Let QEMU propagate the cpu state to kvm. If kvm doesn't yet support it, it is
silently ignored as kvm will still handle the cpu state itself in that case.
The state is not synced back, thus kvm won't have a chance to actively modify
the cpu state. To do so, control has to be given back to QEMU (which is already
done so in all relevant cases).
Setting of the cpu state can fail either because kvm doesn't support the
interface yet, or because the state is invalid/not supported. Failed attempts
will be traced

This patch makes sure that halting a cpu and stopping a cpu are two different
things. Stopping a cpu will also set the cpu halted - this is needed for common
infrastructure to work (note that the stop and stopped flag cannot be used for
our purpose because they are already used by other mechanisms).
A cpu can be halted ("waiting") when it is operating. If interrupts are
disabled, this is called a "disabled wait", as it can't be woken up anymore. A
stopped cpu is treated like a "disabled wait" cpu, but in order to prepare for a
proper cpu state synchronization with the kvm part, we need to track the real
logical state of a cpu.

Until now, when a s390 cpu was stopped or halted, the number of running
CPUs was tracked in a global variable. This was problematic for migration,
so Jason came up with a per-cpu running state.
As it turns out, we want to track the full logical state of a target vcpu,
so we need real s390 cpu states.
This patch is based on an initial patch by Jason Herne, but was heavily
rewritten when adding the cpu states STOPPED and OPERATING. On the way we
move add_del_running to cpu.c (the declaration is already in cpu.h) and
modify the users where appropriate.
Please note that the cpu is still set to be stopped when it is
halted, which is wrong. This will be fixed in the next patch. The LOAD and
CHECK-STOP state will not be used in the first step.

Even though hw/i386/pc.c tries to compute a valid loading address for the

data that is malloced into that memory by SeaBIOS.
Luckily we can easily look at the memory map to find out how much memory is
used up there. This patch places the initrd in the first four gigabytes,
below the first hole (as returned by INT 15h, AX=e801h).
Without this patch:
[ 0.000000] init_memory_mapping: [mem 0x07000000-0x07fdffff]
[ 0.000000] RAMDISK: [mem 0x0710a000-0x07fd7fff]

Merge remote-tracking branch 'remotes/riku/tags/pull-linux-user-20141006-2' into staging
linux-user pull for 2.2
Clearest linux-user patches sent to the list since august,
Apart from Mikhails patch, the rest are quite trivial.
v2: check for CONFIG_TIMERFD only after it has been defined

translate-all.c: memory walker initial address miscalculation
linux-user: don't include timerfd if not needed
linux-user: Simplify timerid checks on g_posix_timers range
linux-user: Convert blkpg to use a special subop handler
linux-user: Enable epoll_pwait syscall for ARM

The initial base address is miscalculated in walk_memory_regions().
It has to be shifted TARGET_PAGE_BITS more. Holder variables are
extended to target_ulong size otherwise they don't fit for MIPS N32
(a 32-bit ABI with a 64-bit address space) and qemu won't compile.
The issue led to incorrect debug output of memory maps and a
mis-formed coredumped file.

Without this, builds on older systems fail with:
qemu/linux-user/syscall.c:61:25: warning: sys/timerfd.h: No such file or directory
v2: fix the usual case where CONFIG_TIMERFD is enabled..

We check whether the passed in timer id is negative on all calls
that involve g_posix_timers.
However, these checks are bogus. First off we limit the timer_id to
16 bits which is not what Linux does. Then we check whether it's negative
which it can't be because we masked it.
We can safely remove the masking. For the negativity check we can just
treat the timerid as unsigned and only check for upper boundaries.

The blkpg ioctl can take different payloads depending on the opcode in
its payload structure. Create a new special ioctl handler that can only
deal with partition style ones for now.
This patch fixes running parted for me.
