Richard Henderson 5270589032 Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.
Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha.  This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place.

Nathan Froyd 0b5c1ce846 cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations.  This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently.  Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.

Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality.  I have removed
such blocks for the appropriate targets in this patch.

pbrook c276471991 The _exit syscall is used for both thread termination in NPTL applications,
and process termination in legacy applications.  Try to guess which we want
based on the presence of multiple threads.

Also implement locking when modifying the CPU list.

aliguori 6b9175478e Refactor translation block CPU state handling (Jan Kiszka)
This patch refactors the way the CPU state is handled that is associated
with a TB. The basic motivation is to move more arch specific code out
of generic files. Specifically the long #ifdef clutter in tb_find_fast()
has to be overcome in order to avoid duplicating it for the gdb
watchpoint fixes (patch "Restore pc on watchpoint hits").

j_mayer 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.
