Allow PF_MEMALLOC to be set in softirq context. When running softirqs from

What's this for? Why would ksoftirqd pick up PF_MEMALLOC? (I guess
that some networking thing must be picking it up in a subsequent patch,
but I'm too lazy to look!)... Again, can you have more of a rationale in
your patch headers, or ref the patch that uses it... thanks
