net: introduce netdev_alloc_frag()
Fix two issues introduced in commit
a1c7fff7e18f5
( net: netdev_alloc_skb() use build_skb() )
- Must be IRQ safe (non NAPI drivers can use it)
- Must not leak the frag if build_skb() fails to allocate sk_buff
This patch introduces netdev_alloc_frag() for drivers willing to
use build_skb() instead of __netdev_alloc_skb() variants.
Factorize code so that :
__dev_alloc_skb() is a wrapper around __netdev_alloc_skb(), and
dev_alloc_skb() a wrapper around netdev_alloc_skb()
Use __GFP_COLD flag.
Almost all network drivers now benefit from skb->head_frag
infrastructure.

iwlwifi: dont pull too much payload in skb head
As iwlwifi use fat skbs, it should not pull too much data in skb->head,
and particularly no tcp data payload, or splice() is slower, and TCP
coalescing is disabled. Copying payload to userland also involves at
least two copies (part from header, part from fragment)
Each layer will pull its header from the fragment as needed.
(on 64bit arches, skb_tailroom(skb) at this point is 192 bytes)
With this patch applied, I have a major reduction of collapsed/pruned
TCP packets, a nice increase of TCPRcvCoalesce counter, and overall
better Internet User experience.
Small packets are still using a fragless skb, so that page can be reused
by the driver.

Queue selection is done as follows:
If the mqprio qdisc is operates on the interface, such that the core networking

Else, the egress map skb->priority => User priority is used for tagged traffic, and

arch/tile: fix up some issues in calling do_work_pending()
First, we were at risk of handling thread-info flags, in particular
do_signal(), when returning from kernel space. This could happen
after a failed kernel_execve(), or when forking a kernel thread.
The fix is to test in do_work_pending() for user_mode() and return
immediately if so; we already had this test for one of the flags,
so I just hoisted it to the top of the function.
Second, if a ptraced process updated the callee-saved registers
in the ptregs struct and then processed another thread-info flag, we
would overwrite the modifications with the original callee-saved
registers. To fix this, we add a register to note if we've already
saved the registers once, and skip doing it on additional passes
through the loop. To avoid a performance hit from the couple of
extra instructions involved, I modified the GET_THREAD_INFO() macro
to be guaranteed to be one instruction, then bundled it with adjacent
instructions, yielding an overall net savings.

"The device_connected fix should be quite self-explanatory, but it's

As for the security level patch, this fixes L2CAP socket based security

net/mlx4_core: Change SYNC_TPT to be native (not wrapped)
The "wrapped" was incorrect, since no wrapper function was defined.

net/mlx4_core: Fix init_port mask state for slaves
In function mlx4_INIT_PORT_wrapper, the port state mask for the
slave is only set if we are invoking the INIT_PORT fw command.
However, the reference count for the (initialized) port is
incremented anyway.
This creates a problem in that when we have multiple slaves,
then the CLOSE_PORT command will never be invoked. The
reason is that in the CLOSE_PORT wrapper, if the port-state
mask is zero for the slave (which it is), the wrapper returns
without doing anything. The only slave which will not return
immediately in the CLOSE_PORT wrapper is that slave for which
INIT_PORT was invoked.
The fix is to not have the port-state mask setting depend
on the logic for calling the INIT_PORT fw command.

tokenring: delete all remaining driver support
This represents the mass deletion of the of the tokenring support.
It gets rid of:
- the net/tr.c which the drivers depended on
- the drivers/net component
- the Kbuild infrastructure around it
- any tokenring related CONFIG_ settings in any defconfigs
- the tokenring headers in the include/linux dir
- the firmware associated with the tokenring drivers.
- any associated token ring documentation.

net: delete all instances of special processing for token ring
We are going to delete the Token ring support. This removes any
special processing in the core networking for token ring, (aside
from net/tr.c itself), leaving the drivers and remaining tokenring
support present but inert.
The mass removal of the drivers and net/tr.c will be in a separate
commit, so that the history of these files that we still care
about won't have the giant deletion tied into their history.
