Hi everyone,
I built next-20220715 tree, using powerpc64-unknown-linux-gnu-gcc
(GCC 12.1.0) and ps3_defconfig. The build errored on W=1 build
(-Werror=missing-prototypes):
CC arch/powerpc/mm/book3s64/pgtable.o
CC arch/powerpc/kernel/process.o
arch/powerpc/mm/book3s64/pgtable.c:478:5: error: no previous prototype for
'pmd_move_must_withdraw' [-Werror=missing-prototypes]
478 | int pmd_move_must_withdraw(struct spinlock *new_pmd_ptl,
| ^~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
The errored line is introduced by commit 579b9239c1f386 ("powerpc/radix: Fix
kernel crash with mremap()")
Looking at the commit, it seems like GCC didn't see the prototype which had
already been given, or am I missing something?
Thanks.
