[PATCH] x86/cpu-policy: Advertise MSR_ARCH_CAPS to guests by default

2023-07-25 Thread Andrew Cooper
With xl/libxl now able to control the policy bits for MSR_ARCH_CAPS, it is safe to advertise to guests by default. In turn, we don't need the special case to expose details to dom0. This advertises MSR_ARCH_CAPS to guests on *all* Intel hardware, even if the register content ends up being empty.
