[GIT PULL] x86 cleanups for v5.7

[Ingo Molnar]

Linus,

Please pull the latest x86-cleanups-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cleanups-for-linus

   # HEAD: a2150327250efa866c412caee84aaf05ebff9a8f Merge branch 'next.uaccess-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs into x86/cleanups

This topic tree contains more commits than usual:

 - most of it are uaccess cleanups/reorganization by Al

 - there's a bunch of prototype declaration (--Wmissing-prototypes) cleanups

 - misc other cleanups all around the map.
