Currently, ide_cmd_ioctl when invoked for setting DMA transfer mode calls
ide_find_dma_mode with requested mode as XFER_UDMA_6. This prevents setting DMA
mode to any other value than the default (maximum) supported by the device (or
UDMA6, if supported) irrespective of the actual requested transfer mode and
returns error.
For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default
transfer mode gives following error:
# ./hdparm -d1 -Xudma2 /dev/hda
/dev/hda:hda: UDMA/66 mode selected
setting using_dma to 1 (on)
hda: UDMA/66 mode selected
setting xfermode to 66 (UltraDMA mode2)
HDIO_DRIVE_CMD(setxfermode) failed: Invalid argument
using_dma = 1 (on)
This patch fixes the issue.

Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend
and resume process, but don't clean up after themselves. So manually
clear all DMA channels when resuming since no DMA could have been running
at this point in time. Now Linux should be able to work regardless of any
laziness on the part of the on-chip ROM or boot loader.

There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.
This breaks module loading on, e.g. a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.
Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.
This fixes a serious regression, introduced by commit
e675abafcc, "thinkpad-acpi: be more strict
when detecting a ThinkPad".

SMB writes are sent with a starting offset and length. When the server
supports the newer SMB trans2 posix open (rather than using the SMB
NTCreateX) a file can be opened with SMB_O_APPEND flag, and for that
case Samba server assumes that the offset sent in SMBWriteX is unneeded
since the write should go to the end of the file - which can cause
problems if the write was cached (since the beginning part of a
page could be written twice by the client mm). Jeff suggested that
masking the flag on posix open on the client is easiest for the time
being. Note that recent Samba server also had an unrelated problem with
SMB NTCreateX and append (see samba bugzilla bug number 6898) which
should not affect current Linux clients (unless cifs Unix Extensions
are disabled).
The cifs client did not send the O_APPEND flag on posix open
before 2.6.29 so the fix is unneeded on early kernels.
In the future, for the non-cached case (O_DIRECT, and forcedirectio mounts)
it would be possible and useful to send O_APPEND on posix open (for Windows
case: FILE_APPEND_DATA but not FILE_WRITE_DATA on SMB NTCreateX) but for
cached writes although the vfs sets the offset to end of file it
may fragment a write across pages - so we can't send O_APPEND on
open (could result in sending part of a page twice).

Signed-off-by: David S. Miller <davem@davemloft.net>
RSC and LOM devices have fixed speed settings.
We already had some code to match and handle "rsc" named devices on
E250 systems, but we also have to handle 'rsc-console', 'rsc-control',
and 'lom-console'.
Also, in order to get this right regardless of what 'output-device'
happens to be, explicitly pass the UART device node pointer to this
routine.
Signed-off-by: David S. Miller <davem@davemloft.net>
This tells the logic to ignore the line match when deciding whether the
device is the OpenFirmware specified console device or not.
This is going to be used in the SU driver for rsc-console detection.
There is probably a better way to handle this, but this is the least
intrusive solution for now which we can validate won't break any other
cases.
