DESCRIPTION:
----------------------------------------------
## lnxi-patch-14 ##
src/mainboard/arima/hdama/mptable.c
Removed: max_apicid() renamed it to max_lapicid() and moved it into
generic code
/cpu/x86/lapic/lapic.c (See next)
src/cpu/x86/lapic/lapic.c
Added: generic max_lapicid() to replace get_apicid_base()
src/mainboard/.../mptable.c
Replaced: get_apicid_base() with max_lapicid()
