Paolo Bonzini 93e22326d6 softmmu: make do_unaligned_access a method of CPU
We will reference it from more files in the next patch.  To avoid
ruining the small steps we're making towards multi-target, make
it a method of CPU rather than just a global.

Stefan Weil 1246b259f8 misc: Replace 'struct QEMUTimer' by 'QEMUTimer'

Andreas Färber 00b941e581 cpu: Turn cpu_get_phys_page_debug() into a CPUClass hook
Change breakpoint_invalidate() argument to CPUState alongside.

Since all targets now assign a softmmu-only field, we can drop helpers
cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd().

Prepares for changing cpu_memory_rw_debug() argument to CPUState.

Andreas Färber 6e42be7cd1 cpu: Drop unnecessary dynamic casts in *_env_get_cpu()
A transition from CPUFooState to FooCPU can be considered safe,
just like FooCPU::env access in the opposite direction.
The only benefit of the FOO_CPU() casts would be protection against
bogus CPUFooState pointers, but then surrounding code would likely
break, too.

This should slightly improve interrupt etc. performance when going from
CPUFooState to FooCPU.
For any additional CPU() casts see 3556c233d9
(qom: allow turning cast debugging off).

Andreas Färber fe31e73742 target-alpha: Register VMStateDescription for AlphaCPU
Commit b758aca1f6 (target-alpha: Enable
the alpha-softmmu target.) introduced cpu_{save,load}() functions but
didn't define CPU_SAVE_VERSION, so they were never registered.

Drop cpu_{save,load}() and register the VMStateDescription via DeviceClass.
This operates on the AlphaCPU object instead of CPUAlphaState.

Andreas Färber 97a8ea5a3a cpu: Replace do_interrupt() by CPUClass::do_interrupt method
This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.

It will also allow to override the interrupt handling for certain CPU
families.

Andreas Färber fadf982584 cpu: Introduce ENV_OFFSET macros
Introduce ENV_OFFSET macros which can be used in non-target-specific
code that needs to generate TCG instructions which reference CPUState
fields given the cpu_env register that TCG targets set up with a
pointer to the CPUArchState struct.

Andreas Färber c92458538f target-alpha: Avoid leaking the alarm timer over reset
Move the timer from CPUAlphaState to AlphaCPU to avoid the pointer being
zero'ed once we implement reset. Would cause a segfault in
sys_helper.c:helper_set_alarm().

This also simplifies timer initialization in Typhoon.
