928c2f0c00 drm/fb-helper: don't sleep for screen unblank when an oops is in progress
Otherwise the system will burn even brighter and worse, leave the user
wondering what's going on exactly.

Since we already have a panic handler which will (try) to restore the
entire fbdev console mode, we can just bail out.  Inspired by a patch from
Konstantin Khlebnikov.  The callchain leading to this, cut&pasted from
Konstantin's original patch:

callstack:
panic()
bust_spinlocks(1)
unblank_screen()
vc->vc_sw->con_blank()
fbcon_blank()
fb_blank()
info->fbops->fb_blank()
drm_fb_helper_blank()
drm_fb_helper_dpms()
drm_modeset_lock_all()
mutex_lock(&dev->mode_config.mutex)

Note that the entire locking in the fb helper around panic/sysrq and kdbg
is ...  non-existant.  So we have a decent change of blowing up
everything.  But since reworking this ties in with funny concepts like the
fbdev notifier chain or the impressive things which happen around
console_lock while oopsing, I'll leave that as an exercise for braver
souls than me.

182b17c8dc drm/ttm: fix the tt_populated check in ttm_tt_destroy()
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.

On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer.  After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.

It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.

9baa505948 Three pstore fixes related to compression:
1) Better adjustment of size of compression buffer (was too big
    for EFIVARS backend resulting in compression failure
 2) Use zlib_inflateInit2 instead of zlib_inflateInit
 3) Don't print messages about compression failure.  They will
    waste space that may better be used to log console output
    leading to the crash.

03e1261778 tty: disassociate_ctty() sends the extra SIGCONT
Starting from v3.10 (probably commit f91e259041: "tty: Signal
foreground group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit.  This breaks LSB test-suite, in particular test8 in
_exit.c and test40 in sigcon5.c.

Put the "!on_exit" check back to restore the old behaviour.

Review by Peter Hurley:
 "Yes, this regression was introduced by me in that commit.  The effect
  of the regression is that ptys will receive a SIGCONT when, in similar
  circumstances, ttys would not.

  The fact that two test vectors accidentally tripped over this
  regression suggests that some other apps may as well.

  Thanks for catching this"

ba6a354154 KVM: mmu: allow page tables to be in read-only slots
Page tables in a read-only memory slot will currently cause a triple
fault because the page walker uses gfn_to_hva and it fails on such a slot.

OVMF uses such a page table; however, real hardware seems to be fine with
that as long as the accessed/dirty bits are set.  Save whether the slot
is readonly, and later check it when updating the accessed and dirty bits.

116cc02253 vfs: don't set FILE_CREATED before calling ->atomic_open()
If O_CREAT|O_EXCL are passed to open, then we know that either

 - the file is successfully created, or
 - the operation fails in some way.

So previously we set FILE_CREATED before calling ->atomic_open() so the
filesystem doesn't have to.  This, however, led to bugs in the
implementation that went unnoticed when the filesystem didn't check for
existence, yet returned success.  To prevent this kind of bug, require
filesystems to always explicitly set FILE_CREATED on O_CREAT|O_EXCL and
verify this in the VFS.

Also added a couple more verifications for the result of atomic_open():

 - Warn if filesystem set FILE_CREATED despite the lack of O_CREAT.
 - Warn if filesystem set FILE_CREATED but gave a negative dentry.

7de8fe2fa8 pstore: Adjust buffer size for compression for smaller registered buffers
When backends (ex: efivars) have smaller registered buffers, the
big_oops_buf is too big for them as number of repeated occurences
in the text captured will be less. What happens is that pstore takes
too big a bite from the dmesg log and then finds it cannot compress it
enough to meet the backend block size. Patch takes care of adjusting
the buffer size based on the registered buffer size. cmpr values have
been arrived after doing experiments with plain text for buffers of
size 1k - 4k (Smaller the buffer size repeated occurence will be less)
and with sample crash log for buffers ranging from 4k - 10k.
