    x86/ucode/amd: Fix microcode payload size for Fam19 processors
    
    The original limit provided wasn't accurate.  Blobs are in fact rather larger.

    x86/ucode/amd: Handle length sanity check failures more gracefully
    
    Currently, a failure of verify_patch_size() causes an early abort of the
    microcode blob loop, which in turn causes a second go around the main
    container loop, ultimately failing the UCODE_MAGIC check.
    
    First, check for errors after the blob loop.  An error here is unrecoverable,
    so avoid going around the container loop again and printing an
    unhelpful-at-best error concerning bad UCODE_MAGIC.
    
    Second, split the verify_patch_size() check out of the microcode blob header
    check.  In the case that the sanity check fails, we can still use the
    known-to-be-plausible header length to continue walking the container to
    potentially find other applicable microcode blobs.
    
    Before:
      (XEN) microcode: Bad microcode data
      (XEN) microcode: Wrong microcode patch file magic
      (XEN) Parsing microcode blob error -22
    
    After:
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa000
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa010
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa011
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa200
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa210
      (XEN) microcode: Bad microcode length 0x000015c0 for cpu 0xa500
      (XEN) microcode: couldn't find any matching ucode in the provided blob!

    x86/ucode/amd: Fix OoB read in cpu_request_microcode()
    
    verify_patch_size() is a maximum size check, and doesn't have a minimum bound.
    
    If the microcode container encodes a blob with a length less than 64 bytes,
    the subsequent calls to microcode_fits()/compare_header() may read off the end
    of the buffer.

    autoconf: check endian.h include path
    
    Introduce an autoconf macro to check for the include path of certain
    headers that can be different between OSes.
    
    Use such macro to find the correct path for the endian.h header, and
    modify the users of endian.h to use the output of such check.
