 * Using udelay() for intervals greater than a few milliseconds can
-
 
18
 * risk overflow for high loops_per_jiffy (high bogomips) machines. The
-
 
19
 * mdelay() provides a wrapper to prevent this.  For delays greater
-
 
20
 * than MAX_UDELAY_MS milliseconds, the wrapper is used.  Architecture
-
 
21
 * specific values can be defined in asm-???/delay.h as an override.

22
 * The 2nd mdelay() definition ensures GCC will optimize away the 
-
 
23
 * while loop for the common cases where n <= MAX_UDELAY_MS  --  Paul G.
