[PATCH v3 05/20] exec: Promote TARGET_PAGE_MASK to target_long |
Date: |

There are some uint64_t uses that expect TARGET_PAGE_MASK to
extend for a 32-bit, so this must continue to be a signed type.
Define based on TARGET_PAGE_BITS not TARGET_PAGE_SIZE; this
will make a following patch more clear.
This should not have a functional effect so far.
