The changes from commit 32832a407a71 ("io_uring: Fix io_uring mmap() by

executable when running on parisc.
This patch reverts those architecture-specific changes, and instead
adjusts in io_uring_mmu_get_unmapped_area() the pgoff offset which is
then given to parisc's get_unmapped_area() function. This is much
cleaner than the previous approach, and we still will get a coherent
addresss.

Applied, thanks!
That was fast :-)
Actually I had hoped for some more testing from Christoph and other
parisc guys first.
Anyway, since you have a parisc machine in your test ring, you will
notice if something breaks,
What's important:
Please add to the patch:
