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." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc64: Fix build with mix of modular vs. non-modular crypto drivers. sparc: Support atomic64_dec_if_positive properly. of/address: sparc: Declare of_address_to_resource() as an extern function for sparc again sparc32, leon: Check for existent irq_map entry in leon_handle_ext_irq sparc: Add sparc support for platform_get_irq() sparc: Allow OF_GPIO on sparc. qlogicpti: Fix build warning. sparc: Wire up sys_kcmp. sparc64: Improvde documentation and readability of atomic backoff code. sparc64: Use pause instruction when available. sparc64: Fix cpu strand yielding. sparc64: Make montmul/montsqr/mpmul usable in 32-bit threads.
