From d7bfc9ffd58037ff86f9fd0c3cef77cccb555da3 Mon Sep 17 00:00:00 2001 From: Xin Li Date: Wed, 5 Jun 2024 16:19:12 -0700 Subject: [PATCH] KVM: VMX: Move MSR_IA32_VMX_BASIC bit defines to asm/vmx.h 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).
