[PATCH 0/4] Keys patches

[David Howells <dhowells@redhat.com>]

Hi Linus, James,

Here are some more keyrings fixes plus some module signing documentation (if
you want it).  They can be found here also:

	http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=keys-devel

There are four items:

 (1) A patch to fix X.509 certificate gathering.  The problem was that I was
     coming up with a different path for signing_key.x509 in the build
     directory if it didn't exist to if it did exist.  This meant that the
     X.509 cert container object file would be rebuilt on the second rebuild in
     a build directory and the kernel would get relinked.

 (2) Unconditionally remove files generated by SYSTEM_TRUSTED_KEYRING=y when
     doing make mrproper.

 (3) Actually initialise the persistent-keyring semaphore for init_user_ns.  I
     have no idea why this works at all for users in the base user namespace
     unless it's something to do with systemd containerising the system.

 (4) Documentation for module signing.  Do you want this now or the next merge
     window?

David
