#     powerpc/pkeys: Deny read/write/execute by default
#     
#     Deny all permissions on all keys, with some exceptions.  pkey-0 must
#     allow all permissions, or else everything comes to a screaching halt.
#     Execute-only key must allow execute permission.
#     
#     Fixes: cf43d3b26452 ("powerpc: Enable pkey subsystem")
