[PATCH] Fix the warning when running make tags

[Aneesh Kumar K.V]

From: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxxxxxxx>


make tags was giving the below warning.

ctags: Warning: arch/x86_64/kernel/head.S:124: null expansion of name
pattern "\1"

Fix the same by making sure we taken only ENTRY pattern found at the
begining of the line.
