gfp_t is a bitwise type, casting to unsigned long produces a warning. Suppress it with __force.
Otherwise sparse complains thusly: include/linux/kmemtrace.h:33:2: warning: cast from restricted gfp_t
Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> --- Eduard, this is a local patch I've had sitting around in my sparse testing tree. I'm really not sure what the appropriate format specifier is for a gfp_t, but I don't think the trace infrastructure has support for it anyway...so if you are going to keep casting to unsigned long you'll need this...perhaps with a comment why added.
