From: Xin Li <xin3.li@xxxxxxxxx>
Move the bit defines for MSR_IA32_VMX_BASIC from msr-index.h to vmx.h so
that they are colocated with other VMX MSR bit defines, and with the
helpers that extract specific information from an MSR_IA32_VMX_BASIC value.
Opportunistically use BIT_ULL() instead of open coding hex values.
Opportunistically rename VMX_BASIC_64 to VMX_BASIC_32BIT_PHYS_ADDR_ONLY,
as "VMX_BASIC_64" is widly misleading. The flag enumerates that addresses
are limited to 32 bits, not that 64-bit addresses are allowed.
Last but not least, opportunistically #define DUAL_MONITOR_TREATMENT so
that all known single-bit feature flags are defined (this will allow
replacing open-coded literals in the future).
