- Enable this driver to get read/write support to most I2C EEPROMs,

- your target board. Use these generic chip names, instead of
- vendor-specific ones like at24c64 or 24lc02:

-
- 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).

+ 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,
+ 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024
+
+ 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).
+
+ This driver can also be built as a module. If so, the module
+ will be called at24.

+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.
