* [ARM] 5349/1: VFP: Add PM code to save and restore current VFP stateBen Dooks2008-12-18
| | | | | | | | | | | | | | | | | | | | | When CONFIG_PM is selected, the VFP code does not have any handler installed to deal with either saving the VFP state of the current task, nor does it do anything to try and restore the VFP after a resume. On resume, the VFP will have been reset and the co-processor access control registers are in an indeterminate state (very probably the CP10 and CP11 the VFP uses will have been disabled by the ARM core reset). When this happens, resume will break as soon as it tries to unfreeze the tasks and restart scheduling. Add a sys device to allow us to hook the suspend call to save the current thread state if the thread is using VFP and a resume hook which restores the CP10/CP11 access and ensures the VFP is disabled so that the lazy swapping will take place on next access.

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>
