X-Git-Tag: firefly_0821_release~33451^2~86
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=68bbc172cd1b0ee01814304b8a7bef8922d5fdca;p=firefly-linux-kernel-4.4.55.git

[PATCH] i386: remove redundant generic_identify() calls when identifying cpus

cpu_dev->c_identify is only called from arch/i386/common.c:identify_cpu(), and
this after generic_identify() already has been called. There is no need to call
this function twice and hook it in c_identify - but I may be wrong, please
double check before applying.

This patch also removes generic_identify() from cpu.h to avoid unnecessary
future nesting.
