ac09878158 x86: Account for MCE in cpu_has_work
MCEs can be injected asynchronously, so they can also terminate the halt
state.

eda48c344f inline cpu_halted into sole caller
All implementations are now the same, and there is only one caller,
so inline the function there.

63a54736f3 target-i386: fix crash on x86 32bit linux host with hw breakpoint exceptions
If you make use of hw breakpoints on a 32bit x86 linux host, qemu
will segmentation fault when processing the exception.

The problem is that the value of env is stored in $ebp in the op_helper
raise_exception() function, and it can have the wrong value when
calling it from non generated code.

It is possible to work around the problem by restoring the value of
env before calling raise_exception() using a new helper function that
takes (CPUState *) as one of the arguments.

b09ea7d55c Handle init/sipi in a main cpu exec loop. (v2)
This should fix compilation problem in case of CONFIG_USER_ONLY.

Currently INIT/SIPI is handled in the context of CPU that sends IPI.
This patch changes this to handle them like all other events in a main
cpu exec loop. When KVM will gain thread per vcpu capability it will
be much more clear to handle those event by cpu thread itself and not
modify one cpu's state from the context of the other.

7d99a001df Add noreturn function attribute
Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.

[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h.
I've been told that these conflicts will get resolved in the future
(/me will try to have a look as well - as time permits). ]

d9957a8b0f x86 cleanup
Remove some unnecessary includes, add needed includes, move prototypes to
cpu.h to suppress missing prototype warnings.

Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock,
cpu_unlock, restore_native_fp_state, save_native_fp_state).

Make some functions and data static (f15rk, parity_table, rclw_table,
rclb_table, raise_interrupt, fpu_raise_exception), they are not used
outside op_helper.c anymore.

Make some x86_64 and user only code conditional to avoid warnings.

Document where each function is implemented in cpu.h and exec.h.

2cbd949d7a Common cpu_loop_exit prototype

6ebbf39000 Replace is_user variable with mmu_idx in softmmu core,
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
