SubjectRe: [bkpatch] do_mmap cleanup
Hi!

> Below is a vm cleanup that can be pulled from bk://bcrlbits.bk.net/vm-2.5 .
> The bulk of the patch is moving the down/up_write on mmap_sem into do_mmap
> and removing that from all the callers. The patch also includes a fix for
> do_mmap which caused mapping of the last page in the address space to fail.

Was not that a workaround for CPU bugs?
