[Xen-devel] [PATCH 1/3] HVM: Support XSAVE/XRSTOR and AVX for AMD CPUs
Move xsave initialization code to a common place
This patch moves xsave/xrstor code to CPU common file. First of all, it
prepares xsave/xrstor support for AMD CPUs. Secondly, Xen would crash on
__context_switch() without this patch on xsave-capable AMD CPUs. The
crash was due to cpu_has_xsave reports true in domain.c while xsave
space wasn't initialized.
