Log Message:
Pull up revision 1.242 (via patch, requested by sommerfeld):
  Add %fs/%gs to trap frame and save/restore them on trap/interupt/
  syscall entry from userspace.

  Remove special-case ``by hand'' validation of %fs/%gs register
  values s well as special handling of them in various signal
  handling paths.  Now, like %ds and %es, they are validated by
  the hardware on return to userland.

  This paves the way for the use of %fs for per-cpu data on multi-
  processor systems, and fixes an otherwise difficult-to-fix
  interaction between threads/clone(2) and USER_LDT.
