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:

Hi, after a year, I decided to hack on klibc again. I?ve reworked both the patch to add mkstemp(), discussing to use AT_RANDOM as cheap entropy source on IRC (if there will ever be another entropy consumer, I can quickly write a minimal arc4random() seeded from it, as it has only 16 octets), capable of making a working mksh (static and shared) on amd64/xen, and the m68k support code, leading to

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

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

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.
