         * allowed for hubs during binding.

        usb_disable_autosuspend(udev);

So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.

This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.

This reverts commit 7bd9fb05.

Pull close_range() fix from Christian Brauner:
 "Syzbot reported a bug in close_range.

  Debugging this showed we didn't recalculate the current maximum fd
  number for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC after we unshared
  the file descriptors table. As a result, max_fd could exceed the
  current fdtable maximum causing us to set excessive bits.

  As a concrete example, let's say the user requested everything from fd
  4 to ~0UL to be closed and their current fdtable size is 256 with
  their highest open fd being 4. With CLOSE_RANGE_UNSHARE the caller
  will end up with a new fdtable which has room for 64 file descriptors
  since that is the lowest fdtable size we accept. But now max_fd will
  still point to 255 and needs to be adjusted. Fix this by retrieving
  the correct maximum fd value in __range_cloexec().

  I've carried this fix for a little while but since there was no
  linux-next release over easter I waited until now.

  With this change close_range() can be further simplified but imho we
  are in no hurry to do that and so I'll defer this for the 5.13 merge
  window"

Pull umount fix from Al Viro:
 "Brown paperbag time: dumb braino in the series that went into 5.7
  broke the 'don't step into ->d_weak_revalidate() when umount(2) looks
  the victim up' behaviour.

  Spotted only now - saw

        if (!err && unlikely(nd->flags & LOOKUP_MOUNTPOINT)) {
                err = handle_lookup_down(nd);
                nd->flags &= ~LOOKUP_JUMPED; // no d_weak_revalidate(), please...
        }

  and went "why do we clear that flag here - nothing below that point is
  going to check it anyway" / "wait a minute, what is it doing *after*
  complete_walk() (which is where we check that flag and call
  ->d_weak_revalidate())" / "how could that possibly _not_ break?",
  followed by reproducing the breakage and verifying that the obvious
  fix of that braino does, indeed, fix it.

  The reproducer is (assuming that $DIR exists and is exported r/w to
  localhost)

      mkdir $DIR/a
      mkdir /tmp/foo
      mount --bind /tmp/foo /tmp/foo
      mkdir /tmp/foo/a
      mkdir /tmp/foo/b
      mount -t nfs4 localhost:$DIR/a /tmp/foo/a
      mount -t nfs4 localhost:$DIR /tmp/foo/b
      rmdir /tmp/foo/b/a
      umount /tmp/foo/b
      umount /tmp/foo/a
      umount -l /tmp/foo      # will get everything under /tmp/foo, no matter what

  Correct behaviour is successful umount; broken kernels (5.7-rc1 and
  later) get

      umount.nfs4: /tmp/foo/a: Stale file handle

  Note that bind mount is there to be able to recover - on broken
  kernels we'd get stuck with impossible-to-umount filesystem if not for
  that.

  FWIW, that braino had been posted for review back then, at least
  twice. Unfortunately, the call of complete_walk() was outside of diff
  context, so the bogosity hadn't been immediately obvious from the
  patch alone ;-/"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  LOOKUP_MOUNTPOINT: we are cleaning "jumped" flag too late

Right now, if a call to kvm_tdp_mmu_zap_sp returns false, the caller
will skip the TLB flush, which is wrong.  There are two ways to fix
it:

- since kvm_tdp_mmu_zap_sp will not yield and therefore will not flush
  the TLB itself, we could change the call to kvm_tdp_mmu_zap_sp to
  use "flush |= ..."

- or we can chain the flush argument through kvm_tdp_mmu_zap_sp down
  to __kvm_tdp_mmu_zap_gfn_range.  Note that kvm_tdp_mmu_zap_sp will
  neither yield nor flush, so flush would never go from true to
  false.

This patch does the former to simplify application to stable kernels,
and to make it further clearer that kvm_tdp_mmu_zap_sp will not flush.

This patch adds the specific quirk for the device to restore the COEF

Fix this issue by moving the initialization of dd->node to hfi1_devdata

wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead()
into acpi_idle_play_dead(). The problem is that these functions are not
exported to modules so when CONFIG_ACPI_PROCESSOR=m build fails.

The issue could've been fixed by exporting both wakeup_cpu0()/start_cpu0()

ASoC: Fixes for v5.12

A fairly small batch of driver specific fixes, mainly for various x86
systems with the biggest set being fixes to power down DSPs properly on
x86 SOF systems.

Use memblock_free_late() to free the old machine check stack to the
buddy allocator instead of leaking it.

Some devices send (duplicate) tablet-mode events when moved around even
though the mode has not changed; and they do this even when suspended.

Change the tablet-mode event handling when priv->wakeup_mode is set to
update the switch state in case it changed and then return immediately
(without calling pm_wakeup_hard_event()) to avoid spurious wakeups.

Pull fs fixes from Al Viro:
 "Fairly old hostfs bug (in setups that are not used by anyone,
  apparently) + fix for this cycle regression: extra dput/mntput in
  LOOKUP_CACHED failure handling"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  Make sure nd->path.mnt and nd->path.dentry are always valid pointers
  hostfs: fix memory handling in follow_link()

Initialize them in set_nameidata() and make sure that terminate_walk() clears them
once the pointers become potentially invalid (i.e. we leave RCU mode or drop them
in non-RCU one).  Currently we have "path_init() always initializes them and nobody
accesses them outside of path_init()/terminate_walk() segments", which is asking
for trouble.

With that change we would have nd->path.{mnt,dentry}
	1) always valid - NULL or pointing to currently allocated objects.
	2) non-NULL while we are successfully walking
	3) NULL when we are not walking at all
	4) contributing to refcounts whenever non-NULL outside of RCU mode.

commit b344d6a8 ("parisc: add support for cmpxchg on u8 pointers")
can generate a sparse warning ("cast truncates bits from constant
value"), which has been reported several times [1] [2] [3].

The original code worked as expected, but anyway, let silence such
sparse warning as what others did [4].
