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
./scripts lk defaults to override script

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.

Keyword matching uses K: patterns from MAINTAINERS, so if looking for the

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

Since boot_delay can't grow more than 10,000 changing it to 'int *'

Robin Holt tried to boot a 16TB system and found af_unix was overflowing
a 32bit value :
<quote>
We were seeing a failure which prevented boot. The kernel was incapable
of creating either a named pipe or unix domain socket. This comes down
to a common kernel function called unix_create1() which does:
atomic_inc(&unix_nr_socks);
if (atomic_read(&unix_nr_socks) > 2 * get_max_files())
goto out;
The function get_max_files() is a simple return of files_stat.max_files.
files_stat.max_files is a signed integer and is computed in
fs/file_table.c's files_init().
n = (mempages * (PAGE_SIZE / 1024)) / 10;
files_stat.max_files = n;
In our case, mempages (total_ram_pages) is approx 3,758,096,384
(0xe0000000). That leaves max_files at approximately 1,503,238,553.
This causes 2 * get_max_files() to integer overflow.
</quote>
Fix is to let /proc/sys/fs/file-nr & /proc/sys/fs/file-max use long
integers, and change af_unix to use an atomic_long_t instead of atomic_t.
get_max_files() is changed to return an unsigned long. get_nr_files() is
changed to return a long.
unix_nr_socks is changed from atomic_t to atomic_long_t, while not
strictly needed to address Robin problem.
Before patch (on a 64bit kernel) :
# echo 2147483648 >/proc/sys/fs/file-max
# cat /proc/sys/fs/file-max
-18446744071562067968
After patch:
# echo 2147483648 >/proc/sys/fs/file-max
# cat /proc/sys/fs/file-max
2147483648
# cat /proc/sys/fs/file-nr

Our Moorestown platform has two max7315 chips which is covered by pca953x
i2c gpio driver.
A while ago this driver got updated with nested irq thread support, and it
broke the compatibity with "request_irq". For example, the gpio_keys.c
driver can not work with this driver now. This patch fixes the issue by
switching to generic_handle_irq.
Also fix the irq_base issue: irq_base == 0 is valid, and a "-1" value
should mean invalid. IRQ 0 is not a valid IRQ, irq_base of 0 is valid.
