Subject: [GIT PULL] (swiotlb) for-linus-5.3

Hey Linus,

I've sent you a prior git pull which contained two of the fixes, and this
one expands on the one from Juergen which had been committed a while ago
but hadn't been fully tested until during the merge window so I delayed
until now.

Please git pull the following branch:

git push gitolite@...kernel.org:/pub/scm/linux/kernel/git/konrad/swiotlb.git for/linus-5.3

which contains fixes for properly determining if the SWIOTLB is actually enabled on ARM
platforms, compiler fixes, and corruption fix when used with Xen where
we would have inconsistent mappings of multiple PFNs to the same MFN when
destroying long setup DMA buffers.

If you already have pulled 'for-linus-5.2' your git diff stat will be a bit
different.
