[PATCH] x86 microcode: add sysfs and hotplug support
Add sysfs support. Currently each CPU has three microcode related attributes. One is 'version' which shows current ucode version of CPU. Tools can use the attribute do validation or show CPU ucode status. one is 'reload' which allows manually reloading ucode. Another is 'processor_flags', which exports processor flags, so we can write tools to check if CPU has latest ucode. Also add suspend/resume and CPU hotplug support.
