Currently it's impossible to get CPU's microcode revision from Xen after
late loading without looking into Xen logs which is not always convenient.
Add an option to xen-ucode tool to print the currently loaded ucode
revision.
Sergey Dyasli (3):
tools/xenctrl: add xc_get_cpu_version()
x86/platform: introduce XENPF_get_ucode_revision
tools/xen-ucode: print information about currently loaded ucode
