similar to: [PATCH klibc 0/5] klibc architecture fixes

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. This is also available as a git tree at:

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:

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.

Hi All: We have some patches to port klibc to ArmV8. The first set of patches from Neil Williams fixes the build issues. The second set of patches from Anil Singhar fixes functionalities. The following files have changed in the second set of patches ------------------------------------------------------------------------------------------ usr/include/arch/aarch64/klibc/archconfig.h

Hi, I?ve gone through the mailing list archives and hereby want to resubmit my pending patches. Most are independent of each other, except the m68k patch which will only be complete if sigsuspend is also fixed. (It can be applied before that, though.) http://www.zytor.com/pipermail/klibc/2012-January/003173.html [PATCH] fix m68k support Resubmitted here as 0005. While there was a question from

This fixes a segmentation fault in the system call's error handling path with dynamically-linked binaries on PowerPC64 little endian. The system call stub wasn't loading up r2 with the appropriate TOC value in its global entry point. The r2 setup code comes from the FUNC_START macro in gcc [1] and an equivalent one can also be found in the LOCALENTRY macro in glibc [2]. On the ELFv2 ABI

Use klibc way to define a system dependent preprocessor definition: disabled by default and enabled for newer arm. Based on a patch by vorlon that got tested on his beagleboard, should be functional equivalent.
