x86 Fix VMI crash on boot in 2.6.28-rc8
VMI initialiation can relocate the fixmap, causing early_ioremap to malfunction if it is initialized before the relocation. To fix this, VMI activation is split into two phases; the detection, which must happen before setting up ioremap, and the activation, which must happen after parsing early boot parameters. This fixes a crash on boot when VMI is enabled under VMware. Signed-off-by: Zachary Amsden <zach@vmware.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
