Message

This series of patches adds support for extended physical address on newer
AMD processors such as AMD 'Milan'.

The first patch provides a fix to avoid unnecessary padding in mce_bank
struct.

The second patch defines a separate helper function to extract
MCA_ADDR[ErrorAddr].

Finally, the last patch adds support for extended ErrorAddr bits in
MCA_ADDR.
