Make firmware/dsp56k/bootstrap.asm buildable on a56, the free Motorola
DSP56001 assembler (http://www.zdomain.com/a56.html).

Summary of changes:

  - Remove '<' and '>' candy (they specify explicit addressing modes,
    which a56 don't grok, but uses implicitly anyway).

  - Replace 'move' with 'movem' when accessing program memory.

  - Rename a few labels to avoid duplicates (which a56 can't handle).

proc_ipcauto_dointvec_minmax() is the only user of ipc_auto_callback(),
since the former function is protected by CONFIG_PROC_FS, so should be the

Introduce a new kernel parameter `coredump_filter'.  Setting a value to
this parameter causes the default bitmask of coredump_filter to be
changed.

It is useful for users to change coredump_filter settings for the whole
system at boot time.  Without this parameter, users have to change
coredump_filter settings for each /proc/<pid>/ in an initializing script.

POSIX requires the si_pid to be the process id of the sender, so ->si_pid
should really be set to 'tgid'.  This change does have following changes
in behavior:

	- When sending pdeath_signal on re-parent to a sub-thread, ->si_pid
	  cannot be used to identify the thread that did the re-parent since
	  it will now show the tgid instead of thread id.

	- A multi-threaded application that expects to find the specific
	  thread that encountered a SIGPIPE using the ->si_pid will now
	  break.

The code to draw penguin logos always uses some properties of the main logo.
This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different
types than the main logo, which causes corrupted logo images.

  http://bugzilla.kernel.org/show_bug.cgi?id=12181

Hence skip additional logos that are not compatible with the main logo.

Technically, it's possible to draw multiple logos of different types on
truecolor displays, but this would complicate the (already quite
complicated) logo drawing code even more.

Provide a static debounce configuration mechanism for twl4030 GPIOs,
replacing the previous dynamic one.  The single user of that mechanism was
for MMC card detect debouncing.

Boards can provide a bitmask saying which GPIOs to debounce (30 msec).
It's always enabled for pins with the MMC card-detect/VMMCx link active,
so most boards won't need to set the debounce mask.

This is a net code shrink, including runtime footprint.
