2011-02-17linux-user: in linux-user/strace.c, tswap() is uselessLaurent Vivier
Syscall parameters are already swapped by the caller.

2011-02-09linux-user: fix build errors for mmap2-only portsMike Frysinger
The current print_mmap func is only enabled when the target supports the mmap syscall, but both mmap and mmap2 syscalls use it. This leads to a build failure when the target supports mmap2 but not mmap. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Riku Voipio <riku.voipio@nokia.com>

Howabout something like this: commit eb8387cb0eda32a18880664eb5f0ca5c8bf05b45 Author: Riku Voipio <riku.voipio@iki.fi> Date: Thu Jun 18 22:44:31 2009 +0300 Subject: linux-user: include futex defines directly Since some common distributions have broken linux/futex.h, stop including it.
