Raw Normal View History

Linux-2.6.12-rc2 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!

m68k: make multi_defconfig the default defconfig It seems to match the intention behind multi_defconfig to make it the default defconfig.

KBUILD_DEFCONFIG := multi_defconfig
m68k: use KBUILD_DEFCONFIG The default defconfig should be one from arch/m68k/configs/ arch/m68k/defconfig was not exactly identical to amiga_defconfig but also considering how long they have been without any update that doesn't seem to have been on purpose.

m68k: runtime patching infrastructure Add the basic infrastructure to allow runtime patching of kernel and modules to optimize a few functions with parameters, which are only calculated once during bootup and are otherwise constant. Use this for the conversion between virtual and physical addresses.

m68k: Use cc-cross-prefix The cc-cross-prefix is new and developed on request from Geert Uytterhoeven. With cc-cross-prefix it is now much easier to have a few default cross compile prefixes and defaulting to none - if none of them were present. ARCH maintainers are expected to pick up this feature soon.

kbuild: enable 'make CFLAGS=...' to add additional options to CC The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.
