The check for __HAVE_ARCH_HUGE_PTEP_GET comes before the definition,
leading to an extraneous definition of huge_ptep_get:
In file included from arch/arm/include/asm/hugetlb.h:28,
from include/linux/hugetlb.h:456,
from arch/arm/kvm/../../../virt/kvm/arm/mmu.c:22:
arch/arm/include/asm/hugetlb-3level.h:33:21: error: redefinition of 'huge_ptep_get'
static inline pte_t huge_ptep_get(pte_t *ptep)
Change the header file inclusions to be in the correct order for
this to work.

I have noticed this build error on linux next tree for arm32 build.
Thanks for the fix.

Thanks Arnd, this change intervened in v5, that seemed straightforward
enough...Sorry about that, and thanks for your fix.
