This patch removes the mca-pentium boot option that was a noop.

thanks Adrian, applied.

btw, it saved some text too:

 arch/x86/kernel/cpu/bugs.o:
   text    data     bss     dec     hex filename
    651      77       4     732     2dc bugs.o.before
    631      53       4     688     2b0 bugs.o.after

50 bytes - more than i expected.

btw., it would be nice if someone could try a "smallest possible, but 
still usable" x86 kernel.

the smallest one i could do, and which was still usable via the 
networking, is the config below. It has a vmlinux of:

     text    data     bss     dec     hex filename
  1330285  146512   69632 1546429  1798bd vmlinux

which is still rather large. The top cost is:

  83832    5878     516   90226   16072 ./mm/built-in.o
 142684    8524   29876  181084   2c35c ./kernel/built-in.o
