[MIPS] Fix sparsemem support. Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem extreme, this function does an allocate for bootmem. This would always fail since init_bootmem hasn't been called yet. Move memory_present after free_bootmem. This only marks actual memory ranges as present instead of the entire address space.

MIPS: Control huge tlb support via Kconfig symbol MIPS_HUGE_TLB_SUPPORT We need Huge TLBs for HUGETLB_PAGE, or the soon to follow TRANSPARENT_HUGEPAGE. collect this information under a single Kconfig symbol.

MIPS: Handle huge pages with 64KB base page size. When using sparsemem, we need to adjust some constants as the resulting huge pages are 512MB in size.

MIPS: Whitespace cleanup. Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2013-01-22 12:59:30 +01:00			`#define MAX_PHYSMEM_BITS 35`
