kbuild: full dependency check on asm-offsets.h 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 <sam@ravnborg.org>

kbuild: create a way to create preprocessor constants from C expressions 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 through the asm-offsets.c file. Generate something similar for the core kernel through kbuild.

Kbuild: allow arch/xxx to use a different source path Preparatory patch for the source merge of arch/i386 and arch/x86_64 into arch/x86.

pageflags: standardize comment inclusion in asm-offsets.h and fix MIPS Add the ability to pass comments into asm-offsets.h by generating asm output like -># comment line Mips needs this feature to preserve the comments that are in asm-mips/asm-offsets.h right now.

remove RPM_BUILD_ROOT from asm-offsets.h 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.

This patch automatically generates a warning for any new system call which is implemented on i386 but not the architecture currently being compiled.
