2017-10-09UPSTREAM: kbuild: Consolidate header generation from ASM offset informationMatthias Kaehlcke
Largely redundant code is used in different places to generate C headers from offset information extracted from assembly language output. Consolidate the code in Makefile.lib and use this instead.

2015-07-01time: Remove development rules from Kbuild/MakefileThomas Gleixner
time.o gets rebuilt unconditionally due to a leftover Makefile rule which was placed there for development purposes. Remove it along with the commented out always rule in the toplevel Kbuild file. Fixes: 0a227985d4a9 'time: Move timeconst.h into include/generated' Reported-by; Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Nicholas Mc Guire <der.herr@hofr.at>
2015-05-19time: Move timeconst.h into include/generatedNicholas Mc Guire
kernel/time/timeconst.h is moved to include/generated/ and generated by the top level Kbuild. This allows using timeconst.h in an earlier build stage.

2015-04-02kbuild: do not add $(bounds-file) and $(offsets-file) to targetsMasahiro Yamada

2010-10-19x86, asm: Fix CFI macro invocations to deal with shortcomings in gasJan Beulich
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).

2010-03-11kbuild: Really don't clean bounds.h and asm-offsets.hMichal Marek
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 $(no-clean-files) variable to really skip such files in Makefile.clean. Signed-off-by: Michal Marek <mmarek@suse.cz>
2009-12-12kbuild: move asm-offsets.h to include/generatedSam Ravnborg
The simplest method was to add an extra asm-offsets.h file in arch/$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.

Adjust the asm symlink support so we do not create the symlink unless really needed. We check the precense of include/asm-$ARCH by checking for the system.h file.

2008-04-28kbuild: create a way to create preprocessor constants from C expressionsChristoph Lameter
The use of enums create constants that are not available to the preprocessor when building the kernel (f.e. MAX_NR_ZONES).

2007-05-02kbuild: complain about missing system callsSam 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 implemented The file scripts/checksyscalls.sh list a number of legacy system calls that are ignored because they only makes sense on i386 systems.

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.

2005-09-09kbuild: mips use generic asm-offsets.h supportSam Ravnborg

2005-09-09kbuild: full dependency check on asm-offsets.hSam Ravnborg
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>
