Modified files:
sys/sparc64/sparc64 exception.S swtch.S
Log:
Add support for saving and restoring kernel floating point state. The state
will be saved if we context switch as a result of an interrupt which occured
while using the floating point registers in the kernel (which actually can't
happen right now). This allows fp disabled traps in the kernel, which
normally shouldn't happen, so make sure the trapping code is what we expect
it is.
