Shawn Webb 838f91683a HBSD: Add userland plumbing for SpectreV1 mitigation ... Speculative Load Hardening[1] (SLH) is a mitigation technique to mitigate the SpectreV1 CPU microarchitectural bug, most commonly present in Intel CPUs. This commit introduces SLH, disabled by default, for userland. Only a single application is opted out at this time: /bin/sh. More research needed to enable SLH for /bin/sh. I have a backtrace with enough info to get me started on that. Some of the bootloader code in src/stand (the 32-bit bits) has SLH disabled. Further research needed to enable SLH for the kernel.
