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.

Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/. We expect other similar drivers to get moved to the same place in order to avoid creating more top-level directories under drivers/ or cluttering up the messy drivers/misc/ even more." * tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) ARM: imx: reset_controller may be disabled ARM: mvebu: Align the internal registers virtual base to support LPAE ARM: mvebu: Limit the DMA zone when LPAE is selected arm: plat-orion: remove addr-map code arm: mach-mv78xx0: convert to use the mvebu-mbus driver arm: mach-orion5x: convert to use mvebu-mbus driver arm: mach-dove: convert to use mvebu-mbus driver arm: mach-kirkwood: convert to use mvebu-mbus driver arm: mach-mvebu: convert to use mvebu-mbus driver ARM i.MX53: set CLK_SET_RATE_PARENT flag on the tve_ext_sel clock ARM i.MX53: tve_di clock is not part of the CCM, but of TVE ARM i.MX53: make tve_ext_sel propagate rate change to PLL ARM i.MX53: Remove unused tve_gate clkdev entry ARM i.MX5: Remove tve_sel clock from i.MX53 clock tree ARM: i.MX5: Add PATA and SRTC clocks ARM: imx: do not bring up unavailable cores ARM: imx: add initial imx6dl support ARM: imx1: mm: add call to mxc_device_init ARM: imx_v4_v5_defconfig: Add CONFIG_GPIO_SYSFS ARM: imx_v6_v7_defconfig: Select CONFIG_PERF_EVENTS ... 2013-05-02T19:50:06+00:00 Arnd Bergmann arnd@arndb.de 2013-04-30T12:58:31+00:00 urn:sha1:5c5f0421a8eea5bdaba9b9313c5bb4833aeb39cd The new reset controller API is optional, so if that is disabled, we must not call it from platform code. arch/arm/mach-imx/built-in.o: In function `imx_src_init': /git/arm-soc/arch/arm/mach-imx/src.c:144: undefined reference to `reset_controller_register' Cc: Sascha Hauer <kernel@pengutronix.de> Signed-off-by: Arnd Bergmann <arnd@arndb.de> 2013-05-02T16:28:03+00:00 Linus Torvalds torvalds@linux-foundation.org 2013-05-02T16:28:03+00:00 urn:sha1:dfab34aa61a0f8c14a67d7b4c1dae28e57ba592d Pull ARM SoC device-tree updates from Olof Johansson: "Part 1 of device-tree updates for 3.10.
