that breakage has been reported independently as well and the revert has
been pushed to Linus yesterday - it's not upstream yet. See this commit
in x86.git:
commit 1b8104a0ec138de829bb351f6597d534c7c134dc

revert: "x86: ioremap(), extend check to all RAM pages"
Vegard Nossum reported a large (150 seconds) boot delay during bootup,
and bisected it to "x86: ioremap(), extend check to all RAM pages"
(commit bdd3cee2e4b). Revert this commit for now.
