Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
1) Fix NULL oops in Schizo PCI controller error handler.
2) Fix race between xchg and other operations on 32-bit sparc, from
Andreas Larsson.
3) swab*() helpers need a dummy memory input operand to show data flow
on 64-bit sparc.
4) Fix RCU warnings due to missing irq_{enter,exit}() around
generic_smp_call_function*() calls.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Fix constraints on swab helpers.
sparc32: Implement xchg and atomic_xchg using ATOMIC_HASH locks
sparc64: Do irq_{enter,exit}() around generic_smp_call_function*().
sparc64: Fix crashes in schizo_pcierr_intr_other().
