Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
1) Do serial locking in a way that makes things clear that these are
IRQ spinlocks.
2) Conversion to generic idle loop broke first generation Niagara
machines, need to have %pil interrupts enabled during cpu yield
hypervisor call.
3) Do not use magic constants for iterations over tsb tables, from Doug
Wilson.
4) Fix erroneous truncation of 64-bit system call return values to
32-bit. From Dave Kleikamp.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Make sure %pil interrupts are enabled during hypervisor yield.
sparc64:tsb.c:use array size macro rather than number
sparc64: don't treat 64-bit syscall return codes as 32-bit
sparc: serial: Clean up the locking for -rt
