Since the code that was too ugly to live is upstream, we can use it now,
instead of rolling our own.

Installing 2.6.34 on a Power5/rn50 combo machine, X showed buggy sw rendering,
enabling tiling in the DDX fixed it. Investigation showed that a further /16
was needed in the untiled case on this chipset. Need further investigations
on what other chips this could affect, possibly rv100->rv280.

Plugged in FireMV with the rv250 on it, and the second crtc/dac didn't work,
we were reading/writing different registers than we were modifying in the code.

[IA64] Fix spinaphore down_spin()

Typo in down_spin() meant it only read the low 32 bits of the
"serve" value, instead of the full 64 bits. This results in the
system hanging when the values in ticket/serve get larger than
32-bits. A big enough system running the right test can hit this
in a just a few hours.

This patch adds some device ids.
The list of supported devices was extracted from realteks driver package.
(0x050d, 0x815F) and (0x0df6, 0x004b) are not in the official list of
supported devices and may not work correctly.
In case of problems with these, they should probably be removed from the list.

In commit bbfb5652, the spacing in the definitions of eqMacAddr and cpMacAddr
in drivers/staging/rtl8187se/r8180_core.c were changed to conform to kernel
standards. These definitions were duplicates of lines found in
drivers/staging/rtl8187se/ieee80211/dot11d.h. Once the change was made, the
following warnings were emitted:
CC [M] drivers/staging/rtl8187se/r8180_core.o
drivers/staging/rtl8187se/r8180_core.c:69:0: warning: "eqMacAddr" redefined

drivers/staging/rtl8187se/ieee80211/dot11d.h:40:0: note: this is the location of the previous definition
The fix is to keep only the difinition in the header file.

There is a possible race condition when hv_utils starts to load immediately
after hv_vmbus is loading - null pointer error could happen.
This patch added wait/completion to ensure all channels are ready before
vmbus loading completes. So another module won't have any uninitialized channel.

I received a report that AI streaming acquisitions do not work properly
for the adl_pci9111 driver when convert_src is TRIG_TIMER and
scan_begin_src is TRIG_FOLLOW (and scan_begin_arg is therefore 0). This
seems to be down to the incorrect setting of dev_private->scan_delay in
pci9111_ai_do_cmd(). Under the previously stated conditions,
dev_private->scan_delay ends up set to (unsigned int)-1, but it ought to
be set to 0. The function sets it to 0 initially, and it only makes
sense to change it if both convert_src and scan_begin_src are set to
TRIG_TIMER.
Note: 'scan_delay' is the number of unwanted scans to discard after each
valid scan. The hardware does not support 'scan' timing as such, just a
regularly paced conversion timer (with automatic channel switching
between conversions). The driver simulates a scan period that is some
(>1) multiple of the conversion period times the scan length
(chanlist_len samples) by reading chanlist_len samples and discarding
the next scan_delay times chanlist_len samples.

On fsg_unbind the common->fsg pointer was not NULLed if the
unbound fsg_dev instance was the current one. As an effect,
the incorrect pointer was preserved in all further operations
which caused do_set_interface to reference an invalid region.
This commit fixes this by raising an exception in fsg_bind
which will change the common->fsg pointer. This also requires
an wait queue so that the thread in fsg_bind can wait till the
worker thread handles the exception.
This commit removes also a config and new_config fields of
fsg_common as they are no longer needed since fsg can be
used to determine whether function is active or not.
Moreover, this commit removes possible race condition where
the fsg field was modified in both the worker thread and
form various other contexts. This is fixed by replacing
prev_fsg with new_fsg. At this point, fsg is assigned only
in worker thread.

The full speed descriptors were copied to the usb_function structure
in the fsg_bind_config function before call to the usb_ep_autoconfig.
The usb_ep_autoconfig was called in fsg_bind using the original
descriptors. In effect copied descriptors were not updated.
This patch changes the copy full speed descriptors after the call to
usb_op_autoconfig is performed. This way, copied full speed
descriptors have updated values.

Setting MUSB Burst Mode 3 automatically enables support for
lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified
length). There is no need to set these burst modes based on the
packet size. Also enable the burst mode for both mode1 and mode0.
This is a fix for buggy hardware - having the lower burst modes
enabled can potentially cause lockups of the DMA engine used in
OMAP2/3/4 chips.

Attempt to build MUSB driver with CONFIG_PM=y (e.g. in the OTG mode) on DaVinci
results in these link errors:
drivers/built-in.o: In function `musb_restore_context':
led-triggers.c:(.text+0x714d8): undefined reference to

drivers/built-in.o: In function `musb_save_context':
led-triggers.c:(.text+0x71788): undefined reference to
`musb_platform_save_context'
This turned out to be caused by commit 9957dd97ec5e98dd334f87ade1d9a0b24d1f86eb
(usb: musb: Fix compile error for omaps for musb_hdrc). Revert it, taking into
account the rename of CONFIG_ARCH_OMAP34XX into CONFIG_ARCH_OMAP3 (which that
commit fixed in a completely inappropriate way) and the recent addition of
OMAP4 support.

Commit 1c25fda4a09e8229800979986ef399401053b46e (usb: musb: handle irqs in the

filter for calling musb_stage0_irq(), so now disconnect and suspend interrupts
are effectively ignored...

This patch (as1403) is a partial reversion of an earlier change
(commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

Stanse found that sleep is called inside atomic context created by
lock_printer_io spinlock in several functions. It's used in process
context only and some functions sleep inside its critical section. As
this is not allowed for spinlocks, switch it to mutex.

Stanse found that isp1362_sw_reset tries to take a isp1362_hcd->lock,
but it is already held in isp1362_hc_stop. Avoid that by introducing
__isp1362_sw_reset which doesn't take the lock and call it from
isp1362_hc_stop. isp1362_sw_reset is then as simple as lock --
__isp1362_sw_reset -- unlock.

This patch corrects a problem with the merge of a previous
patch to add the CONTEC identifier.
I believe the merge problem occurred with the commit:
dee5658b482e9e2ac7d6205dc876fc11d4008138
Originally I submitted a patch and then they asked me to order the IDs
and resubmit, so did I. But unfortunately in the end somehow both
patches were merged.

As a part of aligning the ISR code for MUSB with the specs, the
ISR code was re-written.

With this the suspend interrupt came accidently under CONFIG_USB_MUSB_HDRC_HCD.
The fix brings suspend interrupt handling outside
CONFIG_USB_MUSB_HDRC_HCD.

Commit 6c12db90f19727c76990e7f4801c67a148b30111 introduced a bug for
control transfers. The patch was supposed to change when the link TRBs at
the end of each ring segment were given to the hardware. If a transfer
descriptor (TD) ended just before the link TRB, the code wouldn't give
back the link TRB to the hardware; instead it would be given back in
prepare_ring() just before the next TD was enqueued at the top of the
ring.
Unfortunately, the code relied on checking the chain bit of the TRB to
determine whether the TD ended just before the link TRB. It assumed that
the ring enqueuing code would call prepare_ring() before enqueuing the
next TD. However, control transfers are made of multiple TDs, and
prepare_ring() is only called once before enqueuing two or three TDs.
If the first or second TD of the control transfer ended just before the
link TRB, then the code in inc_enq() would not move the enqueue pointer
past the link TRB, and the link TRB would get overwritten. This would
cause the xHCI driver to start writing to memory past the ring segment,
and eventually the system would crash or hang.
The fix is to add a flag to inc_enq() that says whether the caller will
enqueue more TDs before calling prepare_ring(). If the chain bit is
cleared (meaning this is the last TRB in a TD), and the caller will not
enqueue more TDs, then we defer giving back the link TRB.

During __gfs_do_config() some invalid pointers may be left
in usb_configuration::interfaces array from previous calls
to the __gfs_do_config() for the same configuration. This
will always happen if an user space function which has
a fewer then the last user space function registers itself.
Composite's set_config() function that a pointer after the
last interface in usb_configuration::interface is NULL
unless the array is full.
This patch makes the __gfs_do_config() make sure that if the
usb_configuration::interface is not full then a pointer
after the last interface is NULL.

Implementing this function both fixes the build when CONFIG_CONSOLE_POLL
