qeth: don't query for info if hardware not ready.
When qeth device is queried for ethtool data, hardware operation
is performed to extract the necessary information from the card.
If the card is not online at the moment (e.g. it is undergoing
recovery), this operation produces undesired effects like
temporarily freezing the system. This patch prevents execution
of the hardware query operation when the card is not online.
In such case, ioctl() operation returns error with errno ENODEV.

Because of the embedded qdio_buffer array struct qeth_qdio_out_q is
quite large resulting in an order 4 allocation. This is likely to

s390: improve debug feature usage
The maximum usable buffer size of the s390 debug feature (when using
the sprintf_view) is 11 * sizeof(long) (1 pointer for the format
string + 10 arguments). When a larger buffer size is specified the
additional memory is unused and wasted per debug entry. So reducing
the buffer size to its maximum (or to the actual buffer size used)
will make more precious debug feature space usable.
For pci_msg, chsc_msg, and cio_crw we use the additional usable dbf
space to reduce the number of allocated pages.

qeth: change default standard blkt settings for OSA
blkt settings (or LAN idle settings) for an OSA Express card
determine when and how often an OSA Express card tells the
operating system about new incoming packets. The semantic of
these settings has changed starting with OSA Express3. Currently
the qeth standard settings apply to OSA Express2 and older
generations of OSA Express cards, while new generations of OSA
Express cards require extra coding of their reasonable default.
To cover future OSA Express generations the qeth default standard
blkt setting is now the desired setting for OSA generations
starting with OSA Express3, while the fixed set of older OSA
Express cards receives its blkt settings explicitly.

qeth: Support VEPA mode
The existing port isolation mode 'forward' will now verify that the adjacent
switch port supports the required reflective relay (RR) mode. This patch adds
the required error handling for the cases where enabling port isolation mode
'forward' can now fail.
Furthermore, once established, we never fall back from one of the port
isolation modes to a non-isolated mode without further user-interaction.
This includes cases where the isolation mode was enabled successfully, but
ceases to work e.g. due to configuration changes at the switch port.
Finally, configuring an isolation mode with the device being offline
will make onlining the device fail permanently upon errors encountered until
either errors are resolved or the isolation mode is changed by the user to a
different mode.

qeth: Fix IPA_CMD_QIPASSIST return code handling
Return codes of IPA_CMD_QIPASSIST are not checked, especially the ones which

would not enable all available features on older card generations.
This patch adds proper checking and sets the bare minimum in the supported

s390/sysinfo,stsi: change return code handling
Change return code handling of the stsi() function:
In case function code 0 was specified the return value is the
current configuration level (already shifted). That way all
the code that actually copied the stsi_0() function can go
away.
Otherwise the return value is 0 (success) or negative to
indicate an error (currently only -EOPNOTSUPP).
Also stsi() is no longer an inline function. The function is
not performance critical, but every caller would generate an
exception table entry for this function.

Also unify the IBM copyright statement. We did have a lot of sightly

people start to take the old/"wrong" statements to use as a template
for new files.
So unify all of them in one go.

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

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

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

Tejun Heo <tj@kernel.org> |
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.

qeth: no recovery after layer mismatch (z/VM NICs)
Depending on their definition in z/VM, virtual devices for z/VM
VSWITCH or GuestLAN must be configured either in layer2 or in
layer3 mode. If qeth detects a layer mismatch, device activation
fails. Trying to recover from this error cannot help; thus
scheduling a recovery should be avoided.
In addition, since recovery is forbidden during online setting of
a qeth device, existence of its network device is guaranteed for all
dev_close() calls in qeth. The corresponding checks can be removed.

qeth: Prepare-function to call s390dbf was wrong
Prepare-function to call s390dbf was wrong handling variable arguments.
This worked as macro but not as function any more.
Now using va_list processing.

ccwgroup_create_from_string() and handle parsing inside the ccwgroup

qeth: set lan_online flag after a received STARTLAN
Problem: A STARTLAN command from the adapter may arrive while a
qeth recovery is currently running with a failed qeth
STARTLAN. Usually qeth schedules a recovery when
receiving a STARTLAN command from the adapter. But
another recovery scheduled while a recovery is already
running never starts. Thus the qeth-administered
lan_online flag remains zero in this scenario, even
though the adapter-STARTLAN has happened.
Solution: Set lan_online flag for a received STARTLAN from the
adapter in case scheduled recovery does not start.
