Subject: RAS/CEC: Dump the different array element sections
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f57518cd56e2919afbcef3839122a75e291c7f85;p=linux.git

RAS/CEC: Dump the different array element sections

When dumping the array elements, print them in the following format:

  [ PFN | generation in binary | count ]

to be perfectly clear what all those sections are.
