From 731dade128ebc35044e7f9b9d396e4c1bed6ecbc Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 11 Sep 2019 21:57:45 +1000 Subject: [PATCH] powerpc/kvm: Explicitly mark kvm guest code as __init All the code in kvm.c can be marked __init. Most of it is already inlined into the initcall, but not all. So instead of relying on the inlining, mark it all as __init. This saves ~280 bytes of text for my configuration.
