New architectures only define the renameat2() system call, which was added in Linux 3.15. Define rename() and renameat() as wrappers for it if necessary.

Various coding style fixes checkpatch warns about. The goal is not to be 100% checkpatch compliant, but to have more consistent coding style. As this is a trivial patch serie, will land in 24 hours in klibc git, unless of course ml review hits a bugger. Checked with size(3) that the generated kinit, fstype, ipconfig and nfsmount are the same. maximilian attems (4): [klibc] ipconfig: reduce

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:

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.
