If vmx or svm is disabled in BIOS or the device isn't supported by vmm,
modinit won't allocate these state save areas. As kmem_free panics when
passing a NULL pointer to it, loading the vmm kernel module causes a
panic too.

Currently, we handle SIGINT by calling summary() and _exit() directly from the signal handler, which we install after setup(). There are several issues with this:
* summary() is not signal safe;
* the parent is not informed about the signal;
* setup() can block on open(), and catching SIGINT at that stage will produce the correct exit status but will not print anything to stderr as POSIX demands.
Fix this by making SIGINT non-restartable, changing our signal handler to only set a flag, installing it before setup(), and checking the termination flag before and after every blocking operation, i.e. open(), read(), write().
Also add two test cases, one for catching SIGINT while opening the input and one for catching it while reading. I couldn't think of an easy way to test catching SIGINT while writing (it's certainly feasible, but perhaps not from a shell script).

Dan Nelson followed up with a suggestion to use make's built-in :ts

Do not preallocate pcpu area backing pages on early startup, only
allocate enough of KVA for pcpu[MAXCPU] and the page for BSP. Other

The previous change involved calling check_cgmagic() twice in a row
for the same CG in order to differentiate when the CG was already ok vs.
when the CG was rebuilt, but that doesn't work because the second call
(which was supposed to rebuild the CG) returns 0 (indicating that
the CG was not rebuilt) due to the prevfailcg check causing an early
failure return. Fix this by moving the rebuild part of check_cgmagic()
out into a separate function which is called by pass1() when it wants to
rebuild a CG.

After the locking protocol changed in commit 75a67bf3d0 ("AF_UNIX:

updated accordingly.
The link lock now only protects global socket lists. The PCB lock is
used to protect the link between connected PCBs, so use that. Remove an
old comment which appears to be noting that unp_conn is not set for
connected SOCK_DGRAM sockets (in one direction anyway).
