Balbir Singh de3b87611d powerpc/mm/book(e)(3s)/64: Add page table accounting ... Introduce a helper pgtable_gfp_flags() which just returns the current gfp flags and adds __GFP_ACCOUNT to account for page table allocation. The generic helper is added to include/asm/pgalloc.h and has two variants - WARNING ugly bits ahead 1. If the header is included from a module, no check for mm == &init_mm is done, since init_mm is not exported 2. For kernel includes, the check is done and required see (3e79ec7 arch: x86: charge page tables to kmemcg) The fundamental assumption is that no module should be doing pgd/pud/pmd and pte alloc's on behalf of init_mm directly. NOTE: This adds an overhead to pmd/pud/pgd allocations similar to x86. The other alternative was to implement pmd_alloc_kernel/pud_alloc_kernel and pgd_alloc_kernel with their offset variants. For 4k page size, pte_alloc_one no longer calls pte_alloc_one_kernel.
