44a01d5ba8 [S390] s390/hvc_console: z/VM IUCV hypervisor console support
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.

368c1e3249 hvc_console: Escape magic sysrq key
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.)

1c55f18717 console ASCII glyph 1:1 mapping
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.

f75bc06e5d unicode table for cp437
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'

1e641743f0 Audit: Log TIOCSTI
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.)

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

a0e2f9f4a2 powerpc/BSR: Support multiple OF-node description of BSR
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).

d5e5491343 powerpc: udbg-based backend for hvc_console
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.

fe2d5ffc74 Fix platform drivers that crash on suspend/resume
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.

a564738c1c vt: incomplete initialization of vc_tab_stop
Problem 1 (see patch below):
  vc_tab_stop is declared as an array of 8 unsigned ints in struct
  vc_data in include/linux/console_struct.h .
  In drivers/char/vt.c only 5 of these 8 unsigned ints get initialized
  leading to unintended tabulator placement on displays with more than
  160 columns text.

Problem 2 (open):
  Upcoming displays will have more than 256 columns of text leading to
  invalid memory access in drivers/char/vt.c during tabulator
  calculations:
    if (vc->vc_tab_stop[vc->vc_x >> 5] & (1 << (vc->vc_x & 31)))
	break;

8950d89aca ACPI: remove CONFIG_ACPI_EC
Remove CONFIG_ACPI_EC.  It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".

Per section 6.5.4 of the ACPI 3.0b specification,

    OSPM must make Embedded Controller operation regions, accessed
    via the Embedded Controllers described in ECDT, available before
    executing any control method.

The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

233e70f422 saner FASYNC handling on file close
As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.

So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set.  And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.
