can: Network Drop Monitor: Make use of consume_skb() in af_can.c
Since commit
ead2ceb0ec9f85cff19c43b5cdb2f8a054484431 ("Network Drop
Monitor: Adding kfree_skb_clean for non-drops and modifying
end-of-line points for skbs") so called end-of-line points for skb's
should use consume_skb() to free the socket buffer.
In opposite to consume_skb() the function kfree_skb() is intended to
be used for unexpected skb drops e.g. in error conditions that now can
trigger the network drop monitor if enabled.
This patch moves the skb end-of-line point in af_can.c to use
consume_skb().

macb: process the RX ring regardless of interrupt status
Suppose that we receive lots of frames, start processing them, but
exhaust our budget so that we return before we had a chance to look
at all of them.
Then, when the network layer calls us again, we will only continue
processing the buffers if the REC bit was set in the mean time, which it
might not be if there was a brief pause in the flow of packets. If this
happens, we'll simply display a warning and call netif_rx_complete()
with potentially lots of unprocessed packets in the RX ring...
Fix this by scanning the ring no matter what flags are set in the
interrupt status register.

based on source and destination IP, which breaks when communicating
with sites having multiple addresses that require all connections to
originate from the same IP address.
Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the

skge_down() disables the TX queue, but then reenables it by mistake via
skge_tx_clean().
Fix it by moving the waking of the queue from skge_tx_clean() to the
other caller. And to make sure start_xmit is not in progress on another
CPU, skge_down() should call netif_tx_disable().

gro: Restore correct value to gso_size
Since everybody has been focusing on baremetal GRO performance
no one noticed when I added a bug that zapped gso_size for all

When I made the tun driver use non-linear packets as the preferred

a completely non-linear packet, which triggers a crash when we call

This patch reverts non-GSO users to using linear packets and adds

gro: Normalise skb before bypassing GRO on netpoll VLAN path
Hi:
gro: Normalise skb before bypassing GRO on netpoll VLAN path
When we detect netpoll RX on the GRO VLAN path we bail out and
call the normal VLAN receive handler. However, the packet needs
to be normalised by calling eth_type_trans since that's what the

tg3: Eliminate tg3_nvram_read_swab()
With the root cause being the use of memcpy to set the mac address:
memcpy(&dev->dev_addr[0], ((char *)&hi) + 2, 2);
memcpy(&dev->dev_addr[2], (char *)&lo, sizeof(lo));
This might work on little endian machines, but it can't on big endian

In addition, if the resume from hibernation is userland-driven, it's
better to wait for all device probes in the kernel to complete before

Fix a zero address hole bug in the bonding arp_ip_target list

Instead of just setting the array entry to zero, we now
copy any additional entries down one slot, putting the
zero entry at the end. With this change we can now have
all the loops that walk the array stop when they hit a zero
since there will be no addresses after it.

lockdep: continue lock debugging despite some taints
Impact: broaden lockdep checks
Lockdep is disabled after any kernel taints. This might be convenient
to ignore bad locking issues which sources come from outside the kernel
tree. Nevertheless, it might be a frustrating experience for the
staging developers or those who experience a warning but are focused
on another things that require lockdep.
The v2 of this patch simply don't disable anymore lockdep in case
of TAINT_CRAP and TAINT_WARN events.

lockdep: warn about lockdep disabling after kernel taint
Impact: provide useful missing info for developers
Kernel taint can occur in several situations such as warnings,
load of prorietary or staging modules, bad page, etc...
But when such taint happens, a developer might still be working on
the kernel, expecting that lockdep is still enabled. But a taint
disables lockdep without ever warning about it.
Such a kernel behaviour doesn't really help for kernel development.
This patch adds this missing warning.
Since the taint is done most of the time after the main message that
explain the real source issue, it seems safe to warn about it inside
add_taint() so that it appears at last, without hurting the main
information.
v2: Use a generic helper to disable lockdep instead of an
open coded xchg().

async: Fix module loading async-work regression
Several drivers use asynchronous work to do device discovery, and we
synchronize with them in the compiled-in case before we actually try to
mount root filesystems etc.
However, when compiled as modules, that synchronization is missing - the
module loading completes, but the driver hasn't actually finished
probing for devices, and that means that any user mode that expects to
use the devices after the 'insmod' is now potentially broken.
We already saw one case of a similar issue in the ACPI battery code,
where the kernel itself expected the module to be all done, and unmapped
the init memory - but the async device discovery was still running.
That got hacked around by just removing the "__init" (see commit
5d38258ec026921a7b266f4047ebeaa75db358e5 "ACPI battery: fix async boot
oops"), but the real fix is to just make the module loading wait for all
async work to be completed.
It will slow down module loading, but since common devices should be
built in anyway, and since the bug is really annoying and hard to handle
from user space (and caused several S3 resume regressions), the simple
fix to wait is the right one.
This fixes at least
http://bugzilla.kernel.org/show_bug.cgi?id=13063
but probably a few other bugzilla entries too (12936, for example), and
is confirmed to fix Rafael's storage driver breakage after resume bug
report (no bugzilla entry).
We should also be able to now revert that ACPI battery fix.
