I don't know. It looks like the RESTORE2 macro is extended with a nop 
operator in this patch. This looks like assembly code.

The thing that puzzles me most is that the current code looks like the 
following.

#define RESTORE(name, syscall) RESTORE2(name, syscall)
#define RESTORE2(name, syscall) \
__asm__ (                                               \
         "nop\n"                                         \
         ".text\n"                                       \
         "__" #name ":\n"                                \
         "       movq    $" #syscall ", %rax\n"          \
         "       syscall\n"                              \
);

So it looks like the patch has already been applied. Very definitely 
ddrown has not started from the same codebase, so I would be very 
reluctant to follow this path.

cheers
