Fill devno[cid] from request instead of sc_request->sr_request since
sc_request is passed in as NULL now.

Somewhere along the line, indentation on this file went mental.

Most work done by Paul Gortmaker. More work needed.

Marc Singer noticed some BIOSen on the AMD Elan
alias the cpu frequency registers in a place that some
drivers probe during bootup. Result - changed CPU speed
after booting.

The fix is to unmap the alias.

Marc put a patch forward for 2.2, this one is cooked up
by me, but is currently untested but functionally equivalent.

(is already in drivers/char/agp/Config.help)

The smp_call_function() does the check on the local cpu for us.

Some host bridges that use the indirect (addr and data registers)
method of access have a field that needs to be set to 0 for accesses
to the primary bus and 1 for accesses to subordinate buses.  This
change allows for that.

We do this with an out-of-line assembler function, __div64_32,
for the case when the high word of the dividend is non-zero.

We can't now use make -C in conjunction with Rules.make because
the rules for making .o files break if we do.  This updates the
boot wrapper Makefiles so that we don't use make -C, instead we
use call descend plus various other new features in Rules.make.

Previously we had xchg_u32 both inline in system.h and out-of-line
in arch/ppc/kernel/misc.S, and it was exported for good measure.
We only need the inline definition.

NOTE: swim_iop (and swim3) are broken for situations when several drives
are present.  Failure mode is rather amusing - the thing does a sort of
load-balancing and if you have two drives even requests end up sent to
the first and odd - to the second ;-) Had been there since they went
into the tree.  Swim3 mentions that support of multiple drives needs to
be fixed, swim_iop (derived from it) had lost even that warning.
