+This patch will work on installers for version 304.108 of the NVIDIA
+Linux driver.
+
+It will not apply cleanly against older 304 drivers, but can be made to

++#define NV_PATCH_get_num_physpages_DESCRIPTION \
++"This patch adds support for kernels such as Linux 3.11, which use the "\
++"get_num_physpages() function instead of the num_physpages variable to "\
++"report the number of physical pages. In order to avoid compatibility "\
++"problems that would otherwise result from differences between what "\
++"the removed num_physpages variable reported versus what is reported "\
++"by get_num_physpages(), the driver will fall back to a different memory "\
++"allocation strategy on systems where num_phsypages is not available, when "\
++"the amount of system memory matches or exceeds the upper bound of a given "\
++"GPU's physical address space.\n"
