[PATCH 049/114] x86, es7000: clean up es7000_enable_apic_mode()

From: Ingo Molnar
Date: Wed Jan 28 2009 - 19:04:39 EST


- eliminate the needless es7000_enable_apic_mode() complication which
was not apparent prior the namespace cleanups

- clean up the control flow in es7000_enable_apic_mode()

- other cleanups
