Subject[PATCH]: Remove PF_MEMDIE as it is redundant
From
Date

Hi
PF_MEMDIE don't have any use in current kernels. Please
remove, we only set it in one place, and there we also set
PF_MEMALLOC. And we only test it in other place, and we also
test for PF_MEMALLOC. This patch has existed in aa for some
quite time.

Please apply.

Later, Juan.
