initramfs.cpio.gz being build in usr/ and included in the
kernel was not rebuild when the included files changed.
To fix this the following was done:
- let gen_initramfs.sh generate a list of files and directories included
in the initramfs
- gen_initramfs generate the gzipped cpio archive so we could simplify
the kbuild file (Makefile)
- utilising the kbuild infrastructure so when uid/gid root mapping changes
the initramfs will be rebuild
With this change we have a much more robust initramfs generation.

This patch puts the infrastructure in place to allow for a reordering of
functions based inside the vmlinux. The general idea is that it is possible
to put all "common" functions into the first 2Mb of the code, so that they
are covered by one TLB entry. This as opposed to the current situation where
a typical vmlinux covers about 3.5Mb (on x86-64) and thus 2 TLB entries.
This is done by enabling the -ffunction-sections flag in gcc, which puts
each function in its own ELF section, so that the linker can then order them
in a way defined by the linker script.
As per previous discussions, Linus said he wanted a "static" list for this,
eg a list provided by the kernel tarbal, so that most people have the same
ordering at least. A script is provided to create this list based on
readprofile(1) output. The included list is provisional, and entirely biased
on my own testbox and me running a few kernel compiles and some other
things.
I think that to get to a better list we need to invite people to submit
their own profiles, and somehow add those all up and base the final list on
that. I'm willing to do that effort if this is ends up being the prefered
approach. Such an effort probably needs to be repeated like once a year or
so to adopt to the changing nature of the kernel.
Made it a CONFIG with default n because it increases link times
dramatically.

With the current way of generating the Makefile in the output directory
for builds outside of the source tree, specifying real targets (rather
than phony ones) doesn't work in an already (partially) built tree, as
the stub Makefile doesn't have any dependency information available.
Thus, all targets where files may actually exist must be listed
explicitly and, due to what I'd call a make misbehavior, directory
targets must then also be special cased.

Section mismatch is identified as references to .init*
sections from non .init sections. And likewise references
to .exit.* sections outside .exit sections.
.init.* sections are discarded after a module is initialized
and references to .init.* sections are oops candidates.
.exit.* sections are discarded when a module is built-in and
thus references to .exit are also oops candidates.
The checks were possible to do using 'make buildcheck' which
called the two perl scripts: reference_discarded.pl and
reference_init.pl. This patch just moves the same functionality
inside modpost and the scripts are then obsoleted.
They will though be kept for a while so users can do double
checks - but note that some .o files are skipped by the perl scripts
so result is not 1:1.
All credit for the concept goes to Keith Owens who implemented
the original perl scrips - this patch just moves it to modpost.
Compared to the perl script the implmentation in modpost will be run
for each kernel build - thus catching the error much sooner, but
the downside is that the individual .o file are not always identified.

Currently scripts/setlocalversion is a Perl script that tries to figure
out the current git commit ID of a repo without using git. It also
imports Digest::MD5 without using it and generally is too big for the
small task it does. :] And it always reports a git ID, even when the
HEAD is tagged -- this is a bug.
This patch replaces it with a Bourne Shell script that uses git
commands to do the same. I can't come up with a scenario where someone
would use a git repo and refuse to install git core at the same time,
so I think it's reasonable to assume git is available.
The new script also reports uncommitted changes by adding -git_dirty to
the version string. Obviously you can't see from that _what_ has been
changed from the last commit, so it's more of a reminder that you
forgot to commit something.
The script is easily extensible: simply add a check for Mercurial (or
whatever) below the git check.
Note: the script doesn't print a newline char anymore. That's only
because it was easier to implement it that way, not a feature (or bug).
'make kernelrelease' doesn't care.

Here's the patch for modalias support for input classes. It uses
comma-separated numbers, and doesn't describe all the potential keys (no
module currently cares, and that would make the strings huge). The
changes to input.h are to move the definitions needed by file2alias
outside __KERNEL__. I chose not to move those definitions to
mod_devicetable.h, because there are so many that it might break compile
of something else in the kernel.
The rest is fairly straightforward.

Remove support for lxdialog --checklist
The checklist lxdialog functionality is not used by menuconfig
(only the radiolist variant is used) and supporting it would
significantly complicate the forthcoming liblxdialog API.

Fix out-of-tree builds for the tar-pkg targets
When I wrote the buildtar script, I didn't even think about
out-of-tree builds because I didn't use these back then. This patch
throughoutly uses ${objtree} instead of `pwd`.
Also, the kernel version is no longer manually built. Instead, it will
properly use $KERNELRELEASE . Installing modules is only done if
CONFIG_MODULES is set.

If the file .kconfig.d is missing then make sure to run
'make silentoldconfig', since we have no way to detect if
a Kconfig file has been updated.
-kconfig.d is created by kconfig and is removed as part
of 'make clean' so the situation is likely to occur in reality.

This is a one-line change to parse.y.
To take advantage of this the scripts/genksyms/*_shipped files needs to
be rebuild - this is the next patch.
When a .c file contains:
DEFINE_PER_CPU(struct foo_s *, bar);
the .cpp output looks like:
__attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar;
With the existing parse.y, the value inside the paranthesis of
__typeof__() does not evaluate as a type_specifier and therefore
per_cpu__bar does not get assigned a type for genksyms which results in
the EXPORT_PER_CPU_SYMBOL() not generating a CRC value.
I have compared the Modules.symvers with and without this
patch and for ia64's defconfig, the only change is:
Before 0x00000000 per_cpu____sn_nodepda vmlinux
After 0x9d3f3faa per_cpu____sn_nodepda vmlinux
per_cpu____sn_nodepda was the original source of my problems.

This patch fixes a problem when we use well known kernel symbols as module
names.
For example, if module source name is current.c, idle_stack.c or etc.,
we have a bad KBUILD_MODNAME value.
For example, KBUILD_MODNAME will be "get_current()" instead of "current", or
"(init_thread_union.stack)" instead of "idle_task".
The trick is to define a stringify macro on the commandline - named
KBUILD_STR for namespace reasons - and then to stringify the module
name.
There are a few uses of KBUILD_MODNAME throughout the tree but the usage
is for debug and will not be harmed by this change so left untouched for now.
While at it KBUILD_BASENAME was changed too. Any spinlock usage in the
unix module would have created wrong section names without it.
Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME.

This is the patch for the following issue:
In include/linux/module.h, "__crc_" and "__ksymtab_" are hard
coded to be the prefix for some kinds of symbols (CRC symbol and
ksymtab section). But in script /mod/modpost.c,
MODULE_SYMBOL_PREFIX##"__crc_" is used as the prefix to search CRC
symbols. So if an architecture (such as h8300 or Blackfin) defines
MODULE_SYMBOL_PREFIX as not NULL ("_"), modpost will always warn about
"no invalid crc".
And it is the same with KSYMTAB_PFX.
