This splits the mmu_context handling between 32-bit hash based

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.)

Given this list (contains three gpio specifiers, one of which is a hole):
gpios = <&phandle1 1 2 3
0 /* a hole */
&phandle2 4 5 6>;
of_parse_phandles_with_args() would report -ENOENT for the `hole'
specifier item, the same error value is used to report the end of the
list, for example.
Sometimes we want to differentiate holes from real errors -- for
example when we want to count all the [syntax correct] specifiers.
With this patch of_parse_phandles_with_args() will report -EEXITS when
somebody requested to parse a hole.
Also, make the out_{node,args} arguments optional, when counting we
don't really need the out values.

Make the driver report an ENXIO error immediately upon NAK instead of
waiting for another interrupt and getting a timeout.
When reading from a device that is not present or declines to respond
to, e.g., a non-existent register address, CPM immediately reports a
NAK condition in the TxBD, but the driver kept waiting until a timeout,
which takes 1 second and causes an ugly console error message.

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'

The pktcdvd created class devices only export some sysfs files,
but have no char dev_t registered in the driver.
At class device creation time they copy the dev_t value of the
block device to the char device, wich will register a new char
device in the driver core and userspace, with a conflicting dev_t
value.
In many cases the class devices dev_t just points to a random
USB device. This fixes the sysfs "duplicate entry" errors.
