+         * Problem (observed with channel DMAIC_7): after enabling the channel
+         * and initialising buffers, there comes an interrupt with current still
+         * pointing at buffer 0, whereas it should use buffer 0 first and only
+         * generate an interrupt when it is done, then current should already
+         * point to buffer 1. This spurious interrupt also comes on channel
+         * DMASDC_0. With DMAIC_7 normally, is we just leave the ISR after the
+         * first interrupt, there comes the second with current correctly
+         * pointing to buffer 1 this time. But sometimes this second interrupt
+         * doesn't come and the channel hangs. Clearing BUFx_RDY when disabling
+         * the channel seems to prevent the channel from hanging, but it doesn't
+         * prevent the spurious interrupt. This might also be unsafe. Think
+         * about the IDMAC controller trying to switch to a buffer, when we
+         * clear the ready bit, and re-enable it a moment later.

+        help
+          Enable this driver to get read/write support to most I2C EEPROMs,
+          after you configure the driver to know about each EEPROM on
+          your target board.  Use these generic chip names, instead of
+          vendor-specific ones like at24c64 or 24lc02:
+
+             24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,

+
+          Unless you like data loss puzzles, always be sure that any chip
+          you configure as a 24c32 (32 kbit) or larger is NOT really a
+          24c16 (16 kbit) or smaller, and vice versa. Marking the chip
+          as read-only won't help recover from this. Also, if your chip
+          has any software write-protect mechanism you may want to review the
+          code to make sure this driver won't turn it on by accident.
+
+          If you use this with an SMBus adapter instead of an I2C adapter,
+          full functionality is not available.  Only smaller devices are
+          supported (24c16 and below, max 4 kByte).
+

+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.
