Jeremy Fitzhardinge a789ed5fb6 xen: cache cr0 value to avoid trap'n'emulate for read_cr0 ... stts() is implemented in terms of read_cr0/write_cr0 to update the state of the TS bit. This happens during context switch, and so is fairly performance critical. Rather than falling back to a trap-and-emulate native read_cr0, implement our own by caching the last-written value from write_cr0 (the TS bit is the only one we really care about). Impact: optimise Xen context switches Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>		2009-05-08 15:55:24 -07:00
