BACKPORT: FROMGIT: irqchip/gic-v3: Workaround for GIC-700 erratum 2941627 GIC700 erratum 2941627 may cause GIC-700 missing SPIs wake requests when SPIs are deactivated while targeting a sleeping CPU - ie a CPU for which the redistributor: GICR_WAKER.ProcessorSleep == 1 This runtime situation can happen if an SPI that has been activated on a core is retargeted to a different core, it becomes pending and the target core subsequently enters a power state quiescing the respective redistributor. When this situation is hit, the de-activation carried out on the core that activated the SPI (through either ICC_EOIR1_EL1 or ICC_DIR_EL1 register writes) does not trigger a wake requests for the sleeping GIC redistributor even if the SPI is pending. Work around the erratum by de-activating the SPI using the redistributor GICD_ICACTIVER register if the runtime conditions require it (ie the IRQ was retargeted between activation and de-activation).

BEST: Make all of your changes to upstream Linux. If appropriate, backport to the stable releases. These patches will be merged automatically in the corresponding common kernels. If the patch is already in upstream Linux, post a backport of the patch that conforms to the patch requirements below.
EXPORT_SYMBOL_GPL()
require an in-tree modular driver that uses the symbol -- so include the new driver or changes to an existing driver in the same patchset as the export.LESS GOOD: Develop your patches out-of-tree (from an upstream Linux point-of-view). Unless these are fixing an Android-specific bug, these are very unlikely to be accepted unless they have been coordinated with kernel-team@android.com. If you want to proceed, post a patch that conforms to the patch requirements below.
