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") #
