[PULL 7/9] target/i386: Add new bit definitions of MSR_IA32_ARCH_CAPABILITIES

Posted by Paolo Bonzini 2 years, 7 months ago

From: Tao Su <tao1.su@linux.intel.com>

Currently, bit 13, 14, 15 and 24 of MSR_IA32_ARCH_CAPABILITIES are
disclosed for fixing security issues, so add those bit definitions.
