From db10db48b2c530def21bfd76d576702c7df7f620 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Tue, 20 Jul 2010 20:50:49 +0200 Subject: x86, xsave: 32/64 bit boot cpu check unification in initialization 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.
