struct rpc_procinfo contains function pointers, and marking it as

p_count is the only writeable memeber of struct rpc_procinfo, which is

Pull key subsystem fixes from James Morris:
 "Here are a bunch of fixes for Linux keyrings, including:

   - Fix up the refcount handling now that key structs use the
     refcount_t type and the refcount_t ops don't allow a 0->1
     transition.

   - Fix a potential NULL deref after error in x509_cert_parse().

   - Don't put data for the crypto algorithms to use on the stack.

   - Fix the handling of a null payload being passed to add_key().

   - Fix incorrect cleanup an uninitialised key_preparsed_payload in
     key_update().

   - Explicit sanitisation of potentially secure data before freeing.

   - Fixes for the Diffie-Helman code"

Commit abb2ea7d ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.

So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.

Maybe this makes clang happier.
