svn commit: r189066 - head/sys/kern

[Ed Schouten]

Author: ed
Date: Thu Feb 26 12:12:34 2009
New Revision: 189066
URL: http://svn.freebsd.org/changeset/base/189066

Log:
  Remove redundant assignment of `p'.
  
  `p' is already initialized with `td->td_proc'. Because td is always
  curthread, it is safe to initialize it without any locks.
