While fstr_real_len is only being used under if (encrypted),
gcc-6 still warns.
Fixes this false positive:
fs/ubifs/dir.c: In function 'ubifs_readdir':
fs/ubifs/dir.c:629:13: warning: 'fstr_real_len' may be used
uninitialized in this function [-Wmaybe-uninitialized]
fstr.len = fstr_real_len
Initialize fstr_real_len to make gcc happy.

We have a couple of inline assemblies like memchr() and strlen() that
read from memory, but tell the compiler only they need the addresses
of the strings they access.
This allows the compiler to omit the initialization of such strings
and therefore generate broken code. Add the missing memory barrier to
all string related inline assemblies to fix this potential issue. It
looks like the compiler currently does not generate broken code due to
these bugs.

The qsi inline assembly takes an initialized "cc" variable as output
operand but specifies it as write-to operand only instead of
read/write operand. This allows the compiler to omit the
initialization, which in fact it also does (gcc 6.1).
Use the "+" constraint modifier to fix this. In addition also use the
Q constraint to specify the hws_qsi_info_block memory location, so the
compiler can generate slightly better code. Also get rid of the cc
clobber since none of the instructions within the inline assembly
modify the condition code.

This patch introduces tracepoint definitions and tracepoint
event invocations for the s390 zcrypt device.
Currently there are just two tracepoint events defined.
An s390_zcrypt_req request event occurs as soon as the
request is recognized by the zcrypt ioctl function. This
event may act as some kind of request-processing-starts-now
indication.
As late as possible within the zcrypt ioctl function there
occurs the s390_zcrypt_rep event which may act as the point
in time where the request has been processed by the kernel
and the result is about to be transferred back to userspace.
The glue which binds together request and reply event is the
ptr parameter, which is the local buffer address where the
request from userspace has been stored by the ioctl function.
The main purpose of this zcrypt tracepoint patch is to get
some data for performance measurements together with
information about the kind of request and on which card and
queue the request has been processed. It is not an ffdc
interface as there is already code in the zcrypt device
driver to serve the s390 debug feature interface.

Rework the debug feature calls and initialization. There
are now two debug feature entries used by the zcrypt code.
The first is 'ap' with all the AP bus related stuff and the
second is 'zcrypt' with all the zcrypt and devices and
driver related entries. However, there isn't much traffic on
both debug features. The ap bus code emits only some debug
info and for zcrypt devices on appearance and disappearance
there is an entry written.
The new dbf invocations use the sprintf buffer layout,
whereas the old implementation used the ascii dbf buffer.
There are now 5*8=40 bytes used for each entry, resulting in
5 parameters per call. As the sprintf buffer needs a format
string the first parameter provides this and so up to 4 more
parameters can be used. Alltogehter the new layout should be
much more human readable for customers and test.

Add defines and switch case code to handle the two invalid
domain response codes better. Until now these two response
codes are handled via default resulting in -EAGAIN and
switching the processed queue to offline. So this kind of
malformed request bounced through all suitable queues and
switched them off. Now this kind of malformed request is
just rejected with EINVAL without switching off the queue.

According to the system architecture the current implementation
requires the presence of the N bit in GR2 in the TAPQ response
field to validate the max. number of domains (Nd).
Older machine types don't have this N bit, hence the max. domain
field was ignored.
Before the N bit was introduced the maximum number of domain was
a constant value of 15. So set this value in case of N bit absence.

For the older CEX2x and CEX3x cards the function bits returned
by TAPQ do not reflect the functions of the card. Instead the
functionality is implicit by the type of the card. The reworked
zcrypt requires to have the function bits set correct, so this
patch fixes this. The queue selection is not only based on these
function bits but also on function pointers set by the individual
drivers.

Currently the ap infrastructure only supports one domain at a time.
This feature extends the generic cryptographic device driver to
support multiple cryptographic domains simultaneously.
There are now card and queue devices on the AP bus with independent
card and queue drivers. The new /sys layout is as follows:
/sys/bus/ap
devices
<xx>.<yyyy> -> ../../../devices/ap/card<xx>/<xx>.<yyyy>
...
card<xx> -> ../../../devices/ap/card<xx>
...
drivers
<drv>card
card<xx> -> ../../../../devices/ap/card<xx>
<drv>queue
<xx>.<yyyy> -> ../../../../devices/ap/card<xx>/<xx>.<yyyy>
...
/sys/devices/ap
card<xx>
<xx>.<yyyy>
driver -> ../../../../bus/ap/drivers/<zzz>queue
...
driver -> ../../../bus/ap/drivers/<drv>card
...
The two digit <xx> field is the card number, the four digit <yyyy>
field is the queue number and <drv> is the name of the device driver,
e.g. "cex4".
For compatability /sys/bus/ap/card<xx> for the old layout has to exist,
including the attributes that used to reside there.

Martin Schwidefsky.

Crypto requests are very different in complexity and thus runtime.
Also various crypto adapters are differ with regard to the execution
time. Crypto requests can be balanced much better when the request
type and eligible crypto adapters are rated in a more precise

dedicated requests will be introduced.

The poll thread of the AP bus is burning CPU while waiting for

While stressing memory and IO at the same time we changed SMT settings,
we were able to consistently trigger deadlocks in the mm system, which
froze the entire machine.
I think that under memory stress conditions, the large allocations
performed by blk_mq_init_rq_map may trigger a reclaim, which stalls
waiting on the block layer remmaping completion, thus deadlocking the
system. The trace below was collected after the machine stalled,
waiting for the hotplug event completion.
The simplest fix for this is to make allocations in this path
non-reclaimable, with GFP_NOIO. With this patch, We couldn't hit the
issue anymore.
This should apply on top of Jens's for-next branch cleanly.
Changes since v1:
- Use GFP_NOIO instead of GFP_NOWAIT.

This is due to the fact that skcipher_done_slow() may be entered with

case where walk->buffer == walk->page, it appears to be the intention
that walk->buffer point to walk->page after skcipher_next_slow(), so
ensure that is the case.

In function public_key_verify_signature(), returns variable ret on
error paths. When the call to kmalloc() fails, the value of ret is 0,
and it is not set to an errno before returning. This patch fixes the
bug.

Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.
There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

The build system stopped generating ikconfig.h in v2.6.8. Remove an entry
for it in dontdiff. There's also a reference to it in a small comment.
Remove that comment too, as it is of little help in any case.
