[PATCH 1/3] x86: move ARCH_LOCKDEP_SYS_EXIT[IRQ] defines closer to their users

From: Denys Vlasenko
Date: Fri Feb 27 2015 - 19:30:22 EST


This change simply moves defines around (even if it's not obvious in a patch form).
Nothing is changed.

This is a preparation for folding ARCH_LOCKDEP_SYS_EXIT defines into their users.
