7d69a1f4a7 remove CONFIG_UTS_NS and CONFIG_IPC_NS
CONFIG_UTS_NS and CONFIG_IPC_NS have very little value as they only
deactivate the unshare of the uts and ipc namespaces and do not improve
performance.

c7e12b8389 [PATCH] Fix ipc entries removal
Fix two issuses related to ipc_ids->entries freeing.

1. When freeing ipc namespace we need to free entries allocated
   with ipc_init_ids().

2. When removing old entries in grow_ary() ipc_rcu_putref()
   may be called on entries set to &ids->nullentry earlier in
   ipc_init_ids().
   This is almost impossible without namespaces, but with
   them this situation becomes possible.

Found during OpenVZ testing after obvious leaks in beancounters.

5f921ae96f [PATCH] sem2mutex: ipc, id.sem
Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

624dffcbcf correct email address of Manfred Spraul
I  tried to send the forcedeth maintainer an email, but it came back with:

"The mail address manfreds@colorfullife.com is not read anymore.
Please resent your mail to manfred@ instead of manfreds@."

This patch fixes this.

ae7817745e [PATCH] ipc: add generic struct ipc_ids seq_file iteration
The following two patches convert /proc/sysvipc/* to use seq_file.

This gives us the following:

 - Self-consistent IPC records in proc.
 - O(n) reading of the files themselves.

This patch:

Add a generic method for ipc types to be displayed using seq_file.  This
patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c

813e678364 [PATCH] xtensa: remove old syscalls
This patch fixes some minor bugs introduced by the previous patch (remove
old syscalls).  Both patches remove the obsolete syscalls.  The changes in
this patch were suggested by Arnd Bergmann.  The vmlinux.lds.S changes are
required for the latest gcc/binutils.

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!
