commit 9cb636b5f6 upstream.
A race condition may occur if the user calls close() on another thread
during a write() operation on the device node of the efi capsule.
This is a race condition that occurs between the efi_capsule_write() and
efi_capsule_flush() functions of efi_capsule_fops, which ultimately
results in UAF.
So, the page freeing process is modified to be done in
efi_capsule_release() instead of efi_capsule_flush().

It is cleaner to set lease key to zero in the places where leases are not
supported (smb1 can not return lease keys so the field was uninitialized).

Cortex-A510 erratum 2454944 may cause clean cache lines to be
erroneously written back to memory, breaking the assumptions we rely on
for non-coherent DMA. Try to mitigate this by implementing special DMA
ops that do their best to avoid cacheable aliases via a combination of
bounce-buffering and manipulating the linear map directly, to minimise
the chance of DMA-mapped pages being speculated back into caches.
The other main concern is initial entry, where cache lines covering the
kernel image might potentially become affected between being cleaned by
the bootloader and the kernel being called, so perform some additional
maintenance to be safe in that regard too. Cortex-A510 supports S2FWB,
so KVM should be unaffected.

Add an interface for arch code to disable lazy vunmap by forcing the
threshold to zero. This might be interesting for debugging/testing in
general, but primarily helps a horrible situation which needs to
guarantee that vmalloc aliases are up-to-date from atomic context,
wherein the only practical solution is to never let them get stale in
the first place.
