Hi Peter,
This patchset looks pretty nice to me.

One minor nit:
Peter Zijlstra wrote:
In light of the recent pagefault and filemap_copy_from_user work I've
gone through all the arch pagefault handlers to make sure the
inc_preempt_count() 'feature' works as expected.
Several sections of code (including the new filemap_copy_from_user) rely
on the fact that faults do not take locks under increased preempt count.
arch/x86_64 - good
arch/powerpc - good
arch/cris - fixed
arch/i386 - good
arch/parisc - fixed
arch/sh - good
arch/sparc - good
arch/s390 - good
arch/m68k - fixed
arch/ppc - good
arch/alpha - fixed
arch/mips - good
arch/sparc64 - good
arch/ia64 - good
arch/arm - fixed
arch/um - NA
um does have a fault handler (in kernel/trap.c), but it gets the
in_atomic check correct.
Thanks for doing this.
Nick
