sys_mmap2 on different architectures
I've looked through the code for sys_mmap2 on several architectures, and it looks like some architectures plays by the "shift is always 12" rule, e.g. SPARC, and some expect userspace to actually obtain the page size, e.g. PowerPC and MIPS. On some architectures, e.g. x86 and ARM, the point is moot since PAGE_SIZE is always 2^12. a. Is this correct, or have I misunderstood
