The patch titled
lguest: ld.so on FC7 is mmap'ing shared libraries right in over guest memory
has been removed from the -mm tree. Its filename was
lguest-ldso-on-fc7-is-mmaping-shared-libraries-right-in-over-guest-memory.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: lguest: ld.so on FC7 is mmap'ing shared libraries right in over guest memory
From: Ronald G. Minnich <rminnich@xxxxxxxxx>
[ FC7 maps shared libraries very low, where the launcher maps guest's physical
memory. Quick fix is to link Launcher static, real fix is for 2.6.24. ]
-static is a simple fix. I expect this problem will be more common than we
like, as different distro's make different "improvements" to ld.so
[Arjan said:
this description is incorrect; it's not an ld.so change that causes the
low mapping.
It's a command line option to the prelink program (which is in most
distributions) that makes it use the entire address space, not just the
higher bits...."]
