…lbacks

Under linux, if SELinux is enabled (i.e. not permisive or disabled), then the heap memory allocated with vmalloc() and marked as executable with mprotect() will fail. In order to have this work with SELinux enabled (and not providing a module policy file to allow execheap) mmap() should be used.

Note, it might be possible to remove the stdlib.h and sys/mman.h header file references.
