Restructure a bit for multiple version control systems support.
Use a hash for each supported VCS that contains the commands
and patterns used to find commits, logs, and signers.--git command line options are still used for hg except for
--git-since. Use --hg-since instead.The number of commits can differ for git and hg, so --rolestats
might be different.Style changes: Use common push style push(@foo...), simplify a return
Bumped version to 0.23.

Fix email matching without name --n and --git-blame
Using --non and --git-blame caused maintainer signature
matching to fail. Fixed that by adding 3rd argument to
sub format_email to control show/hide name portion of address
Slurp -f file instead of reading line-by-line for K: pattern matching.
Suggested by Wolfram Sang as more efficient
Refactor git command execution
Break into 2 functions, execute/analyze
Share code between --git and --git-blame
Don't warn multiple times when git isn't installed
Improve stats reporting
--git-min-percent and -- rolestats now count the total number of commits
for either the period of --git-since or if using --git-blame the commits
used by the current file and calculate commit % as
# of commits signed / total commits * 100

--roles shows the role of each email address, i.e. why it was selected.
--rolestats selects --roles and adds git log/blame signers #'s and %Multiple roles are possible (supporter, maintainer, git-signer...)
--roles or --rolestats is meant to help identify appropriate maintainers
to notify and should not be used with "git send-email --cc-cmd"Example output:

The next commit will require the use of MODULE_SYMBOL_PREFIX in
.tmp_exports-asm.S. Currently it is mixed in with C structure
definitions in "asm/module.h". Move the definition of this arch option
into Kconfig, so it can be easily accessed by any code.This also lets modpost.c use the same definition. Previously modpost
relied on a hardcoded list of architectures in mk_elfconfig.c.A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs,
showed the generated code was unchanged. vmlinux was identical save
for build ids, and an apparently randomized suffix on a single "__key"
symbol in the kallsyms data).Signed-off-by: Alan Jenkins

With dynamic function tracer, by default, _mcount is defined as an
"empty" function, it returns directly without any more action. When
enabling it in user-space, it will jump to a real tracing
function(ftrace_caller), and do the real job for us.Differ from the static function tracer, dynamic function tracer provides
two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the
tracing of some indicated kernel functions(set_ftrace_filter).In the kernel version, there is only one "_mcount" string for every
kernel function, so, we just need to match this one in mcount_regex of
scripts/recordmcount.pl.For more information please look at code and Documentation/trace folder.
Steven ACK that scripts/recordmcount.pl part.

This patch fixes a bug when incrementing/decrementing on a BCD formatted
integer (i.e. 0x09++ should be 0x10 not 0x0A). It just adds a function
for incrementing/decrementing BCD integers by converting to decimal,
doing the increment/decrement and then converting back to BCD.Signed-off-by: Nathaniel McCallum

The current code to generate usb modaliases from usb_device_id assumes
that the device's bcdDevice descriptor will actually be in BCD format.
While this should be a sane assumption, some devices don't follow spec
and just use plain old hex. This causes drivers for these devices to
generate invalid modalias lines which will never actually match for the
hardware.The following patch adds hex support for bcdDevice in file2alias.c by
detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and
adjusts the output to hex format accordingly.Drivers for devices which have bcdDevice conforming to BCD will have no
change in modalias output. Drivers for devices which don't conform
(i.e. ibmcam) should now generate valid modaliases.EXAMPLE OUTPUT (ibmcam; space added to highlight change)

The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the
need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook
style comments that used to live with 'TRACE_EVENT()' are now
moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook
system understand the new 'DEFINE_EVENT()' macro. In addition
I've tried to futureproof the patch, by also adding support for
'DEFINE_SINGLE_EVENT()', since there has been discussion about
renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().Without this patch the tracepoint docbook fails to build.
I've verified that this patch correctly builds the tracepoint
docbook which currently covers signals, and irqs.Changes in v2:

If the user has an older version of objcopy, that can not handle
converting local symbols to global and vice versa, then some
functions will not be part of the dynamic function tracer. The current
code in recordmcount.pl will print a warning in this case. Unfortunately,
there exists lots of files that may have this issue with older objcopys
and this will cause a warning for every file compiled with this
issue.This patch solves this overwhelming output by creating a
.tmp_quiet_recordmcount file on the first instance the warning is
encountered. The warning will not print if this file exists.The temp file is deleted at the beginning of the compile to ensure that
the warning will happen once again on new compiles (because the issue
is still present).Reported-by: Andrew Morton
