This kernel patch is no longer needed, with the change I made to init

and free...

-I have a version of free I wrote for BusyBox that uses sysinfo (rather then
-/proc) to get its information.  Under 2.2.x it reports normal stuff, i.e.
-    [andersen@dillweed busybox]$ ./free
-                  total         used         free       shared      buffers
-      Mem:       127800       124268         3532        16956         7544
-     Swap:       128516        13584       114932

-while under 2.2.0-test1-ac7 it reports wierd numbers (~ #/4096)
-    [andersen@dillweed busybox]$ ./free
-                  total         used         free       shared      buffers

-After investigating the problem, it turns out that somewhere during 2.3.x the
-values for memory stored in struct sysinfo changed from being stored as bytes
-to being units of PAGE_SIZE, but kernel/info.c was never updated to reflect
-this change in definition.
-
-Breaking free isn't that big of a deal, but I also use sysinfo in init to check
-that the box has enough ram from within the init process (and no, mounting
-/proc from within init and reading /proc/meminfo is not a good solution.
-BusyBox is often used in embedded systems where /proc is not compiled in).
-
-The following patch reinstates the traditional sysinfo(2) interface by
-returning bytes (not units of PAGE_SIZE) for memory values.
-
-An additional patch suggestion (not included here) would be to eliminate the
-supurfluous "mem_unit" variable from struct_sysinfo in include/linux/kernel.h
-and arch/*/mm/init.c.
