BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit db8466c5 ] When the separate IRQ stack was introduced, stack unwinding only proceeded as far as the top of the IRQ stack, leading to kernel backtraces being less useful, lacking the trace of what was interrupted. Fix this by providing a means for the kernel to unwind the IRQ stack onto the interrupted task stack. The processor state is saved to the kernel task stack on interrupt. The IRQ_STACK_START macro reserves an unsigned long at the top of the IRQ stack where the interrupted task stack pointer can be saved. After the active stack is switched to the IRQ stack, save the interrupted tasks stack pointer to the reserved location. Fix the stack unwinding code to look for the frame being the top of the IRQ stack and if so get the next frame from the saved location. The existing test does not work with the separate stack since the ra is no longer pointed at ret_from_{irq,exception}. The test to stop unwinding the stack 32 bytes from the top of a stack must be modified to allow unwinding to continue up to the location of the saved task stack pointer when on the IRQ stack. The low / high marks of the stack are set depending on whether the sp is on an irq stack or not. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit 3b7dabf0 ] Otherwise, another CPU may access the invalid pointer. For example: CPU0 CPU1 - rcu_read_lock(); - pfunc = _hook_; _hook_ = NULL; - mod unload - - pfunc(); // invalid, panic - rcu_read_unlock(); So we must call synchronize_rcu() to wait the rcu reader to finish. Also note, in nf_nat_snmp_basic_fini, synchronize_rcu() will be invoked by later nf_conntrack_helper_unregister, but I'm inclined to add a explicit synchronize_rcu after set the nf_nat_snmp_hook to NULL. Depend on such obscure assumptions is not a good idea. Last, in nfnetlink_cttimeout, we use kfree_rcu to free the time object, so in cttimeout_exit, invoking rcu_barrier() is not necessary at all, remove it too. Signed-off-by:

When testing switching to descriptor chain mode in meson-gx driver SDIO is broken therefore. Fix this by allocating the small DMA buffer separately as kmalloc ensures that the returned memory area is properly aligned for every basic data type. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit 37e1df8c ] This starts to handle probe deferrals on regulators and clocks on the ASoC DAPM. I came to this patch after audio stopped working on Ux500 ages ago and I finally looked into it to see what is wrong. I had messages like this in the console since a while back: ab8500-codec.0: ASoC: Failed to request audioclk: -517 ab8500-codec.0: ASoC: Failed to create DAPM control audioclk ab8500-codec.0: Failed to create new controls -12 snd-soc-mop500.0: ASoC: failed to instantiate card -12 snd-soc-mop500.0: Error: snd_soc_register_card failed (-12)! snd-soc-mop500: probe of snd-soc-mop500.0 failed with error -12 Apparently because the widget table for the codec looks like this (sound/soc/codecs/ab8500-codec.c): static const struct snd_soc_dapm_widget ab8500_dapm_widgets[] = { /* Clocks */ SND_SOC_DAPM_CLOCK_SUPPLY("audioclk"), /* Regulators */ SND_SOC_DAPM_REGULATOR_SUPPLY("V-AUD", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC1", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC2", 0, 0), SND_SOC_DAPM_REGULATOR_SUPPLY("V-DMIC", 0, 0), So when we call snd_soc_register_codec() and any of these widgets get a deferred probe we do not get an -EPROBE_DEFER (-517) back as we should and instead we just fail. Apparently the code assumes that clocks and regulators must be available at this point and not defer. After this patch it rather looks like this: ab8500-codec.0: Failed to create new controls -517 snd-soc-mop500.0: ASoC: failed to instantiate card -517 snd-soc-mop500.0: Error: snd_soc_register_card failed (-517)!

I want an indication from the maintainers whether I should just go in and augment all these call sites, or if deferred probe is frowned upon when it leads to this much overhead. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit fa2849e9 ] For some reason the axp288_adc driver was modifying the AXP288_ADC_TS_PIN_CTRL register, changing bits 0-1 depending on whether the GP_ADC channel or another channel was written. These bits control when a bias current is send to the TS_PIN, the GP_ADC has its own pin and a separate bit in another register to control the bias current. Not only does changing when to enable the TS_PIN bias current (always or only when sampling) when reading the GP_ADC make no sense at all, the code is modifying these bits is writing the entire register, assuming that all the other bits have their default value. So if the firmware has configured a different bias-current for either pin, then that change gets clobbered by the write, likewise if the firmware has set bit 2 to indicate that the battery has no thermal sensor, this will get clobbered by the write. This commit fixes all this, by simply removing all writes to the AXP288_ADC_TS_PIN_CTRL register, they are not needed to read the GP_ADC pin, and can actually be harmful. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit 69b97cf6 ] Whenever the igb driver detects the result of a read operation returns a value composed only by F's (like 0xFFFFFFFF), it will detach the net_device, clear the hw_addr pointer and warn to the user that adapter's link is lost - those steps happen on igb_rd32(). In case a PCI error happens on Power architecture, there's a recovery mechanism called EEH, that will reset the PCI slot and call driver's handlers to reset the adapter and network functionality as well. We observed that once hw_addr is NULL after the error is detected on igb_rd32(), it's never assigned back, so in the process of resetting the network functionality we got a NULL pointer dereference in both igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid such bug, this patch re-assigns the hw_addr value in the slot_reset handler. Reported-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit 3f00f4d8 ] When clearing the .bss section in kernel_entry we do so using LONG_S instructions, and branch whilst the current write address doesn't equal the end of the .bss section minus the size of a long integer. The .bss section always begins at a long-aligned address and we always increment the write pointer by the size of a long integer - we therefore rely upon the .bss section ending at a long-aligned address. If this is not the case then the long-aligned write address can never be equal to the non-long-aligned end address & we will continue to increment past the end of the .bss section, attempting to zero the rest of memory. Despite this requirement that .bss end at a long-aligned address we pass 0 as the end alignment requirement to the BSS_SECTION macro and thus don't guarantee any particular alignment, allowing us to hit the error condition described above. Fix this by instead passing 8 bytes as the end alignment argument to the BSS_SECTION macro, ensuring that the end of the .bss section is always at least long-aligned. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1724772 [ Upstream commit 941f8d55 ] When application sends an RDS RDMA composite message consist of RDMA transfer to be followed up by non RDMA payload, it expect to be notified *only* when the full message gets delivered. RDS RDMA notification doesn't behave this way though. Thanks to Venkat for debug and root casuing the issue where only first part of the message(RDMA) was successfully delivered but remainder payload delivery failed. In that case, application should not be notified with a false positive of message delivery success. Fix this case by making sure the user gets notified only after the full message delivery.

Ignore: yes Make insert-ubuntu-changes to consider full version numbers when looping through debian.master/changelog entries and comparing the version number of each entry with the arguments passed to the script to decide which entries should be included in the output changelog file. Previously, only the last number in the version was used in this comparison. For example, when comparing 4.4.0-50.51 and 4.4.0-83.84 only the numbers 51 and 84 were actually used in the comparison. That however might not work properly when the major version is bumped. For instance, using "end" as 4.4.0-50.51 and "start" as 4.4.0-83.84 used to work fine because 84 is greater than 51. However when using "end" as 4.11.0-10.11 and "start" as 4.13.0-2.3, no entry was being selected since 3 is not greater than 11. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1720359 The hpsa firmware will bypass the cache for any request larger than 1MB, so we should cap the request size to avoid any performance degradation in kernels later than v4.3 This degradation is caused from d2be537c, which changed max_sectors_kb to 1280k, but the hardware is able to work fine with it, so the true fix should be from hpsa driver.
