c/r rebase to 2.6.33-rc5

c/r rebase to 2.6.33-rc5

[Oren Laadan]

I rebased the most recent patchset to 2.6.33, and pushed to
ckpt-v19-rc2.10. only x86-32 is (lightly) tested.

it does not include patches from 1/27 and on. working on it
now.

please review:

* arch-specific parts that I didn't screw up anything.
btw, I moved checkpoint code from mm/ to kernel/

* [dan] network: net/checkpoint.c now uses sock_alloc_file();
there may or may not be a leak of sock_hold().

* [serge] selinux now auto-generates some include files, see
the changes to classmap.h

For x86-64, I needed the following patch.  With this patch, only
the fileio and futex tests failed.  Suka is looking into the fileio
failure - Matt you might check the futex tests on whatever arch
you have available...

For s390, I of course still need
"fix 31-bit s390 checkpoint/restart wrappers" for compile with
CONFIG_COMPAT to succeed.

Ok, fixed, and pushed to ckpt-v19-rc2.10.
If this is more or less ok, I'll change it to ckpt-v19-rc3 :)

My git tree isn't happy with whatever rebasing you did.  Can
you push a ckpt-v19-rc2.11 tag or just ckpt-v19-rc3?

I haven't looked at the selinux issue at all yet btw, and I'd
like to hear if anyone has figured out the issue with a pipe
being treated as Unlinked file in the robust futex testcase.
Matt?

SELinux tests pass, as do Smack tests.  No changes needed.

Thanks!
