Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
"A small bunch of bug fixes, in particular:
1) On older cpus we need a different chunk of virtual address space
to map the huge page TSB.
2) Missing memory barrier in Niagara2 memcpy.
3) trinity showed some places where fault validation was
unnecessarily loud on sparc64
4) Some sysfs printf's need a type adjustment, from Toralf Förster"
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: fix format string mismatch in arch/sparc/kernel/sysfs.c
sparc64: Add membar to Niagara2 memcpy code.
sparc64: Fix huge TSB mapping on pre-UltraSPARC-III cpus.
sparc64: Don't bark so loudly about 32-bit tasks generating 64-bit fault addresses.
