uname -m was leaving a newline in $arch, and not passing the tests.
Also, printing the unknown arch on failure is probably helpful.

Currently, checkstack.pl only looks for fixed subtractions from the stack
pointer. However, things like this:
void function(int size)
{
char stackbuster[size << 2];
...
are certainly worth pointing out, I think.
This could perhaps be done more cleanly, and the following patch only
adds "dynamic" REs for x86 and x86_64, but it works:
0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax)
0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax)
0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax)
0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax)
...
(Inspired by Keith Owens' old stack-check script)

Add checks for the question mark colon operator spacing, and also check
the other uses of colon. Colon means a number of things:
- it introduces the else part of the ?: operator,
- it terminates a goto label,
- it terminates the case value,
- it separates the identifier from the bit size on bit fields, and
- it is used to introduce option types in asm().

Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.
There also seems to be noone willing to bring this port back into a usable
state.
This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

When a kernel was rebuilt, the previous Module.markers was not cleared.
It caused markers with different format strings to appear as duplicates
when a markers was changed. This problem is present since
scripts/mod/modpost.c started to generate Module.markers, commit
b2e3e658b344c6bcfb8fb694100ab2f2b5b2edb0
It therefore applies to 2.6.25, 2.6.26 and linux-next.

For 'make modules_install', install any firmware required by
the modules which are being installed.
Also add a 'make firmware_install' target which doesn't depend on the
configuration, but installs _all_ available in-kernel-tree firmware into

for distributors to make arch-independent (and config-independent)

We have a case in powerpc in which we want to link some library
routines with all module objects. The routines are intended for
handling out-of-line function call register save/restore so having
them as EXPORT_SYMBOL() is counter productive (we do also need to
link the same "library" code into the kernel).
Without this patch a powerpc build would error out and fail
to build modules with the added register save/restore module.
There were two obvious solutions:
1) To link the .o file before the modpost stage
2) To ignore the symbols in modpost
Option 1) was ruled out because we do not have any separate
linking stage for single file modules.
This patch implements option 2 - and do so only for powerpc.
The symbols we ignore are all undefined symbols named:
_restgpr_*, _savegpr_*, _rest32gpr_*, _save32gpr_*

This version is a bit of a whopper. This version brings a few new checks,
improvements to a number of checks mostly through modifications to the
way types are parsed, several fixes to quote/comment handling, as well as
the usual slew of fixes for false positives.
Of note:
- return is not a function and is now reported,
- preprocessor directive detection is loosened to match C99 standard,
- we now intuit new type modifiers, and
- comment handling is much improved
Andy Whitcroft (18):
Version: 0.19
fix up a couple of missing newlines in reports
colon to parenthesis spacing varies on asm
values: #include is a preprocessor statement
quotes: fix single character quotes at line end
add typedef exception for the non-pointer "function types"
kerneldoc parameters must be on one line, relax line length
types: word boundary is not always required
improved #define bracketing reports
uninitialized_var is an annotation not a function name
possible types: add possible modifier handling
possible types: fastcall is a type modifier
types: unsigned is not a modifier on all types
static/external initialisation to zero should allow modifiers
checkpatch: fix recognition of preprocessor directives -- part 2
comments: fix inter-hunk comment tracking
return is not a function
do not report include/asm/foo.h use in include/linux/foo.h

kbuild: fix $(src) assignmnet with external modules
|

When we introduced support for KBUILD_EXTRA_SYMBOLS
we started to include the externam module's kbuild
file when doing the final modpost step.
As external modules often do:
ccflags-y := -I$(src)
We had problems because $(src) was unassinged and
gcc then used the next parameter for -I resulting in
strange build failures.
Fix is to assign $(src) and $(obj) when building
external modules.

We currently have a way to add special CFLAGS to code, but we do not have a
way to remove them if needed.
With the case of ftrace, some files should simply not be profiled. Adding
the -pg flag to these files is simply a waste, and adding "notrace" to each
and every function is ugly.
Currently we put in "Makefile turd" [1] to stop the compiler from adding -pg
to certain files. This was clumsy and awkward.
This patch now adds the revese of CFLAGS_(basename).o with
CFLAGS_REMOVE_(basename).o. This allows developers to prevent certain
CFLAGS from being used to compile files. For example, we can now do
CFLAGS_REMOVE_string.o = -pg
to remove the -pg option from the string.o file in the lib directory.
Note: a space delimited list of options may be added to the REMOVE macro.
