[PATCH 0/4] x86: Various clean-ups in support of FGKASLR

From: Kees Cook
Date: Wed Oct 13 2021 - 13:58:04 EST


Hi,

These are a small set of patches that clean up various things that are
each stand-alone improvements, but they're also needed for the coming
FGKASLR series[1]. I thought it best to just get these landed instead
of having them continue to tag along with FGKASLR, especially the
early malloc() fix, which is a foot-gun waiting to happen. :)

Thanks!
