* Use pio == 255 == "auto-tune" in scc_config_drive_for_dma() instead of
forcing PIO4 on PIO fallback. Fix comment while at it.
* Rename scc_tuneproc() to scc_tune_pio() and add scc_tuneproc() wrapper.
Move finding of the best PIO mode and setting of transfer mode on the device
to the new wrapper.
* Fix scc_tune_chipset() to tune PIO modes. Do a small cleanup while at it.

* Fix cs5535_tuneproc() to pass PIO transfer mode value instead of PIO mode
number to cs5535_set_speed() (fixes random PIO timings being programmed
and a possible OOPS). Do a little cleanup while at it.
* Fix cs5535_set_speed() to check if the mate device is present (fixes PIO0
taskfile timings being used if there is no other device on the cable).
* Use cs5535_tuneproc() in cs5535_dma_check(). The old code had the same
issue as cs5535_tuneproc() and add additionally caused 0x00-0x04 transfer
mode values (== default PIO, default PIO w/ IORDY + two invalid values)
being set on the device instead of values 0x08-0x0c (XFER_PIO_[0,4]).

Is this a bug? In original verison memset cleared sizeof(state) bytes
instead of sizeof(*state). If it was intentional then this patch is invalid.
If not intentional -> valid :) Please review.

As found by the Coverity checker, and reported by Adrian Bunk, this
fixes a overrun error in the CS5535 IDE driver. Somebody got a little
excited with the if() statement - the CS5535 only supports UDMA 0-4.
Bart:
Not a bug per se since the upper layer will never feed this function
with speed > XFER_UDMA_4 (thanks to ->ultra_mask being set to 0x1f).

Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they
are drifting then we have not synchronized the ITC values, nor are we doing
the jitter compensation (useless since drift may increase the differentials
arbitrarily).
Without this patch it is possible that the ITC clock becomes selected as
the system clock on systems with drifty ITCs which will result in
nanosleep hanging.
One can still select the itc clock manually on such systems via
clocksource=itc
(Produces nice hangs on SGI Altix.)

If the sn2_rtc clock is present then it is a must have since sn2_rtc
provides a synchronized time source on Altix systems. So elevate
the priority to 450. Otherwise the ITC would take precendence. Altix
systems currently do not boot because the ITC clocksource is broken. It
seems to assume that ITCs are synchronized and as a result nanosleep
hangs (may be fixed in a different patch).
While we are at it: Remove the sn2_mc definition. The sn2_rtc has a fixed
address. No point in reading the address from memory. Removing it avoids
touching one cacheline.

* Fix MWDMA timings setup in sis_old_set_dmamode() and sis_66_set_dmamode().
The old timings were overclocked (even worse behavior than sis5513 IDE driver
which depends on BIOS to program correct timings), the new timings are taken
from the datasheet (they match timings from ATA spec).
* Fix UDMA timings setup in sis_old_set_dmamode().
Misplaced pci_write_config_word() call resulted in UDMA timings never
being set.
* Fix comments for sis_133_early_set_dmamode() and sis_133_set_dmamode():
- only the former function handles early SiS 961 bridges
- both functions lack MWDMA timings setup
* Fix typos in sis_100_set_piomode() and sis_133_set_piomode() comments.
* Bump driver version.

Alexey Dobriyan noticed that the new WARN_ON() semantics that were
introduced by commit 684f978347deb42d180373ac4c427f82ef963171 (to also
return the value to be warned on) didn't compile when given a bitfield,
because the typeof doesn't work for bitfields.
So instead of the typeof trick, use an "int" variable together with a
"!!(x)" expression, as suggested by Al Viro.
To make matters more interesting, Paul Mackerras points out that that is
sub-optimal on Power, but the old asm-coded comparison seems to be buggy
anyway on 32-bit Power if the conditional was 64-bit, so I think there
are more problems there.
Regardless, the new WARN_ON() semantics may have been a bad idea. But
this at least avoids the more serious complications.

m48t59->irq = NO_IRQ;
And thus it will make the m48t59_rtc_probe() is failed when the driver is

This updates some error reporting paths in SPI device setup:
- Move validation logic for SPI chipselects to spi_new_device(),
which is where it should always have been.
- In spi_new_device(), emit error messages if the device can't
be created. This is LOTS better than a silent failure; though
eventually, the calling convention should probably change to
use the <linux/err.h> conventions.
- Includes one previously-missing check: SPI masters must always
have at least one chipselect, even for dedicated busses which
always keep it selected!
It also adds a FIXME (IDR for dynamic ID allocation) so the issue doesn't live
purely in my mailbox.

This patch fix weird behaviour of UDF mounting procedure. To get UID
changed (for now) we have to type
mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point
and specifying two uid at once is strange a bit. So with the patch we are
able to mount without additional 'uid=ignore' option. The same for GID
option is done.
This patch will not break current mount scheme (with two option).

Coverity spotted what looks like a real possible case of using a variable
after it has been freed. The problem is in
kernel/relay.c::relay_open_buf()
If the code hits "goto free_buf;" it ends up in this code :
free_buf:
relay_destroy_buf(buf); <--- calls kfree() on 'buf'.
free_name:
kfree(tmpname);
end:
return buf; <-- use after free of 'buf'.
I read through the callers and they all handle a NULL return from this
function as an error (and hitting the 'free_buf' label only happens on
failure to chan->cb->create_buf_file(), so that looks like a clear error to
me).
The patch simply sets 'buf' to NULL after the call to
relay_destroy_buf(buf); - as far as I can see that should take care of the
problem.
The patch also corrects a reference to a documentation file while
I was at it.
Note from Mathieu: the documentation reference change should have been
done in a separate patch, but I guess no one will really care.
