Subject: [PATCH 4.14 098/101] x86/pkeys/selftests: Rename si_pkey to siginfo_pkey

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dave Hansen <dave.hansen@...ux.intel.com>

commit 91c49c2deb96ffc3c461eaae70219d89224076b7 upstream.

'si_pkey' is now #defined to be the name of the new siginfo field that
protection keys uses.  Rename it not to conflict.
