Benjamin Herrenschmidt 547ee84cea [PATCH] ppc64: Improve mapping of vDSO 
This patch reworks the way the ppc64 is mapped in user memory by the kernel
to make it more robust against possible collisions with executable
segments.  Instead of just whacking a VMA at 1Mb, I now use
get_unmapped_area() with a hint, and I moved the mapping of the vDSO to
after the mapping of the various ELF segments and of the interpreter, so
that conflicts get caught properly (it still has to be before
create_elf_tables since the later will fill the AT_SYSINFO_EHDR with the
proper address).

While I was at it, I also changed the 32 and 64 bits vDSO's to link at
their "natural" address of 1Mb instead of 0.  This is the address where
they are normally mapped in absence of conflict.  By doing so, it should be
possible to properly prelink one it's been verified to work on glibc.
