If the 'ptr' is a const, this code cause "assignment of read-only variable"
error on gcc 4.x.

Use __u64 instead of __typeof__(*(ptr)) for temporary variable to get
rid of errors on gcc 4.x.

I've rewriten Atushi's fix for the 64-bit put_unaligned on 32-bit systems
bug to generate more efficient code.

This case has buzilla URL http://bugzilla.kernel.org/show_bug.cgi?id=5138.

Turns __get_unaligned() and __put_unaligned into macros.  That is
definitely safe; leaving them as inlines breaks on e.g.  alpha [try to
build ncpfs there and you'll get unresolved symbols since we end up
getting __get_unaligned() not inlined].

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!
