[PATCH 0/2] io_uring: Fix io_uring mmap() by using architecture-provided get_unmapped_area()

From: Helge Deller
Date: Fri Jul 21 2023 - 11:24:50 EST


Fix io_uring on IA64 (and x86-32?) which was broken since commit
d808459b2e31 ("io_uring: Adjust mapping wrt architecture aliasing
requirements").
The fix is to switch back to the get_unmapped_area() which is provided by
each architecture.

Patch 1 switches io_uring back to use per-arch get_unmapped_area().
Patch 2 (for IA64) is an independend cleanup.
