Thomas Gleixner be6fcb5478 x86/bugs: Rework spec_ctrl base and mask logic ... x86_spec_ctrL_mask is intended to mask out bits from a MSR_SPEC_CTRL value which are not to be modified. However the implementation is not really used and the bitmask was inverted to make a check easier, which was removed in "x86/bugs: Remove x86_spec_ctrl_set()" Aside of that it is missing the STIBP bit if it is supported by the platform, so if the mask would be used in x86_virt_spec_ctrl() then it would prevent a guest from setting STIBP. Add the STIBP bit if supported and use the mask in x86_virt_spec_ctrl() to sanitize the value which is supplied by the guest.
