Now that _exception no longer calls _exception_pkey it is no longer
necessary to handle any signal with any si_code.  All pkey exceptions
are SIGSEGV with paired with SEGV_PKUERR.  So just handle
that case and remove the now unnecessary parameters from _exception_pkey.

Looks fine to me (small query below).

In the patch title, s/poewrpc/powerpc


        clear_siginfo(&info);
-       info.si_signo = signr;
-       info.si_code = code;
+       info.si_signo = SIGSEGV;
+       info.si_code = SEGV_PKUERR;
        info.si_addr = (void __user *) addr;
        info.si_pkey = key;
- force_sig_info(signr, &info, current);
+       force_sig_info(info.si_signo, &info, current);
                        ^^^^^^^^^^^^^
Why not just SIGSEGV?
