Joe Perches 6ef1c52e12 scripts/get_maintainer.pl: use case insensitive name de-duplication
Case insensitive name and email address matching can help reduce
duplication when authors don't always use the exact same signature.

o Add a --interactive per-file exact_match hash so git history
  can be checked on per-file only when there is no direct maintainer
o Make @interactive_to list global so save_commits_by_<foo> can check
  email names & addresses against this list for duplication
o Don't allow --interactive and --sections
o rename subroutine get_maintainer to get_maintainers
o Added help text option to --interactive menu prompt

Update version to 0.26-beta4

Florian Mickler dace8e300d scripts/get_maintainer.pl: add interactive mode
This is a first version of an interactive mode for
scripts/get_maintainer.pl.

It allows the user to interact with the script.  Each cc candidate can be
selected and deselected and a shortlog of authored commits can be
displayed for each candidate.

The menu is displayed via STDERR, the end result is outputted to STDOUT.
This unusual mechanism allows using get_maintainer.pl in interactive mode
via git send-email --cc-cmd.

Sure.

Add a search path for the .conf file.

3 paths are added:

.             customized per-tree configurations
$HOME         user global configuration when per-tree configs don't exist

Joe Perches e3e9d11479 scripts/get_maintainer.pl: add default --git-fallback, remove default --git
Adding commit signers when there is a listed MAINTAINER for a file
can make the output list longer than necessary.

Change the --git default from on to off.

Add a new --git-fallback option (default on) used to add commit signers
only when there is no MAINTAINER for a file.

git history is used when --git-fallback is enabled and the pattern
directory depth is not the same as the file directory depth.

For instance:

X86 ARCHITECTURE (32-BIT AND 64-BIT)
M:	Thomas Gleixner <tglx@linutronix.de>
M:	Ingo Molnar <mingo@redhat.com>
M:	"H. Peter Anvin" <hpa@zytor.com>
M:	x86@kernel.org
T:	git git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git
S:	Maintained
F:	Documentation/x86/
F:	arch/x86/

If using "./scripts/get_maintainer -f arch/x86/lib/atomic64_32.c", the pattern
for "arch/x86/" does not match the directory depth of "arch/x86/lib"
so the MAINTAINERS entries and git history is used to produce:

$ ./scripts/get_maintainer.pl -f --rolestats arch/x86/lib/atomic64_32.c
Thomas Gleixner <tglx@linutronix.de> (maintainer:X86 ARCHITECTURE...)
Ingo Molnar <mingo@redhat.com> (maintainer:X86 ARCHITECTURE...)
"H. Peter Anvin" <hpa@zytor.com> (maintainer:X86 ARCHITECTURE...,commit_signer:1/1=100%)
x86@kernel.org (maintainer:X86 ARCHITECTURE...)
Luca Barbieri <luca@luca-barbieri.com> (commit_signer:1/1=100%)
linux-kernel@vger.kernel.org (open list)

Luca Barbieri is added because he signed the only commit to
arch/x86/lib/atomic64_32.c during the last year and he meets the
other default qualifications.
	--git-min-percent (default:10)
	--git-min-signatures (default:1)

If current users of ./scripts/get_maintainers.pl have scripts
that use --nogit that expect git history to be excluded, those
scripts should be updated to include --nogit-fallback or a
.get_maintainer.conf file should be created with --nogit-fallback.

Joe Perches 63ab52db5b scripts/get_maintainer.pl: Add --git-blame --rolestats "Authored lines" information
When options --git-blame and --rolestats are specified, add
the maintainers with the qualifying --git-min-percent amount
of lines authored of the complete file.  Does not add more
authors than specified by --git-max-maintainers.

For anyone using hg, this option works but is _very_ slow.
It's orders of magnitude slower than git slow.

The get_maintainer.pl version was incremented to 0.25.

This can be used with or without --git.

Steven Rostedt d7b4d6de57 ftrace: Remove recursion between recordmcount and scripts/mod/empty
When DYNAMIC_FTRACE is enabled and we use the C version of recordmcount,
all objects are run through the recordmcount program to create a
separate section that stores all the callers of mcount.

The build process has a special file: scripts/mod/empty.o. This is
built from empty.c which is literally an empty file (except for a
single comment). This file is used to find information about the target
elf format, like endianness and word size.

The problem comes up when we need to build recordmcount. The
build process requires that empty.o is built first. The build rules
for empty.o will try to execute recordmcount on the empty.o file.
We get an error that recordmcount does not exist.

To avoid this recursion, the build file will skip running recordmcount
if the file that it is building is script/mod/empty.o.

Steven Rostedt 85caa993d7 ftrace: Use objtree for C version of recordmcount
The C version of recordmcount is compiled to a binary, which will
end up located in the objtree. If the kernel is built with O=path,
the srctree will not include the binary recordmcount caller.

Steven Rostedt 4447586364 ftrace: Do not process kernel/trace/ftrace.o with C recordmcount program
The file kernel/trace/ftrace.c references the mcount() call to
convert the mcount() callers to nops. But because it references
mcount(), the mcount() address is placed in the relocation table.

The C version of recordmcount reads the relocation table of all
object files, and it will add all references to mcount to the
__mcount_loc table that is used to find the places that call mcount()
and change the call to a nop. When recordmcount finds the mcount reference
in kernel/trace/ftrace.o, it saves that location even though the code
is not a call, but references mcount as data.

On boot up, when all calls are converted to nops, the code has a safety
check to determine what op code it is actually replacing before it
replaces it. If that op code at the address does not match, then
a warning is printed and the function tracer is disabled.

The reference to mcount in ftrace.c, causes this warning to trigger,
since the reference is not a call to mcount(). The ftrace.c file is
not compiled with the -pg flag, so no calls to mcount() should be
expected.

This patch simply makes recordmcount.c skip the kernel/trace/ftrace.c
file. This was the same solution used by the perl version of
recordmcount.

Steven Rostedt c28d5077f8 ftrace: Remove duplicate code for 64 and 32 bit in recordmcount.c
The elf reader for recordmcount.c had duplicate functions for both
32 bit and 64 bit elf handling. This was due to the need of using
the 32 and 64 bit elf structures.

This patch consolidates the two by using macros to define the 32
and 64 bit names in a recordmcount.h file, and then by just defining
a RECORD_MCOUNT_64 macro and including recordmcount.h twice we
create the funtions for both the 32 bit version as well as the
64 bit version using one code source.

that's not read here.)

Ingo Molnar d6dad199a1 jump label: Fix GCC feature check when distcc is used
The following build bug occurs on distcc builds:

   CC      arch/x86/kernel/asm-offsets.s
 In file included from include/linux/module.h:24,
                  from include/linux/crypto.h:22,

 include/trace/events/module.h:18: error: expected '(' before 'goto'
 include/trace/events/module.h:18: error: expected identifier or '*' before '(' token

It triggers because distcc is invoked by turning $CC into "distcc gcc",
but gcc-goto.sh check script was using $1 not $@ to expand parameters.

base patch to implement 'jump labeling'. Based on a new 'asm goto' inline
assembly gcc mechanism, we can now branch to labels from an 'asm goto'
statment. This allows us to create a 'no-op' fastpath, which can subsequently
be patched with a jump to the slowpath code. This is useful for code which
might be rarely used, but which we'd like to be able to call, if needed.
Tracepoints are the current usecase that these are being implemented for.

Junio C Hamano 8c41e5e363 kconfig: fix menuconfig on debian lenny
In 60f33b8 (kconfig: get rid of stray a.o, support ncursesw, 2006-01-15),
support to link menuconfig with ncursesw library was added.  To compute
the linker command option -l, we check "libncursesw.{so,a,dylib}" to allow
ncursesw to be used as a replacement ncurses.  However, when checking what
header file to include, we do not check /usr/include/ncursesw directory.

Add /usr/include/ncursesw to the list of directories that are checked.
With this patch, on my Debian Lenny box with libncursesw5-dev package but
not libncurses5-dev package, I can say "make menuconfig".

Nicolas Palix afc48a82fa Coccinelle: Add iterators/itnull.cocci
Many iterators have the property that the first argument is always bound
to a real list element, never NULL.  False positives arise for some
iterators that do not have this property, or in cases when the loop
cursor is reassigned.  The latter should only happen when the matched
code is on the way to a loop exit (break, goto, or return).

Find missing unlocks.  This semantic match considers the specific case
where the unlock is missing from an if branch, and there is a lock
before the if and an unlock after the if.  False positives are due to
cases where the if branch represents a case where the function is
supposed to exit with the lock held, or where there is some preceding
function call that releases the lock.

Fix this by checking if the kernel source tree is the root of the git or
hg repository. No fix for svn: If the kernel source is not tracked in
the svn repository, it works as expected, otherwise determining the
'repository root' is not really a defined task.

Arnaud Lacombe 7080e47bb2 kbuild: don't include `check-lxdialog' ldflags in global HOST_LOADLIBES
On BSD systems, `check-lxdialog' would select -lcurses as the default
curses library which would conflict with -lncurses at runtime: curses'
compatible symbols are getting handled by the system's curses library while the
ncurses-specific symbols are getting handled by the ports' ncurses.

This fixes `nconf' segmentation fault on these systems.

Nir Tzachar a72f3e2b82 nconfig: add search support
Remove the old hotkeys feature, and replace it by an interactive string
search.
From nconfig help:

Searching: pressing '/' triggers interactive search mode.
           nconfig performs a case insensitive search for the string
           in the menu prompts (no regex support).
           Pressing the up/down keys highlights the previous/next
           matching item. Backspace removes one character from the
           match string. Pressing either '/' again or ESC exits
           search mode. All other keys behave normally.

Miscellaneous other changes (including Rundy's and Justin's input).
