Add task structure to vfio_dma structure. Task structure is used for:

2) Compiler-specific includes
3) acenv.h is the master file that pulls in the correct headers (one compiler,

Hi Jassi,
These patches have gone through a number of revisions now and I've
tested them to the point where I'm confident that they work well.
Given the chain of drivers that depends on this, I think it'd be good if

Coming is the patchset with the per-page spinlock as the main
modification, and two smaller dependent patches, one of which
removes build error when the z3fold header size exceeds the
size of a chunk, and the other puts non-compacted pages to the
end of the unbuddied list.

Building the Apple thunderbolt driver on non-x86 machines now produces
a harmless warning:

Most of z3fold operations are in-page, such as modifying z3fold
page header or moving z3fold objects within a page. Taking
per-pool spinlock to protect per-page objects is therefore
suboptimal, and the idea of having a per-page spinlock (or rwlock)
has been around for some time.

Currently the whole kernel build will be stopped if the size of
struct z3fold_header is greater than the size of one chunk, which
is 64 bytes by default. This may stand in the way of automated
test/debug builds so let's remove that and just fail the z3fold
initialization in such case instead.

If a z3fold page couldn't be compacted, we don't want it to be
used for next object allocation in the first place. It makes more
sense to add it to the end of the relevant unbuddied list. If that
page gets compacted later, it will be added to the beginning of
the list then.

Gcc revision 241896 implements use-after-scope detection.
Will be available in gcc 7. Support it in KASAN.
Gcc emits 2 new callbacks to poison/unpoison large stack
objects when they go in/out of scope.
Implement the callbacks and add a test.
