Hi and welcome to LKML!

Based on your patch, here are my notes:

  * Write the patch description in imperative mood (e.g. it should have
    been "Remove redundant inner tx_irq_disabled conditional in
    mace_interrupt() since it has already been handled". Wrap it in about
    72-75 column wide (to account indentation in git-log(1) so that the
    total line length is at maximum 80).
  * Write also short but concise patch subject (one-line summary), while also
    paying attention to the subject prefix. In this
    case, it should have been "net: amd: remove inner tx_irq_disabled
    conditional".
  * Your patch looks like corrupted (tabs converted to spaces, linewrapped,
    etc.). Please configure your email-client not to do such things, or better
    yet, use git-send-email(1) to send patches.
  * You need to Cc: relevant maintainers and lists, which can be obtained
    by `scripts/get_maintainer.pl -norolestats -separator , -- 
    /path/to/your/patch`. Personally I put lists in To: header and individual
    addresses in Cc:. I have added them for you.
  * Last but not least, build the kernel with your patch applied (preferably
    enable W=1 and CONFIG_WERROR and also cross-compile).

Dunno if you need to also handle the else case (that gives "Re-entering" msg)
in the outer conditional.

Thanks.
