[PATCH 0/4][Xen-devel] update current microcode logic and add microcode S3 support

["Liu, Jinsong" <jinsong.liu@xxxxxxxxx>]

These patches are used to add microcode S3 support.
However, current xen microcode logic has some issues, so before we add 
microcode S3 support, we update some current microcode logic.

patch1/4: microcode-1-remove-redundant.patch
X86 microcode: cancel redundant input parameter of microcode functions
Cancel redundant input parameter 'uci', since it can get from another input 
parameter 'cpu' as index.

patch2/4: microcode-2-update.patch
X86 microcode: microcode logic update
Update microcode logic:
1. separate microcode_fini_cpu() into 2 level to avoid deadlock (when fail at 
microcode_update_cpu);
2. cancel redundant collect_cpu_info at microcode.c level, use relative 
function at microcode driver level;
3. separate microcode_resume_cpu from microcode_update_cpu, because it's 
redundant (should only be called when S3 wakeup) and will block newer microcode 
update when user update newer microcode.dat from user level;

patch3/4: microcode-3-optimizing.patch
X86 microcode: optimizing microcode update
It's possible the data file has multiple matching ucode, we needn't to update 
multiple times, just keep searching the latest version, and update once.

patch4/4: microcode-4-s3.patch
X86 microcode: add S3 micorcode update
When wakeup from S3, use per cpu microcode image to update cpu microcode.


Thanks,
Jinsong
