trafgen: setup_shared_var: fix couple of things
1) Fix a couple of sparse warnings: trafgen.c:382:27: error: cannot size expression trafgen.c:391:33: error: cannot size expression trafgen.c:393:33: error: cannot size expression trafgen.c:401:25: error: cannot size expression 2) Use MAP_FAILED instead of (void *) -1 3) No need to cast to void * on mmap(2) 4) Use NULL instead of 0 as mmap(2)'s first argument Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

rks a PTE inaccessible it clears all the protection bits but leave the PTE valid. With the Radix MMU, an attempt at executing from such a PTE will take a fault with bit 35 of SRR1 set "SRR1_ISI_N_OR_G". It is thus incorrect to treat all such faults as errors. We should pass them to handle_mm_fault() for autonuma to deal with. The case of pages that are really not executable is handled by the existing test for VM_EXEC further down. That leaves us with catching the kernel attempts at executing user pages. We can catch that earlier, even before we do find_vma. It is never valid on powerpc for the kernel to take an exec fault to begin with. So fold that test with the existing test for the kernel faulting on kernel addresses to bail out early.
