Many embedded systems will not need this syscall, and omitting it
saves space.  Add a new EXPERT config option CONFIG_SENDFILE_SYSCALL
(default y) to support compiling it out.

I believe these options ought to be CONFIG_SYSCALL_*

I agree.  I think people started using CONFIG_*_SYSCALL because of
things like AUDITSYSCALL 

AUDITSYSCALL audits syscalls.  It doesn't actually implement any
syscalls.  You are right about SYSFS_SYSCALL though...
