2019-09-11regulator: da9211: fix obtaining "enable" GPIODmitry Torokhov
This fixes 11da04af0d3b, as devm_gpiod_get_from_of_node() does not do translation "con-id" -> "con-id-gpios" that our bindings expects, and therefore it was wrong to change connection ID to be simply "enable" when moving to using devm_gpiod_get_from_of_node().

2019-09-11gpio: aspeed: Add in ast2600 details to Aspeed driverRashmica Gupta
The ast2600 is a new generation of SoC from ASPEED. Similarly to the ast2400 and ast2500, it has a GPIO controller for it's 3.3V GPIO pins. Additionally, it has a GPIO controller for 1.8V GPIO pins. As the register names for both controllers are the same and the 36 1.8V GPIOs and the first 36 of the 3.3V GPIOs are all bidirectional, we can use the same configuration struct and use the ngpio property to differentiate between the two sets of GPIOs.

2019-09-11gpiolib: acpi: Add gpiolib_acpi_run_edge_events_on_boot option and blacklistHans de Goede
Another day; another DSDT bug we need to workaround... Since commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge events at least once on boot") we call _AEI edge handlers at boot. In some rare cases this causes problems. One example of this is the Minix Neo Z83-4 mini PC, this device has a clear DSDT bug where it has some copy and pasted code for dealing with Micro USB-B connector host/device role switching, while the mini PC does not even have a micro-USB connector. This code, which should not be there, messes with the DDC data pin from the HDMI connector (switching it to GPIO mode) breaking HDMI support. To avoid problems like this, this commit adds a new gpiolib_acpi.run_edge_events_on_boot kernel commandline option, which allows disabling the running of _AEI edge event handlers at boot. The default value is -1/auto which uses a DMI based blacklist, the initial version of this blacklist contains the Neo Z83-4 fixing the HDMI breakage.

2019-09-11gpio: Initialize the irqchip valid_mask with a callbackLinus Walleij
After changing the valid_mask for the struct gpio_chip to detect the need and presence of a valid mask with the presence of a .init_valid_mask() callback to fill it in, we augment the gpio_irq_chip to use the same logic. Switch all driver using the gpio_irq_chio valid_mask over to this new method. This makes sure the valid_mask for the gpio_irq_chip gets filled in when we add the gpio_chip, which makes it a little easier to switch over drivers using the old way of setting up gpio_irq_chip over to the new method of passing the gpio_irq_chip along with the gpio_chip.

2019-09-10waitid: Add support for waiting for the current process groupEric W. Biederman
It was recently discovered that the linux version of waitid is not a superset of the other wait functions because it does not include support for waiting for the current process group. This has two downsides: 1. An extra system call is needed to get the current process group. 2. After the current process group is received and before it is passed to waitid a signal could arrive causing the current process group to change. Inherent race-conditions as these make it impossible for userspace to emulate this functionaly and thus violate async-signal safety requirements for waitpid. Arguments can be made for using a different choice of idtype and id for this case but the BSDs already use this P_PGID and 0 to indicate waiting for the current process's process group. So be nice to user space programmers and don't introduce an unnecessary incompatibility. Some people have noted that the posix description is that waitpid will wait for the current process group, and that in the presence of pthreads that process group can change. To get clarity on this issue I looked at XNU, FreeBSD, and Luminos. All of those flavors of unix waited for the current process group at the time of call and as written could not adapt to the process group changing after the call. At one point Linux did adapt to the current process group changing but that stopped in 161550d74c07 ("pid: sys_wait... fixes"). It has been over 11 years since Linux has that behavior, no programs that fail with the change in behavior have been reported, and I could not find any other unix that does this. So I think it is safe to clarify the definition of current process group, to current process group at the time of the wait function. Signed-off-by: "Eric W.

2019-09-10posix-cpu-timers: Fix permission check regressionThomas Gleixner
The recent consolidation of the three permission checks introduced a subtle regression. For timer_create() with a process wide timer it returns the current task if the lookup through the PID which is encoded into the clockid results in returning current. That's broken because it does not validate whether the current task is the group leader. That was caused by the two different variants of permission checks: - posix_cpu_timer_get() allowed access to the process wide clock when the looked up task is current. That's not an issue because the process wide clock is in the shared sighand. - posix_cpu_timer_create() made sure that the looked up task is the group leader. Restore the previous state. Note, that these permission checks are more than questionable, but that's subject to follow up changes.

We should only try to execute fallback quirks handling when previous call returned -ENOENT, and not when we did not get -EPROBE_DEFER. The other errors should be treated as hard errors: we did find the GPIO description, but for some reason we failed to handle it properly. The fallbacks should only be executed when previous handlers returned -ENOENT, which means the mapping/description was not found. Also let's remove the explicit deferral handling when iterating through GPIO suffixes: it is not needed anymore as we will not be calling fallbacks for anything but -ENOENT.

2019-09-10spi: bcm2835: Work around DONE bit erratumLukas Wunner
Commit 3bd7f6589f67 ("spi: bcm2835: Overcome sglist entry length limitation") amended the BCM2835 SPI driver with support for DMA transfers whose buffers are not aligned to 4 bytes and require more than one sglist entry. When testing this feature with upcoming commits to speed up TX-only and RX-only transfers, I noticed that SPI transmission sometimes breaks. A function introduced by the commit, bcm2835_spi_transfer_prologue(), performs one or two PIO transmissions as a prologue to the actual DMA transmission. It turns out that the breakage goes away if the DONE bit in the CS register is set when ending such a PIO transmission. The DONE bit signifies emptiness of the TX FIFO. According to the spec, the bit is of type RO, so writing it should never have any effect. Perhaps the spec is wrong and the bit is actually of type RW1C. E.g. the I2C controller on the BCM2835 does have an RW1C DONE bit which needs to be cleared by the driver. Another, possibly more likely explanation is that it's a hardware erratum since the issue does not occur consistently. Either way, amend bcm2835_spi_transfer_prologue() to always write the DONE bit. Usually a transmission is ended by bcm2835_spi_reset_hw(). If the transmission was successful, the TX FIFO is empty and thus the DONE bit is set when bcm2835_spi_reset_hw() reads the CS register. The bit is then written back to the register, so we happen to do the right thing. However if DONE is not set, e.g. because transmission is aborted with a non-empty TX FIFO, the bit won't be written by bcm2835_spi_reset_hw() and it seems possible that transmission might subsequently break. To be on the safe side, likewise amend bcm2835_spi_reset_hw() to always write the bit.

2019-09-09virtio_ring: fix unmap of indirect descriptorsMatthias Lange
The function virtqueue_add_split() DMA-maps the scatterlist buffers. In case a mapping error occurs the already mapped buffers must be unmapped. This happens by jumping to the 'unmap_release' label. In case of indirect descriptors the release is wrong and may leak kernel memory. Because the implementation assumes that the head descriptor is already mapped it starts iterating over the descriptor list starting from the head descriptor. However for indirect descriptors the head descriptor is never mapped in case of an error. The fix is to initialize the start index with zero in case of indirect descriptors and use the 'desc' pointer directly for iterating over the descriptor chain.

2019-09-09drm/i915: Restore relaxed padding (OCL_OOB_SUPPRES_ENABLE) for skl+Chris Wilson
This bit was fliped on for "syncing dependencies between camera and graphics". BSpec has no recollection why, and it is causing unrecoverable GPU hangs with Vulkan compute workloads. From BSpec, setting bit5 to 0 enables relaxed padding requirements for buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces; and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is suppressed.

2019-09-09drm/i915: Limit MST to <= 8bpc once againVille Syrjälä
My attempt at allowing MST to use the higher color depths has regressed some configurations. Apparently people have setups where all MST streams will fit into the DP link with 8bpc but won't fit with higher color depths. What we really should be doing is reducing the bpc for all the streams on the same link until they start to fit. But that requires a bit more work, so in the meantime let's revert back closer to the old behavior and limit MST to at most 8bpc.

2019-09-09regulator: slg51000: use devm_gpiod_get_optional() in probeDmitry Torokhov
The CS GPIO line is clearly optional GPIO (and marked as such in the binding document) and we should handle it accordingly. The current code treats all errors as meaning that there is no GPIO defined, which is wrong, as it does not handle deferrals raised by the underlying code properly, nor does it recognize non-existing GPIO from any other initialization error. As far as I can see the only reason the driver, unlike all others, is using OF-specific devm_gpiod_get_from_of_node() so that it can assign a custom label to the selected GPIO line. Given that noone else needs that, it should not be doing that either. Let's switch to using more appropriate devm_gpiod_get_optional().
