98eb8d9502 iomap: set did_zero to true when zeroing successfully 
It is unnecessary to check and set did_zero value in while() loop
in iomap_zero_iter(), we can set did_zero to true only when zeroing
successfully at last.

d58562ca6c iomap: skip pages past eof in iomap_do_writepage() 
iomap_do_writepage() sends pages past i_size through
folio_redirty_for_writepage(), which normally isn't a problem because
truncate and friends clean them very quickly.

When the system has cgroups configured, we can end up in situations
where one cgroup has almost no dirty pages at all, and other cgroups
consume the entire background dirty limit.  This is especially common in
our XFS workloads in production because they have cgroups using O_DIRECT
for almost all of the IO mixed in with cgroups that do more traditional
buffered IO work.

We've hit storms where the redirty path hits millions of times in a few
seconds, on all a single file that's only ~40 pages long.  This leads to
long tail latencies for file writes because the pdflush workers are
hogging the CPU from some kworkers bound to the same CPU.

Reproducing this on 5.18 was tricky because 869ae85dae ("xfs: flush new
eof page on truncate...") ends up writing/waiting most of these dirty pages
before truncate gets a chance to wait on them.

The actual repro looks like this:

/*
 * run me in a cgroup all alone.  Start a second cgroup with dd
 * streaming IO into the block device.
 */
int main(int ac, char **av) {
	int fd;
	int ret;
	char buf[BUFFER_SIZE];
	char *filename = av[1];

	memset(buf, 0, BUFFER_SIZE);

	if (ac != 2) {
		fprintf(stderr, "usage: looper filename\n");
		exit(1);
	}
	fd = open(filename, O_WRONLY | O_CREAT, 0600);
	if (fd < 0) {
		err(errno, "failed to open");
	}
	fprintf(stderr, "looping on %s\n", filename);
	while(1) {
		/*
		 * skip past page 0 so truncate doesn't write and wait
		 * on our extent before changing i_size
		 */
		ret = lseek(fd, 8192, SEEK_SET);
		if (ret < 0)
			err(errno, "lseek");
		ret = write(fd, buf, BUFFER_SIZE);
		if (ret != BUFFER_SIZE)
			err(errno, "write failed");
		/* start IO so truncate has to wait after i_size is 0 */
		ret = sync_file_range(fd, 16384, 4095, SYNC_FILE_RANGE_WRITE);
		if (ret < 0)
			err(errno, "sync_file_range");
		ret = ftruncate(fd, 0);
		if (ret < 0)
			err(errno, "truncate");
		usleep(1000);
	}
}

And this bpftrace script will show when you've hit a redirty storm:

kretprobe:xfs_vm_writepages {
    delete(@dirty[pid]);
}

kprobe:xfs_vm_writepages {
    @dirty[pid] = 1;
}

kprobe:folio_redirty_for_writepage /@dirty[pid] > 0/ {
    $inode = ((struct folio *)arg1)->mapping->host->i_ino;
    @inodes[$inode] = count();
    @redirty++;
    if (@redirty > 90000) {
        printf("inode %d redirty was %d", $inode, @redirty);
        exit();
    }
}

This patch has the same number of failures on xfstests as unpatched 5.18:
Failures: generic/648 xfs/019 xfs/050 xfs/168 xfs/299 xfs/348 xfs/506
xfs/543

I also ran it through a long stress of multiple fsx processes hammering.

(Johannes Weiner did significant tracing and debugging on this as well)

 "Fixes addressing important multichannel, and reconnect issues.

  Multichannel mounts when the server network interfaces changed, or ip
  addresses changed, uncovered problems, especially in reconnect, but
  the patches for this were held up until recently due to some lock
  conflicts that are now addressed.

  Included in this set of fixes:

   - three fixes relating to multichannel reconnect, dynamically
     adjusting the list of server interfaces to avoid problems during
     reconnect

   - a lock conflict fix related to the above

   - two important fixes for negotiate on secondary channels (null
     netname can unintentionally cause multichannel to be disabled to
     some servers)

   - a reconnect fix (reporting incorrect IP address in some cases)"

448ce0e6ea perf stat: Enable ignore_missing_thread 
perf already support ignore_missing_thread for -p, but not yet
applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread
for `perf stat -p <pid>`.

Committer notes:

And here is a refresher about the 'ignore_missing_thread' knob, from a
previous patch using it:

  ca8000684e ("perf evsel: Enable ignore_missing_thread for pid option")

  ---
    While monitoring a multithread process with pid option, perf sometimes
    may return sys_perf_event_open failure with 3(No such process) if any of
    the process's threads die before we open the event. However, we want
    perf continue monitoring the remaining threads and do not exit with
    error.

37ed2cddcb perf inject: Adjust output data offset for backward compatibility 
When 'perf inject' creates a new file, it reuses the data offset from
the input file. If there has been a change on the size of the header, as
happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
a corrupted output file.

This change adds the function perf_session__data_offset to compute the
data offset based on the current header size, and uses that instead of
the offset from the original input file.

ab66fdace8 perf build-id: Fix caching files with a wrong build ID 
Build ID events associate a file name with a build ID.  However, when
using perf inject, there is no guarantee that the file on the current
machine at the current time has that build ID. Fix by comparing the
build IDs and skip adding to the cache if they are different.

Example:

  $ echo "int main() {return 0;}" > prog.c
  $ gcc -o prog prog.c
  $ perf record --buildid-all ./prog
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.019 MB perf.data ]
  $ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; }
  $ file-buildid prog
  444ad9be165d8058a48ce2ffb4e9f55854a3293e
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
  444ad9be165d8058a48ce2ffb4e9f55854a3293e
  $ echo "int main() {return 1;}" > prog.c
  $ gcc -o prog prog.c
  $ file-buildid prog
  885524d5aaa24008a3e2b06caa3ea95d013c0fc5

Before:

  $ perf buildid-cache --purge $(pwd)/prog
  $ perf inject -i perf.data -o junk
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
  885524d5aaa24008a3e2b06caa3ea95d013c0fc5
  $

After:

  $ perf buildid-cache --purge $(pwd)/prog
  $ perf inject -i perf.data -o junk
  $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf

Fix a boot crash on a c8000 machine as reported by Dave.  Basically it changes
patch_map() to return an alias mapping to the to-be-patched code in order to
prevent writing to write-protected memory.

e9ed22e6e5 parisc: Fix flush_anon_page on PA8800/PA8900 
Anonymous pages are allocated with the shared mappings colouring,
SHM_COLOUR. Since the alias boundary on machines with PA8800 and
PA8900 processors is unknown, flush_user_cache_page() might not
flush all mappings of a shared anonymous page. Flushing the whole
data cache flushes all mappings.

This won't fix all coherency issues with shared mappings but it
seems to work well in practice.  I haven't seen any random memory
faults in almost a month on a rp3440 running as a debian buildd
machine.

There is a small preformance hit.

53632ba87d kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS (2nd attempt) 
If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from
a pristine state, the vmlinux is linked twice.

Commit 3fdc7d3fe4 ("kbuild: link vmlinux only once for
CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix
the issue at all.

Now I realized I had applied a wrong patch.

In v1 patch [1], the autoksyms_recursive target correctly recurses to
"$(MAKE) -f $(srctree)/Makefile autoksyms_recursive".

In v2 patch [2], I accidentally dropped the diff line, and it recurses to
"$(MAKE) -f $(srctree)/Makefile vmlinux".

Restore the code I intended in v1.

0840a7914c IIO driver fixes for 5.19-rc4 
Here are a set of IIO driver fixes for 5.19-rc4.  Jonathan said it best
 in his pull request to me, so I'll just quote it here below, as that's
 the only changes we have right now for the char-misc driver tree:
 
     1st set of IIO fixes for the 5.19 cycle.
 
     Most of these have been in next for a long time. Unfortunately there
     was one stray patch in the branch (wasn't a fix), so I've just rebased
     to remove that.
 
     * testing
       - Fix a missing MODULE_LICENSE() warning by restricting possible build
         configs.
     * Various drivers
       - Fix ordering of iio_get_trigger() being called before
         iio_trigger_register()
     * adi,admv1014
       - Fix dubious x & !y warning.
     * adi,axi-adc
       - Fix missing of_node_put() in error and normal paths.
     * aspeed,adc
       - Add missing of_node_put()
     * fsl,mma8452
       - Fix broken probing from device tree.
       - Drop check on return value of i2c write to device to cause reset as
         ACK will be missing (device reset before sending it).
     * fsl,vf610
       - Fix documentation of in_conversion_mode ABI.
     * iio-trig-sysfs
       - Ensure irq work has finished before freeing the trigger.
     * invensense,mpu3050
      - Disable regulators in error path.
     * invensense,icm42600
       - Fix collision of enum value of 0 with error path where 0 is no match.
     * renesas,rzg2l_Adc
       - Add missing fwnode_handle_put() in error path.
     * rescale
       - Fix a boolean logic bug for detection of raw + scale affecting an
         obscure corner case.
     * semtech,sx9324
       - Check return value of read of pin_defs
     * st,stm32-adc:
       - Fix interaction across ADC instances for some supported devices.
       - Drop false spurious IRQ messages.
       - Fix calibration value handling.  If we can't calibrate don't expose the
         vref_int channel.
       - Fix maximum clock rate for stm32pm15x
     * ti,ads131e08
       - Add missing fwnode_handle_put() in error paths.
     * xilinx,ams
       - Fix variable checked for error from platform_get_irq()
     * x-powers,axp288
       - Overide TS_PIN bias current for boards where it is not correctly
         initialized.
     * yamaha,yas530
       - Fix inverted check on calibration data being all zeros.
 
 All of these have been in linux-next for a while with no reported
 problems.

Pull s390 fixes from Alexander Gordeev:

 - Fix perf stat accounting for cryptography counters when multiple
   events are installed concurrently.

 - Prevent installation of unsupported perf events for cryptography
   counters.

 - Treat perf events cpum_cf/CPU_CYCLES/ and cpu_cf/INSTRUCTIONS/
   identical to basic events CPU_CYCLES" and INSTRUCTIONS, since they
   address the same hardware.

 - Restore kcrash operation which was broken by commit 5d8de293c2
   ("vmcore: convert copy_oldmem_page() to take an iov_iter").

Merge tag 'drm-fixes-2022-06-24' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Fixes for this week, bit larger than normal, but I think the last
  couple have been quieter, and it's only rc4.

  There are a lot of small msm fixes, and a slightly larger set of vc4
  fixes. The vc4 fixes clean up a lot of crashes around the rPI4
  hardware differences from earlier ones, and problems in the page flip
  and modeset code which assumed earlier hw, so I thought it would be
  okay to keep them in.

  Otherwise, it's a few amdgpu, i915, sun4i and a panel quirk.

  amdgpu:
   - Adjust GTT size logic
   - eDP fix for RMB
   - DCN 3.15 fix
   - DP training fix
   - Color encoding fix for DCN2+

  sun4i:
   - multiple suspend fixes
