Of course, mmap2 is for 32-bit ports. Ok, let me rephrase
1. All 32-bit ports should have the mmap2 system call and use
sysdeps/unix/sysv/linux/mmap64.c.
2. All 64-bit ports don't need mmap2 and should have a dummy
sysdeps/unix/sysv/linux/$arch/mmap64.c.
You have to provide a dummy mmap64.c for your 64-bit port today. With
my mmap64.c patch, all 32-bit ports can use the same mmap64.c unlike
today, each 32-bit port does the same thing for mmap64.c. It is
ridiculous.
