Arnd Bergmann 30766f1105 sh: rework sync_file_range ABI ... The unusual function calling conventions on SuperH ended up causing sync_file_range to have the wrong argument order, with the 'flags' argument getting sorted before 'nbytes' by the compiler. In userspace, I found that musl, glibc, uclibc and strace all expect the normal calling conventions with 'nbytes' last, so changing the kernel to match them should make all of those work. In order to be able to also fix libc implementations to work with existing kernels, they need to be able to tell which ABI is used. An easy way to do this is to add yet another system call using the sync_file_range2 ABI that works the same on all architectures. Old user binaries can now work on new kernels, and new binaries can try the new sync_file_range2() to work with new kernels or fall back to the old sync_file_range() version if that doesn't exist.
