commit d5359226 upstream. There is a bug in mvebu_gpio_probe() where we do: mvchip->irqbase = irq_alloc_descs(-1, 0, ngpios, -1); if (mvchip->irqbase < 0) { The problem is that mvchip->irqbase is unsigned so the error handling doesn't work. I have changed it to be a regular int. Signed-off-by:

commit 0b2aa8be upstream. Commit c111feab (gpio: twl4030: Cache the direction and output states in private data) improved things in general, but caused a regression for setting the GPIO output direction. The change reorganized twl_direction_out() and twl_set() and swapped the function names around in the process. While doing that, a bug got introduced that's not obvious while reading the patch as it appears as no change to the code. The bug is we now call function twl4030_set_gpio_dataout() twice in both twl_direction_out() and twl_set(). Instead, we should first call twl_direction_out() in twl_direction_out() followed by twl4030_set_gpio_dataout() in twl_set(). This regression probably has gone unnoticed for a long time as the bootloader may have set the GPIO direction properly in many cases. This fixes at least the LCD panel not turning on omap3 LDP for example. Cc: linux-gpio@vger.kernel.org Reviewed-by:

commit 8c0ec250 upstream. The i2c-mux driver requires that the chan_id parameter passed to the i2c_add_mux_adapter() function is equal to the reg value for that adapter: for_each_child_of_node(mux_dev->of_node, child) { ret = of_property_read_u32(child, "reg", ®); if (ret) continue; if (chan_id == reg) { priv->adap.dev.of_node = child; break; } } The i2c-mux-gpio driver uses an internal logical index for chan_id when calling i2c_add_mux_adapter() instead of using the reg value. Because of this, there will problems in selecting the right adapter when the i2c-mux-gpio's index into mux->data.values doesn't match the reg value. An example of such a case: mux->data.values = { 1, 0 } For chan_id = 0, i2c-mux will bind the adapter to the of_node with reg = <0>, but when it will call the select() callback with chan_id set to 0, the i2c-mux-gpio will use it as an index into mux->data.values and it will actually select the bus with reg = <1>.

commit 0d1862ea upstream. In the flexcan_chip_start() function first the flexcan core is going through the soft reset sequence, then the RX FIFO is enabled. With the hardware is put into FIFO mode, message buffers 1...7 are reserved by the FIFO engine. The remaining message buffers are in reset default values. This patch removes the bogus initialization of the message buffers, as it causes an imprecise external abort on imx6. Reported-by:

commit 66da0e1f upstream. When devpts is unmounted, there may be a no-longer-used IDR tree hanging off the superblock we are about to kill. This needs to be cleaned up before destroying the SB. The leak is usually not a big deal because unmounting devpts is typically done when shutting down the whole machine. However, shutting down an LXC container instead of a physical machine exposes the problem (the garbage is detectable with kmemleak). Signed-off-by:

commit 98d6f4dd upstream. Fedora Ruby maintainer reported latest Ruby doesn't work on Fedora Rawhide on ARM. (http://bugs.ruby-lang.org/issues/9008) Because of, commit 1c6b39ad (alarmtimers: Return -ENOTSUPP if no RTC device is present) intruduced to return ENOTSUPP when clock_get{time,res} can't find a RTC device. However this is incorrect. First, ENOTSUPP isn't exported to userland (ENOTSUP or EOPNOTSUP are the closest userland equivlents). Second, Posix and Linux man pages agree that clock_gettime and clock_getres should return EINVAL if clk_id argument is invalid. While the arugment that the clockid is valid, but just not supported on this hardware could be made, this is just a technicality that doesn't help userspace applicaitons, and only complicates error handling. Thus, this patch changes the code to use EINVAL. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> Reported-by:

commit fc7dc61d upstream. Unbalanced calls to snd_imx_pcm_trigger() may result in endless FIQ activity and thus provoke eternal sound. While on the first glance, the switch statement looks pretty symmetric, the SUSPEND/RESUME pair is not: the suspend case comes along snd_pcm_suspend_all(), which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(), but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME. This way userland may provoke an unbalanced resume, which might cause the fiq_enable counter to increase and never return to zero again, so eventually imx_pcm_fiq is never disabled. Simply removing the fiq_enable will solve the problem, as long as one never goes play and capture game simultaneously, but beware trying both at once, the early TRIGGER_STOP will cut off the other activity prematurely. So now playing and capturing is scrutinized separately, instead of by counting. Signed-off-by:

commit 67296874 upstream. zsmalloc encodes a handle using the pfn and an object index. On hardware platforms with physical memory starting at 0x0 the pfn can be 0. This causes the encoded handle to be 0 and is incorrectly interpreted as an allocation failure. This issue affects all current and future SoCs with physical memory starting at 0x0. All MSM8974 SoCs which includes Google Nexus 5 devices are affected. To prevent this false error we ensure that the encoded handle will not be 0 when allocation succeeds. Signed-off-by:

commit 94c4c79f upstream. Make sure the RTT-interrupts are masked at boot by adding a new helper function to be used at SOC-init. This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC wakeup). The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or software reset. This means that their interrupts may be enabled during early boot if, for example, they where not disabled during a previous shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a user reset). Furthermore, an RTC or RTT-alarm may also be active. The RTC and RTT-interrupts use the shared system-interrupt line, which is also used by the PIT, and if an interrupt occurs before a handler (e.g. RTC-driver) has been installed this leads to the system interrupt being disabled and prevents the system from booting. Note that when boot hangs due to an early RTC or RTT-interrupt, the only way to get the system to start again is to remove the backup power (e.g. battery) or to disable the interrupt manually from the bootloader. In particular, a user reset is not sufficient. Signed-off-by:

commit 0219132f upstream. STI text console (sticon) was broken on 64bit machines with more than 4GB RAM and this lead in some cases to a kernel crash. Since sticon uses the 32bit STI API it needs to keep pointers to memory below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel stack) might be above 4GB which then may crash the kernel in the STI functions. Additionally sticon didn't selected the built-in framebuffer fonts by default. This is now fixed. On a side-note: Theoretically we could enhance the sticon driver to use the 64bit STI API. But - beside the fact that some machines don't provide a 64bit STI ROM - this would just add complexity. Signed-off-by:

commit 76ae281f upstream. A race window in configfs, it starts from one dentry is UNHASHED and end before configfs_d_iput is called. In this window, if a lookup happen, since the original dentry was UNHASHED, so a new dentry will be allocated, and then in configfs_attach_attr(), sd->s_dentry will be updated to the new dentry. Then in configfs_d_iput(), BUG_ON(sd->s_dentry != dentry) will be triggered and system panic. sys_open: sys_close: ... fput dput dentry_kill __d_drop <--- dentry unhashed here, but sd->dentry still point to this dentry. lookup_real configfs_lookup configfs_attach_attr---> update sd->s_dentry to new allocated dentry here. d_kill configfs_d_iput <--- BUG_ON(sd->s_dentry != dentry) triggered here. To fix it, change configfs_d_iput to not update sd->s_dentry if sd->s_count > 2, that means there are another dentry is using the sd beside the one that is going to be put. Use configfs_dirent_lock in configfs_attach_attr to sync with configfs_d_iput. With the following steps, you can reproduce the bug. 1. enable ocfs2, this will mount configfs at /sys/kernel/config and fill configure in it. 2. run the following script. while [ 1 ]; do cat /sys/kernel/config/cluster/$your_cluster_name/idle_timeout_ms > /dev/null; done & while [ 1 ]; do cat /sys/kernel/config/cluster/$your_cluster_name/idle_timeout_ms > /dev/null; done & Signed-off-by:
