Apparently there's some config option you've enabled that is causing it to fail but I can't find it. defconfig works fine on my mips crosscompiler and allyesconfig is borked already in other ways. This is definitely the wrong fix, anyway, and it would require a change to arch/mips/include/asm/page.h instead since it's localized to mips, so nack. > Signed-off-by: David Daney <david.daney@xxxxxxxxxx> > --- > include/linux/hugetlb.h | 1 + > 1 files changed, 1 insertions(+), 0 deletions(-) > > diff --git a/include/linux/hugetlb.h b/include/linux/hugetlb.h > index 19644e0..746d543 100644 > --- a/include/linux/hugetlb.h > +++ b/include/linux/hugetlb.h > @@ -113,6 +113,7 @@ static inline void copy_huge_page(struct page *dst, struct page *src) > #ifndef HPAGE_MASK > #define HPAGE_MASK PAGE_MASK /* Keep the compiler happy */ > #define HPAGE_SIZE PAGE_SIZE > +#define HPAGE_SHIFT PAGE_SHIFT > #endif > > #endif /* !CONFIG_HUGETLB_PAGE */
