Document "patch -p1" behaviour of modern patches, and remove make dep
phase that isn't needed any more.

This patch adds the missing page_reference() macro for the no swap
case. With no rmap this is trivially a call to TestClearPageReferenced().

Add a per-architecture flat.h flat format executable header. The idea is
to support the different options required in a clean way. For starters
we need to be able to configure the initial stack layout, and this
differs for different CPU types.

This first patch adds the header for the m68knommu architecture.

This patch does a couple of things to the MMUless proc support:

1. change current->sig to current->sighand
2. initialize vsize var in task_vsize() function
3. correctly set *text and *data values in task_vsize() function

This patch removes a duplicate menu option in the m68knommu Kconfig.

This patch includes seq_file.h in the m68knommu machdep.h header.
Cleans up warnings caused by function prototypes.

This patch removes the use of the common RODATA define in the m68knommu
architecture. It cannot be used the same way for the m68knommu target.
For starters just inserting it here is syntactically wrong. All the read
only parts are grouped into a single "text" segment, and this is the root
cause of the problem. So for the m68knommu arch it makes sense to not
use the generic RODATA setup, but to list them locally.

This patch reformats the 68360 crt_ram.S file to make it consistent
with the other m68knommu assembler files, and generally to good
style standards :-)

This patch adds inline versions of init_emergency_isa_pool() and
blk_queue_bounce() for MMUless builds. This patch was originally
from Christoph Hellwig, as part of the MMUless merge.

This patch adds support into the common flat.h header to include
the architecture specific flat.h header. This is modelled on the
same scheme as the elf include header file support.

This patch adds a v850 architecture specific flat file header.
It supports the stack layout define needed by the flat format
load binfmt_flat.c (for MMUless CPU's).

This patch reformats the 68328/pilot crt_rom.S file to make it consistent
with the other m68knommu assembler files, and generally to good style
standards :-)

This patch creates a common set of vector code for the ColdFire
sub-architecture of the m68knommu architecture. The basic setup
code for all ColdFire CPU's is the same. Some more patches will
follow this that remove theis common code from each of the
ColdFire CPU configs.

This patch reformats the 68360 crt_rom.S file to make it consistent
with the other m68knommu assembler files, and generally to good
style standards :-)

This adds the missing config.c file for the m68knommu/68VZ328/ucdimm
target.

This patch initializes the m68knommu specific serial drivers (68328serial.c,
mcfserial.c and 68360serial.c) when used as consoles.

This patches fixes a serial port "hang" on the m68knommu ColdFire
serial driver. It was erroneoulsy looking for a state bit that
is never set.

Add exception table support to Makefile build list for m68knommu.

This patch to the MMUless flat loader does 2 important things:

1. Allow for architectures that do not want argv and envp on
   the initial process stack (v850 is an example of this)
2. Does some bounds checking on the zipped flat header when
   processing it.

This patch fixes the use of sighand for the m68knommu architecture.

This patch overhauls the cache support routines for the m68knommu
architecture. It removes depricated functions, and fixes those required
to operate as per Documentation/cachetlb.txt.

This patch adds exception table support for the m68knommu architecture.

Add initialization of init_sighand for m68knommu architectures.

Otherwise a if one them is partially empty, the following input section
can end up in the wrong place.

On the v850 RTE-MA1-CB-MULTI platform, these are normally intercepted by
the monitor for the use of an external debugger, but if you want to use
a linux-resident debugger, the kernel has to see them.

1) Preserve the v850 system-call-number register when handling a signal;
   otherwise system calls will not be correctly restarted afterwards
2) Correctly handle illegal insn exceptions, which need a special
   instruction to return (not reti), and save PC/PSW to a different place
2) Remove some unnecessary register saving in the trap handler
3) Consolidate various places that use the register save/restore macros
4) Eliminate some unused compile-time configuration stuff
5) A bit of whitespace and other syntactic cleanup

Removes a bunch of unnecessary nops... :-)

Previously the v850's copy_thread function didn't set the child's stack
pointer at all, with the result that it accidentally worked for vfork
(where the child has the same SP as the parent), but not for user
threads; kernel threads also accidentally worked, for a different
reason.

Various overflow problems compiling the lib/idr.c code for ppc64

Patch from William Lee Irwin III <wli@holomorphy.com>

Remove start_lazy_tlb() and end_lazy_tlb(), as they are unused.
