* ENGR00291086 crypto kernel module speed test in single failJay Monkman2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tcrypt module is used to test the crypto API by being passed a mode=<value> during module load. The test runs to completion before insmod/modprobe returns. That makes the RCU stall detection in newer kernels unhappy. The simple fix is to add CONFIG_PREEMPT to the kernel config. That's what this patch does. If that introduces other problems, crypto/tcrypt.c can be modified to call schedule() in the correct places.

* ENGR00295184-2 dts: imx6qdl-sabreauto: use external vmmc for sd3 optionallyDong Aisheng2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | SD3.0 cards require power cycle the card during suspend/resume, or the card re-enumeration after resume will fail to be identified as UHS card since the card is already working on 1.8v mode and refuse to ack the S18R request, thus, it will then work on normal high speed mode instead. We have to use external vmmc regulator to power cycle the card during suspend/resume to reset card signal voltage to 3.3v frist for the later 1.8v voltage switch. However, due to the sabreauto board limitation, we can not use external regulator to powere off card by default since the card power is shared with card detect pullup. Disabling the vmmc regulator will also shutdown the cd pullup which causes incorrect illusion of card exist. (e.g. plug out the card, mmc core wll think the card is exist since cd pin is low but it never can find the card) HW rework removing R695 and enable PAD internal pullup is needed to fix this isssue. User can manually open the mask of vmmc in dts to enable using external regulator if your board has done the rework as said above. Or by default we still do not power off card during suspend.

* ARM: pci: add ->add_bus() and ->remove_bus() hooks to hw_pciThomas Petazzoni2014-04-16
| | | | | | | | | | | | | | | | | | | | | Some PCI drivers may need to adjust the pci_bus structure after it has been allocated by the Linux PCI core. The PCI core allows architectures to implement the pcibios_add_bus() and pcibios_remove_bus() for this purpose. This commit therefore extends the hw_pci and pci_sys_data structures of the ARM PCI core to allow PCI drivers to register ->add_bus() and ->remove_bus() in hw_pci, which will get called when a bus is added or removed from the system. This will be used for example by the Marvell PCIe driver to connect a particular PCI bus with its corresponding MSI chip to handle Message Signaled Interrupts.

* ARM: integrator: merge PCIv3 driver into one fileLinus Walleij2014-04-16
| | | | | | | | | | | | | | | | | | The Integrator/AP PCI bridget, "v3" is contained in two files, where pci.c is a socket container to plug in the v3 device. However to transition the v3 to enable device tree probing, it need to be converted to a platform device (so that it can have a device node in the device tree) and then we want the PCI driver in a single file, as any other device driver, so we can handle variants using compatible strings and device name, and get the base address etc from resources connected to the device node. To move toward this goal we consolidate all code in the pci_v3.c file. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* ARM: imx: remove imx_src_prepare_restart() callShawn Guo2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is ~10% possibility that the following emergency restart command fails to reboot imx6q. $ echo b > /proc/sysrq-trigger The IMX restart routine mxc_restart() assumes that it will always run on primary core, and will call imx_src_prepare_restart() to disable secondary cores in order to get them come to online in the following boot. However, the assumption is only true for normal kernel_restart() case where migrate_to_reboot_cpu() will be called to migrate to primary core, but not necessarily true for emergency_restart() case. So when emergency_restart() calls into mxc_restart() on any secondary core, system will hang immediately once imx_src_prepare_restart() is called to disabled secondary cores. Since emergency_restart() is defined as a function that is safe to call in interrupt context, we cannot just call migrate_to_reboot_cpu() to fix the issue. Fortunately, we just found that the issue can be fixed at imx6q platform level. We used to call imx_src_prepare_restart() to disable all secondary cores before resetting hardware. Otherwise, the secondary will fail come to online in the reboot. However, we recently found that after commit 6050d18 (ARM: imx: reset core along with enable/disable operation) comes to play, we do not need to reset the secondary cores any more. That said, mxc_restart() now can run on any core to reboot the system, as long as we remove the imx_src_prepare_restart() call from mxc_restart(). So let's simply remove imx_src_prepare_restart() call to fix the above emergency restart failure.
