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().
