From 32231879f66162352fc6f3041c5c2b1d965879b2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 4 May 2015 09:52:42 +0200 Subject: [PATCH] x86/fpu/init: Propagate __init annotations Now that all the FPU init function call dependencies are cleaned up we can propagate __init annotations deeper. This shrinks the runtime size of the kernel a bit, and also addresses a few section warnings. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.
