2012-06-22net: qmi_wwan: fix Gobi device probingBjørn Mork1-43/+40
Ignoring interfaces with additional descriptors is not a reliable method for locating the correct interface on Gobi devices. There is at least one device where this method fails: https://bbs.archlinux.org/viewtopic.php?id=143506 The result is that the AT command port (interface #2) is hidden from qcserial, preventing traditional serial modem usage: [ 15.562552] qmi_wwan 4-1.6:1.0: cdc-wdm0: USB WDM device [ 15.562691] qmi_wwan 4-1.6:1.0: wwan0: register 'qmi_wwan' at usb-0000:00:1d.0-1.6, Qualcomm Gobi wwan/QMI device, 1e:df:3c:3a:4e:3b [ 15.563383] qmi_wwan: probe of 4-1.6:1.1 failed with error -22 [ 15.564189] qmi_wwan 4-1.6:1.2: cdc-wdm1: USB WDM device [ 15.564302] qmi_wwan 4-1.6:1.2: wwan1: register 'qmi_wwan' at usb-0000:00:1d.0-1.6, Qualcomm Gobi wwan/QMI device, 1e:df:3c:3a:4e:3b [ 15.564328] qmi_wwan: probe of 4-1.6:1.3 failed with error -22 [ 15.569376] qcserial 4-1.6:1.1: Qualcomm USB modem converter detected [ 15.569440] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB0 [ 15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected [ 15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1 Use static interface numbers taken from the interface map in qcserial for all Gobi devices instead: Gobi 1K USB layout: 0: serial port (doesn't respond) 1: serial port (doesn't respond) 2: AT-capable modem port 3: QMI/net Gobi 2K+ USB layout: 0: QMI/net 1: DM/DIAG (use libqcdm from ModemManager for communication) 2: AT-capable modem port 3: NMEA This should be more reliable over all, and will also prevent the noisy "probe failed" messages.

This patch fixes the problem on some HP desktop machines with eDP which give blank screens after S3 resume. It turned out that BLC_PWM_CPU_CTL must be written after BLC_PWM_CPU_CTL2.

2012-06-23drm/i915: rip out the PM_IIR WARNDaniel Vetter1-1/+0
After banging my head against this for the past few months, I still don't see how this could possible race under the premise that once an irq bit is masked in PM_IMR and reset in PM_IIR it won't show up again until we unmask it in PM_IMR. Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

As per the OMAP4 documentation, audio over HDMI must be transmitted in no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses no-idle/force-idle settings instead of smart-idle mode. This is required as the DSS interface clock is used as functional clock for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could be choppy, have bad quality or not be audible at all.

2012-06-21xfs: Fix overallocation in xfs_buf_allocate_memory()Jan Kara1-14/+2
Commit de1cbee which removed b_file_offset in favor of b_bn introduced a bug causing xfs_buf_allocate_memory() to overestimate the number of necessary pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

2012-06-21xfs: check for stale inode before acquiring iflock on pushBrian Foster1-9/+8
An inode in the AIL can be flush locked and marked stale if a cluster free transaction occurs at the right time. The inode item is then marked as flushing, which causes xfsaild to spin and leaves the filesystem stalled. This is reproduced by running xfstests 273 in a loop for an extended period of time. Check for stale inodes before the flush lock. This marks the inode as pinned, leads to a log flush and allows the filesystem to proceed.

2012-06-20mm/memblock: fix overlapping allocation when doubling reserved arrayGreg Pearson1-4/+32
__alloc_memory_core_early() asks memblock for a range of memory then try to reserve it. If the reserved region array lacks space for the new range, memblock_double_array() is called to allocate more space for the array. If memblock is used to allocate memory for the new array it can end up using a range that overlaps with the range originally allocated in __alloc_memory_core_early(), leading to possible data corruption. With this patch memblock_double_array() now calls memblock_find_in_range() with a narrowed candidate range (in cases where the reserved.regions array is being doubled) so any memory allocated will not overlap with the original range that was being reserved. The range is narrowed by passing in the starting address and size of the previously allocated range. Then the range above the ending address is searched and if a candidate is not found, the range below the starting address is searched.
