If a weak function is used as a relocation reference for mcount callers
and that function is overridden, it will cause ftrace to fail at run time.The current code should prevent a weak function from being used, but if
one is, the code should exit with an error to fail at compile time.Signed-off-by: Li Hong

Add a variable to contain the regex needed to find weak functions
in the 'nm' output. This will allow other archs to easily override it.Also rename the regex variable $nm_regex to $local_regex to be more
descriptive.Signed-off-by: Li Hong

Move the mcount section check to the beginning of the objdump read loop.
This makes the code easier to follow since the search for the mcount
section is performed first before the mcount callers are processed.Signed-off-by: Li Hong

The current logic to check objcopy's version is incorrect. This patch
fixes the algorithm and disables the use of local functions as a reference
if the objcopy version does not support static to global conversions.Also remove some usused variables.

The ftrace.c file may reference the mcount function and this may interfere
with the recordmcount.pl processing. To avoid this, the code does not
process the kernel/trace/ftrace.o. But currently the check is against
a relative path. This patch modifies the check to succeed if the path
is an absolute path.Signed-off-by: Li Hong

The documentation currently says we will use the first function in a section
as a reference. The actual algorithm is: choose the first global function we
meet as a reference. If there is none, choose the first local one.
Change the documentation to be consistent with the code.Also add several other clarifications.

Based on the commit:
a586df06 "x86: Support __attribute__((__cold__)) in gcc 4.3"
some of the functions goes to the ".text.unlikely" section.
Looks like there's not many of them (I found printk, panic,
__ssb_dma_not_implemented, fat_fs_error), but still worth to
include I think.Signed-off-by: Jiri Olsa

The Makefile.lib will call "echo -ne" to append uncompressed kernel size to
bzip2/lzma kernel image.
The "echo" here depends on the shell that /bin/sh pointing to.
On Ubuntu system, the /bin/sh is pointing to dash, which does not support
"echo -e" at all. Use /bin/echo instead of shell echo should always be safe.Signed-off-by: Alek Du

The binrpm-pkg target (binary RPM only) fails when called with
KBUILD_OUTPUT set. This patch makes it work.For the rpm-pkg target (source + binary RPM), building with
KBUILD_OUTPUT set is not possible and also not needed as the
actual build is done in a temporary directory anyway, so check
that KBUILD_OUTPUT is not set in that case to avoid later errors.Signed-off-by: Frans Pop

This makes it consistent with other buses (platform, i2c, vio, ...). I'm
not sure why we use the prefixes, but there must be a reason.This was easy enough to do it, and I did it.

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like
we do with I2C drivers.This is useful when a single driver supports several variants of devices
but it is not possible to detect them in run-time (like non-JEDEC chips
probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is
overkill.This patch also makes life a lot easier on OpenFirmware platforms, since
with OF we extensively use proper device IDs in modaliases.Signed-off-by: Anton Vorontsov

Commit b478b782e110fdb4135caa3062b6d687e989d994 "kallsyms, tracing: output
more proper symbol name" introduces a "bugfix" that introduces a segfault
in kallsyms in my configurations.The cause is the introduction of prefix_underscores_count() which attempts
to count underscores, even in symbols that do not have them. As a result,
it just uselessly runs past the end of the buffer until it crashes:CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1
KSYM .tmp_kallsyms1.S
/bin/sh: line 1: 16934 Done sh-linux-gnu-nm -n .tmp_vmlinux1
16935 Segmentation fault | scripts/kallsyms > .tmp_kallsyms1.S
make: *** [.tmp_kallsyms1.S] Error 139This simplifies the logic and just does a straightforward count.

Previous behavior was "bottom-up" in each section from the pattern "F:"
entry that matched. Now information is entered into the various lists in
the "as entered" order for each matched section.This also allows the F: entry to be put anywhere in a section, not just as
the last entries in the section.And a couple of improvements:
Don't alphabetically sort before outputting the matched scm, status,
subsystem and web sections.Ignore content after a single email address so these entries are acceptable

Before this change, matched sections were added in the order
of appearance in the normally alphabetic section order of

Julia Lawall suggested that get_maintainers.pl should have the
ability to include signatories of commits that are modified by
a particular patch.Vegard Nossum did something similar once.
http://lkml.org/lkml/2008/5/29/449The modified script looks the commits for all lines in the
patch, and includes the "-by:" signatories for those commits.
It uses the same git-min-percent, git-max-maintainers, and
git-min-signatures options. git-since is ignored.It can be used independently from the --git default, so
./scripts/get_maintainers.pl --nogit --git-blame
or
./scripts/get_maintainers.pl --nogit --git-blame -f
is acceptable.If used with -f , all lines/commits for the file are
checked.--git-blame can be slow if used with -f
