Andreas Färber d77953b94f 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 also
resolves the use of void* for cpu.h independence.
Change vAPIC patch_instruction() argument to X86CPU.

Avi Kivity a8170e5e97 Rename target_phys_addr_t to hwaddr
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"
                        | xargs s/target_phys_addr_t/hwaddr/g' origin

Avi Kivity ac1970fbe8 memory: per-AddressSpace dispatch
Currently we use a global radix tree to dispatch memory access.  This only
works with a single address space; to support multiple address spaces we
make the radix tree a member of AddressSpace (via an intermediate structure
AddressSpaceDispatch to avoid exposing too many internals).

A side effect is that address_space_io also gains a dispatch table.  When
we remove all the pre-memory-API I/O registrations, we can use that for
dispatching I/O and get rid of the original I/O dispatch.

Avi Kivity 7762c2c1e0 memory: rename 'exec-obsolete.h'
exec-obsolete.h used to hold pre-memory-API functions that were used from
device code prior to the transition to the memory API.  Now that the
transition is complete, the name no longer describes the file.  The
functions still need to be merged better into the memory core, but there's
no danger of anyone using them.

Blue Swirl 89c33337fd Remove unused CONFIG_TCG_PASS_AREG0 and dead code
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,
remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.

Remove dyngen-exec.h and all references to it. Although included by
hw/spapr_hcall.c, it does not seem to use it.

Remove unused HELPER_CFLAGS.

The comment about the return address from get_page_addr_code() was
well out of date as phys_ram_base has not existed for some time.

Max Filippov 56eb21e158 cputlb: fix watchpoints handling
Cleanup commit e554861766 have changed
code_address calculation in the tlb_set_page function in case of access
to a page with a watchpoint. This caused QEMU segfault in the xtensa
test_break unit test. Fix it by moving code_address assignment above
memory_region_section_get_iotlb call.

Blue Swirl cc5bea608d cputlb: prepare private memory API for public consumption
Fold is_ram_rom and is_ram_rom_romd() into callers.

Change is_romd() and section_addr() to take MemoryRegion
instead of MemoryRegionSection for consistency and
use memory_region_ prefix.
