commit b1c4a9dddf09fe99b8f88252718ac5b357363dc4 ("ucc_geth: Change
uec phy id to the same format as gianfar's") introduced a regression
in the ucc_geth driver that causes this oops when fixed-link is used:
Unable to handle kernel paging request for data at address 0x00000000
Faulting instruction address: 0xc0151270
Oops: Kernel access of bad area, sig: 11 [#1]

This patch fixes the issue by removing offending (and somewhat
duplicate) code from init_phy() routine, and changes _probe()
function to use uec_mdio_bus_name().
Also, since we fully construct phy_bus_id in the _probe() routine,
we no longer need ->phy_address and ->mdio_bus fields in
ucc_geth_info structure.
I wish the patch would be a bit shorter, but it seems like the only
way to fix the issue in a sane way. Luckily, the patch has been
tested with real PHYs and fixed-link, so no further regressions
expected.

This fixes a locking bug in the dm9000 driver. It calls
request_irq() without setting IRQF_DISABLED ... which is
correct for handlers that support IRQ sharing, since that
behavior is not guaranteed for shared IRQs. However, its
IRQ handler then wrongly assumes that IRQs are blocked.
So the fix just uses the right spinlock primitives in the
IRQ handler.
NOTE: this is a classic example of the type of bug which
lockdep currently masks by forcibly setting IRQF_DISABLED
on IRQ handlers that did not request that flag.

NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS handlers
did not verify whether a function pointer is NULL (not supported by
the driver) before trying to call the function. The former nl80211
command is available for unprivileged users, too, so this can
potentially allow normal users to kill networking (or worse..) if
mac80211 is built without CONFIG_MAC80211_MESH=y.

smsc911x_phy_adjust_link is called periodically by the phy layer (as
it's run in polling mode), and it only updates the hardware when it sees
a change in duplex or carrier. This patch clears the last known values
every time the interface is brought up, instead of only when the module
is loaded.
Without this patch the adjust_link function never updates the hardware
after an ifconfig down; ifconfig up. On a full duplex link this causes
the tx error counter to increment, even though packets are correctly
transmitted, as the default MAC_CR register setting is for half duplex.
The tx errors are "no carrier" errors, which should be ignored in
full-duplex mode. When MAC_CR is set to "full duplex" mode they are
correctly ignored by the hardware.
Note that even with this patch the tx error counter can increment if
packets are transmitted between "ifconfig up" and the first phy poll
interval. An improved solution would use the phy interrupt with phylib,
but I haven't managed to make this work 100% robustly yet.

dev can be NULL in ip[6]_frag_reasm for skb's coming from RAW sockets.
Quagga's OSPFD sends fragmented packets on a RAW socket, when netfilter
conntrack reassembles them on the OUTPUT path you hit this code path.
You can test it with something like "hping2 -0 -d 2000 -f AA.BB.CC.DD"

Tulip is currently doing request_irq before it has done its
initialization. This is usually not a problem because it hasn't
enable interrupts yet, but with DEBUG_SHIRQ on, we call the irq handler
when registering the interrupt as a sanity check.
This can result in a NULL ptr dereference, so call tulip_init_ring
before request_irq, and add a free_ring function to do the freeing
now shared with tulip_close.
Tested with a shell loop running ifup, ifdown in a loop a few hundred
times with DEBUG_SHIRQ on.

Impact: Make NetworkManager work with virtio_net
For now the semantics are simple: There is always carrier.
This allows a seamless experience with e.g., qemu/kvm
where NetworkManager just configures and sets up
everything automagically.
If/when a generally agreed-upon way to control
carrier on/off in the emulator/hypervisor level
emerges, it will be trivial to extend the driver
to support that too, but for now even this 2-liner
makes user experience that much better.

bonding: refactor mii monitor
The un-refactored code checked the link speed and duplex of
every slave on every pass; the refactored code did not do so.
The 802.3ad and balance-alb/tlb modes utilize the speed and
duplex information, and require it to be kept up to date. This patch
adds a notifier check to perform the appropriate updating when the slave
device speed changes.

The MSI-X handler was chosen before the call to pci_enable_msix().
If MSI-X was not available, the wrong MSI-X handler would be used in
INTA mode. This would cause a screaming interrupt problem because
INTA would not be cleared by the MSI-X handler.
Fixed by assigning MSI-X handler after pci_enable_msix() returns
successfully. Also update version to 1.9.3.

zd_op_tx() must not return an arbitrary error value since that can
leave mac80211 trying to retransmit the frame and with the extra data
pushed into the beginning of the skb on every attempt, this will end up
causing a kernel panic (skb_under_panic from skb_push call). This can
happen, e.g., when ejecting the device when associated.

It was possible to hit a kernel panic on NULL pointer dereference in
dev_queue_xmit() when sending power save buffered frames to a STA that
woke up from sleep. This happened when the buffered frame was requeued
for transmission in ap_sta_ps_end(). In order to avoid the panic, copy
the skb->dev and skb->iif values from the first fragment to all other
fragments.

On the legacy netif_rx path, I incorrectly tried to optimise
the napi_complete call by using __napi_complete before we reenable
IRQs. This simply doesn't work since we need to flush the held

This patch fixes it by doing the obvious thing of reenabling
IRQs first and then calling napi_complete.

When you compile kernel on Sparc64 with heap memory checking and type
"cat /proc/iomem", you get a crash, because pointers in struct
resource are uninitialized.
Most code fills struct resource with zeros, so I assume that it is
responsibility of the caller of request_resource to initialized it,
not the responsibility of request_resource functuion.
After 2.6.29 is out, there could be a check for uninitialized fields
added to request_resource to avoid crashes like this.

This patch fixes bug #12208:
Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208
Subject : uml is very slow on 2.6.28 host
This turned out to be not a scheduler regression, but an already
existing problem in ptrace being triggered by subtle scheduler
changes.
The problem is this:
- task A is ptracing task B
- task B stops on a trace event
- task A is woken up and preempts task B
- task A calls ptrace on task B, which does ptrace_check_attach()
- this calls wait_task_inactive(), which sees that task B is still on the runq
- task A goes to sleep for a jiffy
- ...
Since UML does lots of the above sequences, those jiffies quickly add
up to make it slow as hell.
This patch solves this by not rescheduling in read_unlock() after
ptrace_stop() has woken up the tracer.
Thanks to Oleg Nesterov and Ingo Molnar for the feedback.

Grant picked up the wrong version of "Respect _PAGE_COHERENT on classic
ppc32 SW" (commit a4bd6a93c3f14691c8a29e53eb04dc734b27f0db)
It was missing the code to actually deal with the fixup of
_PAGE_COHERENT based on the CPU feature.

'make randconfig' uses glibc's rand function, and the seed of
that PRNG is set via:
srand(time(NULL));
But 'time()' only increases once every second - freezing the
randconfig result within a single second.
My Nehalem testbox does randconfig much faster than 1 second
and i have a few scripts that do 'randconfig until condition X'
loops.
Those scripts currently waste a lot of CPU time due to randconfig
changing its seed only once per second currently.
Change the seed to be micrseconds based. (I checked the statistical
spread of the seed - the now.tv_sec*now.tv_usec multiplication
there further improves it.)

Ingo Molnar reported that 'make randconfig' was not covering
choice blocks properly, resulting in certain config options
being left out of randconfig testing altogether.
With the following patch we:
- properly randomize choice value for normal choice blocks
- properly randomize for multi choice blocks
- added several comments to explain what is going on
The root cause of the bug was that SYMBOL_VALID was set on the
symbol representing the choice block so clearing this did
the trick initially.
But testign revealed a few more issues that is now fixed.

It is trivial to merge the non-MMU and MMU versions of siginfo.h.
Without a single file "make headers_install" is broken for m68k
(since each of the sub-varients of siginfo.h are not installed).

The MMU version of unistd.h can be use on non-MMU platrorms as well.
