Hi all,

In v8, addressed Jason's comments:

- Changed kgdb_enable_nmi() weak function to kgdb_arch callbck;
- We no longer register disable_nmi command if arch does not register
  KGDB NMI handling (i.e. not filling kgdb_arch.enable_nmi callback);
- The same is for ttyNMI: if architecure does not provide us with
  enable_nmi call, we don't need the tty device. Of course, there is no
  way to tell wether a specific serial device can be used for NMI
  debugging, as it is not serial-device specific, but specific to
  whether IRQ can be rerouted to an NMI (for most our cases, pretty
  much every IRQ can be rerouted, e.g. a hot-pluggable serial device on
  a PCI bus).
- Rebased on the latest and greatest tty-next, just in case.

I have the kgdb regression builder running right now (it will be done in about 1 hour), and so far it picked up one new warning.

drivers/tty/serial/kgdb_nmi.c: In function 'kgdb_nmi_poll_one_knock':
drivers/tty/serial/kgdb_nmi.c:161: warning: field width should have type 'int', but argument 4 has type 'size_t'

Hi Anton,

You can add my ack to the series, for what you have in: "git://git.infradead.org/users/cbou/linux-nmi-kdb.git master", and then drop a pull request to Greg for the next merge window.  Thank you for your hard work through all the revisions of this code and this slick new feature.
