It only defines PAGE_SIZE in include/uapi/asm/page.h? AFAIK HPAGE_SIZE must be defined when CONFIG_TRANSPARENT_HUGEPAGE is enabled. What can be the solution here for arc? The remaining build failures are because the wrong tree. I base my patches on latest next, while the bot has based patches on mm-everything. I guess today's next would have latest mm stuff, a rebase would make things correct or I'll shift to mm-everything. -- BR, Muhammad Usama Anjum
