The ARM64-SMP code skips the disabled GICC entries but not causing any issue. However the current GICv3 driver probe bails out causing kernel panic() instead of skipping the disabled GICC interfaces. This issue happens on systems where redistributor regions are not in the always-on power domain and one of GICC interface marked with ACPI_MADT_ENABLED=0.

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Mon Apr 9 10:16:32 CEST 2018 From: Hans de Goede <hdegoede(a)redhat.com> Date: Fri, 12 Jan 2018 00:36:48 -0800 Subject: Input: goodix - disable IRQs while suspended From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit faec44b6838312484d63e82286087cf2d5ebb891 ] We should not try to do any i2c transfers before the controller is resumed (which happens before our resume method gets called). So we need to disable our IRQ while suspended to enforce this. The code paths for devices with GPIOs for the int and reset pins already disable the IRQ the through goodix_free_irq(). This commit also disables the IRQ while suspended for devices without GPIOs for the int and reset pins. This fixes the i2c bus sometimes getting stuck after a suspend/resume causing the touchscreen to sometimes not work after a suspend/resume. This has been tested on a GPD pocked device.

This allows us to properly free queue memory and shut down things before we request the hardware reset. It turns out that we cannot be guaranteed of netif_running() returning false until the device is fully up, as the kernel core code sets __LINK_STATE_START prior to calling .ndo_open. Since we're not holding the rtnl_lock(), it's possible that the driver's i40evf_open handler function is currently being called while we're resetting. We can't simply hold the rtnl_lock() while checking netif_running() as this could cause a deadlock with the i40evf_open() function. Additionally, we can't avoid the deadlock by holding the rtnl_lock() over the whole reset path, as this essentially serializes all resets, and can cause massive delays if we have multiple VFs on a system. Instead, lets just check our own internal state __I40EVF_RUNNING state field. This allows us to ensure that the state is correct and is only set after we've finished bringing the device up. Without this change we might free data structures about device queues and other memory before they've been fully allocated.
