Hi Vineet, It seems arc architecture supports CONFIG_TRANSPARENT_HUGEPAGE, but it doesn't define HPAGE_SIZE. 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?
Should I just compile out this code for arc architecture specifically?
