Commit 81933046ef2a615031c46171013bde2c5225ee69 ('mtd: Fix handling of
mtdname in txx9ndfmc.c') introduced a potential memory leak. The
'mtdname' member of the private data structure is now allocated
separately, but was not freed on certain error paths.
Fix that, and make things simpler by _always_ allocating it separately
so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'...
which gets ugly now that we're doing it more than once, and more likely
that we'll get it wrong some time.

and failure to write the clean marker,
moves the offending erase block to erasing list before calling
jffs2_erase_failed(). This is bad as jffs2_erase_failed() will
also move the block to the bad_list, but is now moving the

The following patch fixes:
- re-initialization of host->col_addr which is used as byte index
between the successive READID flash commands.
- compile error when CONFIG_PM is enabled
- pass on the error code from clk_get()
- return -ENOMEM in case of failed ioremap()
- pass on the return value of platform_driver_probe() directly
- remove excessive printk
- let command line partition table parsing with mxc_nand name.
The cmd_line parsing is done via <mtd-id> name that differs
from mxc_nand by default and looks like "NAND 256MiB 1,8V 8-bit"

This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect. The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.
This problem shows up with Keyspan devices and it might affect others
as well.
When the attach method returns a positive value, the patch sets
num_ports to 0. This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

The option driver (and presumably others) allocates several URBs when it
opens and tries to free them when it closes. The isp1760_urb_dequeue
function gets called, but the packet being dequeued is not necessarily at
the
front of one of the 32 queues. If not, the isp1760_urb_done function doesn't
get called for the URB and the process trying to free it hangs forever on a
wait_queue. This patch does two things. If the URB being dequeued has others
queued behind it, it re-queues them. And it searches the queues looking for
the URB being dequeued rather than just looking at the one at the front of
the queue.

The svcrdma module was incorrectly unmapping the RPCRDMA header page.
On IBM pserver systems this causes a resource leak that results in
running out of bus address space (10 cthon iterations will reproduce it).
The code was mapping the full page but only unmapping the actual header
length. The fix is to only map the header length.
I also cleaned up the use of ib_dma_map_page() calls since the unmap
logic always uses ib_dma_unmap_single(). I made these symmetrical.

Commit 'Short write in nfsd becomes a full write to the client'
(31dec2538e45e9fff2007ea1f4c6bae9f78db724) broken the sync write.
With the following commands to reproduce:
$ mount -t nfs -o sync 192.168.0.21:/nfsroot /mnt
$ cd /mnt
$ echo aaaa > temp.txt
Then nfs client is hung up.
In SYNC mode the server alaways return the write count 0 to the
client. This is because the value of host_err in nfsd_vfs_write()
will be overwrite in SYNC mode by 'host_err=nfsd_sync(file);',
and then we return host_err(which is now 0) as write count.
This patch fixed the problem.

When a GEM object is evicted from the GTT we set it to the CPU domain,
as it might get swapped in and out or ever mmapped regularly. If the
object is mmapped through the GTT it can still get evicted in this way
by other objects requiring GTT space. When the GTT mapping is touched
again we fault it back into the GTT, but fail to set it back to the
GTT domain. This means we fail to flush any cached CPU writes to the
pages backing the object which will then happen "eventually", typically
after we write to the page through the uncached GTT mapping.
[anholt: Note that userland does do a set_domain(GTT, GTT) when starting
to access the GTT mapping. That covers getting the existing mapping of the
object synchronized if it's bound to the GTT. But set_domain(GTT, GTT)
doesn't do anything if the object is currently unbound. This fix covers the
transition to being bound for GTT mapping.]

On the 865, but not the 855, the clflush we do appears to not actually make
it out to the hardware all the time. An easy way to safely reproduce was
X -retro, which would show that some of the blits involved in drawing the
lovely root weave didn't make it out to the hardware. Those blits are 32
bytes each, and 1-2 would be missing at various points around the screen.
Other experimentation (doing more clflush, doing more AGP chipset flush,
poking at some more device registers to maybe trigger more flushing) didn't
help. krh came up with the wbinvd as a way to successfully get all those
blits to appear.

The pitch field is an exponent on pre-965, so we were rejecting buffers
on 8xx that we shouldn't have. 915 got lucky in that the largest legal
value happened to match (8KB / 512 = 0x10), but 8xx has a smaller tile width.
Additionally, we programmed that bad value into the register on 8xx, so the
only pitch that would work correctly was 4096 (512-1023 pixels), while others
would probably give bad rendering or hangs.

A docking mic control is shown by default. The Compaq Presario
CQ60 laptop has no docking connector, so designate it as a
CXT5051_HP model.
This makes the phantom mixer slider disappear.

The PCM hw_ptr jiffies check results sometimes in problems when a
hardware doesn't give smooth hw_ptr updates. So far, au88x0 and some
other drivers appear not working due to this strict check.
However, this check is a nice debug tool, and the capability should be
still kept.
Hence, we disable this check now as default unless the user enables it
by setting the xrun_debug mode to the specific stream via a proc file.

The hw_ptr_jiffies has to be reset properly to avoid the invalid
check of jiffies delta in snd_pcm_update_hw_ptr*() functions.
Especailly this patch fixes the bogus jiffies check after the puase
and resume.
This patch is a modified version of the original patch by Jaroslav.

Kernel 2.6.18 broke the MotU Fastlane, which uses duplicate endpoint
numbers in a manner that is not only illegal but also confuses the
kernel's endpoint descriptor caching mechanism. To work around this, we
have to add a separate usb_set_interface() call to guide the USB core to
the correct descriptors.
