commit 6e48e160ae935a3fde656c975c3f38aaae54707c Author: Warner Losh <[email protected]> AuthorDate: 2022-02-10 21:27:08 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2022-02-10 21:32:20 +0000 powerpc: Add static asssert for context size Add a static assert for the siginfo_t, mcontext_t and ucontext_t sizes. These are de-facto ABI options and cannot change size ever. For powerpc64, also add asserts for {u,m}mcontext32_t and siginfo32.
