Subject: kmemcheck: remove useless check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=414f3251aa1b4cbd1e070866971eabc004a7dc20;p=linux.git

kmemcheck: remove useless check

This check is a left-over from ancient times. We now have the equivalent
check much earlier in both the page fault handler and the debug trap
handler (the calls to kmemcheck_active()).
