Move the lowmemorykiller.txt into the actual source file which is really the
correct place for it, and delete lowmemorykiller.txt.

 /* drivers/misc/lowmemorykiller.c
+ *
+ * The lowmemorykiller driver lets user-space specify a set of memory thresholds
+ * where processes with a range of oom_adj values will get killed. Specify the
+ * minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the
+ * number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both
+ * files take a comma separated list of numbers in ascending order.
+ *
+ * For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
+ * "1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes
+ * with a oom_adj value of 8 or higher when the free memory drops below 4096 pages
+ * and kill processes with a oom_adj value of 0 or higher when the free memory
+ * drops below 1024 pages.
+ *
+ * The driver considers memory used for caches to be free, but if a large
+ * percentage of the cached memory is locked this can be very inaccurate
+ * and processes may not get killed until the normal oom killer is triggered.
