Subject[PATCH 00/16] x86/microcode/AMD: Improve container verification

Hi all,

the time to redo all the ideas properly, split it in self-contained,
logical chunks and test it.

Reveiew and comments are appreciated.

x86/microcode/AMD: Move verify_patch_size() up in the file
x86/microcode/AMD: Clean up per-family patch size checks
x86/microcode/AMD: Cleanup verify_patch_size() more
x86/microcode/AMD: Concentrate patch verification
x86/microcode/AMD: Simplify patch family detection
x86/microcode/AMD: Move patch family check to verify_patch()
x86/microcode/AMD: Move chipset-specific check into verify_patch()
x86/microcode/AMD: Change verify_patch()'s return value
x86/microcode/AMD: Convert early parser to the new verification routines
x86/microcode/AMD: Fix container size's type
