o Change the blk_dump_rq_flags() a bit

o Use rq->bio as an indication of ->bio is valid or not, instead of
  checking REQ_PC. Now we can have a bio on a REQ_BLOCK_PC as well.

o Don't print eio error in end_that_request_first(), if REQ_QUIET is set.

o debug check for valid bio in end_that_request_first()

o Add blk_pc_request() check REQ_BLOCK_PC, similar to blk_fs_request()

Remove the calling of scsi_cmd_ioctl() from ide-cd.  Put it in the
uniform cdrom layer, this also makes SCSI SG_IO work.

Make SCSI layer understand REQ_BLOCK_PC requests

A recent change that went into BK-2.5 removed the next member of the
scsi host and replaced it with lists, which is cool, but this broke a
few common drivers.

Here is the fix for aic7xxx_old.

Recent scsi host changes broke sym2, it iterates over the scsi host list
itself. This patch changes sym2 to use scsi_host_hn_get() to find a scsi
host from its hostno.

This patch fixes a bug in my AFS client in which a put of an outstanding call
was missing in the unmount cleanup code. This occasionally resulted in the AFS
module becoming unremovable.

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.
