_BAZ
instead of the previous include/config/foo/bar/baz.h .
This commit simplifies the TRIM_UNUSED_KSYMS feature in a similar way:
- delete .h suffix
- delete tolower()
- put everything in 1 directory
For EXPORT_SYMBOL(FOO_BAR_BAZ), scripts/adjust_autoksyms.sh now touches
include/ksym/FOO_BAR_BAZ instead of include/ksym/foo/bar/baz.h .
This is more precise, avoiding possibly unnecessary rebuilds.
EXPORT_SYMBOL(FOO_BAR_BAZ)
EXPORT_SYMBOL(_FOO_BAR_BAZ)
EXPORT_SYMBOL(__FOO_BAR_BAZ)
were previously mapped to the same header, include/ksym/foo/bar/baz.h
but now are handled separately.

get_src_version() strips 'o' or 'lto.o' from the end of the object file
path (so, postfixlen is 1 or 5), then adds 'mod'.
If you look at the code closely, mod->name already holds the base path
with the extension stripped.
Most of the code changes made by commit 7ac204b545f2 ("modpost: lto:
strip .lto from module names") was actually unneeded.
sumversion.c does not need strends(), so it can get back local in
modpost.c again.

It seems like the implementation of the --ignore option is broken.
In check_symbols_helper, when going through the list of files, a file is
added to the list of source files to check if it matches the ignore
pattern. Instead, as stated in the comment below this condition, the
file should be added if it doesn't match the pattern.
This means that when providing an ignore pattern, the only files that
will be checked will be the ones we want the ignore, in addition to the
Kconfig files that don't match the pattern (the check in
parse_kconfig_files is done right)

cmd_update_lto_symversions merges all the existing *.symversions, but
some of them might be stale.
If the last EXPORT_SYMBOL is removed from a C file, the *.symversions
file is not deleted or updated. It contains stale CRCs, but still they
will be used for linking the vmlinux or modules.
It is not a big deal when the EXPORT_SYMBOL is really removed. However,
when the EXPORT_SYMBOL is moved to another file, the same __crc_<symbol>
will appear twice in the merged *.symversions, possibly with different
CRCs if the function argument is changed at the same time. It would
confuse module versioning.
If no EXPORT_SYMBOL is found, let's remove *.symversions explicitly.

The current gen_compile_commands.py assumes that objects are always
built by a single command.
It makes sense to support cases where objects are built by a series of
commands:
cmd_<object> := <command1> ; <command2>
One use-case is that <command1> is a compiler command, and <command2>
an objtool command.
It allows *.cmd files to contain an objtool command so that any change
in it triggers object rebuilds.
If ; appears after the C source file, take the first command.

It has been brought up a few times in various code reviews that clang
3.5 introduced -f{,no-}integrated-as as the preferred way to enable and
disable the integrated assembler, mentioning that -{no-,}integrated-as
are now considered legacy flags.
Switch the kernel over to using those variants in case there is ever a
time where clang decides to remove the non-'f' variants of the flag.
Also, fix a typo in a comment ("intergrated" -> "integrated").

With CONFIG_LTO_CLANG, we currently link modules into native
code just before modpost, which means with TRIM_UNUSED_KSYMS
enabled, we still look at the LLVM bitcode in the .o files when
generating the list of used symbols. As the bitcode doesn't
yet have calls to compiler intrinsics and llvm-nm doesn't see
function references that only exist in function-level inline
assembly, we currently need a whitelist for TRIM_UNUSED_KSYMS to
work with LTO.
This change moves module LTO linking to happen earlier, and
thus avoids the issue with LLVM bitcode and TRIM_UNUSED_KSYMS
entirely, allowing us to also drop the whitelist from
gen_autoksyms.sh.

cc-option, cc-option-yn, and cc-disable-warning all invoke the compiler

stale for our supported compilers, whose minimally supported versions
increases over time. See Documentation/process/changes.rst for the
current supported minimal versions (GCC 4.9+, clang 10.0.1+). Compiler
version support for these flags may be verified on godbolt.org.
The following flags are GCC only and supported since at least GCC 4.9.
Remove cc-option and cc-disable-warning tests.
* -fno-tree-loop-im
* -Wno-maybe-uninitialized
* -fno-reorder-blocks
* -fno-ipa-cp-clone
* -fno-partial-inlining
* -femit-struct-debug-baseonly
* -fno-inline-functions-called-once
* -fconserve-stack
The following flags are supported by all supported versions of GCC and
Clang. Remove their cc-option, cc-option-yn, and cc-disable-warning tests.
* -fno-delete-null-pointer-checks
* -fno-var-tracking
* -Wno-array-bounds
The following configs are made dependent on GCC, since they use GCC
specific flags.
* READABLE_ASM
* DEBUG_SECTION_MISMATCH
-mfentry was not supported by s390-linux-gnu-gcc until gcc-9+, add a
comment.
--param=allow-store-data-races=0 was renamed to -fno-allow-store-data-races
in the GCC 10 release; add a comment.
-Wmaybe-uninitialized (GCC specific) was being added for CONFIG_GCOV,
then again unconditionally; add it only once.
Also, base RETPOLINE_CFLAGS and RETPOLINE_VDSO_CFLAGS on CONFIC_CC_IS_*

Pull rdma updates from Jason Gunthorpe:
"This is quite a small cycle, no major series stands out. The HNS and
rxe drivers saw the most activity this cycle, with rxe being broken
for a good chunk of time. The significant deleted line count is due to
a SPDX cleanup series.
Summary:
- Various cleanup and small features for rtrs
- kmap_local_page() conversions
- Driver updates and fixes for: efa, rxe, mlx5, hfi1, qed, hns
- Cache the IB subnet prefix
- Rework how CRC is calcuated in rxe
- Clean reference counting in iwpm's netlink
- Pull object allocation and lifecycle for user QPs to the uverbs
core code

Pull clk updates from Stephen Boyd:
"Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
divider type and add a power of two fractional divider flag though.
Otherwise, this is a collection of clk driver updates. More than half
the diffstat is in the Qualcomm clk driver where we add a bunch of
data to describe clks on various SoCs and fix bugs. The other big new
thing in here is the Mediatek MT8192 clk driver. That's been under
review for a while and it's nice to see that it's finally upstream.
Beyond that it's the usual set of minor fixes and tweaks to clk
drivers. There are some non-clk driver bits in here which have all
been acked by the respective maintainers.
New Drivers:
- Support video, gpu, display clks on qcom sc7280 SoCs
- GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
- Multimedia clks (MMCC) on qcom MSM8994/MSM8992
- RPMh clks on qcom SM6350 SoCs
- Support for Mediatek MT8192 SoCs
- Add display (DU and DSI) clocks on Renesas R-Car V3U
- Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
resets on Renesas RZ/G2L
Updates:
- Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
- Add power of two flag to fractional divider clk type
- Migrate some clk drivers to clk_divider_ops.determine_rate
- Migrate to clk_parent_data in gcc-sdm660
- Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
- Switch from .round_rate to .determine_rate in clk-divider-gate
- Fix clock tree update for TF-A controlled clocks for all i.MX8M
- Add missing M7 core clock for i.MX8MN
- YAML conversion of rk3399 clock controller binding
- Removal of GRF dependency for the rk3328/rk3036 pll types
- Drop CLK_IS_CRITICAL flag from Tegra fuse clk
- Make CLK_R9A06G032 Kconfig symbol invisible

For example in the case of a forced umount, we'll remove all the session
caps even if they are dirty. Move the warning to a wrapper function and
make most of the callers use it. Call the core function when removing
caps due to a forced umount.

capsnaps will take inode references via ihold when queueing to flush.
When force unmounting, the client will just close the sessions and
may never get a flush reply, causing a leak and inode ref leak.
Fix this by removing the capsnaps for an inode when removing the caps.

The current code will update the mtime and then try to get caps to
handle the write. If we end up having to request caps from the MDS, then
the mtime in the cap grant will clobber the updated mtime and it'll be
lost.
This is most noticable when two clients are alternately writing to the
same file. Fw caps are continually being granted and revoked, and the
mtime ends up stuck because the updated mtimes are always being
overwritten with the old one.
Fix this by changing the order of operations in ceph_write_iter to get
the caps before updating the times. Also, make sure we check the pool
full conditions before even getting any caps or uninlining.
