[Xen-devel] [PATCH] update microcode support



Hi,

Attached patch updates microcode patch loading support:

- Container header file holding the patches changed. Update to new format.
- in cpu_request_microcode() move heap re-allocation & copy out of the loop.
  Side-effect: Remove limitation in only supporting fixed sized
  microcode patches. Also simplifies code a lot.
- cleanup: use rdmsr and wrmsrl instead of inlined assembler
- pass ucode_cpu_info as arguments. Improves reentrancy.
- cleanup: simplify struct ucode_cpu_info and remove
  get_matching_microcode hook. Side-effect: reduces kernel size.
- bugfix: fix xen kernel memory leak in error path. equiv_cpu_table
  was not freed.
