ouyangxiangzhen f7abf7446f arch/arm64: Optimized SGI to avoid VM exit. ... In the virtualized environment, each time an SGI is sent, the value of IGROUPR0 needs to be read once. Since the GIC Redistributor is a purely emulated device, each read of IGROUPR0 will cause a VM exit, causing serious performance degradation. This patch replaces the read with the value previously set in `gicv3_cpuif_init`, and we assume that this value has not been modified after initialization.
