Subject[PATCH V2 0/2] x86/microcode/amd: early loading fixes
This patchset addreses two problems with early loading on AMD.

First, feedback from Yinghai that find_ucode_in_initrd() should be
marked __init:

And second, feedback from Henrique that Intel early loading supports
multiple microcode firmware concatenated together, whereas the current
AMD implementation lacks this support:

* test for !initrd_start before using it
* use __pa() instead of __pa_nodebug() on AP load
* fixed calculation of start offset and size of the microcode container file

Jacob Shin (2):
x86/microcode/amd: make find_ucode_in_initrd() __init
x86/microcode/amd: allow multiple families' bin files appended
