Andy Whitcroft 13214adf73 update checkpatch.pl to version 0.14
This version brings the remainder of the queued fixes.  A number of fixes
for items missed reported by Andrew Morton and others.  Also a handful
of new checks and fixes for false positives.  Of note:

 - new warning associated with --file to try and avoid cleanup only patches,
 - corrected handling of completly empty files,
 - corrected report handling with multiple files,
 - handling of possible types in the face of multiple declarations,
 - detection of unnessary braces on complex if statements (where present), and
 - all new comment spacing handling.

Andy Whitcroft c2fdda0dfb update checkpatch.pl to version 0.13
This version brings a large number of fixes which have built up over
the Christmas period.  Mostly these are fixes for false positives, both
through improvments to unary checks and possible type detection.  It
also brings new checks for while location and CVS keywords.  Of note:

  - a number of fixes to unary detection
  - detection of a number of new forms of types to improve type matching
  - better inline handling
  - recognision of '%' as an operator

Andy Whitcroft (28):
      Version: 0.13
      unary detection: maintain bracket state across lines
      move to pre-sanitising the entire file
      the text of a #error statement should be treated like it is in quotes
      line sanitisation needs to target double backslash correctly
      tighten comment guestimation for lines starting ' * '
      debug: add a debug framework
      prevent unclosed single quotes from spreading
      add % as an operator
      the text of a #warning statement should be treated like it is in quotes
      possible matching applies in typedefs
      single statement block checks must not trigger when two or more statements
      possible types: local variables may also be const
      treat inline as a type attribute to even when out of place
      possible types: sparse annotations are valid indicators
      possible types: beef up the possible type testing
      check for hanging while statements on the wrong line
      utf8 checks need to occur against the raw lines
      function brace checks should use any whitespece matches
      comments should take up space in the line when sanitised
      remove debugging from if assignment checks
      possible types -- ensure we detect all pointer casts
      fix tests for function spacing in the presence of #define
      clean up the UTF-8 error message to be clearer
      test-lib: invert the status report, output success counts
      detect and report CVS keywords
      tests: break out tests
      Add $Id$ to the CVS keyword checks

Benny Halevy (1):
      checkpatch.pl: recognize the #elif preprocessor directive

Geert Uytterhoeven (1):

Paulo Marques f2df3f65d0 kallsyms should prefer non weak symbols
When resolving symbol names from addresses with aliased symbol names,
kallsyms_lookup always returns the first symbol, even if it is a weak
symbol.

This patch changes this by sorting the symbols with the weak symbols last
before feeding them to the kernel.  This way the kernel runtime isn't
changed at all, only the kallsyms build system is changed.

Another side effect is that the symbols get sorted by address, too.  So,
even if future binutils version have some bug in "nm" that makes it fail to
correctly sort symbols by address, the kernel won't be affected by this.

Mathieu says:

  I created a module in LTTng that uses kallsyms to get the symbol
  corresponding to a specific system call address.  Unfortunately, all the
  unimplemented syscalls were all referring to the (same) weak symbol
  identifying an unrelated system call rather that sys_ni (or whatever
  non-weak symbol would be expected).  Kallsyms was dumbly returning the first
  symbol that matched.

  This patch makes sure kallsyms returns the non-weak symbol when there is
  one, which seems to be the expected result.

Robin Getz a3b81113fb remove support for un-needed _extratext section
When passing a zero address to kallsyms_lookup(), the kernel thought it was
a valid kernel address, even if it is not.  This is because is_ksym_addr()
called is_kernel_extratext() and checked against labels that don't exist on
many archs (which default as zero).  Since PPC was the only kernel which
defines _extra_text, (in 2005), and no longer needs it, this patch removes
_extra_text support.

Sam Ravnborg 603d49885e kconfig: ignore select of unknown symbol
We have had warnings for a long time about select of unknow symbol
but the warnings does not really makes sense since we may
select a symbol that is relevant and defined in one
arch but not in another arch.
And as long as we do not use a common set of Kconfig files
for all archs lets just ignore this case.

Previously we have used this to find bad uses of
select but we need a more relaible method to do so.

Greg Kroah-Hartman de6f92b9ee USB: handle idVendor of 0x0000
Some crazy devices in the wild have a vendor id of 0x0000.  If we try to
add a module alias with this id, we just can't do it due to a check in
the file2alias.c file.  Change the test to verify that both the vendor
and product ids are 0x0000 to show a real "blank" module alias.

Note, the module-init-tools package also needs to be changed to properly
generate the depmod tables.

Sam Ravnborg e241a63037 kbuild: warn about ld added unique sections
If there is a mixture of specifying sections for code in gcc
and assembler then if the assembler code do not add
the "ax" flags the linker will see this as two different sections
and generate unique sections for each. ld does so by adding a dot
and a number.
Teach modpost to warn if a section shows up that match this
pattern - but do this only for non-debug sections.

It will result in warnings like this:

WARNING: vmlinux.o (.sched.text.1): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.

All warnings seen with a defconfig build for:
x86 (32+64bit) and sparc64 has been fixed (via respective maintainers).

arm, powerpc (64 bit), s390 (32 bit), ia64, alpha, sh4 checked - no
warnings seen with a defconfig build.

Sam Ravnborg 588ccd732b kbuild: add verbose option to Section mismatch reporting in modpost
If the config option CONFIG_SECTION_MISMATCH is not set and
we see a Section mismatch present the following to the user:

modpost: Found 1 section mismatch(es).
To see additional details select "Enable full Section mismatch analysis"
in the Kernel Hacking menu (CONFIG_SECTION_MISMATCH).

If the option CONFIG_SECTION_MISMATCH is selected
then be verbose in the Section mismatch reporting from mdopost.
Sample outputs:

WARNING: o-x86_64/vmlinux.o(.text+0x7396): Section mismatch in reference from the function discover_ebda() to the variable .init.data:ebda_addr
The function  discover_ebda() references
the variable __initdata ebda_addr.
This is often because discover_ebda lacks a __initdata
annotation or the annotation of ebda_addr is wrong.

WARNING: o-x86_64/vmlinux.o(.data+0x74d58): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()
The variable pci_serial_quirks references
the function __devexit pci_plx9050_exit()
If the reference is valid then annotate the
variable with __exit* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

Sam Ravnborg eb8f689046 Use separate sections for __dev/__cpu/__mem code/data
Introducing separate sections for __dev* (HOTPLUG),
__cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG)
allows us to do a much more reliable Section mismatch
check in modpost. We are no longer dependent on the actual
configuration of for example HOTPLUG.

This has the effect that all users see much more
Section mismatch warnings than before because they
were almost all hidden when HOTPLUG was enabled.
The advantage of this is that when building a piece
of code then it is much more likely that the Section
mismatch errors are spotted and the warnings will be
felt less random of nature.

Change the logic in modpost so we identify all the

Compared to the previous approach we are much less

positives low.

The implmentation is changed to use a table based
lookup and we now check all combinations in first
pass so we no longer need separate passes for init
and exit sections.

an allyesconfig build without CONFIG_HOTPLUG.

Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.

This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

* Do not include <sys/wait.h> and <signal.h> (comes from times when
  lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.

Andres Salomon 2f4b489b77 kconfig: use getopt() in conf.c for handling command line arguments
Switch from doing our own parsing of command line arguments to
using getopt(3) to do it.  Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).

Note some subtle changes:
 - The argument '-?' is no longer supported.
 - '-h' is not treated as an error, so output goes to stdout, and we
   exit with '0'.
 - There is no compatibility checking amongst arguments; the last option
   will simply override earlier options.  For example, 'conf -n -y foo'
   is perfectly valid now (input_mode will be set_yes).  Previously, that
   would have been an error ("can't find file -y").

Tejun Heo 551559e13a kbuild: implement modules.order
When multiple built-in modules (especially drivers) provide the same
capability, they're prioritized by link order specified by the order
listed in Makefile.  This implicit ordering is lost for loadable
modules.

When driver modules are loaded by udev, what comes first in
modules.alias file is selected.  However, the order in this file is
indeterministic (depends on filesystem listing order of installed
modules).  This causes confusion.

The solution is two-parted.  This patch updates kbuild such that it
generates and installs modules.order which contains the name of
modules ordered according to Makefile.  The second part is update to
depmod such that it generates output files according to this file.

Note that both obj-y and obj-m subdirs can contain modules and
ordering information between those two are lost from beginning.
Currently obj-y subdirs are put before obj-m subdirs.

Sam Ravnborg cleaned up Makefile modifications and suggested using awk
to remove duplicate lines from modules.order instead of using separate
C program.

This version brings a new terse output mode as well as many improvements to
the unary detection and bare type regcognition.  It also brings the usual
updates for false positives, though these seem to be slowing markedly
now that the unary detector is no longer just putting its finger in the
air and guessing.  Of note:

  - new --terse mode producing a single line per report
  - loosening of the block brace checks
  - new checks for enum/union/struch brace placements
  - hugely expanded "bare type" detection
  - checks for inline usage
  - better handling of already open comment blocks
  - handle patches which introduce or remove lines without newlines

  # make {allno,allyes,allmod,rand}config [ARCH=...]
  option \ host arch      | 32bit         | 64bit
  =====================================================
  ./.                     | 32bit         | 64bit
  ARCH=x86                | 32bit         | 32bit
  ARCH=i386               | 32bit         | 32bit
  ARCH=x86_64             | 64bit         | 64bit

The general rule are that ARCH= and native architecture takes
precedence over the configuration.

So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says.  The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.

This behaviour is consistent with previous behaviour so no
suprises here.

make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

Sam Ravnborg daa93fab82 x86: enable "make ARCH=x86"
After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".

With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
   => select 64-bit

Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.

Sam Ravnborg 2a113281f5 kconfig: use $K64BIT to set 64BIT with all*config targets
The variable K64BIT can now be used to select the
value of CONFIG_64BIT.

This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n

To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.

Linus Torvalds e8b8c97773 Revert "kconfig: tristate choices with mixed tristate and boolean values"
This reverts commit a5bf3d891a.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:

  "That Kconfig hasn't changed (other than adding new drivers), and it's
   worked that way for several years now ...  so the issue seems to be
   changes in menuconfig/kconfig/etc semantics.

   The issue is that when USB_GADGET=m, it's no longer possible to
   configure peripheral controller drivers as modules ...  the
   controller drivers can now only be configured for static linkage.

   It should be making a choice of one of the controller drivers which
   could work on the target system, and allow that driver to be linked
   either as a module (ok iff USB_GADGET=m) or statically."

Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

Trent Piepho 4b21960f90 kbuild: modpost problem when symbols move from one module to another
When part of build an external module tree, modpost first reads in the
kernel's and then the external tree's Module.symvers files.  From these files
it establishes a symbol => module mapping.  When it later reads in each module
built and processes the symbols it finds, it discovers the symbol=>module
mapping from Module.symvers and leaves it as it is.

The problem comes with a module has been re-named or a symbol has moved from
one module to another, since the Module.symvers file was generated.  modpost
does not update the symbol=>module mapping when it finds the new location of
the symbol when scanning the newly built modules.  This results in the module
containing incorrect dependency information and the new Module.symvers file
written by modpost will also contain the incorrect mappings, perpetuating the
problem to the next build, and so on.

When building the out of kernel development tree for kernel subsystem, like
v4l-dvb or ALSA, deleting the external Module.symvers file before building
(which the kernel build system doesn't do and shouldn't be necessary anyway),
won't fix the problem.  modpost still reads the kernel's Module.symvers, and
since we a building a kernel subsystem, it will define the same symbols as the
external modules.

Randy Dunlap 6b5b55f6c4 kernel-doc: fix doc blocks and html
Johannes Berg reports (Thanks!) that &struct names are not highlighted in
html output format when they are inside a DOC: block.

DOC: blocks were not escaped thru xml_escape() like other kernel-doc
comments were.  Fixed that.

However, that left a problem with <p> ($blankline_html) being processed
thru xml_escape(), converting it to &lt;p&gt;, which isn't good for the
generated html output (the <p> should remain unchanged), so this patch also
introduces the notion of "local" kernel-doc meta-characters
('\\\\mnemonic:'), which are converted to html just before writing the
stream to its output file.

Please report any problems that you (anyone) see in "highlighting" in any
output mode (text, man, html, xml).

The rationale behind this change is to introduce support for

As a replacement for the uglier:
ifeq ($(CONFIG_WHATEVER_DEBUG),y)

Sam Ravnborg 0c53c8e6eb kbuild: check for wrong use of CFLAGS
External modules have in a few cases modifed gcc option
by modifying CFLAGS. This has never been documented and
was a bad practice.
With the check to use KBUILD_CFLAGS it will no longer work
so we better error out and tell what was wrong as a service
to the external module users.

This check can be overruled if
KBUILD_NOPEDANTIC is set to something.
Addid this possibility may allow older external
module to build without any code modifications but potentially
only loosing some un-important gcc options.

CFG80211)

This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.

The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.

Change kconfig behavior so that mixing bool and tristate config settings in

Milton Miller 0b35786d77 kbuild: call make once for all targets when O=.. is used
Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.

When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree).  Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.

I did not try to address make -j for mixed dot-config and no-dot-config
targets.  Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.

Currently scripts/ver_linux prints "Binutils" or other random

When I initially submitted a patch to correct that, I was not aware
that the output from "ld -v" could differ as much as it turned out
it can, so my original fix turned out to not cover all bases.
This patch works correctly with all the different "ld -v" output
that people posted in replys to my first patch, so it should be a
clear win over what we have currently.

I've written a script which tries do this efficiently, in case all other

this is done to exclude macros like MMCONFIG_).

Undefined Kconfig variables should be not be removed without care, but for
instance arch/i386/boot/ uses a bunch of undefined Kconfig vars:

$ scripts/checkunknowndefines.sh arch/i386/boot/
arch/i386/boot/video.h uses undefined symbol VIDEO_400_HACK

Pavel Emelyanov 4665079cbb [NETNS]: Move some code into __init section when CONFIG_NET_NS=n
With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.

Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.

The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

Sam Ravnborg cb7e51d8b1 kbuild: fix modpost warnings for xtensa
The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.

The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0

Sam Ravnborg 83cda2bb37 kbuild: be more foregiving on init section naming
In the whitelist function of modpost now use the same
check to identify init_section as in other places of modpost.
This has the effect that we now recognize sections named
.init.text.19 as init sections and we no longer warn
when we see these.

At the same time make surrounding code readable by dropping
use of temporary flags.

Tejun Heo 9281acea6a kallsyms: make KSYM_NAME_LEN include space for trailing '\0'
KSYM_NAME_LEN is peculiar in that it does not include the space for the
trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating
buffer.  This is nonsense and error-prone.  Moreover, when the caller
forgets that it's very likely to subtly bite back by corrupting the stack
because the last position of the buffer is always cleared to zero.

This patch increments KSYM_NAME_LEN by one and updates code accordingly.

* off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro
  is fixed.

* Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together,
  MODULE_NAME_LEN was treated as if it didn't include space for the
  trailing '\0'.  Fix it.

Roman Zippel d8982ba1f2 kconfig: reset generated values only if Kconfig and .config agree.
Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).

The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.

The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.

David Woodhouse 0db19c412c x86_64: fix headers_install
A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
postfix.  So the second and later asm files #included in the same C file
(often through standard headers like ioctl.h) yields no symbols.

Strangeness with the Ubuntu 'tell me if I support something that's not
explcitly mentioned in POSIX, and I'll strip it out' shell, I believe.

We don't need the 'export' but we do need a semicolon at the end of the
FNAME line:

David Woodhouse edd5cd4a94 Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM
Not all the world is an i386.  Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer.  Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.

Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely.  In fact, ARM already had that, but called it
sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
the needed compatibility routine.  And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.

Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

Sam Ravnborg 2648a53acf kbuild: fix sh64 section mismatch problems
There's a special .cranges section that is almost always generated,
with data being moved to the appropriate section by the linker at a later
stage.

To give a bit of background, sh64 has both a native SHmedia instruction
set (32-bit instructions) and SHcompact (which is compatability with
normal SH -- 16-bit, a massively reduced register set, etc.). code ranges
are emitted when we're using the 32-bit ABI, but not the 64-bit one.

It is a special staging section used solely by binutils where code with
different flags get placed (more specifically differing flags for input
and output sections), before being lazily merged by the linker.

The closest I've been able to find to documentation is:
  http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src

It's an array of 8-byte Elf32_CRange structure given in
  http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src
that describes for which ISA a range is used.

Silence the warnings by allowing references from .init.text to .cranges.

The following warnings are fixed:

To avoid hardcoding a lot of function names in modpost introduce
a marker so relevant function/data can be marked.
When modpost see a reference to a init/exit function from
a function/data marked no warning will be issued.

Sylvain Munaut d1ab423502 powerpc: Fix the MODALIAS generation in modpost for of devices
Since the devices may have multiple (or none) compatible properties,
the uevent generated internally by the kernel may have multiple
"C..." entries. So the MODALIAS stored in the module must have
wilcard before and after the compatible entry.
Also, if the 'compatible' field is not used for matching, there
will be no 'C' and that must handled as well.

The previous code handled all those case incorrectly and it
"mostly" worked ... but not always.

Borislav Petkov 884f2810b1 kernel-doc: handle arrays with arithmetic expressions as initializers
In a different approach here's a patch that handles the special case of
composite arithmetic expressions in array size initializers.  With it,
prior to pushing the split strings on the @first_arg array, I split the
keywords before the array name as before and then keep the array name along
with the subscript expression as a single whole element which gets pushed
last.  In this manner, kernel-doc produces correct output without removing
whitespaces which makes the array subscripts unreadable in the docs.

Yasunori Goto 72280ede31 Add white list into modpost.c for memory hotplug code and ia64's machvec section
This patch is add white list into modpost.c for some functions and
ia64's section to fix section mismatchs.

  sparse_index_alloc() and zone_wait_table_init() calls bootmem allocator
  at boot time, and kmalloc/vmalloc at hotplug time. If config
  memory hotplug is on, there are references of bootmem allocater(init text)
  from them (normal text). This is cause of section mismatch.

  Bootmem is called by many functions and it must be
  used only at boot time. I think __init of them should keep for
  section mismatch check. So, I would like to register sparse_index_alloc()
  and zone_wait_table_init() into white list.

  In addition, ia64's .machvec section is function table of some platform
  dependent code. It is mixture of .init.text and normal text. These
  reference of __init functions are valid too.

Bryan Wu 1394f03221 blackfin architecture
This adds support for the Analog Devices Blackfin processor architecture, and
currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561
(Dual Core) devices, with a variety of development platforms including those
avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP,
BF561-EZKIT), and Bluetechnix!  Tinyboards.

The Blackfin architecture was jointly developed by Intel and Analog Devices
Inc.  (ADI) as the Micro Signal Architecture (MSA) core and introduced it in
December of 2000.  Since then ADI has put this core into its Blackfin
processor family of devices.  The Blackfin core has the advantages of a clean,
orthogonal,RISC-like microprocessor instruction set.  It combines a dual-MAC
(Multiply/Accumulate), state-of-the-art signal processing engine and
single-instruction, multiple-data (SIMD) multimedia capabilities into a single
instruction-set architecture.

The Blackfin architecture, including the instruction set, is described by the
ADSP-BF53x/BF56x Blackfin Processor Programming Reference
http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf

The Blackfin processor is already supported by major releases of gcc, and
there are binary and source rpms/tarballs for many architectures at:
http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete
documentation, including "getting started" guides available at:
http://docs.blackfin.uclinux.org/ which provides links to the sources and
patches you will need in order to set up a cross-compiling environment for
bfin-linux-uclibc

This patch, as well as the other patches (toolchain, distribution,
uClibc) are actively supported by Analog Devices Inc, at:
http://blackfin.uclinux.org/

We have tested this on LTP, and our test plan (including pass/fails) can
be found at:
http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel

Michael Ellerman eda890af79 kbuild: propagate errors from find in scripts/gen_initramfs_list.sh
If the find(1) in scripts/gen_initramfs_list.sh generates any errors, it
will cause gen_initramfs_list.sh to fail (because of "set -e"), however
the errors from find are not printed to the user. This is rather confusing:

~/src/powerpc$ make O=~/build/powerpc-cell32/
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
make[1]: *** [usr] Error 2
make[1]: *** Waiting for unfinished jobs....
make[1]: *** wait: No child processes.  Stop.
make: *** [_all] Error 2

It is much easier to work out what the problem is if we let the errors
from find hit the console, eg:

~/src/powerpc$ make O=~/build/powerpc-cell32/
find: /home/michael/initramfs-source/home: Permission denied
find: /home/michael/initramfs-source/lost+found: Permission denied

dies with an error, that ccache doesn't support the argument -A.

This patch adds some quoting such that it works again for me.

This script cleans up various classes of stealth whitespace.  In

- Whitespace (spaces or tabs)before newline;
- DOS line endings (CR before LF);
- Space before tab (spaces are deleted or converted to tabs);
- Empty lines at end of file.
