Hi Arnd,

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")

Who should take this patch ? I expected it to be merged by Arnd as asm-generic maintainer but this is the second time I resend.

Should the patch go via riscv tree instead as the undue pud_user() was initialy introduced by riscv ?

v2: Change ARM64 pud_user macro to pud_user(pud)

This one looks like it should go upstream through you?

If you'd prefer arch/riscv to pick it up, let us know.


thanks,
