eda603f6cd docbook: warn on unused doc entries
When you don't use !E or !I but only !F, then it's very easy to miss
including some functions, structs etc.  in documentation.  To help
finding which ones were missed, allow printing out the unused ones as
warnings.

For example, using this on mac80211 yields a lot of warnings like this:

  Warning: didn't use docs for DOC: mac80211 workqueue
  Warning: didn't use docs for ieee80211_max_queues
  Warning: didn't use docs for ieee80211_bss_change
  Warning: didn't use docs for ieee80211_bss_conf

when generating the documentation for it.

1f3a66889c kernel-doc: ignore case when stripping attributes
There are valid attributes that could have upper case letters, but we
still want to remove, like for example
	__attribute__((aligned(NETDEV_ALIGN)))
as encountered in the wireless code.

Fix this by checking if the kernel source tree is the root of the git or
hg repository. No fix for svn: If the kernel source is not tracked in
the svn repository, it works as expected, otherwise determining the
'repository root' is not really a defined task.

3c955b407a fixes for using make 3.82
It doesn't like pattern and explicit rules to be on the same line,
and it seems to be more picky when matching file (or really directory)
names with different numbers of trailing slashes.

3643f849d7 kconfig: fix segfault when detecting recursive dependency
Following sample Kconfig generated a segfault:

config FOO
        bool
        select PERF_EVENTS if HAVE_HW_BREAKPOINT

config PERF_EVENTS
        bool

config HAVE_HW_BREAKPOINT
        bool
        depends on PERF_EVENTS

Fix by reverting back to a valid property if there was no
property on the stack of symbols.

The above pattern were seen in sh Kconfig.
A fix for the Kconfig file has been sent to the sh folks.

84062dd3a6 kconfig: fix savedefconfig with choice marked optional
savedefconfig failed to save the correct minimal config
when it encountered a choice marked optional.

Consider following minimal configuration:
$cat Kconfig
choice
	prompt "choice"
	optional

config A
	bool "a"

config B
	bool "b"

endchoice

$cat .config | grep -v ^#
CONFIG_A=y

$conf --savedefconfig=defconfig Kconfig

would before this fix result in an empty file, because
kconfig would assume that CONFIG_A=y is a default value.
But because the choice is optional the default is that
both A and B are =n.

Fix so we handle optional choices correct.

The manpage for cut says it will return all lines without the delimiter
unless -s is specified.

When I backed up my mecurial tree to generate modules, I found that the
scm part of localversion was turning up blank.

a64b44ead0 kconfig: fix tristate choice with minimal config
If a minimal config did not specify the value
of all choice values, the resulting configuration
could have wrong values.

Consider following example:
config M
        def_bool y
        option modules
choice
        prompt "choice list"
config A
        tristate "a"
config B
	tristate "b"
endchoice

With a defconfig like this:
CONFIG_M=y
CONFIG_A=y

The resulting configuration would have

    CONFIG_A=m

which was unexpected.

The problem was not not all choice values were set and thus
kconfig calculated a wrong value.

The fix is to set all choice values when we
read a defconfig files.

conf_set_all_new_symbols() is refactored such that
random choice values are now handled by a dedicated function.
And new choice values are set by set_all_choice_values().

This was not the minimal fix, but the fix that resulted
in the most readable code.

b998e001e6 checkpatch: fix extraneous EXPORT_SYMBOL* warnings
These are caused by checkpatch incorrectly parsing its internal
representation of a statement block for struct's (or anything else that is
a statement block encapsulated in {}'s that also ends with a ';').  Fix
this by properly parsing a statement block.

An example:

	+struct dummy_type dummy = {
	+	.foo	= "baz",
	+};
	+EXPORT_SYMBOL_GPL(dummy);
	+
	+static int dummy_func(void)
	+{
	+	return -EDUMMYCODE;
	+}
	+EXPORT_SYMBOL_GPL(dummy_func);

	WARNING: EXPORT_SYMBOL(foo); should immediately \
		follow its function/variable
	#19: FILE: dummy.c:4:
	+EXPORT_SYMBOL_GPL(dummy);

The above warning is issued when it should not be.
