Modified Files: src/sys/arch/aarch64/aarch64: cpu.c cpufunc.c cpufunc_asm_armv8.S src/sys/arch/aarch64/include: cpu.h cpufunc.h Log Message: Switch the Icache sync operation to the necessary and sufficient one according to the CTR_EL0.DIC and CTR_EL0.IDC flags. If CTR_EL0.DIC=1, Icache invalidation is not required. If CTR_EL0.IDC=1, Dcache clean before Icache invalidation is not required. CLIDR_EL1.LoC is 0, or CLIDR_EL1.LoUIS and CLIDR_EL1.LoUU are 0, Dcache clean is not required as well.
