2011-02-19ALSA: HDA: Do not announce false surround in Conexant autoDavid Henningsson1-1/+1
Without this patch, one line-out and one speaker and Conexant's auto parser would announce (non-working) surround capabilities. BugLink: http://bugs.launchpad.net/bugs/721126 Cc: [email protected] Signed-off-by: David Henningsson <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
2011-02-19ALSA: HDA: Conexant auto: Handle multiple connections to ADC nodeDavid Henningsson1-13/+48
Conexant 20641 has several inputs to its ADC node, with one selector and individual amps for all inputs. This patch adds support in the Conexant auto parser to handle that case. It also means that the pin node's volume is being renamed to "Boost" to avoid name clash with the new volume controls on the ADC node.

2011-02-19ARM: 6743/1: errata: interrupted ICALLUIS may prevent completion of ↵Will Deacon2-0/+16
broadcasted operation On versions of the Cortex-A9 prior to r3p0, an interrupted ICIALLUIS operation may prevent the completion of a following broadcasted operation if the second operation is received by a CPU before the ICIALLUIS has completed, potentially leading to corrupted entries in the cache or TLB. This workaround sets a bit in the diagnostic register of the Cortex-A9, causing CP15 maintenance operations to be uninterruptible.

2011-02-19ARM: 6742/1: pmu: avoid setting IRQ affinity on UP systemsWill Deacon1-8/+14
Now that we can execute a CONFIG_SMP kernel on a uniprocessor system, extra care has to be taken in the PMU IRQ affinity setting code to ensure that we don't always fail to initialise. This patch changes the CPU PMU initialisation code so that when we only have a single IRQ, whose affinity can not be changed at the controller, we report success (0) rather than -EINVAL.

2011-02-19ARM: 6741/1: errata: pl310 cache sync operation may be faultySrinidhi Kasagar3-0/+22
The effect of cache sync operation is to drain the store buffer and wait for all internal buffers to be empty. In normal conditions, store buffer is able to merge the normal memory writes within its 32-byte data buffers. Due to this erratum present in r3p0, the effect of cache sync operation on the store buffer still remains when the operation completes. This means that the store buffer is always asked to drain and this prevents it from merging any further writes. This can severely affect performance on the write traffic esp. on Normal memory NC one. The proposed workaround is to replace the normal offset of cache sync operation(0x730) by another offset targeting an unmapped PL310 register 0x740.

After 2.6.34 changes, __pxa2xx_drv_pcmcia_probe() was replaced by sa1111_pcmcia_add(). That unfortunately means that configure_sockets() is not called, leading to MECR not being set properly, leading to strange crashes. Tested on pxa255+sa1111, I do not have lubbock board nearby.

2011-02-19drivers/char/pcmcia/ipwireless/main.c: Convert release_resource to ↵Julia Lawall1-20/+32
release_region/release_mem_region Request_region should be used with release_region, not release_resource. This patch contains a number of changes, related to calls to request_region, request_mem_region, and the associated error handling code. 1. For the call to request_region, the variable io_resource storing the result is dropped. The call to release_resource at the end of the function is changed to a call to release_region with the first two arguments of request_region as its arguments. The same call to release_region is also added to release_ipwireless. 2. The first call to request_mem_region is now tested and ret is set to -EBUSY if the the call has failed. This call was associated with the initialization of ipw->attr_memory. But the error handling code was testing ipw->common_memory. The definition of release_ipwireless also suggests that this call should be associated with ipw->common_memory, not ipw->attr_memory. 3. The second call to request_mem_region is now tested and ret is set to -EBUSY if the the call has failed. 4. The various gotos to the error handling code is adjusted so that there is no need for ifs. 5. Return the value stored in the ret variable rather than -1. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ ( *x = request_region(...) | *x = request_mem_region(...) ) ... when != release_region(x) when != x = E * release_resource(x); // </smpl> Signed-off-by: Julia Lawall <[email protected]> Signed-off-by: Jiri Kosina <[email protected]> Signed-off-by: Dominik Brodowski <[email protected]>
2011-02-19genirq: Disable the SHIRQ_DEBUG call in request_threaded_irq for nowThomas Gleixner1-1/+1
With CONFIG_SHIRQ_DEBUG=y we call a newly installed interrupt handler in request_threaded_irq(). The original implementation (commit a304e1b8) called the handler _BEFORE_ it was installed, but that caused problems with handlers calling disable_irq_nosync(). See commit 377bf1e4. It's braindead in the first place to call disable_irq_nosync in shared handlers, but .... Moving this call after we installed the handler looks innocent, but it is very subtle broken on SMP. Interrupt handlers rely on the fact, that the irq core prevents reentrancy. Now this debug call violates that promise because we run the handler w/o the IRQ_INPROGRESS protection - which we cannot apply here because that would result in a possibly forever masked interrupt line. A concurrent real hardware interrupt on a different CPU results in handler reentrancy and can lead to complete wreckage, which was unfortunately observed in reality and took a fricking long time to debug. Leave the code here for now. We want this debug feature, but that's not easy to fix. We really should get rid of those disable_irq_nosync() abusers and remove that function completely.

2011-02-19genirq: Prevent access beyond allocated_irqs bitmapThomas Gleixner3-2/+17
Lars-Peter Clausen pointed out: I stumbled upon this while looking through the existing archs using SPARSE_IRQ. Even with SPARSE_IRQ the NR_IRQS is still the upper limit for the number of IRQs. Both PXA and MMP set NR_IRQS to IRQ_BOARD_START, with IRQ_BOARD_START being the number of IRQs used by the core. In various machine files the nr_irqs field of the ARM machine defintion struct is then set to "IRQ_BOARD_START + NR_BOARD_IRQS". As a result "nr_irqs" will greater then NR_IRQS which then again causes the "allocated_irqs" bitmap in the core irq code to be accessed beyond its size overwriting unrelated data. The core code really misses a sanity check there. This went unnoticed so far as by chance the compiler/linker places data behind that bitmap which gets initialized later on those affected platforms. So the obvious fix would be to add a sanity check in early_irq_init() and break all affected platforms. Though that check wants to be backported to stable as well, which will require to fix all known problematic platforms and probably some more yet not known ones as well. Lots of churn. A way simpler solution is to allocate a slightly larger bitmap and avoid the whole churn w/o breaking anything. Add a few warnings when an arch returns utter crap.

Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function.

2011-02-18Expand CONFIG_DEBUG_LIST to several other list operationsLinus Torvalds2-16/+35
When list debugging is enabled, we aim to readably show list corruption errors, and the basic list_add/list_del operations end up having extra debugging code in them to do some basic validation of the list entries. However, "list_del_init()" and "list_move[_tail]()" ended up avoiding the debug code due to how they were written. This fixes that. So the _next_ time we have list_move() problems with stale list entries, we'll hopefully have an easier time finding them.. Signed-off-by: Linus Torvalds <[email protected]>

2011-02-17RTC: Revert UIE emulation removalJohn Stultz3-0/+130
Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a018afcfba1d678062b62e46 - Remove UIE emulation 1daeddd5962acad1bea55e524fc0fa - Cleanup removed UIE emulation declaration b5cc8ca1c9c3a37eaddf709b2fd3e1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

2011-02-17RTC: Release mutex in error path of rtc_alarm_irq_enableUwe Kleine-König1-3/+2
On hardware that doesn't support alarm interrupts, rtc_alarm_irq_enable could return without releasing the ops_lock mutex. This was introduced in aa0be0f (RTC: Propagate error handling via rtc_timer_enqueue properly) This patch corrects the issue by only returning once the mutex is released.

2011-02-17tg3: Restrict phy ioctl accessMatt Carlson1-2/+6
If management firmware is present and the device is down, the firmware will assume control of the phy. If a phy access were allowed from the host, it will collide with firmware phy accesses, resulting in unpredictable behavior. This patch fixes the problem by disallowing phy accesses during the problematic condition.

2011-02-17drivers/net: Call netif_carrier_off at the end of the probeIvan Vecera2-0/+4
Without calling of netif_carrier_off at the end of the probe the operstate is unknown when the device is initially opened. By default the carrier is on so when the device is opened and netif_carrier_on is called the link watch event is not fired and operstate remains zero (unknown). This patch fixes this behavior in forcedeth and r8169. Signed-off-by: Ivan Vecera <[email protected]> Acked-by: Francois Romieu <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2011-02-17IB/qib: Prevent double completions after a timeout or RNR errorMike Marciniszyn1-1/+2
There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.

2011-02-17USB: musb: omap2430: fix kernel panic on rebootJohan Hovold1-0/+1
Cancel idle timer in musb_platform_exit. The idle timer could trigger after clock had been disabled leading to kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37. The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled later, and only if compiled as a module, and the offending memory access has moved) but the timer should be cancelled nonetheless.
