Based on tcg-next. The last two patches from v1 are now part of
"[PATCH 0/6] exec: Cleanup watchpoints" from richard.
Fix and refactore some things around probe_write() in s390x code. Introduce
probe_write() for CONFIG_USER_ONLY.
This is the first step of some changes necessary to handle fault-safe
access accross multiple pages on s390x. The next step is making
probe_write() return an address, similar to tlb_vaddr_to_host(), and
introduing probe_read().
v1 -> v2:
- "tcg: Factor out CONFIG_USER_ONLY probe_write() from s390x code"
-- Perform only a single !guest_addr_valid(addr) check.
- "tcg: Enforce single page access in probe_write()"
-- Also add the check for CONFIG_USER_ONLY
