[Xen-devel] [PATCH v9 08/25] x86: refactor psr: L3 CAT: implement get value flow.

There is an interface in user space to show feature value of domains. This patch implements get value flow in hypervisor including L3 CAT callback function. It also changes domctl interface to make it more general. With this patch, 'psr-cat-show' can work for L3 CAT but not for L3 code/data
