From 904f81f3f36d84a4d26c712a9c7741a397a4f348 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 28 Jun 2019 15:33:30 +1000 Subject: [PATCH] powerpc/64s/exception: denorm handler use standard scratch save macro Although the 0x1500 interrupt only applies to bare metal, it is better to just use the standard macro for scratch save. Runtime code path remains unchanged (due to instruction patching).
