Sebastian Ott 00d5bdd17b s390/lcs: switch to ccwgroup_create_dev
Switch to the new ccwgroup_create_dev interface. Also wrap device
attributes in a struct device_type and let the driver core create
these attributes automagically.

Heiko Carstens 521674e4ff s390/claw: remove "eieio" calls
If the code really depends on ordering it's already racy. The additional
memory barriers (eieio) don't help with that.
If the code is not racy the memory barriers also aren't needed.

In any case, just remove them.

Jan Glauber 1549d13f4c s390/qdio: Cleanup error handling to drivers
Various improvements of qdio error reporting to the
upper-layer drivers (qeth, zfcp):

- Split QDIO_ERROR_ACTIVATE_CHECK_CONDITION into:

  QDIO_ERROR_ACTIVATE: qdio termination interrupt
  QDIO_ERROR_GET_BUF_STATE: QIOASSIST eqbs error
  QDIO_ERROR_SET_BUF_STATE: QIOASSIST sqbs error

  Add QDIO_ERROR_FATAL / QDIO_ERROR_TEMPORARY masks
  to ease recovery decision in upper-layer drivers.

- Don't (ab-)use qdio handler errors as return codes
  for do_QDIO but use standard error codes:

  -ENOBUFS: temporary target CC=2 condition
  -EBUSY: unresolved SIGA-W CC=2 busy condition
  -EIO: I/O error (CC=1, CC=3)

- Remove unneeded memory clobber from SIGA-R
- Remove EX_TABLE entry on SIGA-W, we want to see these errors

There exist qeth sysfs blkt attributes to change the default blkt
values. But blkt changes are reset during online setting due to a 2nd

Belinda Thompson 205a8b649c ctcm: use correct idal word list for ctcmpc
Communication Server Linux uses the ctcmpc code of the ctcm driver.
Sending problems have shown up caused by a wrong idal word list for
the first ccw. Function ctcmpc_chx_txdone() invokes the function
to prepare the idal word list without setting an appropriate length
for the first ccw, which may lead to an incomplete idal word list.
This patch sets the maximum buffer size as data length of the first
ccw. Thus correct idal word lists are guaranteed in all cases.

We've moving to a model where dst_entry objects to not have
a reference to the associated neighbour entry, instead such
neighbours must be looked up on-demand.

Here in qeth_l3_fill_header() it's actually much simpler to
use the information in the route itself.  The code is
already conditionalized upon protocol type.

Alan Stern fde25a9b63 Driver core: driver_find() drops reference before returning
As part of the removal of get_driver()/put_driver(), this patch
(as1510) changes driver_find(); it now drops the reference it acquires
before returning.  The patch also adjusts all the callers of
driver_find() to remove the now unnecessary calls to put_driver().

In addition, the patch adds a warning to driver_find(): Callers must
make sure the driver they are searching for does not get unloaded
while they are using it.  This has always been the case; driver_find()
has never prevented a driver from being unregistered or unloaded.
Hence the patch will not introduce any new bugs.  The existing callers
all seem to be okay in this respect, however I don't understand the
video drivers well enough to be certain about them.

Frank Blaschka b333293058 qeth: add support for af_iucv HiperSockets transport
This patch extends the HiperSockets device driver to send and receive
af_iucv traffic over HiperSockets transport.
TX: Driver uses new asynchronous delivery of storage blocks to pass
    flow control/congestion information from the HiperSockets microcode
    to the af_iucv socket.
RX: Memory for incoming traffic is preallocated and passed to
    HiperSockets layer. If receiver is not capable to clean its buffers
    shared with HiperSockets and pass new memory to the HiperSockets
    layer this will cause flow control/congestion events on the
    sender.

Ursula Braun 394234406c qeth: postpone open till recovery is finished
The open function of qeth is not executed if the qeth device is in
state DOWN or HARDSETUP. A recovery switches from state SOFTSETUP to
HARDSETUP to DOWN to HARDSETUP and back to SOFTSETUP. If open and
recover are running concurrently, open fails if it hits the states
HARDSETUP or DOWN. This patch inserts waiting for recovery finish
in the qeth open functions to enable successful qeth device opening
in spite of a running recovery.

Jan Glauber 3d6c76ff32 [S390] qdio: outbound tasklet scan threshold
Introduce a scan treshold for the qdio outbound queues. By setting the
threshold the driver can tell qdio after how much used SBALs qdio
should schedule the outbound tasklet that scans the queue for finished
SBALs. The threshold is specific by the drivers because a
Hipersockets device is much faster in utilizing outbound buffers than a
ZFCP or OSA device.

The default values after how many used SBALs the tasklet should run are:

OSA:          > 31 SBALs
Hipersockets: > 7 SBALs
zfcp:         > 55 SBALs

Device initialization of a qeth device contains a STARTLAN step.
This step may fail, if cable is not yet plugged in. The qeth device
stays in state HARDSETUP until cable is plugged in. This prevents
further preparational initialization steps of the qeth device and
its network interface. This patch makes sure initialization of qeth
device continues, even though cable is not yet plugged in.
Once carrier is available, qeth is notified, triggers a recovery
which results in a working network interface.

This patch adds NAPI support to the qeth layer 2 and layer 3
discipline. It is important to understand that we can not enable/disable
IRQs as usual, we have to use the corresponding new QDIO interface.
Also to not overdraw the budget we have to stop and restart buffer
processing at any point during processing a bulk of QDIO buffers.
Having the driver NAPI enabled it is possible to turn on GRO for the
layer 3 discipline.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

to receive z/VM CP special messages (SMSG) starting with "APP".

When the callback is called for special messages, the driver creates
an uevent for the received message.  The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.

udev rules can be used to trigger application specific actions through

Ursula Braun 84b66683db qeth: avoid recovery during device online setting
If a qeth device is set online, several initialisation steps are
performed. If a failure in one of these steps occurs, the qeth
device is reset into DOWN state. If due to the failure a qeth recovery
is scheduled and started in another thread, this might cause all kinds
of conflicts, even a kernel panic. The patch forbids scheduling of a
qeth recovery while online processing is performed till the card is in
state SOFTSETUP.

The cu3088-driver used as common base for lcs- and ctcm-devices
makes it difficult to assign the appropriate driver to an lcs-device
or a ctcm-device. This patch eliminates the cu3088-driver and thus
the root device "cu3088". Path /sys/devices/cu3088 is replaced with
the pathes /sys/devices/lcs and /sys/devices/ctcm.

Patch is based on a proposal from Cornelia Huck.

This patch updates misc percpu related symbols such that percpu

two purposes of decreasing the possibility of global percpu symbol
collision and allowing dropping per_cpu__ prefix from percpu symbols.

* drivers/crypto/padlock-aes.c: s/last_cword/paes_last_cword/

* drivers/lguest/x86/core.c: s/last_cpu/lg_last_cpu/

* drivers/s390/net/netiucv.c: rename the variable used in a macro to
  avoid clashing with percpu symbol

* arch/mn10300/kernel/kprobes.c: replace current_ prefix with cur_ for
  static variables.  Please note that percpu symbol current_kprobe
  can't be changed as it's used by generic code.

Partly based on Rusty Russell's "alloc_percpu: rename percpu vars

my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
   on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

Martin Schwidefsky 6a1d96dced [S390] pm: smsgiucv power management callbacks.
Create dummy iucv-device to get control when the system is suspended
and resumed. Server the smsg iucv path on suspend, reestablish the
path on resume.

Ursula Braun 1175b257c8 [S390] pm: netiucv power management callbacks.
Patch establishes a dummy netiucv device to make sure iucv is notified
about suspend/resume even if netiucv is the only loaded iucv-exploting
module without any real net_device defined.

The PM freeze callback closes all open netiucv connections. Thus the
corresponding iucv path is removed.
The PM thaw/restore callback re-opens previously closed netiucv
connections.

Greg Kroah-Hartman dff59b64af s390: remove driver_data direct access of struct device
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few
typos in my original version of this patch.

Patrick McHardy 5b54814022 net: use symbolic values for ndo_start_xmit() return codes
Convert magic values 1 and -1 to NETDEV_TX_BUSY and NETDEV_TX_LOCKED respectively.

0 (NETDEV_TX_OK) is not changed to keep the noise down, except in very few cases
where its in direct proximity to one of the other values.
