2016-05-01	powerpc/mm: Abstraction for vmemmap and map_kernel_page()	Aneesh Kumar K.V	1	-6/+6
	For hash we create vmemmap mapping using bolted hash page table entries. For radix we fill the radix page table. The next patch will add the radix details for creating vmemmap mappings.

2016-05-01	powerpc/mm: Make page table size a variable	Aneesh Kumar K.V	1	-0/+1
	Radix and hash MMU models support different page table sizes. Make the #defines a variable so that existing code can work with variable sizes. Slice related code is only used by hash, so use hash constants there. We will replicate some of the boundary conditions with resepct to TASK_SIZE using radix values too. Right now we do boundary condition check using hash constants. Swapper pgdir size is initialized in asm code. We select the max pgd size to keep it simple. For now we select hash pgdir. When adding radix we will switch that to radix pgdir which is 64K. BUILD_BUG_ON check which is removed is already done in hugepage_init() using MAYBE_BUILD_BUG_ON().

2016-05-01	powerpc/mm: Move hash and no hash code to separate files	Aneesh Kumar K.V	1	-0/+94
	This patch reduces the number of #ifdefs in C code and will also help in adding radix changes later. Only code movement in this patch.
