2014-07-30Documentation: bindings: document the sub-nodes AHCI bindingsAntoine Ténart
The libahci now allows to use multiple PHYs and to represent each port as a sub-node. Add these bindings to the documentation. Signed-off-by: Antoine Ténart <antoine.tenart@free-electrons.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2014-07-30ata: ahci_platform: add a generic AHCI compatibleAntoine Ténart
The ahci_platform driver is a generic driver using the libahci_platform functions. Add a generic compatible to avoid having an endless list of compatibles with no differences for the same driver. Signed-off-by: Antoine Ténart <antoine.tenart@free-electrons.com>
2014-07-30ata: libahci: allow to use multiple PHYsAntoine Ténart
The current implementation of the libahci does not allow to use multiple PHYs. This patch adds the support of multiple PHYs by the libahci while keeping the old bindings valid for device tree compatibility. This introduce a new way of defining SATA ports in the device tree, with one port per sub-node. This as the advantage of allowing a per port configuration. Because some ports may be accessible but disabled in the device tree, the port_map mask is computed automatically when using this.

2014-07-30ata: libahci_platform: move port_map parameters into the AHCI structureAntoine Ténart
This patch moves force_port_map and mask_port_map into the ahci_host_priv structure. This allows to modify them into the AHCI framework. This is needed by the new dt bindings representing ports as the port_map mask is computed automatically. Parameters modifying force_port_map, mask_port_map and flags have been removed from the ahci_platform_init_host() function, and inputs in the ahci_host_priv structure are now directly filed.

2014-07-30[media] xc5000: always write at dmesg when it fails to upload firmwareMauro Carvalho Chehab
On a normal condition, no errors should happen at xc5000 firmware upload is done. So, print at the dmesg if something bad happens. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] xc5000: optimize firmware retry logicMauro Carvalho Chehab
Currently, firmware retry logic keeps reading from FS every time during the retry logic. This is not needed. Instead, only release the firmware read after success. While here, make the non-debug messages less verbose, as it only matters to the user if the firmware was successfully loaded, or if some error happened.

2014-07-30[media] xc5000: Don't try forever to load the firmwareMauro Carvalho Chehab
With the current code, if something bad happens during the firmware init process, the device will keep trying forever, and removing it would cause an OOPS. Instead, try only a limited amount of time. If not, fails. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] au0828: add support for IR on HVR-950QMauro Carvalho Chehab
HVR-950Q uses an I2C remote controller at address 0x47 (7-bits notation). Add support for it. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] ir-rc5-decoder: print where decoding failsMauro Carvalho Chehab
The IR dprintk message that prints a RC5 decoding failure is not much helpful, as it doesn't tell on what bit the error occurred. Add such information, in order to make the debug message more useful. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] rc-main: allow raw protocol drivers to restrict the allowed protosMauro Carvalho Chehab
On some hardware (au0828/au8522), the hardware is broken with regards to the initial pulse detection. So, the driver needs to produce a fake start pulse. That limits the acceptable protocols, as it is not possible to produce a fake pulse that would cover all supported protocols. So, allow the driver to explicitly set the allowed protocols. If the driver doesn't specify, keep the old behavior. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] au0828: improve I2C speedMauro Carvalho Chehab
Commits 21dc61d3c0a4 and 7a1dd50b89d4 reduced the board I2C speed to 20 MHz by default, due to a I2C stretch issue: while xc5000 uses i2c stretch when a command is sent to it, au0828 doesn't support this feature. However, this is needed only for Xceive tuners. The other I2C devices can work at the max speed. So, revert the workarounds at board level, handling it at I2C level, only when talking with xc5000.

2014-07-30KVM: x86: always exit on EOIs for interrupts listed in the IOAPIC redir tablePaolo Bonzini
Currently, the EOI exit bitmap (used for APICv) does not include interrupts that are masked. However, this can cause a bug that manifests as an interrupt storm inside the guest. Alex Williamson reported the bug and is the one who really debugged this; I only wrote the patch. :) The scenario involves a multi-function PCI device with OHCI and EHCI USB functions and an audio function, all assigned to the guest, where both USB functions use legacy INTx interrupts. As soon as the guest boots, interrupts for these devices turn into an interrupt storm in the guest; the host does not see the interrupt storm. Basically the EOI path does not work, and the guest continues to see the interrupt over and over, even after it attempts to mask it at the APIC. The bug is only visible with older kernels (RHEL6.5, based on 2.6.32 with not many changes in the area of APIC/IOAPIC handling). Alex then tried forcing bit 59 (corresponding to the USB functions' IRQ) on in the eoi_exit_bitmap and TMR, and things then work. What happens is that VFIO asserts IRQ11, then KVM recomputes the EOI exit bitmap. It does not have set bit 59 because the RTE was masked, so the IOAPIC never sees the EOI and the interrupt continues to fire in the guest. My guess was that the guest is masking the interrupt in the redirection table in the interrupt routine, i.e. while the interrupt is set in a LAPIC's ISR, The simplest fix is to ignore the masking state, we would rather have an unnecessary exit rather than a missed IRQ ACK and anyway IOAPIC interrupts are not as performance-sensitive as for example MSIs. Alex tested this patch and it fixed his bug. [Thanks to Alex for his precise description of the problem and initial debugging effort. A lot of the text above is based on emails exchanged with him.] Reported-by: Alex Williamson <alex.williamson@redhat.com> Tested-by: Alex Williamson <alex.williamson@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-07-30Merge tag 'please-pull-apei' into x86/rasH. Peter Anvin
APEI is currently implemented so that it depends on x86 hardware. The primary dependency is that GHES uses the x86 NMI for hardware error notification and MCE for memory error handling. These patches remove that dependency. Other APEI features such as error reporting via external IRQ, error serialization, or error injection, do not require changes to use them on non-x86 architectures. The following patch set eliminates the APEI Kconfig x86 dependency by making these changes: - treat NMI notification as GHES architecture - HAVE_ACPI_APEI_NMI - group and wrap around #ifdef CONFIG_HAVE_ACPI_APEI_NMI code which is used only for NMI path - identify architectural boxes and abstract it accordingly (tlb flush and MCE) - rework ioremap for both IRQ and NMI context NMI code is kept in ghes.c file since NMI and IRQ context are tightly coupled. Note, these patches introduce no functional changes for x86. The NMI notification feature is hard selected for x86. Architectures that want to use this feature should also provide NMI code infrastructure.

2014-07-30Bluetooth: Fix SMP context tracking leading to a kernel crashJohan Hedberg
The HCI_CONN_LE_SMP_PEND flag is supposed to indicate whether we have an SMP context or not. If the context creation fails, or some other error is indicated between setting the flag and creating the context the flag must be cleared first. This patch ensures that smp_chan_create() clears the flag in case of allocation failure as well as reorders code in smp_cmd_security_req() that could lead to returning an error between setting the flag and creating the context.

Pull Exynos platform DT fix from Grant Likely: "Device tree Exynos bug fix for v3.16-rc7 This bug fix has been brewing for a while. I hate sending it to you so late, but I only got confirmation that it solves the problem this past weekend. The diff looks big for a bug fix, but the majority of it is only executed in the Exynos quirk case. Unfortunately it required splitting early_init_dt_scan() in two and adding quirk handling in the middle of it on ARM. Exynos has buggy firmware that puts bad data into the memory node. Commit 1c2f87c22566 ("ARM: Get rid of meminfo") exposed the bug by dropping the artificial upper bound on the number of memory banks that can be added. Exynos fails to boot after that commit. This branch fixes it by splitting the early DT parse function and inserting a fixup hook. Exynos uses the hook to correct the DT before parsing memory regions" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: arm: Add devicetree fixup machine function of: Add memory limiting function for flattened devicetrees of: Split early_init_dt_scan into two parts

With calling te mmu_notifier_register function we hold a reference to the mm_struct that needs to be released in mmu_notifier_unregister. This is true even if the notifier was already unregistered from exit_mmap and the .release call-back has already run. So make sure we call mmu_notifier_unregister unconditionally in amd_iommu_unbind_pasid. Signed-off-by: Joerg Roedel <jroedel@suse.de> Tested-by: Oded Gabbay <oded.gabbay@amd.com>
2014-07-30arm64: vdso: fix build error when switching from LE to BEArun Chandran
Building a kernel with CPU_BIG_ENDIAN fails if there are stale objects from a !CPU_BIG_ENDIAN build. Due to a missing FORCE prerequisite on an if_changed rule in the VDSO Makefile, we attempt to link a stale LE object into the new BE kernel. According to Documentation/kbuild/makefiles.txt, FORCE is required for if_changed rules and forgetting it is a common mistake, so fix it by 'Forcing' the build of vdso. This patch fixes build errors like these: arch/arm64/kernel/vdso/note.o: compiled for a little endian system and target is big endian failed to merge target specific data of file arch/arm64/kernel/vdso/note.o arch/arm64/kernel/vdso/sigreturn.o: compiled for a little endian system and target is big endian failed to merge target specific data of file arch/arm64/kernel/vdso/sigreturn.o Tested-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Arun Chandran <achandran@mvista.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
