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

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
M: Ingo Molnar
M: "H. Peter Anvin"
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 (maintainer:X86 ARCHITECTURE...)
Ingo Molnar (maintainer:X86 ARCHITECTURE...)
"H. Peter Anvin" (maintainer:X86 ARCHITECTURE...,commit_signer:1/1=100%)
x86@kernel.org (maintainer:X86 ARCHITECTURE...)
Luca Barbieri (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

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.
For instance:
$ ./scripts/get_maintainer.pl --git-blame --nogit --rolestats -f lib/bitmap.c

…x' and 'unwind' into devel

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.[ extra comment Suggested-by: Sam Ravnborg ]

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.Reported-by: Ingo Molnar

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.Cc: John Reiser

This patch adds the support for the C version of recordmcount and
compile times show ~ 12% improvement.After verifying this works, other archs can add:
HAVE_C_MCOUNT_RECORD
in its Kconfig and it will use the C version of recordmcount
instead of the perl version.Cc:
