Subject: [PATCH 0/3] binfmt_elf: Honor PT_LOAD alignment for static PIE

Hi,

This attempts to implement PT_LOAD p_align support for static PIE builds.
I intend this to go into -next after the coming merge window so we can
maximize bake time. In the past we've had regressions with both the
selftests and the ELF loader. Hopefully we can shake everything out over
a few months. :)

Thanks!

-Kees
