This adds mcount recording and updates dynamic ftrace for ARM to work
with the new ftrace dyamic tracing implementation. It also adds support
for the mcount format used by newer ARM compilers.
With dynamic tracing, mcount() is implemented as a nop. Callsites are
patched on startup with nops, and dynamically patched to call to the
ftrace_caller() routine as needed.

On ARM, we have two ABIs, and the ABI used is controlled via a config
option. Object files built with one ABI can't be merged with object
files built with the other ABI. So, record_mcount.pl needs to use the
same compiler flags as the kernel when generating the object file with
the mcount locations. Ensure this by passing CFLAGS to the script.

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.

config B

$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.

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.

savedefconfig will save a minimal config to a file
named "defconfig".
The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.
The implementation was tested against several minimal
configs for arm which was created using brute-force.
There was one regression related to default numbers
which had their valid range further limited by another symbol.
Sample:
config FOO
int "foo"
default 4
config BAR
int "bar"
range 0 FOO
If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.
This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

When we add a new config symbol save the file/line
so we later can refer to their location.
The information is saved as a property to a config symbol
because we may have multiple definitions of the same symbol.
This has the side-effect that a symbol always has
at least one property.

Rename to a name that better match the other kconfig targets.
listnewconfig shall read as:
- list new options compared to current configuration
New options are now written to stdout so one can redirect the output.
Do not exit with an error code if there is new options.
These are feature changes compared to the original
nonint_oldconfig - but as this feature has not yet been in a
released kernel it should not matter.
It is still possible to do:
make listnewconfig
lookup new config options in Kconfig*
edit .config

The list of options supported by conf is growing
and their abbreviation did not resemble anything usefull.
So drop the single letter options in favour of long options.
The long options are named equal to what we know from
the make target.
The internal implmentation was changed to match this,
resulting in much more readable code.
Support for short options is dropped - no one is supposed
to call this program direct anyway.

There seems to be a kconfig bug due to MODULES not always being
evaluated if no .config is found. Take the following Kconfig as an
example:
config MODULES
def_bool y
config FOO
def_tristate m
With no .config, the following configuration is generated:
CONFIG_MODULES=y
CONFIG_FOO=y
With an empty .config, the following:
CONFIG_MODULES=y
CONFIG_FOO=m
Tristate choice statements can also exhibit the problem, due to having an
implicit rev_dep (select) containing "m".
The problem is that MODULES is never evaluted in conf_read_simple() unless
there's a .config. The following patch fixes this.

nconfig segfaults when help text contains the character '%'. For a quick
example, navigate to the kernel compression options and get the help for
bzip2. Doing so triggers a call to mvwprintw() with a string containing
'%' and no extra arguments to fill in the specifier's value. Fix this
case by printing the literal string retrieved from the kconfig.

I found this issue in a locally patched 2.6.32.x, current kernels have
moved the offending code to an __init function which is skipped by
recordmcount.pl, so the bug is not currently being exercised.
However, I think the patch is still a good idea, to avoid future
problems if _mcount were to ever have its address taken in normal
code.
This is what I originally saw:
Although arch/mips/kernel/ftrace.c is built without -pg, and thus
contains no calls to _mcount, it does use the address of _mcount
in ftrace_make_nop(). This was causing relocations to be emitted
for _mcount which recordmcount.pl erronously took to be _mcount
call sites. The result was that the text of ftrace_make_nop()
would be patched with garbage leading to a system crash.
In non-module code, all _mcount call sites will have R_MIPS_26
relocations, so we restrict $mcount_regex to only match on these.

The 'source' builtin is a bash alias to the '.' (dot) builtin. While the
former is supported only by bash, the latter is specified in POSIX and
works fine with all POSIX-compliant shells I am aware of.
The '$_' special parameter is specific to bash. It is partially
supported in dash too but it always evaluates to the current script path
(which causes the script to enter a loop recursively re-executing
itself). This is why I have replaced the two occurences of '$_' with the
explicit parameter.
The 'local' builtin is another example of bash-specific code. Although
it is supported by all POSIX-compliant shells I am aware of, it is not
part of POSIX specification and thus the code should not rely on it
assigning a specific value to the local variable. Moreover, the 'posh'
shell has a limited version of 'local' builtin not supporting direct
variable assignments. Thus, I have broken one of the 'local'
declarations down into a (non-POSIX) 'local' declaration and a plain
(POSIX-compliant) variable assignment.

The "select" statement in Kconfig files allows the enabling of options
even if they have unmet direct dependencies (i.e. "depends on" expands
to "no"). Currently, the "depends on" clauses are used in calculating
the visibility but they do not affect the reverse dependencies in any
way.
The patch introduces additional tracking of the "depends on" statements
and prints a warning on selecting an option if its direct dependencies
are not met.

The initial pass at the generic ABI assumed that wait4() could be
easily expressed using waitid(). Although it's true that wait4()
can be built on waitid(), it's awkward enough that it makes more
sense to continue to include wait4 in the generic syscall ABI.
Since there is already a deprecated wait4 in the ABI, this change
converts that wait4 into old_wait, and puts wait4 in the next
available slot for new supported syscalls, after the platform-specific
syscalls at number 260.

Now that we run scripts/setlocalversion during every build, it makes
sense to move all the localversion logic there. This cleans up the
toplevel Makefile and also makes sure that the script is called only
once in 'make prepare' (previously, it would be called every time due to
a variable expansion in an ifneq statement). No user-visible change is
intended, unless one runs the setlocalversion script directly.

It just hit me.
It's the offset calculation in reloc_location() which overflows:
return (void *)elf->hdr + sechdrs[section].sh_offset +
(r->r_offset - sechdrs[section].sh_addr);
E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

A 'coccicheck' target is added. It can be called with four different
modes. Each one generates a different kind of output, i.e. context,
patch, org, report, according to the corresponding mode to be
activated.
The new target calls the 'coccicheck' front-end in the 'scripts'
directory with the MODE argument. Every SmPL file in the
subdirectories of 'scripts/coccinelle' is then given to the front-end
and applied to the entire source tree.
The four modes behave as follows:
'report' generates a list in the following format:
file:line:column-column: message
'patch' proposes a fix, when possible.
'context' highlights lines of interest and their context in a
diff-like style. Lines of interest are indicated with '-'.
'org' generates a report in the Org mode format of Emacs.

The fixes include:
- removing extra whitespaces in the if-statements
- moving the if-statement from around the -r to the -T
- adding a second arg to cmd_gensymtypes to simplify the options passed
to genksyms.
Tested by instrumenting genksyms and seeing what options were passed in

Quite a few Kconfig symbols contain lowercase letters. The current
checkkconfigsymbols.sh code only contains A-Z in the regexp it uses to
find config symbols in source code, so it comes up with the wrong symbol
to look for in Kconfig files and then generates false positives when it
doesn't find that wrong symbol. For example checking drivers/net
generates a false positive for MAC89 because the the actual config
option is MAC89x0.
Fix this by also adding a-z to the regexp.
