This patch introduces a new hypervisor console (HVC) back-end that provides
terminal access over the z/VM inter-user communication vehicle (IUCV).
The z/VM IUCV communication is independent of the regular tcp/ip network
and allows access even if there is no network connection between two
z/VM guest virtual machines.
The z/VM IUCV hypervisor console back-end helps the user to access a
z/VM guest virtual machine that lacks of network connectivity; and thus,
provides a "full-screen" terminal alternative to 3215/3270 terminal sessions.
Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of
HVC terminals using a z/VM IUCV back-end.
A recent version of the s390-tools package is required to establish a
terminal connection to a z/VM IUCV hypervisor console back-end.

The ctrl-o (^O) is a common control key used by several applications,
such as vim, but hvc_console uses ^O as the magic-sysrq key. This
commit allows users to send ^O to applications by pressing ^O twice
in succession.
To implement this, this commit introduces a check if ^O is pressed
again if the sysrq_pressed variable is already set. In this case,
clear sysrq_pressed state and flip the ^O character to the tty. (The
old behavior has always set "sysrq_pressed" if ^O has been entered,
and it has not flipped the ^O character to the tty.)

For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font. This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.
At the moment it affects all chars for which no substitution character
is defined. In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g. control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.
I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e. chars < 128.
The patch limits the mapping as it probably was meant anyway.

There is a major bug in the cp437 to unicode translation table. Char
0x7c is mapped to U+00a5 which is the Yen sign and wrong. The right
mapping is U+00a6 (broken bar).
Furthermore, a mapping for U+00b4 (a widely used character) is missing
even though easily possible.
The patch fixes these, as well as it provides a few other useful
mappings.
The changes are as follows:
0x0f (enhancement) enables a sort of currency symbol
0x27 (bug) enables a sort of acute accent which is a widely used character
0x44 (enhancement) enables a sort of icelandic capital letter eth
0x7c (major bug) corrects mapping
0xeb (enhancement) enables a sort of icelandic small letter eth
0xee (enhancement) enables a sort of math 'element of'

AUDIT_TTY records currently log all data read by processes marked for
TTY input auditing, even if the data was "pushed back" using the TIOCSTI
ioctl, not typed by the user.
This patch records all TIOCSTI calls to disambiguate the input. It
generates one audit message per character pushed back; considering
TIOCSTI is used very rarely, this simple solution is probably good
enough. (The only program I could find that uses TIOCSTI is mailx/nail
in "header editing" mode, e.g. using the ~h escape. mailx is used very
rarely, and the escapes are used even rarer.)

Impact: new feature
Problem on distro kernels: irq_desc[NR_IRQS] takes megabytes of RAM with
NR_CPUS set to large values. The goal is to be able to scale up to much
larger NR_IRQS value without impacting the (important) common case.
To solve this, we generalize irq_desc[NR_IRQS] to an (optional) array of
irq_desc pointers.
When CONFIG_SPARSE_IRQ=y is used, we use kzalloc_node to get irq_desc,
this also makes the IRQ descriptors NUMA-local (to the site that calls
request_irq()).
This gets rid of the irq_cfg[] static array on x86 as well: irq_cfg now
uses desc->chip_data for x86 to store irq_cfg.

The test to check for a new winsize runs out-of-sync with the
underlying tty. After a tty has been released and initialized again,
the winsize might differ between the tty and the hp struct. The
solution is to simply remove the check and always schedule the resize
work.

This adds support for multiple BSR nodes in the OF device tree.
Previously, the BSR driver only supported a single OF node describing
a BSR. Apparently when an LPAR is set to use "all system resources"
the BSR appears as a single node, but when it is handed out in pieces,
each 8 byte piece gets its own node. So, this keeps a list of BSR
devices instead of the array and includes all nodes.
Also, this makes the code be more inclusive of what BSR devices we
accept by only checking compatibility and not the device name property
(which might change in the future versions of BSR).

This adds a new backend for the hvc console based on the low-level
udbg callbacks. This effectively implements a working runtime console
in terms of the simple udbg primitives. This is kind of a hack -
since udbg isn't something you really want to be using routinely - but
it's really useful during bringup.
This can be used to quickly implement a userspace-usable console while
you're working on a proper driver for whatever console I/O device the
hardware has. Or, it can be used to avoid writing a full blown
tty/console driver entirely for quick-and-dirty I/O hardware that will
later be replaced by something else.

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.
Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().
Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be

It turns out that if one registers a struct platform_device, the
platform device code expects that platform_device.device->driver points
to a struct driver inside a struct platform_driver.
This is not the case with the ipmi-si, ipmi-msghandler and ibmaem
drivers, which causes the suspend/resume hook functions to jump off into
nowhere, causing a crash. Make this assumption hold true for these
three drivers.
