This patch address several issues in the current BSD Secure Levels code:
o plaintext_to_sha1: Missing check for a NULL return from __get_free_page
o passwd_write_file: A page is leaked if the password is wrong.
o fix securityfs registration order
o seclvl_init is a mess and can't properly tolerate failures, failure
path is upside down (deldif and delf should be switched)
Cleanups:
o plaintext_to_sha1: Use buffers passed in
o passwd_write_file: Use kmalloc() instead of get_zeroed_page()
o passwd_write_file: hashedPassword comparison is just memcmp
o s/ENOSYS/EINVAL/
o misc
(akpm: after some discussion it appears that the BSD secure levels feature
should be scheduled for removal. But for now, let's fix these problems up).

settime() with a NULL timeval is silly but legal.

That should be -EINVAL for both.

We don't put braces around single statements, thanks.

Once again, the simple_attr in libfs was actually sufficient - I'd
thought the __attribute__(format(printk(1,2))) was more mysterious than
it really is.
At last, here is the full patch to make seclvl use securityfs.

This patch goes through the current users of the crypto layer and sets
CRYPTO_TFM_REQ_MAY_SLEEP at crypto_alloc_tfm() where all crypto operations
are performed in process context.

sysfs: fix the rest of the kernel so if an attribute doesn't
implement show or store method read/write will return
-EIO instead of 0 or -EINVAL or -EPERM.

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!
