Cornelia Huck 94bb063312 [S390] rework of channel measurement facility.
Fixes for several channel measurement facility bugs:
* Blocks copied from the hardware might not be consistent. Solve this
  by moving the copying into idle state and repeating the copying.
* avg_sample_interval changed with every read, even though no new block
  was available. Solve this by storing a timestamp when the last new
  block was received.
* Several locking issues.
* Measurements were not reenabled after a disconnected device became
  available again.
* Remove #defines for ioctls that were never implemented.

Cornelia Huck b4f7b1ee57 [S390] cio chpid offline.
After setting a path to a dasd offline at the SE, I/O hangs on that
dasd for 5 minutes, then continues.
I/O for which an interrupt will not be reported after the channel
path has been disabled was not terminated by the common I/O layer,
causing the dasd MIH to hit after 5 minutes.

Be more aggressive in terminating I/O after setting a channel path
offline. Also make sure to generate a fake irb if the device
driver issues an I/O request after being notified of the killed
I/O and clear residual information from the irb before trying to
start the delayed verification.

Martin Schwidefsky 132fab1363 [S390] modular 3270 driver.
The initial i/o to a 3270 device is done using the static module variables
raw3270_init_data and raw3270_init_request. If the 3270 device driver is
built as a module and gets loaded above 2GB, the initial i/o will fail
because these variables will get addresses > 2GB. To make it work the
two variables are moved to struct raw3270 and the data structure is
allocated with GFP_DMA.

Cornelia Huck 887ab59929 [S390] ccwgroup device unregister.
Work around the problem that a device cannot be unregistered from
driver_for_each_device() because of klist node refcounting: Get device
after device owned by the driver to be unregistered with driver_find_device()
and then unregister it. This works because driver_get_device() gets us out of
the region of the elevated klist node refcount. driver_find_device() will
always get the next device in the list after the found one has been
unregistered.

Herbert Xu 7967168cef [NET]: Merge TSO/UFO fields in sk_buff
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not
going to scale if we add any more segmentation methods (e.g., DCCP).  So
let's merge them.

They were used to tell the protocol of a packet.  This function has been
subsumed by the new gso_type field.  This is essentially a set of netdev
feature bits (shifted by 16 bits) that are required to process a specific
skb.  As such it's easy to tell whether a given device can process a GSO
skb: you just have to and the gso_type field and the netdev's features
field.

I've made gso_type a conjunction.  The idea is that you have a base type
(e.g., SKB_GSO_TCPV4) that can be modified further to support new features.
For example, if we add a hardware TSO type that supports ECN, they would
declare NETIF_F_TSO | NETIF_F_TSO_ECN.  All TSO packets with CWR set would
have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO
packets would be SKB_GSO_TCPV4.  This means that only the CWR packets need
to be emulated in software.

Klaus Wacker 27eb5ac8f0 [PATCH] s390: lcs driver bug fixes and improvements [1/2]
Several problems occured with lcs device driver:
	 - device not operational anymore after cable pull/plug-in.
       	 - unpredictable results occured, e.g. kernel panic
	   using cards of type QD8F.
	 - STOPLAN and delete multicast address command
           were not proper recognized by OSA card under heavy network workload.
       	 - channel/device error checks missing in interrupt handler.
	To fix all problems at once recovery of lcs devices has been improved.
	missing error checks in lcs interrupt handler has been added.
	Once a hardware problem occurs lcs will recover the device now properly.

From: Frank Blaschka <Frank.Blaschka@de.ibm.com>
From: Frank Pavlic <fpavlic@de.ibm.com>

        - fix fake_ll during initial device bringup. fake_ll was
	  not active after first start of the device.
	  Problem only occured when qeth was built without IPV6 support.
        - avoid skb usage after invocation of qeth_flush_buffers,
	  because skb might already be freed.
        - remove yet another useless netif_wake_queue in
	  qeth_softsetup_ipv6 since this function is only called
	  when device is going online. In this case card->state will
	  never be in state UP. So let the net_device queue down .

Christian Borntraeger 40ac6b204c [PATCH] s390: fix slab debugging
With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work.  The problem is
that the qib structure embedded in the qeth_irq structure needs an alignment
of 256 but kmalloc only guarantees an alignment of 8.  When using SLAB
debugging the alignment of qeth_irq is not sufficient for the embedded qib
structure which causes all users of qdio (qeth and zfcp) to stop working.
Allocate qeth_irq structure with __get_free_page.  That wastes a small amount
of memory (~2500 bytes) per online adapter.

Horst Hummel 39ccf95e28 [PATCH] s390: dasd ioctl never returns
The dasd state machine is not designed to enable an unformatted device, since
'unformatted' is a final state.  The BIODASDENABLE ioctl calls
dasd_enable_device() which never returns if the device is in this special
state.  Return -EPERM in dasd_increase_state for unformatted devices to make
dasd_enable_device terminate.  Note: To get such an unformatted device online
it has to be re-analyzed.  This means that the device needs to be disabled
prior to re-enablement.

Hi jeff,
after the first shot I sent to you did not apply I
resend  two new patches I've made today to remove tty from ctc network driver.
Please apply ....

Thank you ...

Frank

From: Peter Tiedemann <ptiedem@de.ibm.com>
        [1/2]:
        tty support code will be removed from the ctc network device driver.
        Today we have a couple of alternatives which are performing much
        better. The second thing is that ctc should be a network
        device driver only.
        We should not mix tty and networking here.
        This first patch will remove the tty code from ctcmain.c .
        It also removes the build entry from the Makefile as well as TTY
        definitions from ctcmain.h.
        The second patch will remove two files, ctctty.c and ctctty.h.

Eric Rossman 96641ee1e4 [PATCH] s390: CEX2A crt message length
Undetected edge case for CRT messages to CEX2A caused length to be too short,
thus truncating the message.  The solution was to check a different variable
which actually determines which key type is being used.

Increment version number in z90main.c to correct level of 1.3.3, fix copyright
year and add comment about bitlength limit of CEX2A.

Michael Holzheu 5f38433885 [PATCH] s390: fix endless retry loop in tape driver
If a tape device is assigned to another host, the interrupt for the assign
operation comes back with deferred condition code 1.  Under some conditions
this can lead to an endless loop of retries.  Check if the current request is
still in IO in deferred condition code handling and prevent retries when the
request has already been cancelled.

Michael Holzheu 4cd190a736 [PATCH] s390: tape operation abortion leads to panic
When a request is aborted because of a signal, we currently stop the request
via csh, but we do not wait for the interrupt of csh in any case.  We free the
request structure and therefore when the interrupt for the csh operation is
presented, the request object is no longer valid and an invalid callback
pointer is used.

To fix this wait until the interrupt for csh arrives and until
wait_event_interruptible() does not return -ERESTARTSYS.

This avoids searching a linear list on every call to dasd_ioctl(), and allows

moving the check for bdev->bd_disk->private_data from the individual functions
to dasd_ioctl.  (I think it can't actually every be NULL, but let's keep that

(2) Avoid scsi_device allocation during registration of an remote port.
(Would be done during fc_scsi_scan_rport.)

(3) Fix queuecommand behaviour when an zfcp unit is blocked.

DASD allows to open a device as soon as gendisk is registered, which means the
device is a fake device (capacity=0) and we do know nothing about blocksize
and partitions at that point of time.  In case the device is opened by
someone, the bdev and inode creation is done with the fake device info and the
following partition detection code is just using the wrong data.

To avoid this modify the DASD state machine to make sure that the open is
rejected until the device analysis is either finished or an unformatted device
was detected.

Peter Oberparleiter 25fab9ebac [PATCH] s390: fix sclp memory corruption in tty pages list
When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface.  Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list.  The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.

To avoid this remove the busy retry limit and increase retry intervals.

Alan Cox 33f0f88f1c [PATCH] TTY layer buffering revamp
The API and code have been through various bits of initial review by
serial driver people but they definitely need to live somewhere for a
while so the unconverted drivers can get knocked into shape, existing
drivers that have been updated can be better tuned and bugs whacked out.

This replaces the tty flip buffers with kmalloc objects in rings. In the
normal situation for an IRQ driven serial port at typical speeds the
behaviour is pretty much the same, two buffers end up allocated and the
kernel cycles between them as before.

When there are delays or at high speed we now behave far better as the
buffer pool can grow a bit rather than lose characters. This also means
that we can operate at higher speeds reliably.

For drivers that receive characters in blocks (DMA based, USB and
especially virtualisation) the layer allows a lot of driver specific
code that works around the tty layer with private secondary queues to be
removed. The IBM folks need this sort of layer, the smart serial port
people do, the virtualisers do (because a virtualised tty typically
operates at infinite speed rather than emulating 9600 baud).

Finally many drivers had invalid and unsafe attempts to avoid buffer
overflows by directly invoking tty methods extracted out of the innards
of work queue structs. These are no longer needed and all go away. That
fixes various random hangs with serial ports on overflow.

The other change in here is to optimise the receive_room path that is
used by some callers. It turns out that only one ldisc uses receive room
except asa constant and it updates it far far less than the value is
read. We thus make it a variable not a function call.

I expect the code to contain bugs due to the size alone but I'll be
watching and squashing them and feeding out new patches as it goes.

Because the buffers now dynamically expand you should only run out of
buffering when the kernel runs out of memory for real.  That means a lot of
the horrible hacks high performance drivers used to do just aren't needed any
more.

Description:

tty_insert_flip_char is an old API and continues to work as before, as does
tty_flip_buffer_push() [this is why many drivers dont need modification].  It
does now also return the number of chars inserted

There are also

tty_buffer_request_room(tty, len)

which asks for a buffer block of the length requested and returns the space
found.  This improves efficiency with hardware that knows how much to
transfer.

and tty_insert_flip_string_flags(tty, str, flags, len)

to insert a string of characters and flags

For a smart interface the usual code is

    len = tty_request_buffer_room(tty, amount_hardware_says);
    tty_insert_flip_string(tty, buffer_from_card, len);

More description!

At the moment tty buffers are attached directly to the tty.  This is causing a
lot of the problems related to tty layer locking, also problems at high speed
and also with bursty data (such as occurs in virtualised environments)

I'm working on ripping out the flip buffers and replacing them with a pool of
dynamically allocated buffers.  This allows both for old style "byte I/O"
devices and also helps virtualisation and smart devices where large blocks of
data suddenely materialise and need storing.

So far so good.  Lots of drivers reference tty->flip.*.  Several of them also
call directly and unsafely into function pointers it provides.  This will all
break.  Most drivers can use tty_insert_flip_char which can be kept as an API
but others need more.

At the moment I've added the following interfaces, if people think more will
be needed now is a good time to say

 int tty_buffer_request_room(tty, size)

Try and ensure at least size bytes are available, returns actual room (may be
zero).  At the moment it just uses the flipbuf space but that will change.
Repeated calls without characters being added are not cumulative.  (ie if you
call it with 1, 1, 1, and then 4 you'll have four characters of space.  The
other functions will also try and grow buffers in future but this will be a
more efficient way when you know block sizes.

 int tty_insert_flip_char(tty, ch, flag)

As before insert a character if there is room.  Now returns 1 for success, 0
for failure.

 int tty_insert_flip_string(tty, str, len)

Insert a block of non error characters.  Returns the number inserted.

 int tty_prepare_flip_string(tty, strptr, len)

Adjust the buffer to allow len characters to be added.  Returns a buffer
pointer in strptr and the length available.  This allows for hardware that
needs to use functions like insl or mencpy_fromio.

Christoph Hellwig a885c8c431 [PATCH] Add block_device_operations.getgeo block device method
HDIO_GETGEO is implemented in most block drivers, and all of them have to
duplicate the code to copy the structure to userspace, as well as getting
the start sector.  This patch moves that to common code [1] and adds a
->getgeo method to fill out the raw kernel hd_geometry structure.  For many
drivers this means ->ioctl can go away now.

[1] the s390 block drivers are odd in this respect.  xpram sets ->start
    to 4 always which seems more than odd, and the dasd driver shifts
    the start offset around, probably because of it's non-standard
    sector size.

Add support for multiple subchannel sets.  Works with arbitrary devices in
subchannel set 1 and is transparent to device drivers.  Although currently
only two subchannel sets are available, this will work with the architectured
maximum number of subchannel sets as well.

Frank Pavlic 8129ee1642 [PATCH] s390: qdio V=V pass-through
New feature V=V qdio pass-through.

QDIO and HiperSockets processing in z/VM V=V guest environments (as well as
V=R with z/VM running in LPAR mode) requires shadowing of all QDIO
architecture queue elements.  Especially the shadowing of SBALs and SLSBs
structures in the hypervisor, and the need to issue SIGA SYNC operations to
observe state changes, eventually causes significant CPU processing overhead
in the hypervisor.

The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and
SLSBs.  This significantly reduces the hypervisor overhead for QDIO based I/O.

Tejun Heo 8ffdc6550c [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()
add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn().  there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently).  this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().

for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice.  imho, this can also
help the generic command-carrying request jens is working on.

Tim Schmielau 4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

Ursula Braun 500f83abdc [PATCH] s390: introducing support in qeth for new OSA CHPID type OSN
This patch introduces new feature in qeth:
	qeth enhancement provides the device driver support for
        the Communication Controller for Linux on System z9 and zSeries
        (CCL), which is software that enables running the Network Control
        Program (NCP) on a zSeries machine. The OSA CDLC support is based
        on a new IBM mainframe CHPID type called Open Systems Adaper for
        NCP (OSN). In case of OSN qeth communicates with the type-OSN
        OSA-card on one hand, and with the CCL-kernel-component Network
        Device Handler (NDH) on the other.

	- allocate qdio structures in DMA-area
	- schedule recovery of appropriate card
	  when cable has been inserted again.

	- write sequence number in skb->cb for SNA protocol which

Herbert Xu e5ed639913 [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl
The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.

1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().

There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition.  I've marked it as such so that we remember to fix it.

This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

The new traces improve debugging of problems with zfcp, scsi-stack,
multipath and hardware in the SAN. san_dbf traces things like ELS and
CT commands, hba_dbf saves HBA specific information of requests, and
scsi_dbf saves FCP and SCSI specific information of requests. Common
to all new DBFs is that they provide a so called structured view. This
significantly improves readability of the traces.

static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

Christian Borntraeger 3e5ea09844 [PATCH] s390: use __cpcmd in vmcp_write
vmcp_write uses GPF_DMA for the memory allocation of the response buffer, so
it can use the low level function __cpcmd directly, no need to call the
wrapper.

Horst Hummel d61f6f3d8b [PATCH] s390: fba dasd i/o errors
The FBA discipline does not use retries for failed requests.  A request fails
after the first unsuccessful start attempt.  There are some rare conditions
(e.g.  CIO path recovery) in which the start of an i/o on a fba device can
fail.  A tiny amount of retries is therefore reasonable.
