Subject: ARM: pgd allocation: retry on failure
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8c65da6dc89ccb605d73773b1dd617e72982d971;p=deliverable%2Flinux.git

ARM: pgd allocation: retry on failure

Make pgd allocation retry on failure; we really need this to succeed
otherwise fork() can trigger OOMs.
