- Use u_long or long rather than paddr_t for ARCBIOS function prototypes
as per the ARC specification. They are actually 64bit on MIPS64 based
machines and our paddr_t is not equal to pointer size.

Catch up to struct consdev changes.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Make the field names in the system ID structure match the spec.

Initial pass a ARC BIOS code that can be shared between the sgimips

Avoid use of CALLFRAME_S0 on calling ARC BIOS functions.

On O32 and O64, 0(sp) could be clobbered by callee functions
to save argument a0, so we can't use it to save caller registers.
Use CALLFRAME_SP instead because a frame pointer is not used here.
Maybe all other references of CALLFRAME_S0 might also be problematic
on O32. Discussed with soda@.

Explicitly use MIPS_CURLWP macro. No binary change.

Don't forget to save MIPS_CURLWP (t8) register before restoring it.

Maybe harmless because the only ARC BIOS function that takes
more than four arguments is currently unused.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use

I have not built every extant kernel so I have probably broken at
