For the past few days arm64 has been failing to build in -next due to:
arm64-allmodconfig../mm/gup.c:963:3: error: implicit declaration of function 'pgd_huge' [-Werror=implicit-function-declaration]
arm64-defconfig../mm/gup.c:963:3: error: implicit declaration of function 'pgd_huge' [-Werror=implicit-function-declaration]
which appears to be due to "mm/gup.c: update generic gup implementation to handle hugepage directory". That patch added a default definition of pgd_huge() in the !CONFIG_HUGETLB_PAGE case but only PowerPC provides an actual definition of that function.
The patch responsible for this has been removed from -mm (because of this issue), I think it will leave -next too?
