Subject: [PATCH 4.14 01/17] powerpc/64s: Define MASKABLE_RELON_EXCEPTION_PSERIES_OOL

From: Daniel Axtens <dja@...ens.net>

Commit da2bc4644c75 ("powerpc/64s: Add new exception vector macros")
adds:

+#define __TRAMP_REAL_VIRT_OOL_MASKABLE(name, realvec)          \
+       TRAMP_REAL_BEGIN(tramp_virt_##name);                            \
+       MASKABLE_RELON_EXCEPTION_PSERIES_OOL(realvec, name##_common);   \

However there's no reference there or anywhere else to
MASKABLE_RELON_EXCEPTION_PSERIES_OOL and an attempt to use it
unsurprisingly doesn't work.

Add a definition provided by mpe.
