2015-11-30OvmfPkg: SmmCpuFeaturesLib: customize state save map formatPaolo Bonzini
This adjusts the previously introduced state save map access functions, to account for QEMU and KVM's 64-bit state save map following the AMD spec rather than the Intel one.

2015-11-30OvmfPkg: SmmCpuFeaturesLib: implement SMRAM state save map accessPaolo Bonzini
This implementation copies SMRAM state save map access from the PiSmmCpuDxeSmm module. The most notable change is: - dropping support for EFI_SMM_SAVE_STATE_REGISTER_IO - changing the implementation of EFI_SMM_SAVE_STATE_REGISTER_LMA to use the SMM revision id instead of a local variable (which UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.c initializes from CPUID's LM bit). This accounts for QEMU's implementation of x86_64, which always uses revision 0x20064 even if the LM bit is zero.
