Helge Deller 5d54040e9d io_uring/parisc: Adjust pgoff in io_uring mmap() for parisc 
Vidra Jonas reported issues on parisc with libuv which then triggers
build errors with cmake. Debugging shows that those issues stem from
io_uring().

I was not able to easily pull in upstream commits directly, so here
is IMHO the least invasive manual backport of the following upstream
commits to fix the cache aliasing issues on parisc on kernel 6.1
with io_uring:

56675f8b9f ("io_uring/parisc: Adjust pgoff in io_uring mmap() for parisc")
32832a407a ("io_uring: Fix io_uring mmap() by using architecture-provided get_unmapped_area()")
d808459b2e ("io_uring: Adjust mapping wrt architecture aliasing requirements")

With this patch kernel 6.1 has all relevant mmap changes and is
identical to kernel 6.5 with regard to mmap() in io_uring.
