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
