2005-11-22[PATCH] uml: eliminate anonymous union and clean up symlink lossageJeff Dike
This gives a name to the anonymous union introduced in skas-hold-own-ldt, allowing to build on a wider range of gccs. It also removes ldt.h, which somehow became real, and replaces it with a symlink, and creates ldt-x86_64.h as a copy of ldt-i386.h for now.

2005-09-29[PATCH] uml makefiles sanitizedAl Viro
UML makefiles sanitized: - number of generated headers reduced to 2 (from user-offsets.c and kernel-offsets.c resp.). The rest is made constant and simply includes those two. - mk_... helpers are gone now that we don't need to generate these headers - arch/um/include2 removed since everything under arch/um/include/sysdep is constant now and symlink can point straight to source tree. - dependencies seriously simplified.

2005-09-11kbuild: rename prepare to archprepare to fix dependency chainSam Ravnborg
When introducing the generic asm-offsets.h support the dependency chain for the prepare targets was changed. All build scripts expecting include/asm/asm-offsets.h to be made when using the prepare target would broke. With the limited number of prepare targets left in arch Makefiles the trivial solution was to introduce a new arch specific target: archprepare The dependency chain looks like this now: prepare | +--> prepare0 | +--> archprepare | +--> scripts_basic +--> prepare1 | +---> prepare2 | +--> prepare3 So prepare 3 is processed before prepare2 etc. This guaantees that the asm symlink, version.h, scripts_basic are all updated before archprepare is processed. prepare0 which build the asm-offsets.h file will need the actions performed by archprepare. The head target is now named prepare, because users scripts will most likely use that target, but prepare-all has been kept for compatibility. Updated Documentation/kbuild/makefiles.txt.

2005-09-10[PATCH] Uml: more cleaningPaolo 'Blaisorblade' Giarrusso
We must remove even arch/um/os-Linux/util/mk_user_constants, which we don't do. Also, Kconfig_arch must be listed only once, between CLEAN_FILES. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-09kbuild: um fix so it compile with generic asm-offsets.h supportSam Ravnborg
um has it own set of files for asm-offsets. So for now the gen-asm-offset macro is just duplicated in the um Makefile. This may well be the final solution since um is a bit special compared to other architectures - time will tell. Also added a dummy arch/um/kernel/asm-offsets.h file to keep kbuild happy.

2005-07-14[PATCH] uml: allow building as 32-bit binary on 64bit hostPaolo 'Blaisorblade' Giarrusso
This patch makes the command: make ARCH=um SUBARCH=i386 work on x86_64 hosts (with support for building 32-bit binaries). This is especially needed since 64-bit UMLs don't support 32-bit emulation for guest binaries, currently. This has been tested in all possible cases and works. Only exception is that I've built but not tested a 64-bit binary, because I hadn't a 64-bit filesystem available.

2005-07-14[PATCH] uml: reintroduce pcap supportPaolo 'Blaisorblade' Giarrusso
The pcap support was not working because of some linking problems (expressing the construct in Kbuild was a bit difficult) and because there was no user request. Now that this has come back, here's the support. This has been tested and works on both 32 and 64-bit hosts, even when "cross-"building 32-bit binaries.

2005-07-14[PATCH] uml: gcc 2.95 fix and Makefile cleanupPaolo 'Blaisorblade' Giarrusso
1) Cleanup an ugly hyper-nested code in Makefile (now only the arith. expression is passed through the host bash). 2) Fix a problem with GCC 2.95: according to a report from Raphael Bossek, .remap_data : { arch/um/sys-SUBARCH/unmap_fin.o (.data .bss) } is expanded into: .remap_data : { arch/um/sys-i386 /unmap_fin.o (.data .bss) } (because I didn't use ## to join the two tokens), thus stopping linking. Pass the whole path from the Makefile as a simple and nice fix.

With Al Viro <viro@parcelfarce.linux.theplanet.co.uk> To make sure switcheroo() can execute when we remap all the executable image, we used a trick to make it use a local copy of errno... this trick does not work with NPTL glibc, only with LinuxThreads, so use another (simpler) one to make it work anyway. Hopefully, a lot improved thanks to merging with the version of Al Viro (which had his part of problems, though, i.e. removing a fix to another bug and not fixing the problem on i386).

2005-05-05[PATCH] uml: start cross-build support : mk_user_constantsAl Viro
Beginning of cross-build fixes. Instead of expecting that mk_user_constants (compiled and executed on the build box) will see the sizeof, etc. for target box, we do what every architecture already does for asm-offsets. Namely, have user-offsets.c compiled *for* *target* into user-offsets.s and sed it into the header with relevant constants. We don't need to reinvent any wheels - all tools are already there. This patch deals with mk_user_constants. It doesn't assume any relationship between target and build environment anymore - we pick all defines we need from user-offsets.h. Later patches will deal with the rest of mk_... helpers in the same way.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
