Commit 2c8a81dc0cc5 ("riscv/mm: fix two page table check related issues") added pud_user() in include/asm-generic/pgtable-nopmd.h But pud_user() only exists on ARM64 and RISCV and is not expected by any part of MM. Add the missing definition in arch/riscv/include/asm/pgtable-32.h and remove it from asm-generic/pgtable-nopmd.h A stub pud_user() is also required for ARM64 after commit ed928a3402d8 ("arm64/mm: fix page table check compile error for CONFIG_PGTABLE_LEVELS=2") Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Reviewed-by: Peter Xu <peterx@redhat.com> Reviewed-by: Oscar Salvador <osalvador@suse.de> --- v3: Added pud_user() for arm64 --- arch/arm64/include/asm/pgtable.h | 1 + arch/riscv/include/asm/pgtable-32.h | 5 +++++ include/asm-generic/pgtable-nopmd.h | 1 - 3 files changed, 6 insertions(+), 1 deletion(-)
