Subject: x86, acpi: Add MAX_LOCAL_APIC for 32bit
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=56d91f13;p=openwrt%2Fstaging%2Fblogic.git

x86, acpi: Add MAX_LOCAL_APIC for 32bit

We should use MAX_LOCAL_APIC for max apic ids and MAX_APICS as number
of local apics.

Also apic_version[] array should use MAX_LOCAL_APICs.
