So rather than trying to keep it up-to-date, lets get rid of it. This allows us to do some very welcome cleanup of sparc32 support.

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!

sparc32: always define boot_cpu_id Define boot_cpu_id in single-processor kernels as well. This is to support architectures which can boot on other than CPU0. Sam Ravnborg has written the cleanup parts by extracting boot_cpu_id from smp_32.c into setup_32.c and cleaned up sun4d_irq.c. boot_cpu_id was initialized before BSS was cleared in sun4c_continue_boot, instead boot_cpu_id is set to 0xff to avoid BSS. If boot_cpu_id is untouched (0xff) by bootup code it will be overwritten to 0. boot_cpu_id4 is automatically calculated in common code.
