Subject: [PATCH 12/33] linux-user: Fix 32-on-64 mmap for x86_64
When running a 32 bit guest on a 64 bit host, we can run into trouble while
calling the host's mmap() because it could potentially give us a 64 bit
return value which the guest can't interpret.
There are 2 ways of dealing with this:
1) Only do MAP_FIXED mmap calls and implement our own vm management in QEMU
2) Tell the kernel that we only want mappings in the lower 32 bits
Way 1 is very involved and hard to do. It's been advocated forever now but
nobody sat down to actually implement it.
Way 2 is easy. It's what this patch does. However, it only works on x86_64
because that's the only platform implementing the MAP_32BIT flag. Since most
people are on x86_64 though, I think it's a good enough compromise for now
though

Subject: [PATCH 29/33] linux-user: add binfmt wrapper for argv[0] handling
When using qemu's linux-user binaries through binfmt, argv[0] gets lost
along the execution because qemu only gets passed in the full file name

We don't implement the timer_create syscall, but shouting out loud
about it breaks some %check tests in OBS, so better ignore it silently.

Subject: [PATCH 33/33] linux-user: reserve 4GB of vmem for 32-on-64
When running 32-on-64 bit guests, we should always reserve as much
virtual memory as we possibly can for the guest process, so it can
never overlap with QEMU address space.
Fortunately we already have the infrastructure for that. All that's
missing is some sane default value to also make use of it!
