Possible bug in sysdeps/unix/sysv/linux/powerpc/mmap64.c

[Jack Howarth]

HJ,
  I can't say why it is set to 12 but the PAGE_SHIFT is present in
sysdeps/unix/sysv/linux/powerpc/mmap64.c because the powerpc asm
headers in Linux 2.4.x were tightened to not export PAGE_SHIFT
(thus it had to be hardcoded into mmap64.c). I recall that the
idea was that it should never change no matter what happened to
PAGE_SHIFT in linux.      

Here is one message where the original idea was discussed.
