Andy Whitcroft 8c6a98b22b Input: sysrq - ensure sysrq_enabled and __sysrq_enabled are consistent
Currently sysrq_enabled and __sysrq_enabled are initialised separately
and inconsistently, leading to sysrq being actually enabled by reported
as not enabled in sysfs.  The first change to the sysfs configurable
synchronises these two:

    static int __read_mostly sysrq_enabled = 1;
    static int __sysrq_enabled;

Add a common define to carry the default for these preventing them becoming
out of sync again.  Default this to 1 to mirror previous behaviour.

Marc Kleine-Budde 3a5655a5b5 can: at91_can: make can_id of mailbox 0 configurable
Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the contents of mailbox
0 may be send under certain conditions (even if disabled or in rx mode).

The workaround in the errata suggests not to use the mailbox and load it
with an unused identifier.

This patch implements the second part of the workaround. A sysfs entry
"mb0_id" is introduced. While the interface is down it can be used to
configure the can_id of mailbox 0. The default value id 0x7ff.

In order to use an extended can_id add the CAN_EFF_FLAG (0x80000000U)
to the can_id. Example:

- standard id 0x7ff:
echo 0x7ff      > /sys/class/net/can0/mb0_id

- extended id 0x1fffffff:
echo 0x9fffffff > /sys/class/net/can0/mb0_id

Marc Kleine-Budde 0909c1ec6f can: at91_can: clean up usage of AT91_MB_RX_FIRST and AT91_MB_RX_NUM
This patch cleans up the usage of two macros which specify the mailbox
usage. AT91_MB_RX_FIRST and AT91_MB_RX_NUM define the first and the
number of RX mailboxes. The current driver uses these variables in an
unclean way; assuming that AT91_MB_RX_FIRST is 0;

This patch cleans up the usage of these macros, no longer assuming
AT91_MB_RX_FIRST == 0.

Yong Zhang 3ff6dcac73 sched: Fix poor interactivity on UP systems due to group scheduler nice tune bug
Michael Witten and Christian Kujau reported that the autogroup
scheduling feature hurts interactivity on their UP systems.

It turns out that this is an older bug in the group scheduling code,
and the wider appeal provided by the autogroup feature exposed it
more prominently.

When on UP with FAIR_GROUP_SCHED enabled, tune shares
only affect tg->shares, but is not reflected in
tg->se->load. The reason is that update_cfs_shares()
does nothing on UP.

So introduce update_cfs_shares() for UP && FAIR_GROUP_SCHED.

This issue was found when enable autogroup scheduling was enabled,
but it is an older bug that also exists on cgroup.cpu on UP.

Rob Landley f1d0c99865 Make CIFS mount work in a container.
Teach cifs about network namespaces, so mounting uses adresses/routing
visible from the container rather than from init context.

A container is a chroot on steroids that changes more than just the root
filesystem the new processes see.  One thing containers can isolate is
"network namespaces", meaning each container can have its own set of
ethernet interfaces, each with its own own IP address and routing to the
outside world.  And if you open a socket in _userspace_ from processes
within such a container, this works fine.

But sockets opened from within the kernel still use a single global
networking context in a lot of places, meaning the new socket's address
and routing are correct for PID 1 on the host, but are _not_ what
userspace processes in the container get to use.

So when you mount a network filesystem from within in a container, the
mount code in the CIFS driver uses the host's networking context and not
the container's networking context, so it gets the wrong address, uses
the wrong routing, and may even try to go out an interface that the
container can't even access...  Bad stuff.

This patch copies the mount process's network context into the CIFS
structure that stores the rest of the server information for that mount
point, and changes the socket open code to use the saved network context
instead of the global network context.  I.E. "when you attempt to use
these addresses, do so relative to THIS set of network interfaces and
routing rules, not the old global context from back before we supported
containers".

The big long HOWTO sets up a test environment on the assumption you've
never used ocntainers before.  It basically says:

1) configure and build a new kernel that has container support
2) build a new root filesystem that includes the userspace container
control package (LXC)
3) package/run them under KVM (so you don't have to mess up your host
system in order to play with containers).
4) set up some containers under the KVM system
5) set up contradictory routing in the KVM system and the container so
that the host and the container see different things for the same address
6) try to mount a CIFS share from both contexts so you can both force it
to work and force it to fail.

For a long drawn out test reproduction sequence, see:

Rusty Russell 7ef88ad561 BUILD_BUG_ON: make it handle more cases
BUILD_BUG_ON used to use the optimizer to do code elimination or fail
at link time; it was changed to first the size of a negative array (a
nicer compile time error), then (in
8c87df457c) to a bitfield.

This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON();
as Jan points out in that commit, it didn't work as intended anyway.

bitfields: needs a literal constant at parse time, and can't be put under
	"if (__builtin_constant_p(x))" for example.
negative array: can handle anything, but if the compiler can't tell it's
	a constant, silently has no effect.
link time: breaks link if the compiler can't determine the value, but the
	linker output is not usually as informative as a compiler error.

If we use the negative-array-size method *and* the link time trick,
we get the ability to use BUILD_BUG_ON() under __builtin_constant_p()
branches, and maximal ability for the compiler to detect errors at
build time.

We also document it thoroughly.

Dmitry Torokhov e94965ed5b module: show version information for built-in modules in sysfs
Currently only drivers that are built as modules have their versions
shown in /sys/module/<module_name>/version, but this information might
also be useful for built-in drivers as well. This especially important
for drivers that do not define any parameters - such drivers, if
built-in, are completely invisible from userspace.

This patch changes MODULE_VERSION() macro so that in case when we are
compiling built-in module, version information is stored in a separate
section. Kernel then uses this data to create 'version' sysfs attribute
in the same fashion it creates attributes for module parameters.

Jesper Juhl 3f391c79b0 CIFS: Remove pointless variable assignment in cifs_dfs_do_automount()
In fs/cifs/cifs_dfs_ref.c::cifs_dfs_do_automount() we have this code:

	...
	mnt = ERR_PTR(-EINVAL);
	if (IS_ERR(tlink)) {
		mnt = ERR_CAST(tlink);
		goto free_full_path;
	}
	ses = tlink_tcon(tlink)->ses;

	rc = get_dfs_path(xid, ses, full_path + 1, cifs_sb->local_nls,
		&num_referrals, &referrals,
		cifs_sb->mnt_cifs_flags & CIFS_MOUNT_MAP_SPECIAL_CHR);

	cifs_put_tlink(tlink);

	mnt = ERR_PTR(-ENOENT);
	...

The assignment of 'mnt = ERR_PTR(-EINVAL);' is completely pointless. If we
take the 'if (IS_ERR(tlink))' branch we'll set 'mnt' again and we'll also
do so if we do not take the branch. There is no way we'll ever use 'mnt'
with the assigned 'ERR_PTR(-EINVAL)' value, so we may as well just remove
the pointless assignment.

the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior,
it would simply disable the integrated GPU. So we adjust our PCI class

In such a configuration, the IGFX is not a primary VGA controller and

Geert Uytterhoeven f9b07897c6 m68k: Uninline strchr()
Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.

If strchr() is defined as an inline function, this causes linking errors
like

	ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined!

As m68k is the only architecture that has an inline strchr() and this
inline version is not an optimized asm version, uninline strchr() and use
the standard out-of-line C version in lib/string.c instead.

This also decreases the defconfig/allmodconfig kernel image sizes by a few
hundred bytes.

Jesper Juhl 233d84c46c ALSA: Xonar, CS43xx: Don't overrun static array
'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of
8. So, this code in sound/pci/oxygen/xonar_cs43xx.c::dump_d1_registers()

    		for (i = 2; i <= 8; ++i)
	  			snd_iprintf(buffer, " %02x", data->cs4398_regs[i]);

will overrun the array when 'i == 8'.

I guess that what's needed to fix it is the trivial patch below, but I
must admit that I have no idea about this code, so I may very well be
wrong. Additionally, I have no way to actually test this, so all I know is
that the below compiles. Someone who actually knows this code should take
a look before anything is comitted - consider the below (not much more
than) a bug report.

Kurt Van Dijck 0a0b7a5f7a can: add driver for Softing card
This patch adds the driver that creates a platform:softing device
from a pcmcia_device
Note: the Kconfig indicates a dependency on the softing.ko driver,
but this is purely to make configuration intuitive. This driver will
work independent, but no CAN network devices appear until softing.ko is
loaded too.
