So set the coherent dma mask accordingly. This dma mask is only used

Now this never really surfaced because sane 32bit kernels only have 1G
of lowmem. But some eager testers (distros?) still carry around the patch
to adjust lowmem via a kconfig option. And the kernel seems to favour
high allocations on boot-up, hence the overlay blowing up reliably.
Because the patch is tiny and nicely shows how broken gen2 is it's imho
worth to merge despite the fact that mucking around with the lowmem/
highmem division is (no longer) supported.

Now that the driver for the Blackfin on-chip NFC no longer uses/respects

since the defines no longer exists.

impossible to lookup existing encrypted file names and any newly created

nfsd4: fix downgrade/lock logic
If we already had a RW open for a file, and get a readonly open, we were
piggybacking on the existing RW open. That's inconsistent with the
downgrade logic which blows away the RW open assuming you'll still have
a readonly open.
Also, make sure there is a readonly or writeonly open available for
locking, again to prevent bad behavior in downgrade cases when any RW
open may be lost.

Looks like the commit 0b8f18e3 assumed that cifs_get_inode_info() and
friends fail only due to memory allocation error when the inode is NULL
which is not the case if CIFSSMBQPathInfo() fails and returns an error.
Fix this by propagating the actual error code back.
