When BSD process accounting is enabled and logs information to a
filesystem which gets frozen, system easily becomes unusable because
each attempt to account process information blocks. Thus e.g. every task
gets blocked in exit.
It seems better to drop accounting information (which can already happen
when filesystem is running out of space) instead of locking system up.
So we just skip the write if the filesystem is frozen.

The IPC locking is a mess, and sem_unlock() unlocks not only the
semaphore spinlock, it also drops the rcu read lock. Unlike sem_lock(),
which just gets the spin-lock, and expects the caller to get the rcu
read lock.
This all makes things very hard to follow, and it's very confusing when
you take the rcu read lock in one function, and then release it in
another. And it has caused actual bugs: the sem_obtain_lock() function
ended up dropping the RCU read lock twice in one error path, because it
first did the sem_unlock(), and then did a rcu_read_unlock() to match
the rcu_read_lock() it had done.
This is just a totally mindless "remove rcu_read_unlock() from
sem_unlock() and add it immediately after each caller" (except for the
aforementioned bug where we did too many rcu_read_unlock(), and in
find_alloc_undo() where we just got the rcu_read_lock() to correct for
the fact that sem_unlock would immediately drop it again).
We can (and should) clean things up further, but this fixes the bug with
the minimal amount of subtlety.

Most LM75-compatible chips can either sample much faster or with a
much better resolution than the original LM75 chip. So far the lm75
driver did not let the user take benefit of these improvements. Do it
now.
I decided to almost always configure the chip to use the best
resolution possible, which also means the longest sample time. The
only chips for which I didn't are the DS75, DS1775 and STDS75, because
they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
so I went for 11-bit mode as a more reasonable tradeoff. This choice is
dictated by the fact that the hwmon subsystem is meant for system
monitoring, it has never been supposed to be ultra-fast, and as a
matter of fact we do cache the sampled values in almost all drivers.
If anyone isn't pleased with these default settings, they can always
introduce a platform data structure or DT support for the lm75. That
being said, it seems nobody ever complained that the driver wouldn't
refresh the value faster than every 1.5 second, and the change made
it faster for all chips even in 12-bit mode, so I don't expect any
complaint.

Prepare the lm75 driver to support per-chip resolution and sample

we still use the same, unchanged resolution (9-bit) and sample time

There is no standard for the configuration register bits of LM75-like
chips. We shouldn't blindly clear bits setting the resolution as they
are either unused or used for something else on some of the supported
chips.
So, switch to per-chip configuration initialization. This will allow
for better tuning later, for example using more resolution bits when
available.

The scheduler doesn't yet fully support environments
with a single task running without a periodic tick.
In order to ensure we still maintain the duties of scheduler_tick(),
keep at least 1 tick per second.
This makes sure that we keep the progression of various scheduler
accounting and background maintainance even with a very low granularity.
Examples include cpu load, sched average, CFS entity vruntime,
avenrun and events such as load balancing, amongst other details
handled in sched_class::task_tick().
This limitation will be removed in the future once we get
these individual items to work in full dynticks CPUs.

After recent 86a9bad3 (net: vlan: add protocol argument to packet
tagging functions) my sky2 started to crash on receive of tagged
frames, with backtrace similar to
#CRASH!!!
vlan_do_receive
__netif_receive_skb_core
__netif_receive_skb
netif_receive_skb
sky2_poll
...
__net_rx_action
__do_softirq
The problem turned out to be:
1) sky2 copies small packets from ring on RX, and in its
receive_copy() skb header is copied manually field, by field, and
only for some fields;
2) 86a9bad3 added skb->vlan_proto, which vlan_untag() or
__vlan_hwaccel_put_tag() set, and which is later used in
vlan_do_receive().
That patch updated copy_skb_header() for newly introduced
skb->vlan_proto, but overlooked the need to also copy it in sky2's
receive_copy().
Because of 2, we have the following scenario:
- frame is received and tagged in a ring, by sky2_rx_tag(). Both
skb->vlan_proto and skb->vlan_tci are set;
- later skb is decided to be copied, but skb->vlan_proto is
forgotten and becomes 0.
- in the beginning of vlan_do_receive() we call
__be16 vlan_proto = skb->vlan_proto;
vlan_dev = vlan_find_dev(skb->dev, vlan_proto, vlan_id);
which eventually invokes
vlan_proto_idx(vlan_proto)
and that routine BUGs for everything except ETH_P_8021Q and
ETH_P_8021AD.
Oops.
Fix it.
P.S.
Stephen, I wonder, why copy_skb_header() is not used in
sky2.c::receive_copy() ? Problems, where receive_copy was updated field
by field showed several times already, e.g.
3f42941b (sky2: propogate rx hash when packet is copied)
e072b3fa (sky2: fix receive length error in mixed non-VLAN/VLAN traffic)

Jakub reported that it is fairly easy to trigger the BUG() macro
from user space with TPACKET_V3's RX_RING by just giving a wrong
header status flag. We already had a similar situation in commit
7f5c3e3a80 (``af_packet: remove BUG statement in
tpacket_destruct_skb'') where this was the case in the TX_RING
side that could be triggered from user space. So really, don't use
BUG() or BUG_ON() unless there's really no way out, and i.e.
don't use it for consistency checking when there's user space
involved, no excuses, especially not if you're slapping the user
with WARN + dump_stack + BUG all at once. The two functions are
of concern:
prb_retire_current_block() [when block status != TP_STATUS_KERNEL]
prb_open_block() [when block_status != TP_STATUS_KERNEL]
Calls to prb_open_block() are guarded by ealier checks if block_status
is really TP_STATUS_KERNEL (racy!), but the first one BUG() is easily
triggable from user space. System behaves still stable after they are
removed. Also remove that yoda condition entirely, since it's already
guarded.

There is bug in the receive path of the asix driver at the time a

BUG: unable to handle kernel paging request at 0000004000000001
IP: [<ffffffff8126f65b>] skb_release_head_state+0x2d/0xd2

...
It is easily reproducable by setting an MTU of 512 e. g. and sending
something like
ping -s 1472 -c 1 -M do $SELF
from another box.
And this is because the rx->ax_skb is freed on error, but rx->ax_skb
is not reset, and the size is not reset to zero in this case.
And since the skb is added again to the usbnet->done skb queue it is
accessing already freed memory, resulting in the BUG when freeing a
2nd time. I therefore think the value 0x0000004000000001 show in the
trace is more or less random data.

When sending packets, TIPC bearers use skb_clone() before writing their
hardware header. This will however NOT copy the data buffer.
So when the same packet is sent over multiple bearers (to reach multiple
nodes), the same socket buffer data will be treated by multiple
tipc_media drivers which will write their own hardware header through
dev_hard_header().
Most of the time this is not a problem, because by the time the
packet is processed by the second media, it has already been sent over
the first one. However, when the first transmission is delayed (e.g.
because of insufficient bandwidth or through a shaper), the next bearer
will overwrite the hardware header, resulting in the packet being sent:
a) with the wrong source address, when bearers of the same type,
e.g. ethernet, are involved
b) with a completely corrupt header, or even dropped, when bearers of
different types are involved.
So when the same socket buffer is to be sent multiple times, send a
pskb_copy() instead (from the second instance on), and release it
afterwards (the bearer will skb_clone() it anyway).

- A new platform data parameter to specify ECC configuration;
- Rounding fixup to not waste memory in ecc_blocks;
- Restore ECC information printouts;
- A small code cleanup: use kmemdup where appropriate.

Simplify the memory detection code a bit by removing the CHUNK_OLDMEM
and CHUNK_CRASHK memory types.
They are not needed. Everything that is needed is a mechanism to
insert holes into the detected memory.

Add a notifier for kvm to get control before a page table entry is
invalidated. The notifier is only called for ptes of an address space
with pgstes that have been explicitly marked to require notification.
Kvm will use this to get control before prefix pages of virtual CPU
are unmapped.
