Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
"Several build/bug fixes for sparc, including:
1) Configuring a mix of static vs. modular sparc64 crypto modules
didn't work, remove an ill-conceived attempt to only have to build
the device match table for these drivers once to fix the problem.
Reported by Meelis Roos.
2) Make the montgomery multiple/square and mpmul instructions actually
usable in 32-bit tasks. Essentially this involves providing 32-bit
userspace with a way to use a 64-bit stack when it needs to.
3) Our sparc64 atomic backoffs don't yield cpu strands properly on
Niagara chips. Use pause instruction when available to achieve
this, otherwise use a benign instruction we know blocks the strand
for some time.
4) Wire up kcmp
5) Fix the build of various drivers by removing the unnecessary
blocking of OF_GPIO when SPARC.
6) Fix unintended regression wherein of_address_to_resource stopped
being provided. Fix from Andreas Larsson.
7) Fix NULL dereference in leon_handle_ext_irq(), also from Andreas
Larsson."
