On commit 39c90ece7565f5c47110c2fa77409d7a9478bd5b:
[IPV4]: Convert rt_check_expire() from softirq processing to workqueue.
we converted rt_check_expire() from softirq to workqueue, allowing the
function to perform all work it was supposed to do.
When the IP route cache is big, rt_check_expire() can take a long time
to run. (default settings : 20% of the hash table is scanned at each
invocation)
Adding cond_resched() helps giving cpu to higher priority tasks if
necessary.
Using a "if (need_resched())" test before calling "cond_resched();" is
necessary to avoid spending too much time doing the resched check.
(My tests gave a time reduction from 88 ms to 25 ms per
rt_check_expire() run on my i686 test machine)

isdn_if.writebuf_skb has an additional ack flag argument which
was missing from sndpkt leading to the following warning:
CC [M] drivers/isdn/sc/init.o
drivers/isdn/sc/init.c: In function ‘sc_init’:

Note that this doesn't actually do anything with the flag, it
just fixes the warning (and probably accessing the last argument).

I broke this in commit 3de96471bd7fb76406e975ef6387abe3a0698149:
[TCP]: Wrap-safed reordering detection FRTO check
tcp_process_frto should always see a valid frto_highmark. An invalid
frto_highmark (zero) is very likely what ultimately caused a seqno
compare in tcp_frto_enter_loss to do the wrong leading to the LOST-bit
leak.
Having LOST-bits integry ensured like done after commit
23aeeec365dcf8bc87fae44c533e50d0bb4f23cc:
[TCP] FRTO: Plug potential LOST-bit leak

Commit fcc5a03ac42564e9e255c1134dda47442289e466:
[NET]: Allow netdev REGISTER/CHANGENAME events to fail
makes the register_netdevice_notifier() handle the error from the
NETDEV_REGISTER event, sent to the registering block.
The bad news is that in this case the notifier block is
not removed from the list, but the error is returned to the
caller. In case the caller is in module init function and
handles this error this can abort the module loading. The
notifier block will be then removed from the kernel, but
will be left in the list. Oops :(
I think that the notifier block should be removed from the
chain in case of error, regardless whether this error is
handled by the caller or not. In the worst case (the error
is _not_ handled) module will not receive the events any
longer.

If fs_enet is build as module, on PPC_CPM_NEW_BINDING platforms
mii-fec/mii-bitbang should be build as module, as well. On other
platforms, mii-fec/mii-bitbang must be included into the main module.
Otherwise some symbols remain undefined. Additionally, fs_enet uses
libphy, so add a select PHYLIB.

NULL ptr can be returned from tcp_write_queue_head to cached_skb
and then assigned to skb if packets_out was zero. Without this,
system is vulnerable to a carefully crafted ACKs which obviously
is remotely triggerable.
Besides, there's very little that needs to be done in sacktag
if there weren't any packets outstanding, just skipping the rest
doesn't hurt.

We round up the header size in sk_stream_alloc_pskb so that
TSO packets get zero tail room. Unfortunately this rounding
up is not coordinated with the select_size() function used by
TCP to calculate the second parameter of sk_stream_alloc_pskb.
As a result, we may allocate more than a page of data in the
non-TSO case when exactly one page is desired.
In fact, rounding up the head room is detrimental in the non-TSO
case because it makes memory that would otherwise be available to
the payload head room. TSO doesn't need this either, all it wants
is the guarantee that there is no tail room.
So this patch fixes this by adjusting the skb_reserve call so that
exactly the requested amount (which all callers have calculated in
a precise way) is made available as tail room.

All 32 bits machines but i386 dont have CONFIG_KTIME_SCALAR. On these
machines, ktime.tv64 is more than 4 times the (correct) result given
by ktime_to_ns()
Again on these machines, using ktime_get_real().tv64 >> 6 give a
32bits rollover every 64 seconds, which is not wanted (less than the
120 s MSL)
Using ktime_to_ns() is the portable way to get nsecs from a ktime, and
have correct code.

It might be possible that, in some extreme scenario that
I just cannot now construct in my mind, end_seq <=
frto_highmark check does not match causing the lost_out
and LOST bits become out-of-sync due to clearing and
recounting in the loop.
This may fix LOST-bit leak reported by Chazarain Guillaume

Otherwise TCP might violate packet ordering principles that FRTO
is based on. If conventional recovery path is chosen, this won't
be significant at all. In practice, any small enough value will
be sufficient to provide proper operation for FRTO, yet other
users of snd_cwnd might benefit from a "close enough" value.
FRTO's formula is now equal to what tcp_enter_cwr() uses.
FRTO used to check application limitedness a bit differently but
I changed that in commit 575ee7140dabe9b9c4f66f4f867039b97e548867
and as a result checking for application limitedness became
completely non-existing.

The only qdiscs that check subqueue state before dequeue'ing are PRIO
and RR. The other qdiscs, including the default pfifo_fast qdisc,
will allow traffic bound for subqueue 0 through to hard_start_xmit.
The check for netif_queue_stopped() is done above in pkt_sched.h, so
it is unnecessary for qdisc_restart(). However, if the underlying
driver is multiqueue capable, and only sets queue states on subqueues,
this will allow packets to enter the driver when it's currently unable
to process packets, resulting in expensive requeues and driver
entries. This patch re-adds the check for the subqueue status before
calling hard_start_xmit, so we can try and avoid the driver entry when
the queues are stopped.

Scrap the local __INLINE__ macro, and rename timeval_cmp to fasttime_cmp.
Inline macro was completely unnecessary since the macro was defined

timeval_cmp was inaccurately named since it does comparison on

- Keep interrupts disabled as long as we have a reference to the
fasttimer list and only enable them while doing the callback.
del_fast_timer may be called from other interrupt context.
- Fix bug where debug code could return without calling local_irq_restore.
- Use jiffies instead of usec (change from struct timeval to fasttime_t).
- Don't initialize static variables to zero.
- Remove obsolete #ifndef DECLARE_WAITQUEUE code.
- fast_timer_init should be __initcall.
- Change status/debug variables to unsigned.

New and improved serial driver for CRISv10, take three, with improvements
suggested by Jiri Slaby.
- Call wait_event_interruptible with a _correct_ and sensible condition.
- Removed superfluous test of info->flags & ASYNC_CLOSING, since that is done
by wait_event_interruptible.
- Moved common code for deregistering DMA and IRQ to deinit_port function.
- Use setup_timer when initializing flush_timer.
- Convert bit-field for uses_dma_in and uses_dma_out to regular bytes.
- Removed CVS tags.
- Removed defines and comments for CRIS_BUF_SIZE and TTY_THRESHOLD_THROTTLE
(no longer used).
- Cleaned up code to pass checkpatch.
- Add crisv10.h header file.
- Merge of CRISv10 from Axis internal CVS.

Corrects compile errors and the following:
- Remove oldset parameter from do_signal and do_notify_resume.
- Modified to fit new consolidated IRQ handling code.
- Reverse check order between external nmi and watchdog nmi to avoid false
watchdog oops in case of a glitch on the nmi pin.
- Return from an pin-generated NMI the same way as for other interrupts.
- Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
low-level asm interrupt handlers. Fixed in the multiple interrupt
handler also.
- Add space for thread local storage in thread_info struct.
- Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
rtc and pci.

New (updated) version of ethernet driver for cris v10.
- First steps to simplify and make the MII code more similar
between the etrax100 and etraxfs ports.
- Start the transmit queue before enabling tx interrupts
to avoid race with the first frame.
- Flip the comparition statement to stick to physical addresses
to avoid phys_to_virt mapping a potential null pointer.
This was not an error but the change simplifies debugging
of address-space mappings.
- Made myPrevRxDesc local to e100_rx since it was only used there.
Fixed out of memory handling in e100_rx. If dev_alloc_skb() fails
persistently the system is hosed anyway but at least it won't
loop in an interrupt handler.
- Correct some code formatting issues.
- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

Fix regression introduced with d435d862baca3e25e5eec236762a43251b1e7ffc
("cpu hotplug: mce: fix cpu hotplug error handling").
A CPU which was not brought up during boot (using maxcpus and
additional_cpus parameters) couldn't be onlined anymore. For such a CPU it
seemed that MCE was not supported during CPU_UP_PREPARE-time which caused
mce_cpu_callback to return NOTIFY_BAD to notifier_call_chain. To fix this
we:
- call mce_create_device for CPU_ONLINE event (instead of CPU_UP_PREPARE),
- avoid mce_remove_device() for the CPU that is not correctly initialized
by mce_create_device() failure,
- make mce_cpu_callback always return NOTIFY_OK for CPU_ONLINE event.
Because CPU_ONLINE callback return value is always ignored.
