Ben Dooks fc0b7a2036 [ARM] 5349/1: VFP: Add PM code to save and restore current VFP state ... 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.
