Patch "arm64: kernel: restrict /dev/mem read() calls to linear region" has been added to the 4.9-stable tree

This is a note to let you know that I've just added the patch titled arm64: kernel: restrict /dev/mem read() calls to linear region to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm64-kernel-restrict-dev-mem-read-calls-to-linear-region.patch and it can be found in the queue-4.9 subdirectory.

The reason for the storm of interrupts is that the PUS field of register IOMUXC_SW_PAD_CTL_PAD_CSI0_DAT5 is currently configured as: 10 : 100k pullup and the PMIC interrupt is being registered as IRQ_TYPE_LEVEL_HIGH type, which is the correct type as per the MC34708 datasheet. Use the default power on value for the IOMUX, which sets PUS field as: 00: 360k pull down This prevents the spurious PMIC interrupts from happening. Commit e1ffceb078c6 ("ARM: imx53: qsrb: fix PMIC interrupt level") correctly described the irq type as IRQ_TYPE_LEVEL_HIGH, but missed to update the IOMUX of the PMIC GPIO as pull down.
