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.

ARM: vfp: use -mfloat-abi=soft to build vfp Distros are starting to ship with toolchains defaulting to hardfloat. Using such a compiler to build the kernel fails in the VFP directory with arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP Adding -mfloat-abi=soft to the gcc command line fixes this.

[ARM] Enable VFP to be built when non-VFP capable CPUs are selected Since we pass flags to the compiler to control code generation based on the least capable selected CPU, if we want to include VFP support, we must tweak the assembler flags to allow the VFP instructions. Moreover, we must not use the mrrc/mcrr versions since these will not be recognised by the assembler. We do not convert all instructions to the VFP-equivalent (yet) since binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any other way (other than using the mrc equivalent) to encode this instruction - which is rather a problem when you have a VFP implementation which requires these instructions.
