I'm not sure why the read-only data section is excluded from the report,
it seems as relevant as the other data sections (b and d).I've stripped the symbols starting with __mod_ as they can have their
names dynamically generated and thus comparison between binaries is not
possible.Signed-off-by: Jean Delvare

Because the second and third arguments of memset have the same type, it
turns out to be really easy to mix them up.This bug comes up time after time, so checkpatch should really be checking
for it at patch submission time.Signed-off-by: Dave Jones

If you run checkpatch against multiple patches, and one of them has a
whitespace issue which can be helped via a script (rpt_cleaners), you will
see the same NOTE over and over for all subsequent patches. It makes it
seem like those patches also have whitespace problems when in reality,
there's only one or two bad apples.So reset rpt_cleaners back to 0 after we've issued the note so that it
only shows up near the patch with the actual problems.Signed-off-by: Mike Frysinger

1. simple_strto*() do not contain overflow checks and crufty,
libc way to indicate failure.
2. strict_strto*() also do not have overflow checks but the name and
comments pretend they do.
3. Both families have only "long long" and "long" variants,
but users want strtou8()
4. Both "simple" and "strict" prefixes are wrong:
Simple doesn't exactly say what's so simple, strict should not exist
because conversion should be strict by default.The solution is to use "k" prefix and add convertors for more types.
Enter
kstrtoull()
kstrtoll()
kstrtoul()
kstrtol()
kstrtouint()
kstrtoint()kstrtou64()
kstrtos64()
kstrtou32()
kstrtos32()
kstrtou16()
kstrtos16()
kstrtou8()
kstrtos8()Include runtime testsuite (somewhat incomplete) as well.
strict_strto*() become deprecated, stubbed to kstrto*() and
eventually will be removed altogether.Use kstrto*() in code today!
Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if
they'll be unused at runtime. This is temporarily solution,
because I don't want to hardcode list of archs where these
functions aren't needed. Current solution with sizeof() and
__alignof__ at least always works.Signed-off-by: Alexey Dobriyan

Regenerated the parser after "genksyms: Track changes to enum
constants".Signed-off-by: Michal Marek
Acked-by: Sam Ravnborg -
Enum constants can be used as array sizes; if the enum itself does not
appear in the symbol expansion, a change in the enum constant will go
unnoticed. Example patch that changes the ABI but does not change the
checksum with current genksyms:| enum e {
| E1,
| E2,
|+ E3,
| E_MAX
| };
|
| struct s {
| int a[E_MAX];
| }
|
| int f(struct s *s) { ... }
| EXPORT_SYMBOL(f)Therefore, remember the value of each enum constant and
expand each occurence to . The value is not actually
computed, but instead an expression in the form
(last explicitly assigned value) + N
is used. This avoids having to parse and semantically understand whole
of C.Note: The changes won't take effect until the lexer and parser are
rebuilt by the next patch.Signed-off-by: Michal Marek

While changing our build system over to use the headers_install target
as part of our klibc build, the following message started showing up in
our logs:make[2]: `scripts/unifdef' is up to date.
It turns out that the build blindly invokes a recursive make on this
target, which causes make to emit this message when the target is
already up to date. This isn't seen for most targets as the rest of the
build relies primarily on the default target and on PHONY targets when
invoking make recursively.Silence the above message when building unifdef as part of
headers_install by hiding it behind a new PHONY target called
"build_unifdef" that has an empty recipe.Signed-off-by: Mike Waychison

Add a 'W=1' Makefile switch which adds additional checking per build
object.The idea behind this option is targeted at developers who, in the
process of writing their code, want to do the occasionalmake W=1 [target.o]
and let gcc do more extensive code checking for them. Then, they
could eyeball the output for valid gcc warnings about various
bugs/discrepancies which are not reported during the normal build
process.For more background information and a use case, read through this

.cmd file breaks build if a .c file is replaced by .S or vice versa,
because the .cmd file containsfoo/bar.o: foo/bar.c ...

so the foo/bar.c -> foo/bar.o rule triggers even if there is no
