C [PATCH] x86_64: flex mmap patch for x86-64
C
C From: Arjan van de Ven <arjanv@xxxxxxxxxx>
C
C Do flex mmap for x86-64.  mmaps will grow down in the address space now
C instead of up.
C
C Patch has 2 parts; the generic strategy selection, and code to make a correct
C TASK_SIZE .  the later may be fixed in your tree already in which case it's
C redundant.
C
C Modified by AK to apply to 64bit processes too.

------------------------------------------------

This prevents 32bit apps from running on x86_64.  Backing out the Makefile
and processor.h changes has everything working again.  Perhaps something
needs to check for a 32bit environment?  I don't know if it's the change
to TASK_SIZE or the "backwards" mmaps that's the real breakage.  And at this
point, I don't have time to test.

(64bit apps work just fine.)
