 +===== CONFIG_FRAME_WARN ===== 
 +This kernel configuration option passes an option to the compiler to cause it to emit a warning when a static stack size for a routine is detected that is larger than the specified threshold. It requires gcc version 4.4 or later in order to work.
 + 
 +The gcc option used is "-Wframe-larger-than=xxx". 
 +
 +By default, CONFIG_FRAME_WARN has the value of **1024**, but you can set it to any value from 0 to 8192.
 + 
 +Here is a sample of build output with this option configured to 256: 
 +    ...
 +    CC      ipc/msg.o
 +    CC      ipc/sem.o
 +    .../linux-3.0.y/ipc/sem.c: In function 'semctl_main.clone.7':
 +    .../linux-3.0.y/ipc/sem.c:1021:1: warning: the frame size of 520 bytes is larger than 256 bytes
