The GPF / page fault messages I get from 2.4 actually all turn
out to be harmless.
The page fault messages come from a get_user in
map_ldt_shadow_page, and the GPF messages come when pop'ing an
old gs value during a multicall. They're very occasional and
aren't anything to worry about -- just the sign of a slow path
being invoked due to something slightly unusual happening.
