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
the MAINTAINERS file.For instance, finding the maintainer for drivers/scsi/wd7000.c
would first find "SCSI SUBSYSTEM", then "WD7000 SCSI SUBSYSTEM",
then "THE REST".before patch:

linux-kernel@vger.kernel.orgget_maintainer.pl now selects matched sections by longest pattern match.
Longest is the number of "/"s and any specific file pattern.This changes the example output order of MAINTAINERS to whatever is

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
--git-blame does not work with -fSigned-off-by: Joe Perches

Adding a reference to to x86's causes
the x86 linker script to have syntax errors, because the ALIGN and
ENTRY keywords get redefined to the assembly implementations of those.
One could fix this by adjusting the include structure, but I think any
solution based on that approach would be fragile.Currently, it is impossible when writing a header to do something
different for assembly files and linker scripts, even though there are
clearly cases where one wants them to define macros differently for
the two (ENTRY being an excellent example).
So I think the right solution here is to introduce a new preprocessor
definition, called LINKER_SCRIPT that is set along with __ASSEMBLY__
for linker scripts, and to use that to not define ALIGN and ENTRY in
linker scripts.
I suspect we'll find other uses for this mechanism in
the future.Signed-off-by: Tim Abbott

Albin Tonnerre reported:
Bash 4 filters out variables which contain a dot in them.
This happends to be the case of CPPFLAGS_vmlinux.lds.
This is rather unfortunate, as it now causes
build failures when using SHELL=/bin/bash to compile,
or when bash happens to be used by make (eg when it's /bin/sh)Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.This is also nice cleanup as we move the information out where
it is used.Notes for the different architectures touched:
arm - we use an already exported symbol
cris - we use a config symbol aleady available
[Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
Added a few variables to CPPFLAGS - they are only used by
the linker script.
[Not build tested]
powerpc - removed assignment that is not needed
[not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation

When typeahead find is enabled, using 'y', 'n' and 'm' to change the status

The tag file generated by the tags.sh script has some issue.
First:
The identifier-list miss the
DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL
special handling, which can result in a wrong tag, not to jump to the
right variable definition or function implementation.Second:
It makes no real sense to include function prototypes and external and
forward variable declarations, because jumping to a tag will sometimes
go to this and not to the real definition and implementation. The information
about the declaration is still there at the definition and implementation
place.So this patch make it lot easier to navigate through the kernel source
