Subject: x86, acpi: Add MAX_LOCAL_APIC for 32bit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=56d91f132c9be66e98cce1b1e77a28027048bb26;p=linux-beck.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.
