Subject: HWPOISON: Turn addr_valid from bitfield into char
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9033ae16407f46ae06f559f9374281f6e9d89efc;p=deliverable%2Flinux.git

HWPOISON: Turn addr_valid from bitfield into char

The addr_valid flag is the only flag in "to_kill" and it's slightly more
efficient to have it as char instead of a bitfield.
