When emulating an instruction that reads the destination memory operand (i.e.,
instructions without the Mov flag in the emulator), the operand is first read.
If a page-fault is detected in this phase, the error-code which would be
delivered to the VM does not indicate that the access that caused the exception
is a write one. This does not conform with real hardware, and may cause the VM
to enter the page-fault handler twice for no reason (once for read, once for
write).

When software changes D bit (either from 1 to 0, or 0 to 1), the
corresponding TLB entity in the hardware won't be updated immediately. We
should flush it to guarantee the consistence of D bit between TLB and
MMU page table in memory. This is especially important when clearing
the D bit, since it may cause false negatives in reporting dirtiness.

====================
Involve rhashtable_lookup_insert routine
The series aims to involve rhashtable_lookup_insert() to guarantee
that the process of lookup and insertion of an object from/into hash
table is finished atomically, allowing rhashtable's users not to
introduce an extra lock during search and insertion. For example,
tipc socket is the first user benefiting from this enhancement.
v2 changes:
- fix the issue of waking up worker thread under a wrong condition in
patch #2, which is pointed by Thomas.
- move a comment from rhashtable_inser() to rhashtable_wakeup_worker()
according to Thomas's suggestion in patch #2.
- indent the third line of condition statement in
rhashtable_wakeup_worker() to inner bracket in patch #2.
- drop patch #3 of v1 series
- fix an issue of being unable to remove an object from hash table in
certain special case in patch #4.
- involve a new patch #5 to avoid unnecessary wakeup for worker queue
thread
- involve a new patch #6 to initialize atomic "nelems" variable
- adjust "nelem_hint" value from 256 to 192 avoiding to unnecessarily
to shrink hash table from the beginning phase in patch #7.
v1 changes:
But before rhashtable_lookup_insert() is involved, the following
optimizations need to be first done:
- simplify rhashtable_lookup by reusing rhashtable_lookup_compare()
- introduce rhashtable_wakeup_worker() to further reduce duplicated
code in patch #2
- fix an issue in patch #3
- involve rhashtable_lookup_insert(). But in this version, we firstly
use rhashtable_lookup() to search duplicate key in both old and new
bucket table; secondly introduce another __rhashtable_insert() helper
function to reduce the duplicated code between rhashtable_insert()
and rhashtable_lookup_insert().
- add patch #5 into the series as it depends on above patches. But in
this version, no change is made comparing with its previous version.

As tipc reference table is statically allocated, its memory size
requested on stack initialization stage is quite big even if the
maximum port number is just restricted to 8191 currently, however,
the number already becomes insufficient in practice. But if the
maximum ports is allowed to its theory value - 2^32, its consumed
memory size will reach a ridiculously unacceptable value. Apart from
this, heavy tipc users spend a considerable amount of time in
tipc_sk_get() due to the read-lock on ref_table_lock.
If tipc reference table is converted with generic rhashtable, above
mentioned both disadvantages would be resolved respectively: making
use of the new resizable hash table can avoid locking on the lookup;
smaller memory size is required at initial stage, for example, 256
hash bucket slots are requested at the beginning phase instead of
allocating the entire 8191 slots in old mode. The hash table will
grow if entries exceeds 75% of table size up to a total table size
of 1M, and it will automatically shrink if usage falls below 30%,
but the minimum table size is allowed down to 256.
Also converts ref_table_lock to a separate mutex to protect hash table
mutations on write side. Lastly defers the release of the socket
reference using call_rcu() to allow using an RCU read-side protected
call to rhashtable_lookup().

When remove an object from hash table, we currently only traverse old
bucket table to check whether the object exists. If the object is not
found in it, we will try again. But in the second search loop, we still
search the object from the old table instead of future table. As a
result, the object may be not removed from hash table especially when
resizing is currently in progress and the object is just saved in the
future table.

By the way, as long as the both "future_tbl" and "tbl" bucket table
pointers point to the same bucket array, we should try to wake up
the resizing worker thread, otherwise, it indicates the work of
resizing hash table is not finished yet. However, currently we will
wake up the worker thread only when the two pointers point to
different bucket array. Obviously this is wrong. So, the issue is

Intel Wired LAN Driver Updates 2015-01-06
This series contains fixes to i40e only.
Jesse provides a fix for when the driver was polling with interrupts
disabled the hardware would occasionally not write back descriptors.
His fix causes the driver to detect this situation and force an interrupt
to fire which will flush the stuck descriptor.
Anjali provides a couple of fixes, the first corrects an issue where
the receive port checksum error counter was incrementing incorrectly with
UDP encapsulated tunneled traffic. The second fix resolves an issue where
the driver was examining the outer protocol layer to set the inner protocol
layer checksum offload. In the case of TCP over IPv6 over an IPv4 based
VXLAN, the inner checksum offloads would be set to look for IPv4/UDP
instead of IPv6/TCP, so fixed the issue so that the driver will look at
the proper layer for encapsulation offload settings.
v2: fixed a bug in patch 01 of the series, where the interrupt rate impacted
4 port workloads by reducing throughput.

Next batch of atomic work. Most important is the propertification from Rob

Big differences compared to earlier revisions:
- Core properties are now fully handled by the core, drivers can only
handle driver-specific properties.
- Atomic props&ioctl are opt-in per file_priv, userspace needs to
explicitly ask for it (like universal plane support).
- For now all hidden behind the atomic module option until this has
settled a bit.
- Atomic modesets are currently not possible since the exact abi for how
to handle the mode property is still under discussion.
Besides this some cleanup patches from me and the addition of per-object

Charles Shirron and Paul Cassella from Cray Inc have reported kswapd
stuck in a busy loop with nothing left to balance, but
kswapd_try_to_sleep() failing to sleep. Their analysis found the cause
to be a combination of several factors:
1. A process is waiting in throttle_direct_reclaim() on pgdat->pfmemalloc_wait
2. The process has been killed (by OOM in this case), but has not yet been
scheduled to remove itself from the waitqueue and die.
3. kswapd checks for throttled processes in prepare_kswapd_sleep():
if (waitqueue_active(&pgdat->pfmemalloc_wait)) {
wake_up(&pgdat->pfmemalloc_wait);
return false; // kswapd will not go to sleep
}
However, for a process that was already killed, wake_up() does not remove
the process from the waitqueue, since try_to_wake_up() checks its state
first and returns false when the process is no longer waiting.
4. kswapd is running on the same CPU as the only CPU that the process is
allowed to run on (through cpus_allowed, or possibly single-cpu system).
5. CONFIG_PREEMPT_NONE=y kernel is used. If there's nothing to balance, kswapd
encounters no voluntary preemption points and repeatedly fails
prepare_kswapd_sleep(), blocking the process from running and removing
itself from the waitqueue, which would let kswapd sleep.
So, the source of the problem is that we prevent kswapd from going to
sleep until there are processes waiting on the pfmemalloc_wait queue,
and a process waiting on a queue is guaranteed to be removed from the
queue only when it gets scheduled. This was done to make sure that no
process is left sleeping on pfmemalloc_wait when kswapd itself goes to
sleep.
However, it isn't necessary to postpone kswapd sleep until the
pfmemalloc_wait queue actually empties. To prevent processes from being
left sleeping, it's actually enough to guarantee that all processes
waiting on pfmemalloc_wait queue have been woken up by the time we put
kswapd to sleep.
This patch therefore fixes this issue by substituting 'wake_up' with
'wake_up_all' and removing 'return false' in the code snippet from
prepare_kswapd_sleep() above. Note that if any process puts itself in
the queue after this waitqueue_active() check, or after the wake up
itself, it means that the process will also wake up kswapd - and since
we are under prepare_to_wait(), the wake up won't be missed. Also we
update the comment prepare_kswapd_sleep() to hopefully more clearly
describe the races it is preventing.
