It looks reasonable to me too. I checked through VM_MAYflag handling and don't expect surprises (a few places already turn off VM_MAYWRITE in much the same way that this does, I hadn't realized). I'm disappointed to find that our mmap() is lax about checking its PROT and MAP args, so old kernels will accept PROT_FINAL but do nothing with it. Luckily mprotect() is stricter, so that can be used to check for whether it's supported. The patch does need to be slightly extended though: alpha, mips, parisc and xtensa have their own include/asm/mman.h, which does not include asm-generic/mman-common.h at all.
