Introduce some sbus_dma routines similar to the
ebus_dma stuff to make the code look nearly the same
for both cases.
Thanks to Christopher for testing.

Patch from Lennert Buytenhek
Since we have to use XCB=101 instead of XCB=000 on the ixp2400 to
prevent it from regularly falling over, and since we have to deal with
manual write buffer flushing because of that, we might as well use
XCB=101 on all ixp2000 platforms since it's faster than XCB=000.

Patch from Lennert Buytenhek
nwfpe extended precision emulation used to be broken on big-endian
and was therefore disabled. This patch fixes nwfpe so that it copies
extended precision floats to/from userspace in the proper word order
(similar to patch #2046, see the description of that patch for an
explanation) and reenables the Kconfig option.

Patch from Lennert Buytenhek
The routine that nwfpe uses for converting floats/doubles to
extended precision fails to zero two bytes of kernel stack. This
is not immediately obvious, as the floatx80 structure has 16 bits
of implicit padding (by design.) These two bytes are copied to
userspace when an stfe is emulated, causing a possible info leak.
Make the padding explicit and zero it out in the relevant places.

Via reading the code, my understanding is that powernow-k8 uses
preempt_disable to ensure that driver->target doesn't migrate across cpus
whilst it's accessing per processor registers, however set_cpus_allowed
will provide this for us. Additionally, remove schedule() calls from
set_cpus_allowed as set_cpus_allowed ensures that you're executing on the
target processor on return.

for stats.
The problem is in the ondemand governor, there is a periodic measurement
of the CPU usage. This CPU usage is updated by the scheduler after every
tick (basically, by adding 1 either to "idle" or to "user" or to
"system"). So if the frequency of the governor is too high, the stat
will be meaningless (as mostly no number have changed).
So this patch checks that the measurements are separated by at least 10
ticks. It means that by default, stats will have about 5% error (20
ticks). Of course those numbers can be argued but, IMHO, they look sane.
The patch also includes a small clean-up to check more explictly the
result of the conversion from ns to µs being null.
Let's note that (on x86) this has never been really needed before 2.6.13
because HZ was always 1000. Now that HZ can be 100, some CPU might be
affected by this problem. For instance when HZ=100, the centrino ,which
has a 10µs transition latency, would lead to the governor allowing to
read stats every tick (10ms)!

The mips_rtc_lock is no longer needed because RTC operations should be
protected already by other mechanism. (rtc_lock, local_irq_save, etc.)
Also, locking whole rtc_get_time/rtc_set_time should be avoided while
some RTC routines might take very long time (a few seconds).
