#     powerpc/mm: Fix CONFIG_PPC_KUAP_DEBUG on PPC32
#     
#     CONFIG_PPC_KUAP_DEBUG is not selectable because it depends on PPC_32
#     which doesn't exists.
#     
#     Fixing it leads to a deadlock due to a vital register getting
#     clobbered in _switch().
#     
#     Change dependency to PPC32 and use r0 instead of r4 in _switch()
#     
#     Fixes: e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access Protection")
