i386: Set MCG_STATUS_RIPV bit for mce SRAR error
In the physical machine environment, when a SRAR error occurs, the IA32_MCG_STATUS RIPV bit is set, but qemu does not set this bit. When qemu injects an SRAR error into virtual machine, the virtual machine kernel just call do_machine_check() to kill the current task, but not call memory_failure() to isolate the faulty page, which will cause the faulty page to be allocated and used repeatedly. If used by the virtual machine kernel, it will cause the virtual machine to crash Signed-off-by: luofei <luofei@unicloud.com> Message-Id: <20220120084634.131450-1-luofei@unicloud.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
