Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
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
