d2ee72a5b1 linux-user: in linux-user/strace.c, tswap() is useless
Syscall parameters are already swapped by the caller.

This patch removes useless tswap() from strace.c

$ QEMU_STRACE=1 chroot /m68k mknod myramdisk b 1 1
with tswap()
...
29944 mknod("myramdisk",026630200000) = 0
...

without tswap()

...
30042 mknod("myramdisk",S_IFBLK|0666,makedev(1,1)) = 0
...

natively:

$ strace touch mytouch
...
open("mytouch", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = 3
...

$ QEMU_STRACE=1 chroot /m68k touch mytouch
with tswap()
...
30368 open("/usr/share/locale/locale.alias",O_RDONLY) = 3
30368 fstat64(50331648,0x4080032c) = 0
...
30368 open("mytouch",O_RDONLY|O_CREAT|O_LARGEFILE|O_NOCTTY|O_NONBLOCK|0x1) = 0
...
without tswap()
...
30572 open("/usr/share/locale/locale.alias",O_RDONLY) = 3
30572 fstat64(3,0x4080032c) = 0
...
30572 open("mytouch",O_WRONLY|O_CREAT|O_LARGEFILE|O_NOCTTY|O_NONBLOCK,0666) = 0

8d9016c091 linux-user: fix build errors for mmap2-only ports
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.

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. Instead add the defines directly.
