We see this build regression on PowerPC with GCC-8 and GCC-12:
-----8<-----
/builds/linux/arch/powerpc/kernel/rtas_flash.c: In function 'rtas_flash_init':
/builds/linux/arch/powerpc/kernel/rtas_flash.c:717:22: error: implicit declaration of function 'kmem_cache_create_usercopy'; did you mean 'kmem_cache_create'? [-Werror=implicit-function-declaration]
flash_block_cache = kmem_cache_create_usercopy("rtas_flash_cache",
^~~~~~~~~~~~~~~~~~~~~~~~~~
kmem_cache_create
/builds/linux/arch/powerpc/kernel/rtas_flash.c:717:20: error: assignment to 'struct kmem_cache *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
flash_block_cache = kmem_cache_create_usercopy("rtas_flash_cache",
^
----->8-----
That's on defconfig and cell_defconfig.
Bisection points to "powerpc/rtas_flash: allow user copy to flash block cache objects" (5190538c66e5). Reverting that patch makes the build pass again.
Tuxmake reproducer:
#pip3 install -U tuxmake
tuxmake --runtime podman --target-arch powerpc --toolchain gcc-8 --kconfig defconfig
git revert 5190538c66e5e8e7cdbf694afec8291f421e6bcf
tuxmake --runtime podman --target-arch powerpc --toolchain gcc-8 --kconfig defconfig
Greetings!
