If a watchdog driver has decided it is time to reboot the system
we know something is wrong and we are in interrupt context
so emergency_reboot() is what we want.

sysrq calls into the reboot path from an interrupt handler
we can either push the code do into process context and
call kernel_restart and get a clean reboot or we can simply
reboot the machine, and increase our chances of actually
rebooting. emergency_reboot() seems like the closest match
to what we have previously done, and what we want.

Put NETCONSOLE and NETPOLL options together since they are related.
This cuts down on the hassle of flipping back and forth between
the Networking menu and the Network drivers menu to change their

gconfig has a small problem with this. I think that it's
a bug in gconfig and I will take it up with Romain Lievin.

scsi_init_io calls scsi_alloc_sgtable and then calls blk_rq_map_sg
to initialize the scatterlist structure. blk_rq_map_sg() already
memset the structure for every new segment. That makes the memset
in scsi_alloc_sgtable unnecessary.

One of the issues we had was reverting the midlayers lun value
into the 8byte lun value that we wanted to send to the device.
Historically, there's been some combination of byte swapping,
setting high/low, etc. There's also been no common thread between
how our driver did it and others. I also got very confused as
to why byteswap routines were being used.
Anyway, this patch is a LLDD-callable function that reverts the
midlayer's lun value, stored in an int, to the 8-byte quantity
(note: this is not the real 8byte quantity, just the same amount
that scsilun_to_int() was able to convert and store originally).
This also solves the dilemma of the thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112116767118981&w=2
A patch for the lpfc driver to use this function will be along
in a few days (batched with other patches).

Cleanup FC remote port registration.
Due to the inherent behaviour (an immediate scan) of adding
a 'target'-role-capable rport via fc_remote_port_add(),
split the registration into two steps -- addition as
unknown-type role, then use fc_remote_port_rolchg() with
appropriate role (based on PLOGI/PRLI bits). This allows
for a more cleaner rport->dd_data management as can be seen
with the simplified qla2xxx_slave_alloc() function.
