From 3027a37c06be364e6443d3df3adf45576fba50cb Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Sun, 18 Apr 2021 23:16:41 +1000 Subject: powerpc: Only define _TASK_CPU for 32-bit We have some interesting code in our Makefile to define _TASK_CPU, based on awk'ing the value out of asm-offsets.h. It exists to circumvent some circular header dependencies that prevent us from referring to task_struct in the relevant code. See the comment around _TASK_CPU in smp.h for more detail. Maybe one day we can come up with a better solution, but for now we can at least limit that logic to 32-bit, because it's not needed for 64-bit.
