similar to: [klibc:master] ppc64: ELFv2: Load TOC value in system call stub

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

Here's an assortment of build and run-time fixes for various architectures that we've applied in Debian. Ben. Aurelien Jarno (1): ppc64: fix struct stat Ben Hutchings (2): MIPS: Update archfcntl.h syscalls: Override detection of direct socket syscalls on i386, m68k, s390 Helge Deller (1): Add pread and pwrite 32bit syscall wrappers for parisc Mauricio Faria de Oliveira

Hi all, I'm trying to understand which ABIs are supported in the PowerPC backend and I'm getting a bit confused. Here's what I've gathered so far alongside with some questions. - In PPCSubtarget.h there's DarwinABI, SVR4ABI and ELFv2ABI. - The CodeGenerator documentation claims that the AIX PowerPC ABI is followed (with some deviations). Is this refering to the DarwinABI? -

Merge s390 and s390x into s390. Compiled and tested on s390/s390x and i386. Also cross compilation for s390/s390x tested. This patch shouldn't break the build of any architecture.
