Solution to Nvidia + cairo-gl memory problem proposed by Nvidia

A small portion of that post from Nvidia:
"Attached is a proof-of-concept patch which fixes this issue for the x86_64 Linux ELF loader. By both applying this patch to the loader and prelinking libnvidia-glcore.so, distros can reduce the memory overhead of linking an application against the NVIDIA libGL to just a few kB:"

This is the same as bug #725434 which has been closed Won't Fix for the Nvidia drivers, figured it would be better to start over here that re-open that?

The attached patch is against eglibc.

The most interesting part of this bug would probably finding a good starting address for the NVIDIA GL libraries on x86, rather than the linker patch.

Status changed to 'Confirmed' because the bug affects multiple users.

[Pierre-Loup A. Griffais (1auntzpad-0ut)]

I had filed this bug against glibc to drive the patch in:

Note that the next major release from the NVIDIA driver includes a wrapper for most of the external calls, which should suppress the x86-specific relocation problem that I described in my original message to the list.

Note that my comment above didn't mean to imply the loader patch was unnecessary, both steps are needed to achieve optimal results.
