MFC r323206: Enable dtrace support for mips64 and the ERL kernel config

2018-04-16T14:39:04Z

Turn on the required options in the ERL config file, and ensure that the fbt module is listed as a dependency for mips in the modules/dtrace/dtraceall/dtraceall.c file.

MFC r329388, r331441 and r331898, to bring the -CURRENT ck version.

r329388: 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. r331441: In __sync_bool_compare_and_swap(), return true if the returned value is the same as the expected one, not the desired one. r331898: 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.

MFC r329859,r329860: Float protection in stand

2018-04-06T19:17:59Z

r329859: Do not include float interfaces when using libsa. We don't support float in the boot loaders, so don't include interfaces for float or double in systems headers. In addition, take the unusual step of spiking double and float to prevent any more accidental seepage. r329860: Floaty McFloatface is funnier...

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

kern_sig.c: ANSIfy and remove archaic register keyword Sponsored by: The FreeBSD Foundation MFC r318389 (by emaste): Remove register keyword from sys/ and ANSIfy prototypes A long long time ago the register keyword told the compiler to store the corresponding variable in a CPU register, but it is not relevant for any compiler used in the FreeBSD world today.
