svn commit: r329365 - head/sys/amd64/include

[Konstantin Belousov]

Author: kib
Date: Fri Feb 16 13:32:46 2018
New Revision: 329365
URL: https://svnweb.freebsd.org/changeset/base/329365

Log:
  Use local symbol for offset.
  
  Small global symbols confuse ddb which matches them against small
  unrelated displacements and makes the disassembly ugly.
