------------------------------------------------------ From: Andrew Morton akpm@linux-foundation.org Subject: revert "fs/binfmt_elf: fix PT_LOAD p_align values for loaders"
925346c129da11 ("fs/binfmt_elf: fix PT_LOAD p_align values for loaders") is an attempt to fix regressions due to 9630f0d60fec5f ("fs/binfmt_elf: use PT_LOAD p_align values for static PIE").
But regressionss continue to be reported:
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
This patch reverts the fix, so the original can also be reverted.
