[PATCH 00/18] target/s390x: Prohibit target_ulong and TARGET_PAGE_SIZE uses

Posted by Philippe Mathieu-Daudé 1 month ago

- Restrict WatchPoint API to TCG
- Replace target_ulong uses by vaddr / hwaddr / uint64_t
- Remove the single TARGET_PAGE_SIZE
- Remove CONFIG_KVM from headers
- Compiles objects as target_common_system_arch, effectively
  forbidding further target_ulong / TARGET_PAGE_SIZE uses.

Philippe Mathieu-Daudé (18):
  target/s390x: Restrict WatchPoint API to TCG
