[Xen-devel] [PATCH] Add XSAVE/XRSTOR support to Xen

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

The attached patch adds the support of XSAVE/XRSTOR infrastructure for x86.
XSAVE/XRSTOR manages the existing and future processor extended states on x86 
architecture.

XSAVE/XRSTOR related stuff is defined in Intel SDMs (The latest version is Nov. 
2008):
http://www.intel.com/products/processor/manuals/ 

The patch uses the classical CR0.TS based lazy algorithm.
For now only FPU/SSE states (The bit 0 and 1 of XCR0) is supported.
