Commit c01013a2f8dd ("powerpc: add asm/stat.h to UAPI compile-test coverage") converted as follows:
uid_t --> __kernel_uid_t gid_t --> __kernel_gid_t
The bit width of __kernel_{uid,gid}_t is 16 or 32-bits depending on architectures.
PPC uses 32-bits for them as in include/uapi/asm-generic/posix_types.h, so the previous conversion is probably fine, but let's stick to the arch-independent conversion just in case.
The safe replacements across all architectures are:
uid_t --> __kernel_uid32_t gid_t --> __kernel_gid32_t
as defined in include/linux/types.h.
A similar issue was reported for the android binder. [1]
