Subject: [GIT PULL] (swiotlb) stable/for-linus-5.12

Hey Linus,

Please git pull the following branch:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-5.12

which has two memory encryption related patches (SWIOTLB is enabled by
default for AMD-SEV):

 1) Adding support for alignment so that NVME can properly work,
 2) Keep track of requested DMA buffers length, as underlaying hardware devices
    can trip SWIOTLB to bounce too much and crash the kernel.

And a tiny fix to use proper APIs in drivers.

Please note you will see the tree a bit fresh - that is due to me squashing
in a fix earlier this week, which caused a conflict later, and me fixing up
the conflict caused the authorship to shift to me which I just fixed up now.

Argh!
