d4977c78e9 checkpatch: warn on declaration with storage class not at the beginning
The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

3354957a4f checkpatch: add check for too short Kconfig descriptions
I've seen various new Kconfigs with rather unhelpful one liner
descriptions.  Add a Kconfig warning for a minimum length of the Kconfig
help section.

Right now I arbitarily chose 4. The exact value can be debated.

0fa0559900 scripts/get_maintainer.pl: default to not include unspecified tags
This changes the default of the option --git-all-signature-types to be
disabled by default.

The effect being, that only certain (currently Signed-Off-By:, Acked-by:
and Reviewed-By:) tags are used to get adresses of potential maintainers.

Motivated is this change by the desire to not 'spam' people unnecessary: A
Tested-By or a Reported-By is not ment as a hint that those people want
to/are able to review patches to the code in question.

In a quest to find resilient statistics for this i came up with this:

I produced a list of all the tag-signers not already covered with a
signed-off/acked/reviewed tag somewhere in the last year of git history.

Those were 650 addresses of "assumed non-developers".

And to check if those "assumed non-developers" are professional
testers/reporters worth cc'ing, i then counted their total appearences
in the git log:

469 were mentioned only once.
123 were mentioned twice.
38 three times
8 four times
5 six times
5 five times
1 eight times
1 fourteen times

I believe this supports my thesis, that the ''non-maintainer-tags'' are
not actively useful for patch-review.  (except probably the guy mentioned
fourteen times...)

But of course one could also find arguments to poke holes in this
statistics, for example does this statistic not include code-locality: A
tested-by on a patch that touches some specific piece of code can be more
worth than a signed-off in another part of the tree.

But...  let's play it safe and let's err on the "safe" side meaning to not
spam those people when in doubt.  We already have the signed-off's and
Maintainers file.  So this should be ok.  And if need be, the maintainers
can always forward the patch.

[i probably could make a diploma thesis out of this changelog :)]

.get_maintainer.conf can contain any valid command-line argument.

File contents are prepended to any additional command line arguments.

e4d26b027a scripts/get_maintainer.pl: optionally ignore non-maintainer signatures
When using --git to determine who to send a patch to, get_maintainers will
currently include all signatures.  This can include signers that simply
report an issue or test a patch.  Signers that use this tag are not
necessarily good candidates to review new patches.

This patch allows get_maintainers to optionally restrict output to only
signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:.

Signed-off-by: is included because those are people who are responsible
for the code.

Acked-by: is questionable, but as signers that use this tag tend to be
active linux gatekeepers, false positives are tolerable.

Reviewed-by: is included because signers responsible for the code thought
that the review feedback for a changeset by that signer was valuable.

This patch has been modified from Florian's original submission to change
the supported signature types to the canonical forms and use slightly
different spacing.  A couple of spacing issues were also corrected in the
original source.  The command line argument was also renamed.

1704f47b50 lockdep: Add novalidate class for dev->mutex conversion
The conversion of device->sem to device->mutex resulted in lockdep
warnings. Create a novalidate class for now until the driver folks
come up with separate classes. That way we have at least the basic
mutex debugging coverage.

Add a checkpatch error so the usage is reserved for device->mutex.

The patch below works fine (at least with Debian). It needs your first
patch that moves the definitions to mod_devicetable.h. Verified that
aliases for these modules are generated correctly:

drivers/media/radio/radio-sf16fmi.c
drivers/net/ne.c
drivers/net/3c515.c
drivers/net/smc-ultra.c
drivers/pcmcia/i82365.c
drivers/scsi/aha1542.c
drivers/scsi/aha152x.c
drivers/scsi/sym53c416.c
drivers/scsi/g_NCR5380.c

Tested with RTL8019AS (ne), AVA-1505AE (aha152x) and dtc436e (g_NCR5380)
cards - they now work automatically.

Generate pnp:d aliases for isapnp_device_tables. This allows udev to load
these modules automatically.

d61931d89b x86: Add optimized popcnt variants
Add support for the hardware version of the Hamming weight function,
popcnt, present in CPUs which advertize it under CPUID, Function
0x0000_0001_ECX[23]. On CPUs which don't support it, we fallback to the
default lib/hweight.c sw versions.

A synthetic benchmark comparing popcnt with __sw_hweight64 showed almost
a 3x speedup on a F10h machine.

enough for us -- we need the driver loaded _immediately_ because otherwise
the NIC driver may just abort and then the phy 'device' goes away.

4c98ecaf35 scripts/kernel-doc: fix empty function description section
scripts/kernel-doc mishandles a function that has a multi-line function
short description and no function parameters.  The observed problem was
from drivers/scsi/scsi_netlink.c:

/**
 * scsi_netlink_init - Called by SCSI subsystem to intialize
 * 	the SCSI transport netlink interface
 *
 **/

kernel-doc treated the " * " line as a Description: section with only a
newline character in the Description contents.  This caused
output_highlight() to complain: "output_highlight got called with no
args?", plus produce a perl call stack backtrace.

The fix is just to ignore Description sections if they only contain "\n".

22fd2d3e4f checkpatch.pl: add union and struct to the exceptions list
Here is a small code snippet, which will be complained about by
checkpatch.pl:

#define __STRUCT_KFIFO_COMMON(recsize, ptrtype) \
	union { \
		struct { \
			unsigned int	in; \
			unsigned int	out; \
		}; \
		char		rectype[recsize]; \
		ptrtype		*ptr; \
		const ptrtype	*ptr_const; \
	};

This construct is legal and safe, so checkpatch.pl should accept this.  It
should be also true for struct defined in a macro.

Add the `struct' and `union' keywords to the exceptions list of the
checkpatch.pl script, to prevent error message "Macros with multiple
statements should be enclosed in a do - while loop".  Otherwise it is not
possible to build a struct or union with a macro.

42bdf74c95 checkpatch: trivial fix for trailing statements check
In case if the statement and the conditional are in one line, the line
appears in the report doubly.

And items of this check have no blank line before the next item.

This patch fixes these trivial problems, to improve readability of the
report.

[sample.c]
  > if (cond1
  >        && cond2
  >        && cond3) func_foo();
  >
  > if (cond4) func_bar();

Before:

3c840c18bc scripts/get_maintainer.pl: fix possible infinite loop
If MAINTAINERS section entries are misformatted, it was possible to have
an infinite loop.

Correct the defect by always moving the index to the end of section + 1

Also, exit check for exclude as soon as possible.

22dd5b0cba get_maintainer: fix perlcritic warnings
perlcritic is a standard checker for Perl Best Practices.  This patch
fixes most of the warnings in the get_maintainer script.  If kernel

as well...

03372dbbe6 scripts/get_maintainer.pl: add --file-emails, find embedded email addresses
Add an imperfect option to search a source file for email addresses.

New option:  --file-emails or --fe

email addresses in files are freeform text and are nearly impossible to
parse.  Still, might as well try to do a somewhat acceptable job of
finding them.  This code should find all addresses that are in the form
addr@domain.tld

The code assumes that up to 3 alphabetic words along with dashes, commas,
and periods that preceed the email address are a name.

If 3 words are found for the name, and one of the first two words are a
single letter and period, or just a single letter then the 3 words are use
as name otherwise the last 2 words are used.

Some variants that are shown correctly:
    John Smith <jksmith@domain.org>
    Random J. Developer <rjd@tld.com>
    Random J. Developer (rjd@tld.com)
    J. Random Developer rjd@tld.com

Variants that are shown nominally correctly:
    Written by First Last (funny-addr@somecompany.com)
is shown as:
    First Last <funny-addr@somecompany.com>

Variants that are shown incorrectly:
    Some Really Long Name <srln@foo.bar>
    MontaVista Software, Inc. <source@mvista.com>
are returned as:
    Long Name <srln@foo.bar>
    "Software, Inc" <source@mvista.com>

--roles and --rolestats show "(in file)" for matches.

For instance:

Without -file-emails:

$ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
linux-kernel@vger.kernel.org (open list)

With -fe:

$ ./scripts/get_maintainer.pl -f -fe -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
Matt Mackall <mpm@selenic.com> (in file)
Ingo Molnar <mingo@redhat.com> (in file)
linux-kernel@vger.kernel.org (open list)
netdev@vger.kernel.org (open list:NETWORKING [GENERAL])

The number of email addresses in the file in not limited.  Neither is the
number of returned email addresses.

1c32fd0c5a kernel-doc: drop the -filelist option, it doesn't work
I also found the -filelist option, but apparently the implementation
is broken, and it was broken from the very first git commit.
For the -filelist option I suggest the removal (I wasn't able to find
any users of it, moreover it's not even listed in the
usage() output, so presumably nobody knows about it).

a9e7314b79 kernel-doc: track line numbers for each file separately
The problem is that $. keeps track of the current record number (which
is line number by default). But if you pass it multiple files, it does
not wrap at the end of file, and therefore contains the *total* number
of processed lines.
I suppose we can fix line numbering by introducing a simple assignment
$. = 1
before processing every new file.
