From: Jean Delvare Date: Tue, 3 Oct 2017 09:47:27 +0000 (+0200) Subject: x86/boot: Spell out "boot CPU" for BP X-Git-Tag: v4.15-rc1~156^2~2 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=a1652bb8a01c1a830cacbe958aec17f880cc1e47;p=linux.git x86/boot: Spell out "boot CPU" for BP It's not obvious to everybody that BP stands for boot processor. At least it was not for me. And BP is also a CPU register on x86, so it is ambiguous. Spell out "boot CPU" everywhere instead.
