------------------------------------------------------ From: Andrew Morton akpm@linux-foundation.org Subject: revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"
Despite Mike's attempted fix (925346c129da117122), regressions reports continue:
https://lore.kernel.org/lkml/cb5b81bd-9882-e5dc-cd22-54bdbaaefbbc@leemhuis.i... https://bugzilla.kernel.org/show_bug.cgi?id=215720 https://lkml.kernel.org/r/b685f3d0-da34-531d-1aa9-479accd3e21b@leemhuis.info
So revert this patch.
