[MIPS] DECstation: Optimised early printk()
This is an optimised implementation of early printk() for the DECstation.
After the recent conversion to a MIPS-specific generic routine using a
character-by-character output the performance dropped significantly.
This change reverts to the previous speed -- even at 9600 bps of the
serial console the difference is visible with a naked eye; I presume for a
framebuffer it is even worse (it may depend on exactly which one is used
though).
Additionally the change includes a fix for a problem that the old
implementation had -- the format used would not actually limit the length
of the string output. This new implementation uses a local buffer to deal
with it -- even with this additional copying it is much faster than the
generic function.
Plus this driver is registered much earlier than the generic one,
allowing one to see critical messages, such as one about an incorrect CPU
setting used, that are produced beforehand. :-)

[MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbols
The current implementation of __pa() for 64-bits kernels with 32-bits
symbols is broken. In this configuration, we need 2 values for
PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space.
When the value in CKSEG0 space is used, it doesn't take into account
of PHYS_OFFSET. Even worse we can't redefine this value.
The patch restores CPHYSADDR() but in __pa()'s implementation because
it removes the need of 2 PAGE_OFFSET.
OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So
this patch assumes there's no need to deal with such kernel in 64-bits

ieee1394: remove old isochronous ABI
Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"
from Adrian Bunk, November 20 2006.
This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx. That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.
Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso
interface has never been implemented in pcilynx, pcilynx is now no
longer useful for isochronous applications.
raw1394 will still handle the request types but will complete the
requests with errors that indicate API version conflicts.

sched: more agressive idle balancing
the Linux scheduler is starving a number of workloads. So default
to more agressive idle-balancing. This hurts lmbench context-switching
numbers (which was the main reason we sucked at idle-balancing for
such a long time) but the lmbench numbers are fine once the system is
minimally utilized.

do not set softirqs to nice +19. _If_ for whatever reason
we missed to process some high-prio softirq and woke up
ksoftirqd, we should give it a fair chance to actually
get some work done, even if the system is under load.
