New Revision: 324303
URL: https://svnweb.freebsd.org/changeset/base/324303

Log:
  On amd64, mark the set_user_ldt() function as static.
  
  On i386, the function is used from the context switch code and needs
  to be accessible externally.  Amd64 MD context switch does not lock an
  LDT spinlock and inlines switching in assembly.
