Using bitfields for shared variables is a "bad idea", as they require
a non-atomic read-modify-write to be generated by the compiler, which can
cause updates to unrelated bits in the same word to disappear.
Ensure the 'online' and 'disconnected' members of 'struct acc_dev' are
placed in separate variables by declaring them each as 'int'.

Tearing down and freeing the 'acc_dev' structure when there is

If acc_setup() is called when there is already an allocated instance,
misc_register() will fail but the error path leaves a dangling pointer
to freed memory in the global 'acc_dev' state.
Fix this by ensuring that the refcount is zero before we start, and then
using a cmpxchg() from NULL to serialise any concurrent initialisers.

acc_release() attempts to synchronise with acc_open() using an atomic
'open_excl' member in 'struct acc_dev'. Unfortunately, acc_release()
prematurely resets this atomic variable to zero, meaning there is a
potential race on 'dev->disconnected':
acc_open() acc_release()
atomic_xchg(open_excl), 0)
atomic_xchg(open_excl, 1)
dev->disconnected = 0; dev->disconnected = 1;
Fix the race by ensuring that the 'disconnected' field is written
before clearing 'open_excl' in acc_release().

Merge misc updates from Andrew Morton:
- a few random little subsystems
- almost all of the MM patches which are staged ahead of linux-next
material. I'll trickle to post-linux-next work in as the dependents
get merged up.
Subsystems affected by this patch series: kthread, kbuild, ide, ntfs,
ocfs2, arch, and mm (slab-generic, slab, slub, dax, debug, pagecache,
gup, swap, shmem, memcg, pagemap, mremap, hmm, vmalloc, documentation,
kasan, pagealloc, memory-failure, hugetlb, vmscan, z3fold, compaction,
oom-kill, migration, cma, page-poison, userfaultfd, zswap, zsmalloc,
uaccess, zram, and cleanups).
