Olivier Houchard	271ce40239	Import CK as of commit b19ed4c6a56ec93215ab567ba18ba61bf1cfbac8 ... It should fix ck_pr_[load|store]_ptr on mips and riscv, make sure no *fence instructions are used on i386, as older cpus don't support it, and make sure we don't rely on gcc builtins that can lead to calls to libatomic when linked with -O0.

Olivier Houchard	a72c9dc53f	Define CK_MD_TSO for the relevant arches (i386, amd64 and sparc64). ... Defaulting to CK_MD_RMO has the unfortunate side effect of generating memory barriers that are useless on those arches, and the even more unfortunate side effect of generating lfence/sfence/mfence on i386, even if older CPUs don't support it. This should fix the panic reported when using IPFW on a Pentium 3. Note that mfence and sfence might still be used in a few case, but that shouldn't happen in FreeBSD right now, and should be fixed upstream first. MFC after: 1 week	2018-02-16 17:50:06 +00:00
