Using separate assignment for CHECKFLAGS allows convenient redefinition of CHECK
on the command line:
make CHECK=~/bin64/sparse C=2
to use a special 64 bit version.
Introduced usage in all archs that assined values to CHECK.

Russell King reported that some gcc / bin-utils combination may result in
undefined symbols in vmlinux and implemented a check for that.
Though the cause is very valid this check has proved to be a real pain
for other users, especially sparc and um.
Short term a similar check is asked to be implemented in arch/arm*/Makefile
and long-term to bail out if too old gcc / bin-utils is used.
Long term plan awaits a new gcc / bin-utils release.

With make C=2 sparse ($(CHECK)) will be run on all .c files also if they

Usefull to run sparse on a fully compiled kernel tree.

Fixes the following error:
make: *** No rule to make target `.tmp_kallsyms2.S', needed by `.tmp_kallsyms2.o'.

Problem is that make does not know it have to visit scripts before it can use $(KALLSYMS)
$(KALLSYMS) is a dependency to .tmp_kallsyms% but make suddenly complains about
.tmp_kallsyms2 for some reasons.

Only warn if $(host-progs) and $(hostptogs-y) are not equal.
This allows external modules to use:
hostprogs-y := file ...
host-progs  := $(hostprogs-y)

This is backwards compatible and will not warn.

Localize Kconfig debug options into one file (lib/Kconfig.debug)
for easier maintenance, searching, and menu-building.

Updated to 2.6.8.

Summary of changes:

. localizes the following symbols in lib/Kconfig.debug:
    DEBUG_KERNEL, MAGIC_SYSRQ, DEBUG_SLAB, DEBUG_SPINLOCK,
    DEBUG_SPINLOCK_SLEEP, DEBUG_HIGHMEM, DEBUG_BUGVERBOSE,
    DEBUG_INFO
  and FRAME_POINTER for some instances of it (if it's freely
  user-selectable) but not for the cases where it's forced or
  it depends on some other options.
. adds DEBUG_KERNEL requirement to some DEBUG_vars;
. remove KALLSYMS from S390-specific kernel hacking menu;
  use KALLSYMS in the EMBEDDED menu instead;
. add CRIS and M68KNOMMU symbols for use in lib/Kconfig.debug;
. eliminate duplicate "General setup" labels in sparc64 config;
. whitespace cleanup;
. fixed a few trival typos;

Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

When building a kernel on platforms where the filesytem do
not distingush between upper and lower case the rule:
.S -> .s did not work.
In a normal build this is only used for linker scripts.
So create a separate rule for .lds files, and use generic cpp flags.

From: Pavel Roskin <proski@gnu.org>
The recent fixes for the external module build have fixed the major
breakage, but they left one annoyance unfixed.  If CONFIG_MODVERSIONS is
disabled, a warning is printed for every exported symbol that is has no
CRC.  For instance, I see this when compiling the standalone Orinoco
driver on Linux 2.6.6-rc3:

*** Warning: "__orinoco_down" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
*** Warning: "hermes_struct_init" [/usr/local/src/orinoco/spectrum_cs.ko]
has no CRC!
*** Warning: "free_orinocodev" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
[further warnings skipped]

I have found that the "-i" option for modpost is used for external builds,
whereas the internal modules use "-o".  The "-i" option causes read_dump()
in modpost.c to be called.  This function sets "modversions" variable
under some conditions that I don't understand.  The comment before the
modversions declarations says: "Are we using CONFIG_MODVERSIONS?"

Apparently modpost fails to answer this question.  I think it's better to
use an explicit option rather than a kludge.

The attached patch adds a new option "-m" that is specified if and only if
CONFIG_MODVERSIONS is enabled.  The patch has been successfully tested
both with and without CONFIG_MODVERSIONS.

Shouldn't we be grepping __crc_ symbols out of the System.map file?

For one thing, these can confuse readprofile.  It's algorithm is
to start at _stext, then stop when it sees a line in the System.map
which is not text (mode is one of 'T' 't' 'W' or 'w')

It will exit early if there are some intermixed __crc_* things in
there (since they are are mode 'A').

For example, in my current sparc64 kernel I have this:

00000000004cef80 t do_split
00000000004cf2a0 t add_dirent_to_buf
00000000004cf5a7 A __crc_init_special_inode
00000000004cf640 t make_indexed_dir
00000000004cf900 t ext3_add_entry

So no symbols after add_dirent_to_buf will be shown in the profiling
output of readprofile.

Implementation ported to mksysmap by Sam.
Included two System.map related fixes:
- Print "SYSMAP  System.map" during build
- Sort symbols in System.map

Patch from Marc Singer

The work already done to rectify the timer code initialization missed
a necessary change.  This patch adds a timer initialization function
to the LPD7A400 machine type.  It also makes a small correction to the
kernel configuration that is out of step with the machine specific
Kconfig.

Patch from Marc Singer

This patch aligns the lh7a40x port with the updated structure of IDE
drivers.  It also removes an unused FIQ handler.  This patch is made
in order to get the lh7a40x port to build.
