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!

sh: Simplify and lock down the ISA tuning. The ISA tuning as it is today can not cope with all of the different variations that are possible, so all we can do is a best attempt based on the CPU family. The DSP and FPU generation are already at odds with each other, and the nommu tuning we weren't handling at all. Additionally, for platforms that never had an FPU, the -nofpu variant never existed, meaning that we would lose out on family granular tuning completely in certain cases. With tat out of the way, we were also using -up versions, allowing for later instructions that branched off of a particular subset of the ISA, but are not actually reflected on the hardware being targetted. This leads to some confusion, and the possibility of bogus instructions on older parts. Kill that off and lock it down to the family being built for specifically.

[PATCH] sh: Move CPU subtype configuration to its own Kconfig Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat. Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things like cache configuration are also moved to this new location. This also adds support for strict CPU tuning on newer cores, which requires the addition of as-option.

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.
