bnx2: fix poll_controller to pass proper structures and check all rx queues
Fix bnx2 so that netpoll works properly. Specifically:
1) Fix parameters to bnx2_interrupt to be a struct bnx2_napi rather than a
struct net_device
2) Fix poll_controller method to check every queue in the rx case so frames
aren't missed

niu: Fix readq implementation when architecture does not provide one.
This fixes a TX hang reported by Jesper Dangaard Brouer.
When an architecutre cannot provide a fully functional
64-bit atomic readq/writeq, the driver must implement
it's own. This is because only the driver can say whether
doing something like using two 32-bit reads to implement
the full 64-bit read will actually work properly.
In particular one of the issues is whether the top 32-bits
or the bottom 32-bits of the 64-bit register should be read
first. There could be side effects, and in fact that is
exactly the problem here.
The TX_CS register has counters in the upper 32-bits and
state bits in the lower 32-bits. A read clears the state
bits.
We would read the counter half before the state bit half.
That first read would clear the state bits, and then the
driver thinks that no interrupts are pending because the
interrupt indication state bits are seen clear every time.
Fix this by reading the bottom half before the upper half.

hostap: pad the skb->cb usage in lieu of a proper fix
Like mac80211 did, this driver makes 'clever' use of skb->cb to pass
information along with an skb as it is requeued from the virtual device
to the physical wireless device. Unfortunately, that trick no longer
works...
Unlike mac80211, code complexity and driver apathy makes this hack
the best option we have in the short run. Hopefully someone will
eventually be motivated to code a proper fix before all the effected
hardware dies.

V4L/DVB (9492): unplug oops from dvb_frontend_init...
When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with
2.6.24, I was met with an oops [1]. The problem is relevant to
2.6.25/26-rc also.
dvb_frontend_init() was called either from re-creation of the kdvb-fe0
thread - seems unlikely, or someone called
dvb_frontend_reinitialise(), causing this path in the thread - really
unlikely, as I can't find any call-site for it.
Either way, quite a number of drivers call dvb_usb_generic_rw() [2]
without checking the validity of the relevant member in the
dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw()
sanity-check and fail (rather than loading from 0x120) seems
reasonable defensive programming [3], in light of it being called in
this way.
The problem with this, is that drivers don't check the return code of
the init call [4]. Does it make sense to cook a patch which allows the
failure to be propagated back up, or am I missing something else?
Thanks,
Daniel

V4L/DVB (9357): cx88-dvb: Fix Oops in case i2c bus failed to register
There already is an report at kernel bugzilla about this issue:
http://bugzilla.kernel.org/show_bug.cgi?id=9455
When enabling extra checks for the i2c-bus of cx88 based cards by
loading i2c_algo_bit with bit_test=1 this may trigger an oops
when loading cx88_dvb.
This is caused by the extra check code that detects that the
sda-line is stuck high and thus does not register the i2c-bus.
cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

V4L/DVB (9356): [PATCH] saa7134: fix resource map sanity check conflict
Impact: driver could possibly stomp on resources outside of its scope
{mchehab@redhat.com: I got two versions of the same patch (identical,
except for whitespacing). One authored by Andy Burns and another
authored by Suresh Siddha. Due to that, I'm applying the one that has
less CodingStyle errors. I'm also adding both comments and the SOB's for
both patches, since they are both interesting}
Suresh Siddha commented:
Alexey Fisher reported:
> resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000
> 0xcfefffff PCI Bus 0000:01
BAR base is located in the middle of the 4K page and the hardcoded
size argument makes the request span two pages causing the conflict.
Fix the hard coded size argument in ioremap().
Andy Burns commented:
I have already sent this patch on the linux-dvb list, but it didn't get
much attention, so re-sending direct, I hope you all don't mind.
While attempting to run mythtv in a xen domU, I encountered problems
loading the driver for my saa7134 card, with an error from ioremap().
This error was due to the driver allocating an incorrectly sized mmio
area, which was trapped by xen's permission checks, but this would go
un-noticed on a kernel without xen.
My card has a 1K sized mmio area, I've had information that other cards
have 2K areas, perhaps others have different sizes, yet the driver
always attempts to map 4K. I realise that the granularity of mapping is
the page size, which typically would be 4K, but unless the card's base
address happens to fall on a 4K boundary (mine does not) then the
base+4K will end up spanning two pages, and this is when the error
occurs under xen.
My patch uses the pci_resource_len macro to determine the size required
for the user's particular card, instead of the hardcoded 4K value. I've
tested with a couple of printk() inside ioremap() that the start address
and size do get rounded to the closest page boundary.
With this patch I am able to successfully load the saa7134 driver and
run mythtv under xen with my card, subject to correct pollirq settings
in case of shared IRQ, I am still seeing occasional DMA panics, which I
think are related to swiotlb handling by dom0/domU, usually the panic
occurs when changing mux, once tuned to a mux, 12 hour continuous
recordings are possible without errors.

timers: handle HRTIMER_CB_IRQSAFE_UNLOCKED correctly from softirq context
Impact: fix incorrect locking triggered during hotplug-intense stress-tests
While migrating the the CB_IRQSAFE_UNLOCKED timers during a cpu-offline,
we queue them on the cb_pending list, so that they won't go
stale.
Thus, when the callbacks of the timers run from the softirq context,
they could run into potential deadlocks, since these callbacks
assume that they're running with irq's disabled, thereby annoying
lockdep!
Fix this by emulating hardirq context while running these callbacks from
the hrtimer softirq.

RDMA/cxgb3: deadlock in iw_cxgb3 can cause hang when configuring interface.
When the iw_cxgb3 module's cxgb3_client "add" func gets called by the
cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo
function in cxgb3 to get the fw version and other info. Currently the
iwarp driver grabs the rtnl lock around this down call to serialize.
As of 2.6.27 or so, things changed such that the rtnl lock is held around
the call to the netdev driver open function. Also the cxgb3_client "add"
function doesn't get called if the device is down.
So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device,
the iw_cxgb3 add func gets called with the rtnl_lock held. If you
load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func
gets called without the rtnl_lock held. The former causes the deadlock,
the latter does not.
In addition, there are iw_cxgb3 sysfs handlers that also can call
down into cxgb3 to gather the fw and hw versions. These can be called
concurrently on different processors and at any time. Thus we need to
push this serialization down in the cxgb3 driver get_drvinfo func.
The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

ring-buffer: prevent infinite looping on time stamping
Impact: removal of unnecessary looping
The lockless part of the ring buffer allows for reentry into the code
from interrupts. A timestamp is taken, a test is preformed and if it
detects that an interrupt occurred that did tracing, it tries again.
The problem arises if the timestamp code itself causes a trace.
The detection will detect this and loop again. The difference between
this and an interrupt doing tracing, is that this will fail every time,
and cause an infinite loop.
Currently, we test if the loop happens 1000 times, and if so, it will
produce a warning and disable the ring buffer.
The problem with this approach is that it makes it difficult to perform
some types of tracing (tracing the timestamp code itself).
Each trace entry has a delta timestamp from the previous entry.
If a trace entry is reserved but and interrupt occurs and traces before
the previous entry is commited, the delta timestamp for that entry will
be zero. This actually makes sense in terms of tracing, because the
interrupt entry happened before the preempted entry was commited, so
one may consider the two happening at the same time. The order is
still preserved in the buffer.
With this idea, instead of trying to get a new timestamp if an interrupt
made it in between the timestamp and the test, the entry could simply
make the delta zero and continue. This will prevent interrupts or
tracers in the timer code from causing the above loop.

netfilter: payload_len is be16, add size of struct rather than size of pointer
payload_len is a be16 value, not cpu_endian, also the size of a ponter
to a struct ipv6hdr was being added, not the size of the struct itself.

ipv6: fix ip6_mr_init error path
The order of cleanup operations in the error/exit section of ip6_mr_init()
is completely inversed. It should be the other way around.
Also a del_timer() is missing in the error path.

[2/4] I/OAT: fix dma_pin_iovec_pages() error handling
Error handling needs to be modified in dma_pin_iovec_pages().
It should return NULL instead of ERR_PTR
(pinned_list is checked for NULL in tcp_recvmsg() to determine
if iovec pages have been successfully pinned down).
In case of error for the first iovec,
local_list->nr_iovecs needs to be initialized.

nohz: disable tick_nohz_kick_tick() for now
Impact: nohz powersavings and wakeup regression
commit
fb02fbc14d17837b4b7b02dbb36142c16a7bf208 (NOHZ: restart tick
device from irq_enter()) causes a serious wakeup regression.
While the patch is correct it does not take into account that spurious
wakeups happen on x86. A fix for this issue is available, but we just
revert to the .27 behaviour and let long running softirqs screw
themself.
Disable it for now.
