[Qemu-devel] [PULL 4/4] i386: Add "stibp" flag name

[Eduardo Habkost]

The STIBP flag may be supported by the host KVM module, so QEMU
can allow it to be configured manually, and it can be exposed to
guests when using "-cpu host".

No additional migration code is required because the whole
contents of spec_ctrl is already migrated in the "cpu/spec_ctrl"
section.

Corresponding KVM patch was submitted at:
