For 1 and 2 byte operands for xchg and cmpxchg the old and new values
get or'ed into the larger 4 byte old value before the compare and swap
instruction gets executed. This is done without using the proper byte
mask before or'ing the values.
If the caller passed in negative old or new values these got sign
extended by the caller. Which in turn means that either the old value
never matches, or, even worse, unrelated bytes would be changed in memory.
Luckily there don't seem to be any callers around yet, since that would
have resulted in the specification exception fixed in an earlies patch.

When accessing a 1 or 2 byte memory operand we cannot use the
passed address since the compare and swap instruction only works
for 4 byte aligned memory operands.
Hence we calculate an aligned address so that compare and swap works
correctly. However we don't pass the calculated address to the inline
assembly. This results in incorrect memory accesses and in a
specification exception if used on non 4 byte aligned memory operands.
Since this didn't happen until now, there don't seem to be
too many users of cmpxchg on unaligned addresses.

The cmpxchg macros and functions are a bit different than on other
architectures. In particular the macros do not store the return
value of a __cmpxchg function call in a variable before returning the
value.
This causes compile warnings that only occur on s390 like this one:
net/ipv4/af_inet.c: In function 'build_ehash_secret':
net/ipv4/af_inet.c:241:2: warning: value computed is not used [-Wunused-value]
To get rid of these warnings use the same construct that we already use
for the xchg macro, which was introduced for the same reason.

It has been a big mistage to add the capabilities attribute to the
cpus in sysfs:
First the attribute only contains the cpu capability of primary cpus,
which however is not necessarily (or better: unlikely) the type of
cpu the kernel runs on, which is typically an IFL.
In addition all information that is necessary is available in
/proc/sysinfo already. So this attribute partially duplicated
informations.
So programs should look into the sysinfo file to retrieve all
informations they are interested in.
Since with this kernel release also the powersavings cpu attributes
are removed this seems to be a good opportunity to remove another
broken interface.

If the IPL CPU is offline, currently the pcpu_delegate() function
used by smp_call_ipl_cpu() does not work because pcpu_delegate()
modifies the lowcore of the target CPU. In case of an offline
IPL CPU currently the prefix register is zero but pcpu->lowcore
still points to the old prefix page. Therefore the lowcore changes
done by pcpu_delegate() have no effect.
With this fix pcpu_delegate() now uses memcpy_absolute() and therefore
also prepares the absolute zero lowcore if the target CPU has prefix
register zero.

This patch introduces the new function memcpy_absolute() that allows to
copy memory using absolute addressing. This means that the prefix swap
does not apply when this function is used.
With this patch also all s390 kernel code that accesses absolute zero
now uses the new memcpy_absolute() function. The old and less generic
copy_to_absolute_zero() function is removed.

Currently the PSW restart handler and kexec are executed in real
mode with DAT=off. For kexec/kdump the function setup_regs() is
called that uses the per-cpu variable "crash_notes". Because
there are situations when the per-cpu implementation uses vmalloc
memory, calling setup_regs() in real mode can cause a program
check interrupt.
To fix that problem this patch changes the following:
* Ensure that diag308_reset() does not change PSW bits to real mode
* Enable DAT in __do_restart() after we switched to an online CPU
* Enable DAT in __machine_kexec() after we switched to the IPL CPU
* Call setup_regs() before we switch to real mode and call purgatory

The crashkernel size for kdump can be reduced at runtime with the

information is updated correctly.

Because of a design change for stand-alone kdump the function that
was done by the OS info init function is moved to the boot loader
code. This has two implications that are implemented by this patch:
a) The OS info init function is no longer called by the kernel
b) The diag 308 subcode 1 reset is no longer done by the kdump boot code.
This is necessary because otherwise the operation that is done now
by the boot loader would be reversed. For the normal kexec based
kdump mechansim the reset is already done by the kdump trigger code
(e.g. panic or PSW restart).

This set includes some minor fixes and improvements.
The one large patch addresses the special "nodir" mode,
which has been a long neglected proof of concept, but
with these fixes seems to be quite usable. It allows
the resource master to be assigned statically instead of
dynamically, which can improve performance if there is
little locality and most resources are shared.

Here's the big TTY/serial driver pull request for the 3.5-rc1 merge window.
Nothing major in here, just lots of incremental changes from Alan and
Jiri reworking some tty core things to behave better and to get a more
solid grasp on some of the nasty tty locking issues.
There are a few tty and serial driver updates in here as well.
All of this has been in the linux-next releases for a while with no problems.

Here's the driver core, and other driver subsystems, pull request for
the 3.5-rc1 merge window.
Outside of a few minor driver core changes, we ended up with the
following different subsystem and core changes as well, due to
interdependancies on the driver core:
- hyperv driver updates
- drivers/memory being created and some drivers moved into it
- extcon driver subsystem created out of the old Android staging switch
driver code
- dynamic debug updates
- printk rework, and /dev/kmsg changes
All of this has been tested in the linux-next releases for a few weeks
with no reported problems.

Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as well.
We deleted a staging driver, which was nice, and finally dropped the
obsolete usbfs code, which will make Al happy to never have to touch
that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were due
to us not building with CONFIG_PM disabled.)

While we generally attempt to get rid of board specific files and replace
them with device tree based descriptions, a lot of platforms have not
come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination of
DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not

new boards can be done by only providing new device trees instead.

The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of
booting using device trees, which is a great step forward for them. at91
and spear have pretty much completed this process with a huge amount of
work being put into at91. The other platforms are continuing the process.
We finally start to see the payback on this investment, as new machines
are getting supported purely by adding a .dts source file that can be
completely independent of the kernel source.

These cleanups are basically all over the place. The idea is to collect
changes with minimal impact but large number of changes so we can avoid
them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases.

I used the snowball.conf in a live demo that demonstrated how to use

Add the config that I use to test several archs. I downloaded several
cross compilers from:
http://kernel.org/pub/tools/crosstool/files/bin/x86_64/
and this config is an example to crosscompile several archs to make sure
that your changes do not break archs that you are not working on.
Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
I've been asked several times to provide more useful example configs for
ktest.pl, as the sample.conf is too complex (because it explains all
configs). This adds configs broken up by use case, and these configs are
based on actual configs that I use on a daily basis.
Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the
user and ask them if the OUTPUT_MIN_CONFIG should be used as the
starting point for make_min_config instead of MIN_CONFIG.
This is usually the case, and to allow the user to do so, which is
helpful if the user is creating different min configs based on tests,
and they know one is a superset of another test, they can set
USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting
to use the OUTPUT_MIN_CONFIG and it will just use it.
If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to
use MIN_CONFIG instead.
The default is that USE_OUTPUT_MIN_CONFIG is undefined.
