memory: move core typedefs to qemu/typedefs.h
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
exec: remove useless declarations from memory-internal.h
hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.Right now there are many catch-all headers in include/hw/ARCH dependingon cpu.h, and this makes it necessary to compile these files per-target.However, fixing this does not belong in these patches....
cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.Explicitly zero them on reset since they were located beforebreakpoints.
Pass PowerPCCPU to kvmppc_handle_halt().

exec: Pass CPUState to cpu_reset_interrupt()
Move it to qom/cpu.c to avoid build failures depending on include orderof cpu-qom.h and exec/cpu-all.h.
Change opaques of various ..._irq_handler() functions to theappropriate CPU type to facilitate using cpu_reset_interrupt()....
cpu: Pass CPUState to cpu_interrupt()
Move it to qom/cpu.h to avoid issues with include order.
Change pc_acpi_smi_interrupt() opaque to X86CPU.
tcg: Don't make exitreq flag a local temporary
The value is not actually live across basic blocks, so there's noneed for the local property. This eliminates storing the temporaryto its home location at the branch.

gen-icount.h: Rename gen_icount_start/end to gen_tb_start/end
The gen_icount_start/end functions are now somewhat misnamed since theyare useful for generic "start/end of TB" code, used for more than justicount. Rename them to gen_tb_start/end.

Handle CPU interrupts by inline checking of a flag
Fix some of the nasty TCG race conditions and crashes by implementingcpu_exit() as setting a flag which is checked at the start of each TB.This avoids crashes if a thread or signal handler calls cpu_exit()...
tcg: Document tcg_qemu_tb_exec() and provide constants for low bit uses
Document tcg_qemu_tb_exec(). In particular, its return value is acombination of a pointer to the next translation block and someextra information in the low two bits. Provide some #defines for...
Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()
The setjmp() function doesn't specify whether signal masks are saved andrestored; on Linux they are not, but on BSD (including MacOSX) they are.We want to have consistent behaviour across platforms, so we should...
cpu: Move running field to CPUState
Pass CPUState to cpu_exec_{start,end}() functions.
cpu: Move exit_request field to CPUState
Since it was located before breakpoints field, it needs to be reset.
cpu: Move current_tb field to CPUState
Explictly NULL it on CPU reset since it was located before breakpoints.
Change vapic_report_tpr_access() argument to CPUState. This alsoresolves the use of void* for cpu.h independence.Change vAPIC patch_instruction() argument to X86CPU....
cpu: Move host_tid field to CPUState
Change gdbstub's cpu_index() argument to CPUState now that CPUArchStateis no longer used.
TCG: Move translation block variables to new context inside tcg_ctx: tb_ctx
It's worth to clean-up translation blocks variables and move theminto one context as was suggested by Swirl.Also if we use this context directly inside tcg_ctx, then itspeeds up code generation a bit....
tci: Fix broken build (regression)
s390x-linux-user now also uses GETPC. Instead of adding it to the list oftargets which use GETPC, the macro is now defined unconditionally.
This avoids future build regressions like this one:

cpu-defs.h: Drop qemu_work_item prototype
Commit c64ca8140e9c21cd0d44c10fbe1247cb4ade8e6e (cpu: Movequeued_work_{first,last} to CPUState) moved the qemu_work_item fieldsaway. Clean up the now unused prototype.

exec: Return CPUState from qemu_get_cpu()
Move the declaration to qemu/cpu.h and add documentation.The implementation still depends on CPUArchState for CPU iteration.
cpu: Move nr_{cores,threads} fields to CPUState
To facilitate the field movements, pass MIPSCPU to malta_mips_config();avoid that for mips_cpu_map_tc() since callers only access MIPS ThreadContexts, inside TCG helpers.
cpu: Move numa_node field to CPUState
cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using anegative offset. Therefore the field is placed last in CPUState.
Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.
Move common parts of mips cpu_state_reset() to mips_cpu_reset()....

memory: introduce memory_region_test_and_clear_dirty
This function avoids having to do two calls, one to test the dirty bit, andother to reset it.

protect the ramlist with a separate mutex
Add the new mutex that protects shared state between ram_save_liveand the iothread. If the iothread mutex has to be taken togetherwith the ramlist mutex, the iothread shall always be outside.

exec: change ramlist from MRU order to a 1-item cache
Most of the time, only 2 items will be active (from/to for a string operation,or code/data). But TCG guests likely won't have gigabytes of memory, sothis actually goes down to 1 item.
