A recent patch for DMA cache maintenance on ARM11MPCore added a write for ownership trick to the v6_dma_inv_range() function. Such operation destroys data already present in the buffer. However, this function is used with with dma_sync_single_for_device() which is supposed to preserve the existing data transfered into the buffer. This patch adds a combination of read/write for ownership to preserve the original data. Reported-by:

futex_find_get_task is currently used (through lookup_pi_state) from two contexts, futex_requeue and futex_lock_pi_atomic. None of the paths looks it needs the credentials check, though. Different (e)uids shouldn't matter at all because the only thing that is important for shared futex is the accessibility of the shared memory. The credentail check results in glibc assert failure or process hang (if glibc is compiled without assert support) for shared robust pthread mutex with priority inheritance if a process tries to lock already held lock owned by a process with a different euid: pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed. The problem is that futex_lock_pi_atomic which is called when we try to lock already held lock checks the current holder (tid is stored in the futex value) to get the PI state. It uses lookup_pi_state which in turn gets task struct from futex_find_get_task. ESRCH is returned either when the task is not found or if credentials check fails. futex_lock_pi_atomic simply returns if it gets ESRCH. glibc code, however, doesn't expect that robust lock returns with ESRCH because it should get either success or owner died.

(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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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 `musb_platform_restore_context' 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 9957dd97 (usb: musb: Fix compile error for omaps for musb_hdrc).

This patch (as1403) is a partial reversion of an earlier change (commit 5f677f1d "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. Signed-off-by:

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. Signed-off-by:
