Some macro's and defines are needed when parsing memory, and without
compiling the kernel as -g3 they are not available in the debug-symbols.We use the pre-processor here to extract constants to a dedicated module
for the linux debugger extensionsTop level Kbuild is used to call in and generate the constants file,
while maintaining dependencies on autogenerated files in

gas prior to (perhaps) 2.16.90 has problems with passing non-
parenthesized expressions containing spaces to macros. Spaces, however,
get inserted by cpp between any macro expanding to a number and a
subsequent + or -. For the +, current x86 gas then removes the space
again (future gas may not do so), but for the - the space gets retained
and is then considered a separator between macro arguments.Fix the respective definitions for both the - and + cases, so that they
neither contain spaces nor make cpp insert any (the latter by adding
seemingly redundant parentheses).Signed-off-by: Jan Beulich

Commit 7d3cc8b tried to keep bounds.h and asm-offsets.h during make
clean by filtering these out of $(clean-files), but they are listed in
$(targets) and $(always) and thus removed automatically. Introduce a new
$(no-clean-files) variable to really skip such files in Makefile.clean.Signed-off-by: Michal Marek

The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.Signed-off-by: Sam Ravnborg

The use of enums create constants that are not available to the preprocessor
when building the kernel (f.e. MAX_NR_ZONES).Arch code already has a way to export constants calculated to the preprocessor

kernel through kbuild.Signed-off-by: Sam Ravnborg

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implementedThe file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.Other contributors to this patch are Russell King
and Stéphane JourdoisSigned-off-by: David Woodhouse

No file in rpm binary package should have the RPM_BUILD_ROOT string in it.
To simplify building of external modules, our kernel-source package
contains some temp files from the Kbuild system. asm/asm-offsets.h is one
of the files that contains the absolute path if make O=$O is used.* This file was generated by /var/tmp/kernel-source-2.6.14_rc4-build/usr/src/linux-2.6.14-rc4-2/Kbuild
Remove the $RPM_BUILD_ROOT string in the shipped tempfile.

Building asm-offsets.h has been moved to a seperate Kbuild file
located in the top-level directory. This allow us to share the
functionality across the architectures.The old rules in architecture specific Makefiles will die
in subsequent patches.Furhtermore the usual kbuild dependency tracking is now used
when deciding to rebuild asm-offsets.s. So we no longer risk
to fail a rebuild caused by asm-offsets.c dependencies being touched.With this common rule-set we now force the same name across
all architectures. Following patches will fix the rest.Signed-off-by: Sam Ravnborg
