Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: (230 commits) [SPARC64]: Update defconfig. [SPARC64]: Fix 2 bugs in huge page support. [SPARC64]: CONFIG_BLK_DEV_RAM fix [SPARC64]: Optimized TSB table initialization. [SPARC64]: Allow CONFIG_MEMORY_HOTPLUG to build. [SPARC64]: Use SLAB caches for TSB tables. [SPARC64]: Don't kill the page allocator when growing a TSB. [SPARC64]: Randomize mm->mmap_base when PF_RANDOMIZE is set. [SPARC64]: Increase top of 32-bit process stack. [SPARC64]: Top-down address space allocation for 32-bit tasks. [SPARC64] bbc_i2c: Fix cpu check and add missing module license. [SPARC64]: Fix and re-enable dynamic TSB sizing. [SUNSU]: Fix missing spinlock initialization. [TG3]: Do not try to access NIC_SRAM_DATA_SIG on Sun parts. [SPARC64]: First cut at VIS simulator for Niagara. [SPARC64]: Fix system type in /proc/cpuinfo and remove bogus OBP check. [SPARC64]: Add SMT scheduling support for Niagara. [SPARC64]: Fix 32-bit truncation which broke sparsemem. [SPARC64]: Move over to sparsemem. [SPARC64]: Fix new context version SMP handling. ...
