8201f1a29c tcg: Remove the TCG_GUEST_DEFAULT_MO definition globally
By directly using TCGCPUOps::guest_default_memory_order,
we don't need the TCG_GUEST_DEFAULT_MO definition anymore.

d11bf649d5 page-vary: Restrict scope of TARGET_PAGE_BITS_MIN
The only place we really need to know the minimum is within
page-vary-target.c.  Rename the target/arm TARGET_PAGE_BITS_MIN
to TARGET_PAGE_BITS_LEGACY to emphasize what it really means.
Move the assertions related to minimum page size as well.

e92dd33224 target: Define TCG_GUEST_DEFAULT_MO in 'cpu-param.h'
accel/tcg/ files requires the following definitions:

  - TARGET_LONG_BITS
  - TARGET_PAGE_BITS
  - TARGET_PHYS_ADDR_SPACE_BITS
  - TCG_GUEST_DEFAULT_MO

The first 3 are defined in "cpu-param.h". The last one
in "cpu.h", with a bunch of definitions irrelevant for
TCG. By moving the TCG_GUEST_DEFAULT_MO definition to
"cpu-param.h", we can simplify various accel/tcg includes.

7d8cbbabcb accel/tcg: Relax va restrictions on 64-bit guests
We cannot at present limit a 64-bit guest to a virtual address
space smaller than the host.  It will mostly work to ignore this
limitation, except if the guest uses high bits of the address
space for tags.  But it will certainly work better, as presently
we can wind up failing to allocate the guest stack.

Widen our user-only page tree to the host or abi pointer width.
Remove the workaround for this problem from target/alpha.
Always validate guest addresses vs reserved_va, as there we
control allocation ourselves.

74433bf083 tcg: Split out target/arch/cpu-param.h
For all targets, into this new file move TARGET_LONG_BITS,
TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS,
TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES.

Include this new file from exec/cpu-defs.h.

This now removes the somewhat odd requirement that target/arch/cpu.h
defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the
bulk of the includes within target/arch/cpu.h to the top.
