From c460b5d34018d71fdeb8540620690883db3f959b Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Wed, 30 Jul 2014 23:53:34 -0700 Subject: x86, apic: Remove mps_oem_check callback Since commit b5660ba76b41 ("x86, platforms: Remove NUMAQ") removed NUMAQ, the mps_oem_check() apic callback has been obsolete. Remove it. This allows generic_mps_oem_check() to be removed as well.
