			Changes tlb_*() functions to take CPUState instead of CPUArchState, as they don't require the full CPUArchState. This makes it easier to decouple target-(in)dependent code.

|  * at least _user and _kernel) as well as _data versions, for all data
 | |
|  * sizes.
 | |
|  *
 | |
|  * Used by target op helpers.
 | |
|  *
 | |
|  * The syntax for the accessors is:
 | |

 | |
|  *   u    : unsigned
 | |
|  *   s    : signed
 | |
|  *
 | |

 | |
|  *   w: 16 bits

|  *   q: 64 bits

 | |
|  *     _be: for forced big endian
 | |
|  *     _le: for forced little endian
 | |
|  *
 | |
|  * mmusuffix is one of the generic suffixes "data" or "code", or "mmuidx".
 | |
|  * The "mmuidx" suffix carries an extra mmu_idx argument that specifies
 | |
|  * the index to use; the "data" and "code" suffixes take the index from
 | |
|  * cpu_mmu_index().
 | |
|  *
 | |
|  * The "mmu" suffix carries the full MemOpIdx, with both mmu_idx and the
 | |
|  * MemOp including alignment requirements.  The alignment will be enforced.
