drm/doc: Include new drm_blend.c

There's not much point in kerneldoc if it's not included:
- It won't show up in the pretty html pages.
- The comments itself won't get parsed, which means 0day won't pick up
  changes, resulting in stale docs fast.

Also, uapi really should be core, not helpers, so move drm_blend.c to
that. That also means that the zpos normilize function loses it's
helper status (and we might as well call it always). For that,
EXPORT_SYMBOL. Just spotted while integrating docs and noticing that
one was missing.

With sphinx there's really no excuse any more to not build the docs

wait upon outstanding rendering (or just query the current status of

PM / hibernate: Restore processor state before using per-CPU variables

Restore the processor state before calling any other functions to
ensure per-CPU variables can be used with KASLR memory randomization.

Tracing functions use per-CPU variables (GS based on x86) and one was
called just before restoring the processor state fully. It resulted
in a double fault when both the tracing & the exception handler

8 years agonfsd: don't return an unhashed lock stateid after taking mutex
Jeff Layton [Thu, 11 Aug 2016 14:37:39 +0000 (10:37 -0400)]
nfsd: don't return an unhashed lock stateid after taking mutex

nfsd4_lock will take the st_mutex before working with the stateid it
gets, but between the time when we drop the cl_lock and take the mutex,
the stateid could become unhashed (a'la FREE_STATEID). If that happens
the lock stateid returned to the client will be forgotten.

Fix this by first moving the st_mutex acquisition into
lookup_or_create_lock_state. Then, have it check to see if the lock
stateid is still hashed after taking the mutex. If it's not, then put
the stateid and try the find/create again.
