From c03be0a3f3cc656eab5c427b78959b8f1b169a11 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Sun, 27 Nov 2022 22:49:32 +1000 Subject: powerpc: add definition for pt_regs offset within an interrupt frame This is a common offset that currently uses the overloaded STACK_FRAME_OVERHEAD constant. It's easier to read and more flexible to use a specific regs offset for this.
