pohmelfs wants to use CONNECTOR, so it selects CONNECTOR,
but when CONFIG_NET is not enabled, connector.c will not build,
since select does not follow the dependency chain.
Selecting NET is not a good idea, since that would build lots
of code that someone seemingly didn't want to build/store
and kconfig shouldn't do that behind someone's back.
pohmelfs should depend on NET since it uses network interfaces.
pohmelfs also uses CRYTPO and selects 2 cipher symbols, but
it should also select the top-level CRYPTO symbol since
kconfig dependency chains are not followed.
(found by inspection)
This allows the POHMELFS_CRYPTO option to depend only on
POHMELFS and makes the kconfig menu align properly.
Also fix minor typos & line lengths in kconfig help text.
Drop CONFIG_* in kconfig symbols in Kconfig file.

Each transction is an object, which may embed multiple commands

maintain high data integrity and do not desynchronize filesystem state
in case of network or server failures.

This is a main network processing patch. It includes
both low-level socket machinery, zero-copy sending helpers,
receiving and parsing callbacks and mainly logical
commands handlers.
POHMELFS uses async network approach, when every command
can be separated from its answer and received after some
time after the request during which another lots of commands
can be injected into the network and replies to them received.
With read operation balancing between multiple hosts it is possible
that operations will arrive out of order and this is handled
by the transaction mechanism described partially here.
Having a transaction to guard the set of logically compound operations
allows to send data without thinking about its status and using
zero-copy sending mechanism, since transaction will receive explicit
acks from the servers when they are completed.
This patch also contains header with network srtuctures, commands
and short comments on how they are used.

DST may fully encrypt the data channel in case of untrusted channel and implement
strong checksum of the transferred data. It is possible to configure algorithms
and crypto keys, they should match on both sides of the network channel.
Crypto processing does not introduce noticeble performance overhead, since DST
uses configurable pool of threads to perform crypto processing.
This patch introduces crypto processing helpers and crypto engine initialization:
glueing with the crypto layer, allocation and initialization of the crypto
processing thread pool, allocation of the cached pages, which are used to temporary
encrypt data into, since it is forbidden to encrypt data in-place, since pages
are used by the higher layers.

DST uses transaction model, when each store has to be explicitly acked
from the remote node to be considered as successfully written. There
may be lots of in-flight transactions. When remote host does not ack
the transaction it will be resent predefined number of times with specified
timeouts between them. All those parameters are configurable. Transactions
are marked as failed after all resends completed unsuccessfully, having
long enough resend timeout and/or large number of resends allows not to
return error to the higher (FS usually) layer in case of short network
problems or remote node outages. In case of network RAID setup this means
that storage will not degrade until transactions are marked as failed, and
thus will not force checksum recalculation and data rebuild. In case of
connection failure DST will try to reconnect to the remote node automatically.
DST sends ping commands at idle time to detect if remote node is alive.
Because of transactional model it is possible to use zero-copy sending
without worry of data corruption (which in turn could be detected by the
strong checksums though).
Transactions are handled in this patch: allocation/freeing/completion,
scanning for stall and to-be-resent transactions and overall management
of the storing tree.

Kernel currently does not allow to queue work into some entity which
will perform it in the process context and have simple way to extend
number of worker and work with them not as separate objects, but with
pool as a whole. So thread pool model was implemented in the DST.
Thread pool abstraction allows to schedule a work to be performed
on behalf of kernel thread. One does not operate with threads itself,
instead user provides setup and cleanup callbacks for thread pool itself,
and action and cleanup callbacks for each submitted work.
Each worker has private data initialized at creation time and data,
provided by user at scheduling time.
When action is being performed, thread can not be used by other users,
instead they will sleep until there is free thread to pick their work.
Thread pool is used for crypto processing of incoming and outgoing IO
requests to reduce the overall overhead.

Replacing the use of kernel_thread() with kthread_run(). But as
kthread_run() returned a task structure, as compared with
kernel_thread() returning a PID, it was found to be more efficient to
store the task structure pointer as a field data instead of PID
pointer. On top of modifying the field to store task structure
pointer, the initialization of the field (assigned to
THREAD_PID_INIT_VALUE) was also found unnecessary - as no where it is

Staging: rt2860: Ported v1.7.1.1 changes into v1.8.0.0, becoming v1.8.1.1
When RaLink released rt2860 v1.7.0.0, it lacked proper support for both WEP
and WPA/WPA2 encryption. Either was possible, but the module had to be
compiled to support only one or the other, never both.
Since the EeePC was the most common device with this hardware (and these
users were complaining to RaLink that WPA/WPA2 encryption didn't work)
RaLink released a fix as an "eeepc-specific" version of this driver, v1.7.1.1
Unfortunately, when v1.8.0.0 was released, this WPA/WPA2 fix was never
included.
What complicates things further is that RaLink has no interest in
continuing work on this Linux driver for their hardware.
This commit ports the changes introduced in v1.7.1.1 into the v1.8.0.0
release, upgrading the kernel's module to v1.8.1.1

we just came out shouting. This rollbacks all the successful operation
before skb allocation fails and then returns.

netmos serial/parallel adapters come in different flavour differing only
by the number of parallel and serial ports, which are encoded in the
subdevice ID.
Last fix of Christian Pellegrin for 9855 2P2S broke support for 9855 1P4S,
and works only by side-effect for the first parallel port of a 2P2S, as
this first parallel port is found by reading the second addr entry of
(struct parport_pc_pci) cards[netmos_9855], which is not initialized, and
hence has value 0, which happens to be the BAR of the first parallel port.
netmos_9xx5_combo entry in (struct parport_pc_pci) cards[], which is used
for a 9845 1P4S must also be fixed for the parallel port support when
there are 4 serial ports because this entry currently gives 2 as BAR index
for the parallel port. Actually, in this case, BAR 2 is the 3rd serial
port while the parallel port is at BAR 4.
I fixed 9845 1P4S and 9855 1P4S support, while preserving 9855 2P2S support,
- by creating a netmos_9855_2p entry and using it for 9855 boards with 2
parallel ports : 9855 2P2S and 9855 2P0S boards,
- and by allowing netmos_parallel_init to change not only the number of
parallel ports (0 or 1), but making it also change the BAR index of the
parallel port when the serial ports are before the parallel port.
PS: the netmos_9855_2p entry in (struct pciserial_board)
pci_parport_serial_boards[] is needed because netmos_parallel_init has no
clean way to replace FL_BASE2 by FL_BASE4 in the description of the serial
ports in function of the number of parallel ports on the card.
Tested with 9845 1P4S, 9855 1P4S and 9855 2P2S boards.

This adds support for an EDAC memory controller adaptation driver for the
"ibm,sdram-4xx-ddr2" ECC controller realized in the AMCC PowerPC 405EX[r].
At present, this driver has been developed and tested against the
controller realization in the AMCC PPC405EX[r] on the AMCC Kilauea and
Haleakala boards (256 MiB w/o ECC memory soldered onto the board) and a
proprietary board based on those designs (128 MiB ECC memory, also
soldered onto the board).
In the future, dynamic feature detection and handling needs to be added
for the other realizations of this controller found in the 440SP, 440SPe,
460EX, 460GT and 460SX.
Eventually, this driver will likely be evolved and adapted to the above
variant realizations of this controller as well as broken apart to handle
the other known ECC-capable controllers prevalent in other PPC4xx
processors:
- IBM SDRAM (405GP, 405CR and 405EP) "ibm,sdram-4xx"
- IBM DDR1 (440GP, 440GX, 440EP and 440GR) "ibm,sdram-4xx-ddr"
- Denali DDR1/DDR2 (440EPX and 440GRX) "denali,sdram-4xx-ddr2"

The logging API needs an extra function to make cluster mirroring
possible. This new function allows us to check whether a mirror
region is being recovered on another machine in the cluster. This
helps us prevent simultaneous recovery I/O and process I/O to the
same locations on disk.
Cluster-aware log modules will implement this function. Single
machine log modules will not. So, there is no performance
penalty for single machine mirrors.

We need to check if the exception was completed after dropping the lock.
After regaining the lock, __find_pending_exception checks if the exception
was already placed into &s->pending hash.
But we don't check if the exception was already completed and placed into
&s->complete hash. If the process waiting in alloc_pending_exception was
delayed at this point because of a scheduling latency and the exception
was meanwhile completed, we'd miss that and allocate another pending
exception for already completed chunk.
It would lead to a situation where two records for the same chunk exist
and potential data corruption because multiple snapshot I/Os to the
affected chunk could be redirected to different locations in the
snapshot.

If someone sends signal to a process performing synchronous dm-io call,
the kernel may crash.
The function sync_io attempts to exit with -EINTR if it has pending signal,
however the structure "io" is allocated on stack, so already submitted io
requests end up touching unallocated stack space and corrupting kernel memory.
sync_io sets its state to TASK_UNINTERRUPTIBLE, so the signal can't break out
of io_schedule() --- however, if the signal was pending before sync_io entered
while (1) loop, the corruption of kernel memory will happen.
There is no way to cancel in-progress IOs, so the best solution is to ignore
signals at this point.

With my previous patch to save bi_io_vec, the size of dm_raid1_read_record
is significantly increased (the vector list takes 3072 bytes on 32-bit machines
and 4096 bytes on 64-bit machines).
The structure dm_raid1_read_record used to be allocated with kmalloc,
but kmalloc aligns the size on the next power-of-two so an object
slightly greater than 4096 will allocate 8192 bytes of memory and half of
that memory will be wasted.
This patch turns kmalloc into a slab cache which doesn't have this
padding so it will reduce the memory consumed.

Device mapper saves and restores various fields in the bio, but it doesn't save
bi_io_vec. If the device driver modifies this after a partially successful
request, dm-raid1 and dm-multipath may attempt to resubmit a bio that has
bi_size inconsistent with the size of vector.
To make requests resubmittable in dm-raid1 and dm-multipath, we must save
and restore the bio vector as well.
To reduce the memory overhead involved in this, we do not save the pages in a
vector and use a 16-bit field size if the page size is less than 65536.

Original comment (Karsten):
On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time
after BIOS has run, IntrStatus reads 5 after chip has been reset.
IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen
after chip reset instead of before.
Remark (Francois):
Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR,
the bug reveals itself with a typical "interrupt 0025 in poll" message
at startup. In retrospect, the message should had been read as an hint of
an unexpected hardware state several months ago :o(

Impact: Fix
Yinghai Lu found one system with 82575EB where, in the kernel that is
kexeced, probe igb failed with -2, the reason being that the adapter
could not be brought back from D3 by the kexec kernel, most probably
due to quirky hardware (it looks like the same behavior happened on
forcedeth).
Prevent igb from putting the adapter into D3 during shutdown except
when we going to power off the system. For this purpose, seperate
igb_shutdown() from igb_suspend() and use the appropriate PCI PM
