The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.

Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.

And the code really does depend on stack layout that is only true in the
simplest of cases.  We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:

	Assume the lock function has either no stack frame or a copy
	of eflags from PUSHF.

which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:

	Eflags always has bits 22 and up cleared unlike kernel addresses

but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.

It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].

With no real practical reason for this any more, just remove the code.

Just for historical interest, here's some background commits relating to
this code from 2006:

  0cb91a22 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
  31679f38 ("Simplify profile_pc on x86-64")

and a code unification from 2009:

  ef451288 ("x86: time_32/64.c unify profile_pc")

but the basics of this thing actually goes back to before the git tree.

STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

 "Simple stuff:

   - NULL ptr/err ptr deref fixes

   - fix for getting wedged on shutdown after journal error

   - fix missing recalc_capacity() call, capacity now changes correctly
     after a device goes read only

     however: our capacity calculation still doesn't take into account
     when we have mixed ro/rw devices and the ro devices have data on
     them, that's going to be a more involved fix to separate accounting
     for "capacity used on ro devices" and "capacity used on rw devices"

   - boring syzbot stuff

  Slightly more involved:

   - discard, invalidate workers are now per device

     this has the effect of simplifying how we take device refs in these
     paths, and the device ref cleanup fixes a longstanding race between
     the device removal path and the discard path

   - fixes for how the debugfs code takes refs on btree_trans objects we
     have debugfs code that prints in use btree_trans objects.

     It uses closure_get() on trans->ref, which is mainly for the cycle
     detector, but the debugfs code was using it on a closure that may
     have hit 0, which is not allowed; for performance reasons we cannot
     avoid having not-in-use transactions on the global list.

Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:

  struct foo {
    int count;
    char buf[];
  };

  struct bar {
    int count;
    struct foo data[] __counted_by(count);
  };

because the size of data cannot be calculated with the standard array
size formula:

  sizeof(struct foo) * count

This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the
ports member of 'struct mxser_board' triggers this restriction,
resulting in:

  drivers/tty/mxser.c:291:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct mxser_port' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
    291 |         struct mxser_port ports[] __counted_by(nports);
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~
  1 error generated.

Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

An unintended consequence of commit 9c573cd3 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.

The prior intent of the per-architecture limits were:

  arm64: capped at 0x1FF (9 bits), 5 bits effective
  powerpc: uncapped (10 bits), 6 or 7 bits effective
  riscv: uncapped (10 bits), 6 bits effective
  x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
  s390: capped at 0xFF (8 bits), undocumented effective entropy

Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

Commit 78464d76 ("tools/power turbostat: Add columns for clustered
uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()'
in a way which prevents printing uncore frequency columns if either of
the '-q' or '-l' options are used. Systems which do not have multiple
uncore frequencies per package are unaffected by this regression.

Fix the function so that uncore frequency columns are shown when either
the '-l' or '-q' option is used by checking if 'quiet' is true after
adding counters for the uncore frequency columns.

In some cases specifying the '-n' command line argument will cause
turbostat to fail.  For instance 'turbostat -n 1' works fine; however,
'turbostat -n 1 -d' will fail.  This is the result of the first call
to getopt_long_only() where "MP" is specified as the optstring.  This can
be easily fixed by changing the optstring from "MP" to "MPn:" to remove
ambiguity between the arguments.

 "Regular fixes, mostly amdgpu with some minor fixes in other places,
  along with a fix for a very narrow UAF race in the pid handover code.

  core:
   - fix refcounting race on pid handover

  fbdev:
   - Fix fb_info when vmalloc is used, regression from
     CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM.

  amdgpu:
   - SMU 14.x fix
   - vram info parsing fix
   - mode1 reset fix
   - LTTPR fix
   - Virtual display fix
   - Avoid spurious error in PSP init

  i915:
   - Fix potential UAF due to race on fence register revocation

  nouveau
   - nouveau tv mode fixes

  panel:
   - Add KOE TX26D202VM0BWA timings"

filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:

process A               process B
=========               =========
                        begin drm_file_update_pid
                        mutex_lock(&dev->filelist_mutex)
                        rcu_replace_pointer(filp->pid, <pid B>, 1)
                        mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>)   *** pid B reaches refcount 0 and is freed here ***
                        get_pid(<pid B>)   *** UAF ***
                        synchronize_rcu()
                        put_pid(<pid A>)

As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.

This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().

Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.

This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.
