Subject: [patch 0/9] x86: AMD microcode patch loading support
This patch set introduces microcode patch loading support for AMD processors. It includes refactoring
of existing code to allow code sharing. Vendor specific code has been split off, leading to a
multi-module solution as compared to the current single-module approach.
Thanks,
Peter Oruba

Subject: [patch 1/9] [PATCH 1/9] x86: Moved Intel microcode patch loader declarations to seperate header file.
References: <20080725161723.636932280@....com>
Content-Disposition: inline; filename=0001-x86-Moved-Intel-microcode-patch-loader-declarations.patch
Intel specific microcode declarations have been moved to a seperate header file.
There are no code changes to the code itself and no side effects to other parts.
