fanotify: Fix use after free in mask checking
We cannot use the event structure returned from
fsnotify_add_notify_event() because that event can be freed by the time
that function returns. Use the mask argument passed into the event
handler directly instead. This also fixes a possible problem when we
could unnecessarily wait for permission response for a normal fanotify
event which got merged with a permission event.
We also disallow merging of permission event with any other event so
that we know the permission event which we just created is the one on
which we should wait for permission response.

ceph: Fix up after semantic merge conflict
The previous ceph-client merge resulted in ceph not even building,
because there was a merge conflict that wasn't visible as an actual data
conflict: commit 7221fe4c2ed7 ("ceph: add acl for cephfs") added support
for POSIX ACL's into Ceph, but unluckily we also had the VFS tree change
a lot of the POSIX ACL helper functions to be much more helpful to
filesystems (see for example commits 2aeccbe957d0 "fs: add generic
xattr_acl handlers", 5bf3258fd2ac "fs: make posix_acl_chmod more useful"
and 37bc15392a23 "fs: make posix_acl_create more useful")
The reason this conflict wasn't obvious was many-fold: because it was a
semantic conflict rather than a data conflict, it wasn't visible in the
git merge as a conflict. And because the VFS tree hadn't been in
linux-next, people hadn't become aware of it that way. And because I
was at jury duty this morning, I was using my laptop and as a result not
doing constant "allmodconfig" builds.
Anyway, this fixes the build and generally removes a fair chunk of the
Ceph POSIX ACL support code, since the improved helpers seem to match
really well for Ceph too. But I don't actually have any way to *test*
the end result, and I was really hoping for some ACK's for this. Oh,
well.
Not compiling certainly doesn't make things easier to test, so I'm
committing this without the acks after having waited for four hours...
Plus it's what I would have done for the merge had I noticed the
semantic conflict..

mtd: gpmi: allocate a proper buffer for non ECC read/write
The @data_buffer_dma buffer is used for non ECC read/write.
Currently, the length of the buffer is PAGE_SIZE, but the NAND chip may
has 8K page or 16K page. So we have to extend it for the large page NAND
chips.
The gpmi_alloc_dma_buffer will be called twice. The first time is to
allocate a temporary buffer for scanning the NAND chip; The second time
is to allocate a buffer to store the real page content.
This patch allocates a buffer of PAGE_SIZE size for scanning the NAND
chip when gpmi_alloc_dma_buffer is called the first time, and allocates a
buffer of the real NAND page size for the second time gpmi_alloc_dma_buffer
is called.
