2014-05-02linux-user: avoid using glibc internals in _syscall5 and in definition of ↵Natanael Copa
target_sigevent struct Use the public sigset_t instead of the glibc specific internal __sigset_t in _syscall. Calculate the sigevent pad size is calculated in similar way as kernel does it instead of using glibc internal field _pad. This is needed for building with musl libc.

2014-05-02linux-user: Handle arches with llseek instead of _llseekJames Hogan
Recently merged kernel ports (such as OpenRISC and Meta) have an llseek system call instead of _llseek. This is handled for the host architecture by defining __NR__llseek as __NR_llseek, but not for the target architecture. Handle it in the same way for these architectures, defining TARGET_NR__llseek as TARGET_NR_llseek.

It has been pointed out on LKML that the alpha umount syscall numbers are named wrong, and a patch to rectify that has been posted for 3.11. Glibc works around this by treating NR_umount as NR_umount2 if NR_oldumount exists. That's more complicated than we need in QEMU, given that we control linux-user/*/syscall_nr.h.

2013-09-10linux-user: Allow targets to specify a minimum uname releasePeter Maydell
For newer target architectures, glibc can be picky about the kernel version: for example, it will not run on an aarch64 system unless the kernel reports itself as at least 3.8.0. Accommodate this by enhancing the existing support for faking the kernel version so that each target can optionally specify a minimum version: if the user doesn't force a specific fake version then we will override with the minimum required version only if the real host kernel version is insufficient. Use this facility to let aarch64 report a minimum of 3.8.0. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1378235544-22290-21-git-send-email-peter.maydell@linaro.org

This includes behaviour changes fixing bugs on cris, x86-64, m68k, openrisc and unicore32. cris had explicit but wrong handling; the others were just incorrectly using QEMU's default, which happened to be the equivalent of CONFIG_CLONE_BACKWARDS.
