Hi Peter & others. Here are three patches that does the following: #1 - Update kbuild part of klibc so make clean works Adds gzip including a sample kbuild file #2 - Factor out definition of usr/ to two variables #3 - Move kbuild files to reflect location in the kernel As requested in earlier mail I need a bit of guidiance of what you expect from the kernel integrated parts of klibc.

Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place
