Subject: mm: remove the might_sleep() from lock_page()
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Arjan reports that hwclock(8) likes to run pagefaults with local
interrupts disabled (via sys_iopl()), which causes scary warnings and
traces.
It's a bug in hwclock, but let's not worry people and create additional
bug reports.
(Also, adding a migt_sleep() to the inlined, 600-call-site lock_page()
wasn't a great idea. A might_sleep() is pretty large.)
