sil24 softreset timeout was > 100ms (100 loops with msleep(1)), which
turned out to be too short for some devices (ASI ARAID99 2000). This
patch converts sil24 softreset waiting loop to use proper timeout
condition and lengthen the timeout to ATA_TMOUT_BOOT secs and check
interval to 100ms. Chisato Yamauchi discovered the problem and
supplied initial patch.

sata_sil24 softreset routine used to check sata_dev_present() after
SRST is complete in the hope that SRST may do some good even when
SStatus reports no device. This is okay as long as SRST timeout is
short (> 100ms in the current code) but it seems that not all SATA
devices are happy with short SRST timeout.
This patch makes softreset exit early without performing actual SRST
if SStatus reports no device in preparation for lengthening SRST
timeout.

ata_bus_probe() didn't initialize classes[] properly with
ATA_DEV_UNKNOWN. As ->probe_reset() is allowed to leave @classes
alone when no device is present, this results in garbage class values.
ATM, the only affected driver is ata_piix.

Preceding xfer_mask changes make the following functions unused.
ata_pio_modes(), base_from_shift(), ata_pr_blacklisted(), fgb()
Kill them. Also, as xfer_mode_str[] is now only used by
ata_mode_string(), move it into the function.

Make pio_task and atapi_packet_task use port_task.
atapi_packet_task() is moved upward such that it's right after
ata_pio_task(). This position is more natural and makes adding

Implement port_task. LLDD's can schedule a function to be executed

This patch fixes an error in the dl2k driver's DMA mapping/unmapping.
The adapter uses the upper 16bits of the DMA address for the buffer
size. However, this is not masked off when referencing the DMA
address, and can lead to errors by trying to free a DMA address out of
range.
Thanks,
Jon

For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT
instead of one of the NETDEV_TX_* error codes. In fact, it frees up
the SKB before returning this. This makes the queueing layer think
the packet should be requeued and subsequently we corrupt a freed
object.

The patch '[PATCH] RCU signal handling' [1] added an export for
__put_task_struct_cb, a put_task_struct helper newly introduced in that
patch. But the put_task_struct couldn't be used modular previously as
__put_task_struct wasn't exported. There are not callers of it in modular
code, and it shouldn't be exported because we don't want drivers to hold
references to task_structs.
This patch removes the export and folds __put_task_struct into
__put_task_struct_cb as there's no other caller.

Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all
agree are very much wrong. These files shouldn't become part of the ABI by
the 2.6.16 release, so I rather have this minimal patch merged to disable
them for now, the real fix can then come during the 2.6.17 devel window.

One can do "chattr +j" on a file to change its journalling mode. Fix
writeback mode with "nobh" handling for it.
Even though, we mount ext3 filesystem in writeback mode with "nobh" option,
some one can do "chattr +j" on a single file to force it to do journalled
mode. In order to do journaling, ext3_block_truncate_page() need to
fallback to default case of creating buffers and adding them to transaction
etc.

This patch fixes illegal __GFP_FS allocation inside ext3 transaction in
ext3_symlink(). Such allocation may re-enter ext3 code from
try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal
handle in task_struct and, hence, is not reentrable.
This bug led to "Assertion failure in journal_dirty_metadata()" messages.
