this is a new waiting helper safe even if we are left on a waitqueue.
This version addresses Alan's concerns about ifdefs. Please apply.

  - add delay helper that is safe even if we are still on another waitqueue

This resolves a FIXME by adding module parameters that can
be used to provide stable (vs random) addresses, and gets
rid of a runtime error from obsolete module parameter usage
in the RNDIS code.

The stable ethernet addresses are nice to hosts, which will
normally want to save them away in config databases.  For
example, without stable addresses Windows XP will end up
recording quite a lot of RNDIS devices.

This should fix the problem David Meggy found, where RNDIS was setting
the OID_GEN_CURRENT_PACKET_FILTER state incorrectly.  It's the same
issue Andrew Morton noticed a while back, for that matter, but with
more than just a "now compiles on 64 bit" fix.

Basically the code needs to interpret 32 bits provided in the request
from the (Windows) host, rather than 8 bits of other memory that's got
some irrelevant value.

The fix is just to save the 32 bits.  I did the same thing with the
CDC Ethernet filter, which should eventually be used the same way:  to
limit what packets get sent to the host.  Also defined a couple more
of the CDC requests.

I made a mistake fixing that driver. Here's the fix. Please apply soon.

  - fix race condition leading to busy waiting

Here are some MSEC_TO_JIFFIES() fixes missed by whoever did it,
plus a minor fix to grab root_hub->serialize() during OHCI
suspend.  (I forgot to cut/paste those lines from resume.)

drivers/scsi/hosts.h is obsolete, <scsi/scsi_host.h> is the prefered header
nowadays. (hosts.h is just a 1 line wrapper to include it for now anyway)

No usb serial devices, just compiled in and the system has a USB controller.

ata_scsi_translate() sets this flag for all ATA->SCSI translated
commands, so it need not be done in atapi_xlat().  The now-removed
use in atapi_xlat() was also inconsistent WRT PIO versus DMA.

DMADIR bit is necessary for some PATA->SATA bridges.  These
bridges require the OS driver to specify the data xfer direction,
for PACKET (a.k.a. scsi) commands.

A reliable DMADIR detection method hasn't yet been developed,
and ATAPI is still a WIP, so DMADIR is enabled with an ifdef for
now.

Since all boards specify base_baud, the code to default base_baud to
the architecture-defined BASE_BAUD is redundant.  Also, defaulting
to the architecture-defined BASE_BAUD is wrong since the UARTs on a
serial PCI card will be clocked at the same rate no matter what the
architecture of the host machine.

This eliminates the last SWI user from the kernel - now all SWI calls
will only come from userspace.  More importantly, this also allows us
to empty the kernel stack when starting userspace programs from
kernelspace, thereby ensuring that the user registers always appear
at the top of the kernel stack.

This moves a bunch of EXPORT_SYMBOL() statements from armksyms.c
into the file which defines the function/variable such that the
exports are localised.

This also means we can get rid of the ugly __xxx_to_xxx__is_a_macro
in include/asm-arm/arch-*/memory.h

No more users of the autoirq_xxx() API existed, so this file is not
only unused, it isn't even listed in any makefiles.

This fixes the gfp_mask setting on the quota inode.

This patch makes the b44-after-bcm4400 scenario work for
me. What was happening is that the broadcom driver sets a "power off MAC"
bit, and we didn't remove that when initializing the chip.
Also added some (a bit ugly, I know  ) logic to clear up the address
filter stuff, which is what recent broadcom drivers do...

It's easier to do it this way, than polling, at the moment.

Also, fix a test in ata_scsi_translate that was incorrectly
erroring-out non-data commands.

* now that ATAPI is close to working, making ATAPI DMA interrupts
  in ata_host_intr
* remove unnecessary space character in printk() output (oh, the horror)

This skips the GP-loading function prologue (two instructions: 8 bytes)
on BRSGP linkage correctly, fixing an oops on alpha while loading the
aic7xxx driver.

mapped memory.

A regular "memset()" may be using cache control
instructions etc, which is not appropriate for
memory-mapped IO.

This also fixes a warning.

Patch from Robin Farine

Fix the xscale cache handling routines that were invalidating a D 
cache line instead of draining the write & fill buffer as intended.

Patch from Catalin Marinas

Unlike the v5 architecture, the ARM1136 requires that BIT4 is 0 in
the first level page descriptor (ARM1136 TRM, page 6-39). It works
at the moment but it might break future v6 cores.

Patch from Catalin Marinas

The v6_dma_invalidate_range - the "mcr" instruction for draining

the write buffer requires r0 == 0. A "cmp" instruction for

testing the end address is missing in the v6_dma_flush_range

function.

Patch from Catalin Marinas

The _raw_write_(try)lock functions in include/asm-arm/spinlock.h

should use the early clobber modifier (&) for the "tmp" register.

A newer compiler (gcc-3.4.0) generates an "strexeq %0, %1, [%2]"

instruction where %0 is the same as %2, which is illegal.

Patch from Catalin Marinas

In the blockops_check() function, cache_type is uninitialised

because an "mcr" instruction is used instead of "mrc".

Remove unused 'done_late' arg to ata_qc_complete(), which was never
useful in 2.4, and never used at all in 2.6.

This allows us to eliminate the same arg from ata_dma_complete(),
and also make it more correct by passing the command rather than
the ATA port structure as arg0.
