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!

# Added support for GEODE CPU
[PATCH] biarch compiler support for i386 This allows the i386 architecture to be built on a system with a biarch compiler that defaults to x86-64, merely by specifying ARCH=i386. As previously discussed, this uses the equivalent logic to the ppc port. Signed-Off-By: H.

[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

kbuild: remove GCC_VERSION This was causing some ordering problems. Remove the up-front evaluation and just revaluate the compiler version each time we need it.

install:
[PATCH] kbuild/i386: re-introduce dependency on vmlinux for install target, and add kernel_install Removing the dependency on vmlinux for the install target raised a few complaints, so instead a new target i added: kernel_install. kernel_install will install the kernel just like the ordinary install target. The only difference is that install has a dependency on vmlinux, kernel_install does not. Therefore kernel_install is the best choice when accessing the kernel over a NFS mount or as another user. kernel_install is similar to modules_install in the fact that neither does a full kernel compile before performing the install. In this way they are good for root use. Also added back the dependency on vmlinux for the install target so peoples scripts are no longer broken.
