git-smp-nolinux-apic commit cf9ba913445e940dbab95a906e6788ebb2258ef3

smp: Fix build with default parameters

We need to automatically disable linux groups before automatically
enabling apic.

x86_64: disable linux groups early

So we enable APIC by default.

git-div0 commit eec7037c885f6e54bf8f22d421d6abc55a2cd667

idt_inittab: Fix terminator entry

Better fill a complete entry, which is always two pointers, both in
MACH_PV_DESCRIPTORS and !MACH_PV_DESCRIPTORS case.

For the x86_64 case, only half a pointer was actually recorded, leaving
to garbage getting registered in the idt. This was noticed by division
by zero getting double-faults.

Thanks Pellescours for the initial investigation!

git-mach_port_set_ktype commit fdfca0e86009c5a7b188fa39e939de800a73391d

Add mach_port_set_ktype RPC to set ktype of a user port

For now, we only allow a newly-introduced MACH_PORT_KTYPE_USER_DEVICE type
that makes ipc_kmsg_copyin_body use page lists, which keep them in a busy
state that prevents them from being paged out.

git-set_timeout commit 8d456cd9e417e9787481df15736b5f1c55cbc870

git-clock-backward commit c33f27196d9cb072d48bf5389bb64ad99a0d735a

mach_clock: Fix monotonic clock sometimes going backwards

Between reading mtime and reading hpclock_read_counter,
there may be an interrupt that updates mtime, therefore
we need a check to perform the clock read process again
in this case.

TESTED: on UP using:

```
\#include <stdio.h>
\#include <time.h>

int main()
{
struct timespec ts, now;
int i;
int cnt = 0;

clock_gettime(CLOCK_MONOTONIC, &ts);

for (i = 0; i < 10000000; i++) {
clock_gettime(CLOCK_MONOTONIC, &now);
if ((now.tv_nsec < ts.tv_nsec) && (now.tv_sec <= ts.tv_sec)) {
printf("BACKWARDS\n");
cnt++;
printf(" %u %09lu\n %u %09lu\n\n",
ts.tv_sec, ts.tv_nsec,
now.tv_sec, now.tv_nsec
);
}
ts = now;
}
printf("went backwards %d out of %d times\n", cnt, i);
return 0;
}
```

Before the change, some backward transitions were detected.
After this change, none were detected.

git-set-size-limit commit 9ae4d99c1d1e7c9c0977cebb4df9b86fa92cca94

Implement per-task virtual memory limit

Only import the header for now so glibc starts supporting it, and libpager
protects itself from it.
