Russell King <rmk+lkml@arm.linux.org.uk> This construct is refused by GCC 4, so here's the (corrected) fix. Thanks to Russell for noticing a stupid mistake I did when first sending this. As he noted, the code is largely suboptimal however it currently works, and will be fixed shortly. Just read the access_ok check on fp which is NULL, or the pointer arithmetic below which should be done with a cast to void*: frame = (struct rt_sigframe __user *) round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8; The code shows clearly that has been taken from arch/x86_64/kernel/signal.c:setup_rt_frame(), maybe in a bit of a hurry.
