should be a value past to pthread_attr_setguardsize, not a rounded up value.
Also fix a stack size matching bug in thr_stack.c, now stack matching code
uses number of pages but not bytes length to match stack size, so for example,
size 512 bytes and size 513 bytes should both match 1 page stack size.

special signal-delivery protections for setugid processes. In the
event that a system is relying on "unusual" signal delivery to
processes that change their credentials, this can be used to work
around application problems.
Also, add SIGALRM to the set of signals permitted to be delivered to
setugid processes by unprivileged subjects.

we're on a 32-bit/64-bit bus or not. Use this to decide if we should
set the PCI dual-address cycle enable bit in the C+ command register.
(Enabling DAC on a 32-bit bus seems to do bad things.)
Also, initialize the C+ command register early in the re_init() routine.
The documentation says this register should be configured first.
in6_pcbpurgeif0(LIST_FIRST(udbinfo.listhead), ifp);
in6_pcbpurgeif0(LIST_FIRST(ripcbinfo.listhead), ifp);
The problem here is that udbinfo.listhead and ripcbinfo.listhead are
not initialized during the device probe/attach phase of the kernel
boot process. So if, for example, a network driver calls ether_ifattach()
in its foo_attach() routine and then decides that something is wrong
and calls ether_ifdetach() to reverse the process, we will panic trying
to dereference the uninitialized list head pointers. (Though the
same sequence of events performed after the kernel has come up works
file, i.e. doing kldload if_foo from multiuser.)
Change this to:
if (udbinfo.listhead != NULL)
in6_pcbpurgeif0(LIST_FIRST(udbinfo.listhead), ifp);
if (ripcbinfo.listhead != NULL)
in6_pcbpurgeif0(LIST_FIRST(ripcbinfo.listhead), ifp);
to avoid the NULL pointer dereferences.

We simply use the detected FIFO size to determine whether we have
