openbsd changes of note 626

Hackerthon is imminent.

There are two signals one can receive after accessing invalid memory, SIGBUS and SIGSEGV. Nobody seems to know what the difference is or should be, although some theories have been unearthed. Make some attempt to be slightly more consistent and predictable in OpenBSD.

Introduces jiffies in an effort to appease our penguin oppressors.

Clarify that IP.OF.UPSTREAM.RESOLVER is not actually the hostname of a server you can use.

Switch acpibat to use _BIX before _BIF, which means you might see discharge cycle counts, too.

Assorted clang compatibility. clang uses -Oz to mean optimize for size and -Os for something else, so make gcc accept -Oz so all makefiles can be the same. Adjust some hardlinks. Make sure we build gcc with gcc.

The SSL_check_private_key function is a lie.

Switch the amd64 and i386 compiler to clang and see what happens.

We are moving towards using wscons (wstpad) as the driver for touchpads.

Dancing with the stars, er, NET_LOCK().

clang emits lots of warnings. Fix some of them. Turn off a bunch of clang builtins because we have a strong preference that code use our libc versions. Some other changes because clang is not gcc.

Among other curiosities, static variables in the special .openbsd.randomdata are sometimes assumed to be all zero, leading the clang optimizer to eliminate reads of such variables.

Some more pledge rules for sed. If the script doesn’t require opening new files, don’t let it.

Backport a bajillion fixes to stable. Release errata.

RFC 1885 was obsoleted nearly 20 years ago by RFC 2463 which was obsoleted over 10 years ago by RFC 4443. We are probably not going back.

Update libexpat to 2.2.3.

vmm: support more than 3855MB guest memory.

Merge libdrm 2.4.82.

Disable SSE optimizations on i386/amd64 for SlowBcopy. It is supposed to be slow. Prevents crashes when talking to memory mapped video memory in a hypervisor.
