+Required missing symbols for FC11 kernels (2.6.29.4-167.fc11.x86_64)
+
+* get_vmalloc_info()
+There is no clean API in the kernel for modules to check the virtual
+memory state of the system.  This information is available in user
+space under /proc/meminfo and the details for every virtual memory
+node are available under /proc/vmallocinfo.
+
+* groups_search()
+This support is easily replicated if the symbol is not provided by the
+kernel.  However exporting the symbol from the kernel is preferable.
+This is required by the solaris credential API.
+
+* task_curr()
+This symbol is used by the solaris adaptive mutex implementation.  If
+unavailable then all solaris mutexs behave strictly like linux style
+semaphones.  If available then the mutex may spin for a short while,
+rather than sleep, if the holder of the lock is currently executing.
+
+* first_online_pgdat()
+* next_online_pgdat()
+* next_zone()
+Required helper functions for the zone iterators for_each_zone() and
+for_each_populated_zone().  These symbols were previously available
+in 2.6.17 kernels, marked unused in 2.6.18 kernels, and removed as
+of the 2.6.19 kernel series.  The information is available in user
+space under /proc/zoneinfo.
