* remove asm/atomic.h inclusion from linux/utsname.h --
not needed after kref conversion
* remove linux/utsname.h inclusion from files which do not need itNOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.Signed-off-by: Alexey Dobriyan

The members of the new_utsname structure are defined with magic numbers
that *should* correspond to the constant __NEW_UTS_LEN+1. Everywhere
else, code assumes this and uses the constant, so this patch makes the
structure match.Originally suggested by Serge here:

Currently all the namespace management code is in the kernel/utsname.c file,
so just compile it out and make stubs in the appropriate header.The init namespace itself is in init/version.c and is in the kernel all the
time.Signed-off-by: Pavel Emelyanov

While working on unshare support for the network namespace I noticed we
were putting clone flags in an int. Which is weird because the syscall
uses unsigned long and we at least need an unsigned to properly hold all of
the unshare flags.So to make the code consistent, this patch updates the code to use
unsigned long instead of int for the clone flags in those places
where we get it wrong today.Signed-off-by: Eric W. Biederman

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.Signed-off-by: Cedric Le Goater

sys_clone() and sys_unshare() both makes copies of nsproxy and its associated
namespaces. But they have different code paths.This patch merges all the nsproxy and its associated namespace copy/clone
handling (as much as possible). Posted on container list earlier for
feedback.- Create a new nsproxy and its associated namespaces and pass it back to
caller to attach it to right process.- Changed all copy_*_ns() routines to return a new copy of namespace
instead of attaching it to task->nsproxy.- Moved the CAP_SYS_ADMIN checks out of copy_*_ns() routines.
- Removed unnessary !ns checks from copy_*_ns() and added BUG_ON()
just incase.- Get rid of all individual unshare_*_ns() routines and make use of
copy_*_ns() instead.[akpm@osdl.org: cleanups, warning fix]

When CONFIG_UTS_NS=n, clone(CLONE_NEWUTS) quietly refuses. So correctly does
not unshare a new uts namespace, but also does not return -EINVAL.Fix this to return -EINVAL so the caller knows his request was denied.

This patch defines the uts namespace and some manipulators.
Adds the uts namespace to task_struct, and initializes a
system-wide init namespace.It leaves a #define for system_utsname so sysctl will compile.
This define will be removed in a separate patch.[akpm@osdl.org: build fix, cleanup]

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!
