0bafd214e4 [PATCH] rtmutex: Modify rtmutex-tester to test the setscheduler propagation
Make test suite setscheduler calls asynchronously.  Remove the waits in the
test cases and add a new testcase to verify the correctness of the
setscheduler priority propagation.

d38b69689c Revert "kbuild: fix make -rR breakage"
This reverts commit e5c44fd88c.

Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.

Daniel says:

  "[The] reason is a recent change that made modules always shows as
   module.mod.  it breaks modprobe and probably many scripts..besides
   lsmod looking horrible

   stuff like this in modprobe.conf:
        install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
   makes modprobe fork/exec endlessly calling itself...until oom
   interrupts it"

850622dfaf [PATCH] kernel-doc: warn on malformed function docs.
When the verbose (-v) option is used with scripts/kernel-doc, this option
reports when the kernel-doc format is malformed and apparently contains
function description lines before function parameters.  In these cases, the
kernel-doc script will print something like: Warning(filemap.c:335):
contents before sections

I have fixed the problems in mm/filemap.c and added lots of kernel-doc to
that file (posted to the linux-mm mailing list Mon.  2006-June-12).

The real goal (as requested by Andrew Morton) is to allow the short
function description to be more than one line long.  This patch is both a
kernel-doc checker and a tool en route to that goal.

8ad2914d9c [PATCH] checkstack: print module names
Finding "init_module" high stack usage problems is challenging when there
are over 1600 "init_module" functions in the kernel tree, so make
checkstack.pl print out the filename where the stack usage occurs.  This is
useful for code built as loadable modules.

For built-in code, it just prints the kernel image file name, like
"vmlinux".  Examples:

(before patch:)
0x0000000d callback:					1928
0xffffffff81678c09 huft_build:				1560
0x0018 init_module:					1512

(after patch:)
0x0000000d callback [divacapi]:				1928
0xffffffff81678c09 huft_build [vmlinux]:		1560
0x0018 init_module [hdaps]:				1512

Also change one if-series to use elsif to cut down on unneeded tests.

05189497d1 [PATCH] kernel-doc: drop leading space in sections
Drop leading space of kernel-doc section contents.

"Section" data (contents) are split from the section header
(e.g., Note: below is a section header:
 * Note: list_empty on entry does not return true after this, the entry is
 * in an undefined state.
).

Currently the data/contents begins with a space and is left that way, which
causes it to look bad when printed (in text mode; see example below), so
just remove the leading space.

Note:

list_empty on entry does not return true after this, the entry is in an
undefined state.

15fde67518 kbuild: support for %.symtypes files
Here is a patch that adds a new -T option to genksyms for generating dumps of
the type definition that makes up the symbol version hashes. This allows to
trace modversion changes back to what caused them. The dump format is the
name of the type defined, followed by its definition (which is almost C):

  s#list_head struct list_head { s#list_head * next , * prev ; }

The s#, u#, e#, and t# prefixes stand for struct, union, enum, and typedef.
The exported symbols do not define types, and thus do not have an x# prefix:

  nfs4_acl_get_whotype int nfs4_acl_get_whotype ( char * , t#u32 )

The symbol type defintion of a single file can be generated with:

  make fs/jbd/journal.symtypes

If KBUILD_SYMTYPES is defined, all the *.symtypes of all object files that
export symbols are generated.

The single *.symtypes files can be combined into a single file after a kernel
build with a script like the following:

for f in $(find -name '*.symtypes' | sort); do
    f=${f#./}
    echo "/* ${f%.symtypes}.o */"
    cat $f
    echo
done \
| sed -e '\:UNKNOWN:d' \
      -e 's:[,;] }:}:g' \
      -e 's:\([[({]\) :\1:g' \
      -e 's: \([])},;]\):\1:g' \
      -e 's: $::' \
      $f \
| awk '
/^.#/   { if (defined[$1] == $0) {
            print $1
            next
          }
          defined[$1] = $0
        }
        { print }
'

When the kernel ABI changes, diffing individual *.symtype files, or the
combined files, against each other will show which symbol changes caused the
ABI changes. This can save a tremendous amount of time.

Dump the types that make up modversions

ac031f26e8 kbuild: add option for stripping modules while installing them
Add option for stripping modules while installing them.

This function adds support for stripping modules while they are being
installed.  CONFIG_DEBUG_KERNEL (which will probably become more
popular as developers use kdump) causes the size of the installed
modules to grow by a factor of 9 or so.

Some kernel package systems solve this problem by stripping the debug
information from /lib/modules after running "make modules_install",
but that may not work for people who are installing directly into
/lib/modules --- root partitions that were sized to handle 16 megs
worth of modules may not be quite so happy with 145 megs of modules,
so the "make modules_install" never succeeds.

This patch allows such users to request modules_install to strip the
modules as they are installed.

	(2) For each module, lists the modules and their exported symbols, on
	                  which it depends.

	the report can be generated by executing:
	perl scripts/export_report

29b0c89953 kbuild: append git revision for all untagged commits
adds revision suffix for untagged commits that are reachable from a tag

I'm bisecting and don't get the -g...... suffix.  The reason is, that

	git name-rev --tags HEAD

returns e.g.

	HEAD tags/v2.6.17-rc1^0~1067

which is currently good enough for setlocalversion to skip the suffix.
This introduces a dependecy to grep -E, which should be fine.

b817f6feff kbuild: check license compatibility when building modules
Modules that uses GPL symbols can no longer be build with kbuild,
the build will fail during the modpost step.
When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol
then warn during modpost so author are actually notified.

The actual license compatibility check is shared with the kernel
to make sure it is in sync.
