Hi hpa & others. Following is a list of issues that I hope to be addressed soon so we are in even better shape for -mm inclusion. 1) rebuild initramfs when content changes. > It is a simple matter of copying in usr/Makefile from the latest > -linus kernel and replace the 10 first lines with the content from > klibc Kbuild file. 2) havesyscalls.h is not deleted after make

The following patchset implements 3 seperate series of changes. External Building ================= Patches 1 through 8 enable to use of klibc's build system while leaving the src tree pristine (and potentially read only). Specifically: - srctree=<Sources for klibc> - objtree=<Ouput directory for klibc> - KLIBCKERNELSRC=<Kernel sources> - KLIBCKERNELOBJ=<Kernel

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
