Hi All, This patch series attempt to update book3s 64 linux page table format to make it more flexible. Our current pte format is very restrictive and we overload multiple pte bits. This is due to the non-availability of free bits in pte_t. We use pte_t to track the validity of 4K subpages. This patch series free up pte_t of 11 bits by moving 4K subpage tracking to the lower half of PTE page. The pte format is updated such that we have a better method for identifying a pte entry at pmd level. This will also enable us to implement hugetlb migration(not yet done in this series).Hi, what tree does this apply to?linux-powerpc tree -next branch https://git.kernel.org/cgit/linux/kernel/git/powerpc/linux.git/
Ok, but I'm getting the following error after applying the first patch from your series: error: patch failed: arch/powerpc/include/asm/pgalloc-64.h:166 error: arch/powerpc/include/asm/pgalloc-64.h: patch does not apply error: arch/powerpc/mm/hash64_64k.c: No such file or directory kda@hydra ~/devel/linux $ git branch master * next kda@hydra ~/devel/linux $ git remote show origin * remote origin Fetch URL: git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git Push URL: git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git Or am I missing something?
