From: Huacai Chen <chenhua...@loongson.cn> Now VIRT_GED_CPUHP_ADDR is not aligned to 4 bytes, but if Linux kernel is built with ACPI_MISALIGNMENT_NOT_SUPPORTED, it assumes the alignment, otherwise we get ACPI errors at boot phase:
ACPI Error: AE_AML_ALIGNMENT, Returned by Handler for [SystemMemory] (20250404/evregion-301) ACPI Error: Aborting method \_SB.CPUS.CSTA due to previous error (AE_AML_ALIGNMENT) (20250404/psparse-529) ACPI Error: Aborting method \_SB.CPUS.C000._STA due to previous error (AE_AML_ALIGNMENT) (20250404/psparse-529) ACPI Error: Method execution failed \_SB.CPUS.C000._STA due to previous error (AE_AML_ALIGNMENT) (20250404/uteval-68) VIRT_GED_MEM_ADDR and VIRT_GED_REG_ADDR are already aligned now, but use QEMU_ALIGN_UP() to explicitly align them can make code more robust.
