A while back we added the PR_SET_NAME prctl, but no PR_GET_NAME. I guess
we should add this, if only to enable testing of PR_SET_NAME.

The feature set the patch includes:
- Key attributes:
- Key type
- Description (by which a key of a particular type can be selected)
- Payload
- UID, GID and permissions mask
- Expiry time
- Keyrings (just a type of key that holds links to other keys)
- User-defined keys
- Key revokation
- Access controls
- Per user key-count and key-memory consumption quota
- Three std keyrings per task: per-thread, per-process, session
- Two std keyrings per user: per-user and default-user-session
- prctl() functions for key and keyring creation and management
- Kernel interfaces for filesystem, blockdev, net stack access
- JIT key creation by usermode helper
There are also two utility programs available:
(*) http://people.redhat.com/~dhowells/keys/keyctl.c
A comprehensive key management tool, permitting all the interfaces
available to userspace to be exercised.
(*) http://people.redhat.com/~dhowells/keys/request-key
An example shell script (to be installed in /sbin) for instantiating a
key.

This patch adds a prctl to modify current->comm as shown in /proc. This
feature was requested by KDE developers. In KDE most programs are started by
forking from a kdeinit program that already has the libraries loaded and some
other state.
Problem is to give these forked programs the proper name. It already writes
the command line in the environment (as seen in ps), but top uses a different
field in /proc/pid/status that reports current->comm. And that was always
"kdeinit" instead of the real command name. So you ended up with lots of
kdeinits in your top listing, which was not very useful.
This patch adds a new prctl PR_SET_NAME to allow a program to change its comm
field.
I considered the potential security issues of a program obscuring itself with
this interface, but I don't think it matters much because a program can
already obscure itself when the admin uses ps instead of top. In case of a
KDE desktop calling everything kdeinit is much more obfuscation than the
alternative.

Here is both a GNU style and BK patch for adding support for the e500 core and
85xx platform to 2.6. This is pretty much a direct port from 2.4 with a bit
of cleanup around the edges.

programs to select whether they use statistical time accounting
or accurate timestamp based accounting.

This patch that adds a prctl so that processes can set their
floating-point exception mode on PPC and on PPC64. We need this
because the FP exception mode is controlled by bits in the machine
state register, which can only be accessed by the kernel, and because
the exception mode setting interacts with the lazy FPU save/restore
that the kernel does.

This is the patch to add support for PR_SET_FPEMU/PR_GET_FPEMU to give
per-process control over fp-emulation handling. It also cleans up the
way PR_SET_UNALIGN_CTL/PR_GET_UNALIGN_CTL are implemented.

- Dan Quinlan: cramfs update
- Ben Collins: IEEE 1394 update
- David Miller: network update (pppoe, routing cache stats), sparc32 update
- me: only dump core once per threaded app (first one wins)
- me: use new completion handlers for block device requests (same race
as with vfork, see -pre7)
