2012-08-16IB/mlx4: Check iboe netdev pointer before dereferencing itKleber Sacilotto de Souza
Unlike other parts of the mlx4_ib code, the function build_mlx_header() doesn't check if the iboe netdev of the given port is valid before dereferencing it, which can cause a crash if the ethernet interface has already been taken down. Fix this by checking for a valid netdev pointer before using it to get the port MAC address.

2012-08-16md: Don't truncate size at 4TB for RAID0 and LinearNeilBrown
commit 27a7b260f71439c40546b43588448faac01adb93 md: Fix handling for devices from 2TB to 4TB in 0.90 metadata. changed 0.90 metadata handling to truncated size to 4TB as that is all that 0.90 can record. However for RAID0 and Linear, 0.90 doesn't need to record the size, so this truncation is not needed and causes working arrays to become too small. So avoid the truncation for RAID0 and Linear This bug was introduced in 3.1 and is suitable for any stable kernels from then onwards. As the offending commit was tagged for 'stable', any stable kernel that it was applied to should also get this patch. That includes at least 2.6.32, 2.6.33 and 3.0.

2012-08-16ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture streamTakashi Iwai
A PCM capture stream on usb-audio causes a scheduling-while-atomic BUG, as reported in the bugzilla entry below. It's because snd_usb_endpoint_start() is called at first at trigger START for a capture stream, and this function contains the left-over EP deactivation codes. The problem doesn't happen for a playback stream because the function is called at PCM prepare time, which can sleep. This patch fixes the BUG by moving the EP deactivation code into the PCM prepare callback.

2012-08-15mlx4_core: Fix integer overflow issues around MTT tableYishai Hadas
Fix some issues around int variables used in data structures related to memory registration. Handle int overflow in mlx4_init_icm_table by using a u64 intermediate variable and changing struct mlx4_icm_table num_obj field to be u32. Change some more fields/variables to use u32 instead of int to prevent a case where the variable becomes negative when bit 31 is set. Also subtract log_mtts_per_seg from the exponent when computing num_mtt, since its added later on in that very same code area. This and the previous commit fixes some issues which actually prevent commit db5a7a65c058 ("mlx4_core: Scale size of MTT table with system RAM") from working. Now, when the number of MTTs is scaled with the size of the RAM we can map up to 8TB.

2012-08-15mlx4_core: Allow large mlx4_buddy bitmapsYishai Hadas
mlx4_buddy_init uses kmalloc() to allocate bitmaps, which fails when the required size is beyond the max supported value (or when memory is too fragmented to handle a huge allocation). Extend this to use use vmalloc() if kmalloc() fails, and take that into account when freeing the bitmaps as well. This fixes a driver load failure when log num mtt is 26 or higher, and is a step in the direction of allowing to register huge amounts of memory on large memory systems.

Commit dbf0e4c (PCI: EHCI: fix crash during suspend on ASUS computers) added a workaround for an ASUS suspend issue related to USB EHCI and a bug in a number of ASUS BIOSes that attempt to shut down the EHCI controller during system suspend if its PCI command register doesn't contain 0 at that time. It turns out that the same workaround is necessary in the analogous hibernation code path, so add it.

If a PCI device is put into D3_cold by acpi_bus_set_power(), the message printed by acpi_pci_set_power_state() says that its power state has been changed to D4, which doesn't make sense. In turn, if the device is put into D3_hot, the message simply says "D3" without specifying the variant of the D3 state.

2012-08-15audit: fix refcounting in audit-treeMiklos Szeredi
Refcounting of fsnotify_mark in audit tree is broken. E.g: refcount create_chunk alloc_chunk 1 fsnotify_add_mark 2 untag_chunk fsnotify_get_mark 3 fsnotify_destroy_mark audit_tree_freeing_mark 2 fsnotify_put_mark 1 fsnotify_put_mark 0 via destroy_list fsnotify_mark_destroy -1 This was reported by various people as triggering Oops when stopping auditd. We could just remove the put_mark from audit_tree_freeing_mark() but that would break freeing via inode destruction. So this patch simply omits a put_mark after calling destroy_mark or adds a get_mark before. The additional get_mark is necessary where there's no other put_mark after fsnotify_destroy_mark() since it assumes that the caller is holding a reference (or the inode is keeping the mark pinned, not the case here AFAICS).

2012-08-14x86, apic: fix broken legacy interrupts in the logical apic modeSuresh Siddha
Recent commit 332afa656e76458ee9cf0f0d123016a0658539e4 cleaned up a workaround that updates irq_cfg domain for legacy irq's that are handled by the IO-APIC. This was assuming that the recent changes in assign_irq_vector() were sufficient to remove the workaround. But this broke couple of AMD platforms. One of them seems to be sending interrupts to the offline cpu's, resulting in spurious "No irq handler for vector xx (irq -1)" messages when those cpu's come online. And the other platform seems to always send the interrupt to the last logical CPU (cpu-7). Recent changes had an unintended side effect of using only logical cpu-0 in the IO-APIC RTE (during boot for the legacy interrupts) and this broke the legacy interrupts not getting routed to the cpu-7 on the AMD platform, resulting in a boot hang. For now, reintroduce the removed workaround, (essentially not allowing the vector to change for legacy irq's when io-apic starts to handle the irq. Which also addressed the uninteded sife effect of just specifying cpu-0 in the IO-APIC RTE for those irq's during boot).

2012-08-14drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter
eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

2012-08-14GPIO: gpio-pxa: fix building without CONFIG_OFArnd Bergmann
Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

This fix is a backport from the reworked nouveau driver. It masks off the engines we're not expecting to use before attempting a channel kickoff. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-08-14drm/nouveau: disable copy engine on NVAFHenrik Rydberg
The copy engine exhibits random memory corruption in at least one case, the GeForce 320M (nv50, 0xaf) in the MacBookAir3,1. This patch omits creating the engine for the specific chipset, falling back to M2MF, which kills the symptoms.

At least partially fixes DP output detection on W530. Not sure if more issues remain, or if my adaptor is just behaving weirdly (it does that sometimes). In any case, this patch is necessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
