arm64/mm: fix variable 'pud' set but not used
GCC throws a warning, arch/arm64/mm/mmu.c: In function 'pud_free_pmd_page': arch/arm64/mm/mmu.c:1033:8: warning: variable 'pud' set but not used [-Wunused-but-set-variable] pud_t pud; ^~~ because pud_table() is a macro and compiled away. Fix it by making it a static inline function and for pud_sect() as well. Signed-off-by: Qian Cai <cai@lca.pw> Signed-off-by: Will Deacon <will@kernel.org>
