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: (23 commits) sparc: sunzilog uart order [SPARC64]: Detect trap frames in stack backtraces. [SPARC64]: %l6 trap return handling no longer necessary. [SPARC64]: Use trap type stored in pt_regs to handle syscall restart. [SPARC64]: Store magic cookie and trap type in pt_regs. [SPARC64]: PROM debug console can be CON_ANYTIME. sparc64: cleanup after SunOS/Solaris binary emulation removal sparc: cleanup after SunOS binary emulation removal [SPARC64]: Add NUMA support. [SPARC64]: Allocate TSB node-local. [SPARC64]: NUMA device infrastructure. [SPARC64]: Kill pci_iommu_table_init() declaration. [SPARC64]: Once we have the boot cmdline, call parse_early_param() [SPARC64]: Remove unused asm-sparc64/numnodes.h [SPARC64]: Decrease SECTION_SIZE_BITS to 30. [SPARC64]: Initialize MDESC earlier and use lmb_alloc() [SPARC64]: Use lmb_alloc() for PROM device tree. [SPARC64]: Call real_setup_per_cpu_areas() earlier and use lmb_alloc(). [SPARC64]: Fully use LMB information in bootmem_init(). [SPARC64]: Start using LMB information in bootmem_init(). ...
