[Qemu-devel] [PULL 16/35] acpi: filter based on CONFIG_ACPI_X86 rather t


From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 16/35] acpi: filter based on CONFIG_ACPI_X86 rather than TARGET
Date: Fri, 20 Jan 2017 14:31:20 +0100

Copy the mechanism of hw/smbios/smbios-stub.c to implement an ACPI-stub
instead, so that -acpitable can be later extended to ARM.
