2016-01-27Input: serio - drop warnings in case of EPROBE_DEFER from serio_find_driver()Grygorii Strashko
Now serio_find_driver() will print warnings in case device_attach() returns -EPROBE_DEFER. Those warnings are obsolete, in genral, because: - DD core can report the same if required - since commit 013c074f8642 ("PM / sleep: prohibit devices probing during suspend/hibernation") the devices probing is prohibited during System suspend and deferred device will be carefully reprobed once Resume is finished. Hence, drop warnings in case of EPROBE_DEFER from serio_find_driver(). Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Rafael J.

2016-01-27Input: sirfsoc-onkey - allow modular buildArnd Bergmann
CONFIG_INPUT may itself be a loadable module, but the sirf power key driver is listed as 'bool', which makes it possible to select a broken configuration with the driver built-in but the subsystem not loaded. In this configuration, we get a link error: drivers/input/built-in.o: In function `sirfsoc_pwrc_isr': drivers/input/misc/sirfsoc-onkey.c:63: undefined reference to `input_event' drivers/input/built-in.o: In function `sirfsoc_pwrc_isr': include/linux/input.h:414: undefined reference to `input_event' drivers/input/built-in.o: In function `sirfsoc_pwrc_probe': drivers/input/misc/sirfsoc-onkey.c:132: undefined reference to `devm_input_allocate_device' drivers/input/misc/sirfsoc-onkey.c:139: undefined reference to `input_set_capability' drivers/input/misc/sirfsoc-onkey.c:161: undefined reference to `input_register_device' drivers/input/built-in.o: In function `sirfsoc_pwrc_report_event': drivers/input/misc/sirfsoc-onkey.c:48: undefined reference to `input_event' drivers/input/built-in.o: In function `sirfsoc_pwrc_report_event': include/linux/input.h:414: undefined reference to `input_event' drivers/input/built-in.o:(.debug_addr+0x24): undefined reference to `input_event' drivers/input/built-in.o:(.debug_addr+0xbc): undefined reference to `devm_input_allocate_device' drivers/input/built-in.o:(.debug_addr+0x104): undefined reference to `input_set_capability' drivers/input/built-in.o:(.debug_addr+0x128): undefined reference to `input_register_device' This marks the driver as 'tristate' so it becomes possible to have it in a loadable module, mainly to help with randconfig builds. We also have to add a missing semicolon here, which ended up not being needed in built-in mode because the following MODULE_DEVICE_TABLE is an empty macro followed by another semicolon then.

2016-01-28KEYS: Only apply KEY_FLAG_KEEP to a key if a parent keyring has it setDavid Howells
KEY_FLAG_KEEP should only be applied to a key if the keyring it is being linked into has KEY_FLAG_KEEP set. To this end, partially revert the following patch: commit 1d6d167c2efcfe9539d9cffb1a1be9c92e39c2c0 Author: Mimi Zohar <zohar@linux.vnet.ibm.com> Date: Thu Jan 7 07:46:36 2016 -0500 KEYS: refcount bug fix to undo the change that made it unconditional (Mimi got it right the first time). Without undoing this change, it becomes impossible to delete, revoke or invalidate keys added to keyrings through __key_instantiate_and_link() where the keyring has itself been linked to. To test this, run the following command sequence: keyctl newring foo @s keyctl add user a a %:foo keyctl unlink %user:a %:foo keyctl clear %:foo With the commit mentioned above the third and fourth commands fail with EPERM when they should succeed.

There are two definitions of pxa_cpufreq_change_voltage, with slightly different prototypes after one of them had its argument marked 'const'. Now the other one (for !CONFIG_REGULATOR) produces a harmless warning: drivers/cpufreq/pxa2xx-cpufreq.c: In function 'pxa_set_target': drivers/cpufreq/pxa2xx-cpufreq.c:291:36: warning: passing argument 1 of 'pxa_cpufreq_change_voltage' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] ret = pxa_cpufreq_change_voltage(&pxa_freq_settings[idx]); ^ drivers/cpufreq/pxa2xx-cpufreq.c:205:12: note: expected 'struct pxa_freqs *' but argument is of type 'const struct pxa_freqs *' static int pxa_cpufreq_change_voltage(struct pxa_freqs *pxa_freq) ^ This changes the prototype in the same way as the other, which avoids the warning.

2016-01-27PM: APM_EMULATION does not depend on PMArnd Bergmann
The APM emulation code does multiple things, and some of them depend on PM_SLEEP, while the battery management does not. However, selecting the symbol like SHARPSL_PM does causes a Kconfig warning: warning: (SHARPSL_PM && PMAC_APM_EMU) selects APM_EMULATION which has unmet direct dependencies (PM && SYS_SUPPORTS_APM_EMULATION) From all I can tell, this is completely harmless, and we can simply allow APM_EMULATION to be enabled here, even if PM is not.

2016-01-27PM / Domains: Fix potential deadlock while adding/removing subdomainsUlf Hansson
We must preserve the same order of how we acquire and release the lock for genpd, as otherwise we may encounter deadlocks. The power on phase of a genpd starts by acquiring its lock. Then it walks the hierarchy of its parent domains to be able to power on these first, as per design of genpd. From a locking perspective this means the locks of the parents becomes acquired after the lock of the subdomain. Let's fix pm_genpd_add|remove_subdomain() to maintain the same order of acquiring/releasing the genpd lock as being applied in the power on/off sequence.

2016-01-27vfio/noiommu: Don't use iommu_present() to track fake groupsAlex Williamson
Using iommu_present() to determine whether an IOMMU group is real or fake has some problems. First, apparently Power systems don't register an IOMMU on the device bus, so the groups and containers get marked as noiommu and then won't bind to their actual IOMMU driver. Second, I expect we'll run into the same issue as we try to support vGPUs through vfio, since they're likely to emulate this behavior of creating an IOMMU group on a virtual device and then providing a vfio IOMMU backend tailored to the sort of isolation they provide, which won't necessarily be fully compatible with the IOMMU API. The solution here is to use the existing iommudata interface to IOMMU groups, which allows us to easily identify the fake groups we've created for noiommu purposes. The iommudata we set is purely arbitrary since we're only comparing the address, so we use the address of the noiommu switch itself.

2016-01-27ARM: dts: am437x: pixcir_tangoc: use correct flags for irq typesGrygorii Strashko
Now IRQs for Pixcir Tangoc touchscreen are defined using IRQ_TYPE_NONE in am437x-gp-evm.dts and am43x-epos-evm.dts wich do not correspond HW. Hence, update am437x-gp-evm.dts and am43x-epos-evm.dts files and use correct flag IRQ_TYPE_EDGE_FALLING for irq types. While here, remove duplicated irq declaration for pixcir_ts@5c node in am437x-gp-evm.dts. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2016-01-27ARM: dts: am4372: fix irq type for arm twd and global timerGrygorii Strashko
As per ARM documentation PPI(0) ID27 - global timer interrupt is rising-edge sensitive. PPI(2) ID29 - twd interrupt is rising-edge sensitive. and the same is proved by GIC distributor register value GIC_DIST_CONFIG(0xC04) = 0x7DC00000. Hence, set IRQ triggering type to IRQ_TYPE_EDGE_RISING for ARM TWD and Global timers. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2016-01-27debugobjects: Allow bigger number of early boot objectsChristian Borntraeger
On my bigger s390 systems I always get "Out of memory. ODEBUG disabled". Since the number of objects is needed at compile time, we can not change the size dynamically before the caches etc are available. Doubling the size seems to do the trick. Since it is init data it will be freed anyway, this should be ok.

2016-01-27irqchip/atmel-aic: Fix wrong bit operation for IRQ priorityMilo Kim
Atmel AIC has common structure for SMR (Source Mode Register). bit[6:5] Interrupt source type bit[2:0] Priority level Other bits are unused. To update new priority value, bit[2:0] should be cleared first and then new priority level can be written. However, aic_common_set_priority() helper clears source type bits instead of priority bits.

commit 0ff53d096422 sets the next tick interrupt to the last jiffies update, i.e. in the past, because the forward operation is invoked before the set operation. There is no resulting damage (yet), but we get an extra pointless tick interrupt. Revert the order so we get the next tick interrupt in the future.

After 57a38effa598 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091) the macb0 interface has difficulties to come back from power saving mode if address not explicitly set up. As the micrel phy on the board is actually configured to show up at address 1 we use this explicitly. Adding the phy node and its real address fixes the issue. The phy IRQ and associated pinmux node is also added.
