2015-08-21crypto: hash - Add AHASH_REQUEST_ON_STACKHerbert Xu1-0/+5
This patch adds the helper AHASH_REQUEST_ON_STACK for those users of ahash that are synchronous only. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: testmgr - Use new skcipher interfaceHerbert Xu1-29/+32
This patch replaces uses of blkcipher and ablkcipher with the new skcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: skcipher - Add top-level skcipher interfaceHerbert Xu4-1/+651
This patch introduces the crypto skcipher interface which aims to replace both blkcipher and ablkcipher. It's very similar to the existing ablkcipher interface. The main difference is the removal of the givcrypt interface. In order to make the transition easier for blkcipher users, there is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place a request on the stack for synchronous transforms.

2015-08-21tools lib traceevent: Add checks for returned EVENT_ERROR typeDean Nelson1-0/+9
Running the following perf-stat command on an arm64 system produces the following result... [root@aarch64 ~]# perf stat -e kmem:mm_page_alloc -a sleep 1 Warning: [kmem:mm_page_alloc] function sizeof not defined Warning: Error: expected type 4 but read 0 Segmentation fault [root@aarch64 ~]# The second warning was a result of the first warning not stopping processing after it detected the issue. That is, code that found the issue reported the first problem, but because it did not exit out of the functions smoothly, it caused the other warning to appear and not only that, it later caused the SIGSEGV.

2015-08-21perf tools: Fix Intel PT timestamp handlingAdrian Hunter1-1/+1
Events that don't sample the timestamp have a timestamp value of -1. Intel PT processing wasn't taking that into account. This is particularly noticeable with Intel BTS because timestamps are not requested by default. Then, if the conversion of -1 to TSC results in a small number, the processing is unaffected. However if the conversion results in a big number, then the data is processed prematurely before relevant sideband data like mmap events, which in turn results in samples with unknown dsos. Commiter note: Since BTS wasn't upstream, I split the patch to fold the BTS part with the patch introducing it, to avoid having this bug in the commit history. PT was already upstream, so this patch contains that part.

2015-08-21perf tools: /proc/kcore requires CAP_SYS_RAWIO message too noisyAdrian Hunter2-2/+3
The "/proc/kcore requires CAP_SYS_RAWIO" message comes up all the time for 'perf script' if vmlinux is not found and the user isn't root, even when the kernel is not being traced and even though the message is only really relevant for annotation. Change it to pr_debug and instead put a note in the message displayed if annotation is not possible. Also, the file being accessed might not be /proc/kcore. Tools can be directed to a different location using the --kallsyms option in which case kcore is expected to be in the same directory. Adjust the message so it is not misleading in that case.

2015-08-21perf script: Fix segfault using --show-mmap-eventsAdrian Hunter1-1/+1
Patch "perf script: Don't assume evsel position of tracking events" changed 'perf script' to use 'perf_evlist__id2evsel()'. That results in a segfault if there is more than 1 event and there are synthesized mmap events e.g. $ perf record -e cycles,instructions -p$$ sleep 1 $ perf script --show-mmap-events Segmentation fault (core dumped) That happens because these synthesized events have an 'id' of zero which does not match any 'evsel'. Currently, these synthesized events use the sample type of the first evsel. Change 'perf_evlist__id2evsel()' to reflect that which also makes it consistent with 'perf_evlist__event2evsel()'.

2015-08-21PCI: Don't use 64-bit bus addresses on PA-RISCBjorn Helgaas1-1/+1
Meelis and Helge reported that 3a9ad0b4fdcd ("PCI: Add pci_bus_addr_t") caused HPMCs on A500 and hangs on rp5470. PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so prior to 3a9ad0b4fdcd, we always used 32-bit PCI addresses. After 3a9ad0b4fdcd, we do use 64-bit PCI addresses in 64-bit kernels, and apparently there's some PA-RISC problem related to them.

Previously we checked for invalid MPS settings, i.e., a device with MPS different than its upstream bridge, in pcie_bus_detect_mps(). We only did this if the arch or hotplug driver called pcie_bus_configure_settings(), and then only if PCIe bus tuning was disabled (PCIE_BUS_TUNE_OFF).

2015-08-20spi: ti-qspi: use 128 bit transfer mode where possibleVignesh R1-4/+30
TI QSPI has four 32 bit data regsiters which can be used to transfer 16 bytes of data at once. The register group QSPI_SPI_DATA_REG_3, QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is treated as a single 128-bit word for shifting data in and out. The bit at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out in case of 128 bit transfer mode. Therefore the first byte to be written to flash should be at QSPI_SPI_DATA_REG_3[31-25] position. Instead of writing 1 byte at a time when interacting with spi-nor flash, make use of all the four registers so that 16 bytes can be transferred in one go. This reduces number of register writes and Word Complete interrupts for a given transfer message size, thereby increasing the write performance. Without this patch the raw flash write speed is ~100KB/s, with this patch the write speed increases to ~400 kB/s on DRA74 EVM.

2015-08-20ARM/PCI, designware, xilinx: Use pci_scan_root_bus_msi()Lorenzo Pieralisi4-10/+20
ARM previously stored the msi_controller pointer in its sysdata, struct pci_sys_data, and implemented pcibios_msi_controller() to retrieve it. That made PCI host controller drivers specific to ARM because they had to put the msi_controller pointer in the ARM-specific pci_sys_data. There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the msi_controller pointer to the PCI core. Use this for all ARM systems and for the DesignWare and Xilinx PCI host controller drivers. This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6, Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

In the ARM PCI bios32 layer, failures to dynamically allocate pci_sys_data for a PCI bus, or a PCI bus scan failure have to be considered serious warnings but they should not trigger a system panic so that at least the system is given a chance to be debugged. This patch replaces the panic statements with WARN() messages to improve error reporting in the ARM PCI bios32 layer.

ARM64 requires setup-irq.o to provide pci_fixup_irqs() implementation. We are adding this now to support the pci-host-generic host controller, but we enable it for ARM64 PCI so that other host controllers can use this as well.

2015-08-20PCI: generic: Remove dependency on ARM-specific struct hw_pciJayachandran C1-19/+33
The generic OF-based host controller driver uses pci_common_init_dev(), which is ARM-specific and requires the ARM struct hw_pci. The part of pci_common_init_dev() that is needed is limited and can be done here without using hw_pci. Note that the ARM pcibios functions expect the PCI sysdata to be a pointer to a struct pci_sys_data. Add a struct pci_sys_data as the first element in struct gen_pci so that when we use a gen_pci pointer as sysdata, it is also a pointer to a struct pci_sys_data. Create and scan the root bus directly without using the ARM pci_common_init_dev() interface.

Since commit feb44f1f7a4ac299d1ab1c3606860e70b9b89d69 (x86/xen: Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need a full APIC driver and thus should depend on X86_LOCAL_APIC. This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by disabling Xen support in this configuration.

2015-08-20irqchip/crossbar: Restore set_wake functionalityGrygorii Strashko1-2/+2
The TI crossbar irqchip doesn't provides any facility to configure the wakeup sources, but the conversion to hierarchical irqdomains set the irq_set_wake callback to irq_chip_set_wake_parent. The parent chip (OMAP wakeupgen) has no irq_set_wake function either so the call will fail with -ENOSYS. As a result the irq_set_wake() call in the resume path will trigger an 'Unbalanced wake disable' warning. Before the conversion the GIC irqchip was the top level irqchip and correctly flagged with IRQCHIP_SKIP_SET_WAKE. Restore the correct behaviour by removing the irq_set_type callback from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which lets the irq_set_irq_wake() call from the driver succeed.

2015-08-20irqchip/crossbar: Restore the mask on suspend behaviourGrygorii Strashko1-0/+1
The ARM GIC requires that all interrupts which are not used as a wakeup source have to be masked during suspend. The conversion of the crossbar irqchip to hierarchical irq domains failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND flag and therefor broke the suspend requirement of the GIC. Before the conversion the flags were visible because the GIC was the top level irqchip. After the conversion the crossbar irqchip is the top level irq chip whose flags are evaluated in suspend_device_irq(). As the flag is not set the masking of the non-wakeup irqs is not invoked which breaks suspend. Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the GIC interrupts get masked properly.

2015-08-20ARM: OMAP: wakeupgen: Restore the irq_set_type() mechanismGrygorii Strashko1-0/+1
The conversion of the wakeupgen irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The wakeupgen irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the wakeupgen irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.
