The previous misuse of sys_sigqueue() was sending random register or
stack garbage to 64-bit targets. The freebsd32 implementation preserves
the sival_int member of value when signaling a 64-bit process.
Document the mixed ABI implementation of union sigval and the
incompability of sival_ptr with pointer integrity schemes.

Refactoring done in r317703 broke -c, -l, and -L flags implying
suppression of match printing. Fortunately this is just a matter of not
doing any printing of the resulting matches and context printing was not
broken in this refactoring.
Add some regression tests since this area may still see further
refactoring, include different context flags as well even though they
were not broken in this case.

makefs(1) has a number of signedness warnings (when built with higher
WARNS), most of which can be addressed by careful application of casts
in makefs itself.
There is one case where a signedness warning arises from the blksize
macro, so must be addressed in the macro itself.

Background:
The same VM object might be shared by multiple processes and the
mm_struct is usually freed when a process exits.
Grab a reference on the mm_struct while the vmap is in the
linux_vma_head list in case the first process which inserted a VM
object has exited.

Elan hw v.4 touchpads often sends touchpad release packet right after

With fstyp(8) being updated to detect exfat in base r312003, it seems
like a good time to add support for auto-mounting SDXC cards -- which
use exfat by default.
The user will need to locally compile and install sysutils/fusefs-exfat
for this to succeed; logs a message to that effect when not installed.

From user report, the errors are seen:
error 1
error 1
gptzfsboot: error 1 lba 4294967288
gptzfsboot: error 1 lba 1
gptzfsboot: no ZFS pools located, can't boot
The first two errors above are from issuing INT13 EAX=0x4800, meaning we
need to check if EDD is available and use EAX=0x800 if not.
For an workaround I'm using the similar idea as in biosdisk.c - first probe
ah=8h, then check if we have EDD.
Note we would like to see the correct disk size info, but we *may*
get away with anything >64MB, so we could at least test 2 zfs pool labels
on whole disk setup and not to freak out the INT13 interface.
If we get away with initial disk probing, then we have partition sizes from
the partition table and we should be able to complete the disk probing.
Note: this update does not provide full fix to all errors, but we get
the drvsize() errors removed.

Extended attributes and their particular implementation in linux are
different from FreeBSD so in this case we have started diverging from
