Oh, it is because of commit e2ffa15b9baa ("kbuild: Disable
CC_HAS_ASM_GOTO_OUTPUT on clang < 17"). Prior to that change, all
supported versions of clang would use the CONFIG_CC_HAS_ASM_GOTO_OUTPUT
blocks in arch/powerpc/include/asm/uaccess.h, whereas now clang-15 and
clang-16 will use the variants without asm goto with outputs.
Cheers,
