Merge tag 'for-linus' of git://github.com/openrisc/linux
Pull OpenRISC updates from Stafford Horne: "A few patches all over the place during this cycle, mostly bug and sparse warning fixes for OpenRISC, but a few enhancements too. Note, there are 2 non OpenRISC specific fixups. Non OpenRISC fixes: - In init we need to align the init_task correctly to fix an issue with MUTEX_FLAGS, reviewed by Peter Z. No one picked this up so I kept it on my tree. - In asm-generic/io.h I fixed up some sparse warnings, OK'd by Arnd. Arnd asked to merge it via my tree. OpenRISC fixes: - Many fixes for OpenRISC sprase warnings. - Add support OpenRISC SMP tlb flushing rather than always flushing the entire TLB on every CPU. - Fix bug when dumping stack via /proc/xxx/stack of user threads" * tag 'for-linus' of git://github.com/openrisc/linux: openrisc: uaccess: Add user address space check to access_ok openrisc: signal: Fix sparse address space warnings openrisc: uaccess: Remove unused macro __addr_ok openrisc: uaccess: Use static inline function in access_ok openrisc: uaccess: Fix sparse address space warnings openrisc: io: Fixup defines and move include to the end asm-generic/io.h: Fix sparse warnings on big-endian architectures openrisc: Implement proper SMP tlb flushing openrisc: Fix oops caused when dumping stack openrisc: Add support for external initrd images init: Align init_task to avoid conflict with MUTEX_FLAGS openrisc: fix __user in raw_copy_to_user()'s prototype
