ChangeSet Key: 4188122b4-5vHFkvfD5Pc0Egjyaz8w
======== ChangeSet 1.2424.7.12 ======== D 1.2424.7.12 04/11/02 15:03:07-08:00 ak@suse.de[torvalds] 53848 53847 3/0/1 P ChangeSet C [PATCH] x86_64: flex mmap patch for x86-64 C C From: Arjan van de Ven <arjanv@redhat.com> 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. C C Signed-off-by: Andrew Morton <akpm@osdl.org> C Signed-off-by: Linus Torvalds <torvalds@osdl.org> ------------------------------------------------
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.)
