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: sparc64: Fix clock event multiplier printf format. sparc64: Use clock{source,events}_calc_mult_shift(). sparc64: Use free_bootmem_late() in mdesc_lmb_free(). sparc: Add alignment and emulation fault perf events. sparc64: Add syscall tracepoint support. sparc: Stop trying to be so fancy and use __builtin_{memcpy,memset}() sparc: Use __builtin_object_size() to validate the buffer size for copy_from_user() sparc64: Add some missing __kprobes annotations to kernel fault paths. sparc64: Use kprobes_built_in() to avoid ifdefs in fault_64.c sparc: Validate that kprobe address is 4-byte aligned. sparc64: Don't specify IRQF_SHARED for LDC interrupts. sparc64: Fix stack debugging IRQ stack regression. sparc64: Fix overly strict range type matching for PCI devices.
