From b19ae3999891cad21a3995c34d313dda5df014e2 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 4 Sep 2009 10:00:09 -0700 Subject: [PATCH] x86, msr: change msr-reg.o to obj-y, and export its symbols Change msr-reg.o to obj-y (it will be included in virtually every kernel since it is used by the initialization code for AMD processors) and add a separate C file to export its symbols to modules, so that msr.ko can use them; on uniprocessors we bypass the helper functions in msr.o and use the accessor functions directly via inlines.
