      Merge branch 'hot-fixes' (fixes for rc6) · 24f4b40e
      Linus Torvalds authored 
      This is a collection of three fixes for small annoyances.

Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly.  We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.

The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.

* merge 'hot-fixes' branch:
  ida: don't use BUG_ON() for debugging
  drm/aperture: Run fbdev removal before internal helpers
  ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

      ida: don't use BUG_ON() for debugging · fc82bbf4
      Linus Torvalds authored 
      This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fe: "signal handling: don't use BUG_ON() for debugging").

In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:

  "I wonder if we should even warn here -- sure, the caller is trying to
   free something that wasn't allocated, but we don't warn for
   kfree(NULL)"

and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.

This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().

The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do

    free(alloc());

even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).

Fixes: 88eca020 ("ida: simplified functions for id allocation")

      Linus Torvalds authored 
      Pull x86 fixes from Borislav Petkov:

 - Prepare for and clear .brk early in order to address XenPV guests
   failures where the hypervisor verifies page tables and uninitialized
   data in that range leads to bogus failures in those checks

 - Add any potential setup_data entries supplied at boot to the identity
   pagetable mappings to prevent kexec kernel boot failures. Usually,
   this is not a problem for the normal kernel as those mappings are
   part of the initially mapped 2M pages but if kexec gets to allocate
   the second kernel somewhere else, those setup_data entries need to be
   mapped there too.

 - Fix objtool not to discard text references from the __tracepoints
   section so that ENDBR validation still works

 - Correct the setup_data types limit as it is user-visible, before 5.19
   releases

      Masahiro Yamada authored 
      Commit 65ce9c38 ("kbuild: move module strip/compression code into
scripts/Makefile.modinst") added this unused code.

Perhaps, I thought cmd_none was useful for CONFIG_MODULE_COMPRESS_NONE,
but I did not use it after all.
