Refactor BN_uadd() and BN_usub().
Unlike bn_add_words()/bn_sub_words(), the s2n-bignum bignum_add() and
bignum_sub() functions correctly handle inputs with differing word
lengths. This means that they can be called directly, without needing to
fix up any remaining words manually.
Split BN_uadd() in two - the default bn_add() implementation calls
bn_add_words(), before handling the carry for any remaining words.
Likewise split BN_usub() in two - the default bn_sub() implementation
calls bn_sub_words(), before handling the borrow for any remaining words.
On amd64, provide an implementation of bn_add() that calls s2n-bignum's
bignum_add() directly, similarly with an implementation of bn_sub() that
calls s2n-bignum's bignum_sub() directly.

vmd(8): fix an interrupt storm in ns8250.
On slower hosts, such as those in a nested virtualization scenario
of OpenBSD guest inside OpenBSD atop Linux KVM, ns8250 can cause a
race between the kevent firing and the vcpu being kicked by an
assert/deassert of the irq.
The end user experiences a "stuck" serial console and the host will
see a vmd process peg the cpu.
This change only toggles the irq if we were in a position of being
ready to receive data on the device so while the kevent might
continuously fire, the vcpu will not be kicked repeatedly.

Rework cpu_init_secondary() such that it can be used for both the initial
powerup and for wakeup from deeper sleep states.
Adjust cpu_suspen_primary() to use pmap_extract() to find the physical
address of the entry point and struct cpu_info.

Replace selwakeup() with KNOTE() in pppac(4) and pppx(4)
Use the same mutex for read and write side klists. It would be overkill
to have dedicated locks.
Remove klist_invalidate() from pppacclose() because pppac(4) does not
have forced device detach. When the close routine gets called, there
should be no open file descriptors pointing the device, and consequently
the klists should be empty.

Take a simple approach for saving and restoring PKRU if the host

This functionality is still gated behind amd64 pmap checking for
operation under a hypervisor as well as vmm masking the cpuid bit

We have determined that enough HV have correct PKU handling now,
so don't be paranoid about it anymore. What does this mean? If the HV
above you is broken, userland programs in the guest could crash, the guest
might even be quite unusable. So fix the hypervisor. The best way to
raise the bar on hypervisor quality is for guests to behave like they
are on a real machine, and then sucky hypervisors have to get fixed.
ps. if using vmd as your hypervisor, use syspatch...
