From 2613265cb5b07a46bc01eb67202874136efd7049 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 16 Dec 2015 21:10:22 +1100 Subject: [PATCH] powerpc/kernel: Combine vec/loc for STD_EXCEPTION_PSERIES The STD_EXCEPTION_PSERIES macro takes both a vector number, and a location (memory address). However both are always identical, so combine them to save repeating ourselves. This does mean an exception handler must always exist at the location in memory that matches its vector number. But that's OK because this is the "STD" macro (standard), which does exactly that. We have other macros for the other cases, eg. STD_EXCEPTION_PSERIES_OOL (out of line).
