Make sure we always return, as all syscalls should.  Also move the common
prototype to <linux/syscalls.h>

If we use 64bit kernel on ia64/x86_64/s390 architecture, and we run
32bit binary on 32bit compatibility mode, sendfile system call seems be
not set offset argument.

This is because sendfile's return value is not zero but the code regards
the result by return value is zero or not.

This problem will be affect to ia64/x86_64/s390 and not affect to other
architecture does not affect other architecture (mips/parisc/ppc64/sparc64).

64 bit architectures all implement their own compatibility sys_open(),
when in fact the difference is simply not forcing the O_LARGEFILE
flag.  So use the a common function instead.

This gets rid of an unused variable `error' in sys_ia32.c:sys32_epoll_wait()

Getting rid of this one makes parsing the output of the kernecomp
autobuild easier --- searching for `Error' to find a problem kept
hitting this one, even though it's only a warning.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
