riastradh | cpuio.h: Use uint8_t, not bool.
In principle bool can only store two values, 0 and 1, but occupies
eight bits of storage (on all NetBSD platforms to my knowledge),
meaning there are 254 other values which might be trap
representations which would be undefined behaviour to use but which
userland can control the bits of.
To placate ubsan, just use uint8_t here instead of bool. No bump or
anything because the ABI is the same: one-byte field with one-byte
alignment.

dsl | Add definitions so that the i386 cpuctl can issue IOC_CPU_UCODE_GET_VERSION
on amd64 kernels.
XXX This ioctl is horrid - writes into an unsized userspace buffer.

Extend the CPU microcode update framework to support Intel x86 CPUs.
Contrary to the AMD implementation, it doesn't use xcalls to distribute
the update to all CPUs but relies on cpuctl(8) to bind itself to the
right CPU -- to keep it simple and avoid possible problems with
hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right
part for the present CPU model but relies on userland to prepare
files with specific filenames. I'll commit a pkg for this in a minute
(pkgsrc/sysutils/intel-microcode).
The ioctl interface changed; compatibility is provided (should be
limited to COMPAT_NETBSD6 as soon as this is available).

cegger | include limits.h for PATH_MAX. Reported by njoly@.

cegger | Support CPU microcode loading via cpuctl(8).
Implemented and enabled via CPU_UCODE kernel config option
for x86 and Xen Dom0.
Tested on different AMD machines with different
CPU families.

Add a cs_hwid field to cpustate and use this to store the ci_cpuid (hardware
ID). Report this as the HwID in cpuctl.
OK jruoho@.

ad | cpuctl:
- Add interrupt shielding (direct hardware interrupts away from the
specified CPUs). Not documented just yet but will be soon.
- Redo /dev/cpu time_t compat so no kernel changes are needed.
x86:
- Make intr_establish, intr_disestablish safe to use when !cold.
- Distribute hardware interrupts among the CPUs, instead of directing
everything to the boot CPU.
- Add MD code for interrupt sheilding. This works in most cases but there is
a bug where delivery is not accepted by an LAPIC after redistribution. It
also needs re-balancing to make things fair after interrupts are turned
back on for a CPU.
