Subject[GIT PULL] usercopy fix for v5.4-rc1
Hi Linus,

Please pull this usercopy fix for v5.4-rc1. Randy found a corner case
(HIGHMEM, DEBUG_VIRTUAL, >512MB RAM) with hardened usercopy that went
unnoticed since v4.8. This adds HIGHMEM awareness to hardened usercopy,
and has been living in -next for a bit more than a week now.



The following changes since commit 4d856f72c10ecb060868ed10ff1b1453943fc6c8:
