Default Re: 1.0-8178 for x86-64/em64t and x86 updates

The attached patch works around a bug in older Linux/x86-64 2.6 kernels with broken implementations of the change_page_attr() interface that can lead to kernel panics on Linux/x86-64 systems that either do not support the no-execute page protection feature or on which this feature has been disabled by the SBIOS. Affected is e.g. RHEL4's 2.6.9-5.EL kernel.

While this patch will prevent the kernel panics, the change_page_attr() interface will not be used on these kernels. This can lead to stability problems (see the section on Cache Aliasing in Appendix L. Known Issues of the Linux/x86-64 driver's README (http://download.nvidia.com/XFree86/L...ppendix-l.html) for details)). It is recommended that you upgrade your kernel to the distribution's latest update kernel or to the latest stable Linux 2.6 kernel.
