[PATCH 02/10] x86, xsave: 32/64 bit boot cpu check unification in initialization

From: Robert Richter
Date: Tue Jul 20 2010 - 14:59:52 EST


Boot cpu id is always 0, thus simplifying and unifying boot cpu check.

boot_cpu_id is there for historical reasons and was renamed to
boot_cpu_physical_apicid in patch:

c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid

However, there are some remaining occurrences of boot_cpu_id that are
never touched in the kernel and thus its value is always 0.
