Kernel Heap Hardening: detect frees-in-wrong-pool on on-page pools. The
detection is already implicitly done for off-page pools.

We recycle pr_slack (unused) in struct pool, and make ph_node a union in
order to recycle an unsigned int in struct pool_item_header. Each time a
pool is created we atomically increase a global counter, and register the
current value in pp. We then propagate this value in each ph, and ensure
they match in pool_put.

This can catch several classes of kernel bugs and basically makes them
unexploitable. It comes with no increase in memory usage and no measurable
increase in CPU cost (inexistent cost actually, just one check predicted
false).

Don't create the driver's workqueue twice!

The driver is modular, so its modcmd(MOULE_CMD_INIT) always gets called

there's no need to also create it in swwdog_attach() (used to attach a
device instance).

Fix a tiny race in setregs and linux_setregs. Between the moment we set
pcb_flags to zero, and the moment cpu_segregs64_zero resets pcb_gs, we may
be preempted.

If this happens, and if the calling LWP was a 32bit thread, when switching
back to that LWP, the context switcher sees that PCB_COMPAT32 is not set in
pcb_flags and tries to perform a 64bit context switch; but pcb_gs contains
a 32bit GDT descriptor, and not a 64bit GS.base value. The wrmsr therefore
faults because the value is non-canonical, and this fault is fatal.

Rearrange the code so that the update of pcb_flags and pcb_gs/pcb_fs is non
interruptible. This fixes the problem, tested with a reproducer (which
therefore doesn't work anymore).
