armv6 and armv7 systems already were 1000Hz. The other armv5 were a mix of 100 and 1000. This changes them to 1000. Should there be issues, we can add options HZ=100 to the systems that have bad performance at the drop of a hat. mips is a lot more complicated. But most of the systems are already 1000HZ. The hardware exceptions are all fast enough to run at 1000Hz. MALTA is our primary emulator, and history has shown emulators tend to like 100Hz better, so run those systems at 100Hz. As with arm, any system that shows a huge performance regression can reverted to 100Hz easily. This was going to be committed well in advance of the 13 branch, but it was delayed and forgotten til now. Discussed on: #bsdmips ages ago Sponsored by: Netflix
