Subject: Make all allocations that are allowed to fail atomic, and surpress warnings
X-Git-Tag: v4.1.12-111.0.20170907_2225~3^2~3^2~196
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=92efb6e82c11e8f241b272aab152f21bbd83d125;p=users%2Fjedix%2Flinux-maple.git

Make all allocations that are allowed to fail atomic, and surpress warnings
about out-of-memory conditions, since they are not harmful.  Also, do not allow
DTrace allocations to access the emergency pools.
