From: Robert Richter Date: Tue, 20 Jul 2010 18:50:49 +0000 (+0200) Subject: x86, xsave: 32/64 bit boot cpu check unification in initialization X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db10db48b2c530def21bfd76d576702c7df7f620;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
