If CONFIG_NET_NS is not set, the only namespace is possible.
This patch removes list of pernet_operations and cleanups code a bit.
This list is not needed if there are no namespaces. We should just call
->init method.
Additionally, the ->exit will be called on module unloading only. This
case is safe - the code is not discarded. For the in/kernel code, ->exit
should never be called.

Previous devices hardcoded the PCI Maximum Read Request Size to 4K. To
better comply with the PCI spec, the hardware now defaults the MRRS to
512 bytes. This will yield poor driver performance if left untouched.

5784 and 5764 devices fail to link / pass traffic after one load /
unload cycle. This happens because of a hardware bug in the new CPMU.
During normal operation, the MAC depends on the PHY clock being
available. When the PHY is powered down, the clock the MAC depends on
is disabled. The fix is to switch the MAC clock to an alternate source
before powering down the PHY, and to restore the MAC clock to the PHY
source upon device resume.

When 5761 devices boot the machine using PXEboot, PXE leaves the device
active when it terminates. The tg3 driver has code to detect this
condition and resets the device during initialization. On 5761 devices,
device resets involve sending a driver state update message to the APE
on the 5761. However, during this initialization stage, communications
to the APE registers have not yet been set up. The driver then
dereferences a NULL pointer and crashes the machine. The fix is to move
the APE register access setup earlier in the initialization code to
cover this condition.

...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers.
Looking at the sock->op->shutdown() handlers, it looks as if all of them

Commit bea3348e (the NAPI changes) made sungem unconditionally enable
NAPI when resuming and unconditionally disable when suspending, this,
however, makes napi_disable() hang when suspending when the interface
was taken down before suspend because taking the interface down also
disables NAPI. This patch makes touching the napi struct in
suspend/resume code paths depend on having the interface up, thereby
fixing the hang on suspend.
The patch also moves the napi_disable() in gem_close() under the lock so
that the NAPI state is always modified atomically together with the
"opened" variable.

While a signal is blocked, it must be posted even if its action is
SIG_IGN or is SIG_DFL with the default action to ignore. This works
right most of the time, but is broken when a sigwait (rt_sigtimedwait)
is in progress. This changes the early-discard check to respect
real_blocked. ~blocked is the set to check for "should wake up now",
but ~(blocked|real_blocked) is the set for "blocked" semantics as
defined by POSIX.

As with commit 7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1 ("knfsd: nfsd:
call nfsd_setuser() on fh_compose(), fix nfsd4 permissions problem")
this is a case where we need to redo a security check in fh_verify()
even though the filehandle already has an associated dentry--if the
filehandle was created by fh_compose() in an earlier operation of the
nfsv4 compound, then we may not have done these checks yet.
Without this fix it is possible, for example, to traverse from an export
without the secure ports requirement to one with it in a single
compound, and bypass the secure port check on the new export.
While we're here, fix up some minor style problems and change a printk()
to a dprintk(), to make it harder for random unprivileged users to spam
the logs.

The v2/v3 acl code in nfsd is translating any return from fh_verify() to
nfserr_inval. This is particularly unfortunate in the case of an
nfserr_dropit return, which is an internal error meant to indicate to
callers that this request has been deferred and should just be dropped
pending the results of an upcall to mountd.

The coredump code always calls set_dumpable(0) when it starts (even
if RLIMIT_CORE prevents any core from being dumped). The effect of
this (via task_dumpable) is to make /proc/pid/* files owned by root
instead of the user, so the user can no longer examine his own
process--in a case where there was never any privileged data to
protect. This affects e.g. auxv, environ, fd; in Fedora (execshield)
kernels, also maps. In practice, you can only notice this when a
debugger has requested PTRACE_EVENT_EXIT tracing.
set_dumpable was only used in do_coredump for synchronization and not
intended for any security purpose. (It doesn't secure anything that wasn't
already unsecured when a process dies by SIGTERM instead of SIGQUIT.)
This changes do_coredump to check the core_waiters count as the means of
synchronization, which is sufficient. Now we leave the "dumpable" bits alone.

In net/sctp/sm_statefuns.c::sctp_sf_abort_violation() we may leak
the storage allocated for 'abort' by returning from the function
without using or freeing it. This happens in case
"sctp_auth_recv_cid(SCTP_CID_ABORT, asoc)" is true and we jump to
the 'discard' label.
Spotted by the Coverity checker.
The simple fix is to simply move the creation of the "abort chunk"
to after the possible jump to the 'discard' label. This way we don't
even have to allocate the memory at all in the problem case.

The virtio descriptor rings of size N-1 were nicely set up to be
aligned to an N-byte boundary. But as Anthony Liguori points out, the
free-running indices used by virtio require that the sizes be a power
of 2, otherwise we get problems on wrap (demonstrated with lguest).
So we replace the clever "2^n-1" scheme with a simple "align to page
boundary" scheme: this means that all virtio rings take at least two
pages, but it's safer than guessing cache alignment.

The more_used() function compares the vq->vring.used->idx with last_used_idx.
Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an

wraps around.
This patch corrects this by changing last_used_idx to the correct type.

The unix_nr_socks value is limited with the 2 * get_max_files() value,
as seen from the unix_create1(). However, the check and the actual
increment are separated with the GFP_KERNEL allocation, so this limit
can be exceeded under a memory pressure - task may go to sleep freeing
the pages and some other task will be allowed to allocate a new sock
and so on and so forth.
So make the increment before the check (similar thing is done in the
