We need to synchronize registers after a reset has been performed. The current code does that in qemu_system_reset(), load_normal_reset() and modified_clear_reset() for all vcpus. After SIGP (INITIAL) CPU RESET, this needs to be done for the targeted vcpu as well, so let's call cpu_synchronize_post_reset() in the respective handlers.

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.

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 initrd, close to the top of RAM, this does not take into account other 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] With this patch: [ 0.000000] init_memory_mapping: [mem 0x07000000-0x07fdffff] [ 0.000000] RAMDISK: [mem 0x07112000-0x07fdffff] So linuxboot is able to use the 64k that were added as padding for QEMU <= 2.1.

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.

GDB assumes that watchpoint set via the gdbstub remote protocol will behave in the same way as hardware watchpoints for the target. In particular, whether the CPU stops with the PC before or after the insn which triggers the watchpoint is target dependent. Allow guest CPU code to specify which behaviour to use. This fixes a bug where with guest CPUs which stop before the accessing insn GDB would manually step forward over what it thought was the insn and end up one insn further forward than it should be. We set this flag for the CPU architectures which set gdbarch_have_nonsteppable_watchpoint in gdb 7.7: ARM, CRIS, LM32, MIPS and Xtensa.
