Pull sparc fixes from David Miller: "Several small bug fixes and tidies, along with a fix for non-resumable memory errors triggered by userspace" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc64: Handle PIO & MEM non-resumable errors. sparc64: Zero pages on allocation for mondo and error queues. sparc: Fixed typo in sstate.c. Replaced panicing with panicking sparc: use symbolic names for tsb indexing
