Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6: math-emu: correct test for downshifting fraction in _FP_FROM_INT() perf: Add DWARF register lookup for sparc MAINTAINERS: Add SBUS driver path to sparc entry. drivers/sbus: Remove unnecessary casts of private_data sparc: remove homegrown L1_CACHE_ALIGN macro sparc64: fix the build error due to smp_kgdb_capture_client() sparc64: Fix maybe_change_configuration() PCR setting. arch/sparc/kernel: Eliminate what looks like a NULL pointer dereference sparc64: Update defconfig. sunsu: Fix use after free in su_remove(). sunserial: Don't call add_preferred_console() when console= is specified. sparc32: Kill none_mask, it's bogus.
