/proc/kallsyms and /proc/modules are compared before and after the copy
in order to ensure no changes during the copy.

However /proc/modules also might change due to reference counts changing
even though that does not make any difference.

Any modules loaded or unloaded should be visible in changes to kallsyms,
so it is not necessary to check /proc/modules also anyway.

Remove the comparison checking that /proc/modules is unchanged.

Originally, (refer commit f90d194a ("perf evlist: Do not poll
events that use the system_wide flag") there wasn't much reason to poll
system-wide events because:

 1. The mmaps get "merged" via set-output anyway (the per-cpu case)
 2. perf reads all mmaps when any event is woken
 3. system-wide mmaps do not fill up as fast as the mmaps for user
    selected events

But there was 1 reason not to poll which was that it prevented correct
termination due to POLLHUP on all user selected events.  That issue is
now easily resolved by using fdarray_flag__nonfilterable.

With the advent of commit ae4f8ae1 ("libperf evlist: Allow
mixing per-thread and per-cpu mmaps"), system-wide mmaps can be used
also in the per-thread case where reason 1 does not apply.

Fix the omission of system-wide events from polling by using the
fdarray_flag__nonfilterable flag.

Example:

 Before:

    $ perf record --no-bpf-event -vvv -e intel_pt// --per-thread uname 2>err.txt

With mixed per-thread and (system-wide) per-cpu maps, the "any cpu" value
 -1 must be skipped when setting CPU mask bits.

Prior to commit cbd7bfc7 ("tools/perf: Fix out of bound access
to cpu mask array") the invalid setting went unnoticed, but since then
it causes perf record to fail with an error.

Example:

 Before:

   $ perf record -e intel_pt// --per-thread uname
   Failed to initialize parallel data streaming masks

 After:

   $ perf record -e intel_pt// --per-thread uname

If it mixes core and uncore events, each evsel would have different cpu map.
But it assumed they are same with evlist's all_cpus and accessed by the same

It seems the recent libbpf got more strict about the section name.
I'm seeing a failure like this:

  $ sudo ./perf stat -a --bpf-counters --for-each-cgroup ^. sleep 1
  libbpf: prog 'on_cgrp_switch': missing BPF prog type, check ELF section name 'perf_events'

  libbpf: failed to load object 'bperf_cgroup_bpf'
  libbpf: failed to load BPF skeleton 'bperf_cgroup_bpf': -22
  Failed to load cgroup skeleton

The section name should be 'perf_event' (without the trailing 's').
Although it's related to the libbpf change, it'd be better fix the
section name in the first place.

Pull vfs fix from Christian Brauner:
 "Beginning of the merge window we introduced the vfs{g,u}id_t types in
  b27c82e1 ("attr: port attribute changes to new types") and changed
  various codepaths over including chown_common().

  When userspace passes -1 for an ownership change the ownership fields
  in struct iattr stay uninitialized. Usually this is fine because any
  code making use of any fields in struct iattr must check the
  ->ia_valid field whether the value of interest has been initialized.
  That's true for all struct iattr passing code.

  However, over the course of the last year with more heavy use of KMSAN
  we found quite a few places that got this wrong. A recent one I fixed
  was 3cb6ee99 ("9p: only copy valid iattrs in 9P2000.L setattr
  implementation").

  But we also have LSM hooks. Actually we have two. The first one is
  security_inode_setattr() in notify_change() which does the right thing
  and passes the full struct iattr down to LSMs and thus LSMs can check
  whether it is initialized.

  But then we also have security_path_chown() which passes down a path
  argument and the target ownership as the filesystem would see it. For
  the latter we now generate the target values based on struct iattr and
  pass it down. However, when userspace passes -1 then struct iattr
  isn't initialized.

  This patch simply initializes ->ia_vfs{g,u}id with INVALID_VFS{G,U}ID
  so the hook continue to see invalid ownership when -1 is passed from
  userspace. The only LSM that cares about the actual values is Tomoyo.

  The vfs codepaths don't look at these fields without ->ia_valid being
  set so there's no harm in initializing ->ia_vfs{g,u}id. Arguably this
  is also safer since we can't end up copying valid ownership values
  when invalid ownership values should be passed.

  This only affects mainline. No kernel has been released with this and
  thus no backport is needed. The commit is thus marked with a Fixes:
  tag but annotated with "# mainline only" (I didn't quite remember what
  Greg said about how to tell stable autoselect to not bother with fixes

Beginning of the merge window we introduced the vfs{g,u}id_t types in
b27c82e1 ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().

During that change we forgot to account for the case were the passed
ownership value is -1. In this case the ownership fields in struct iattr
aren't initialized but we rely on them being initialized by the time we
generate the ownership to pass down to the LSMs. All the major LSMs
don't care about the ownership values at all. Only Tomoyo uses them and
so it took a while for syzbot to unearth this issue.

Fix this by initializing the ownership fields and do it within the
retry_deleg block. While notify_change() doesn't alter the ownership
fields currently we shouldn't rely on it.

Since no kernel has been released with these changes this does not
needed to be backported to any stable kernels.

There's a bug in blkdev_issue_secure_erase. The statement
"unsigned int len = min_t(sector_t, nr_sects, max_sectors);"
sets the variable "len" to the length in sectors, but the statement
"bio->bi_iter.bi_size = len" treats it as if it were in bytes.
The statements "sector += len << SECTOR_SHIFT" and "nr_sects -= len <<
SECTOR_SHIFT" are thinko.

This patch fixes it.

The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.

This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
    ARCH=parisc     -> build 32-bit kernel
    ARCH=parisc64   -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).

The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

Move common IP init before GMC init so that HDP gets
remapped before GMC init which uses it.

This fixes the Unsupported Request error reported through
AER during driver load. The error happens as a write happens
to the remap offset before real remapping is done.

The error was unnoticed before and got visible because of the commit

This mirrors what we do for other asics and this way we are
sure the sdma doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  However, the statement says that it applies to
multimedia as well, but the VCN code currently initializes
doorbells after GFX and there are no known issues there.  In my
testing at least I don't see any problems on SDMA.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

When an external device generated a level based interrupt then the
interrupt controller could miss the interrupt. The reason is that the
interrupt controller can detect only link changes.

In the following example, if there is a PHY that generates an interrupt
then the following would happen. The GPIO detected that the interrupt
line changed, and then the 'ocelot_irq_handler' was called. Here it
detects which GPIO line saw the change and for that will call the
following:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

And this works fine for simple cases, but if the PHY generates many
interrupts, for example when doing PTP timestamping, then the following
could happen. Again the function 'ocelot_irq_handler' will be called
and then from here the following could happen:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask

Right before step 3(irq_eoi), the PHY will generate another interrupt.
Now the interrupt controller will acknowledge the change in the
interrupt line. So we miss the interrupt.

A solution will be to use 'handle_level_irq' instead of
'handle_fasteoi_irq', because for this will change routine order of
handling the interrupt.
1. irq_mask
2. irq_ack
3. phy interrupt routine
4. irq_unmask

And now if the PHY will generate a new interrupt before irq_unmask, the
interrupt controller will detect this because it already acknowledge the
change in interrupt line at step 2(irq_ack).

But this is not the full solution because there is another issue. In
case there are 2 PHYs that share the interrupt line. For example phy1
generates an interrupt, then the following can happen:
1.irq_mask
2.irq_ack
3.phy0 interrupt routine
4.phy1 interrupt routine
5.irq_unmask

In case phy0 will generate an interrupt while clearing the interrupt
source in phy1, then the interrupt line will be kept down by phy0. So
the interrupt controller will not see any changes in the interrupt line.
The solution here is to update 'irq_unmask' such that it can detect if
the interrupt line is still active or not. And if it is active then call
again the procedure to clear the interrupts. But we don't want to do it
every time, only if we know that the interrupt controller has not seen
already that the interrupt line has changed.

While at this, add support also for IRQ_TYPE_LEVEL_LOW.

Commit 6c846d02 ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips.  Following this change the following warnings
are now observed for the mt7621 driver:

gpio gpiochip0: (1e000600.gpio-bank0): not an immutable chip, please consider fixing it!
gpio gpiochip1: (1e000600.gpio-bank1): not an immutable chip, please consider fixing it!
gpio gpiochip2: (1e000600.gpio-bank2): not an immutable chip, please consider fixing it!

Fix this by making the irqchip in the mt7621 driver immutable.
