883f5b4450 Allow to specify a character special device as a core file.
This enable us to use /dev/fwmem* as a core file.
e.g.
	ps -M /dev/fwmem0.0 -N kernel.debug
	dmesg -M /dev/fwmem0.0 -N kernel.debug
	gdb -k -c /dev/fwmem0.0 kernel.debug
You need to set target EUI64 in hw.firewire.fwmem.eui64_hi/lo before
opening the device. On the target arch, (PCI) bus address must be
equivalent to physical address.
(We cannot use this for sparc64 because of IOMMU.)

fd30158300 Remove unnecssary <vm/swap_pager.h> includes.
These were probably not cleaned up back in whatever murky past these
files were split into separate files.

c9164bea19 In kvm_openfiles/kvm_open, mark the file descriptors as close-on-exec.
Applications can not do this themselves, as the descriptors are hidden
behind the opaque `kvm_t' type.

c4b08ff306 Finish cleanup in kvm.c revisions 1.10 and 1.11 -- mark sf (swapfile)
argument to kvm_open() and kvm_openfiles() as unused.

BSD didn't read swap since kvm.c CSRG revision 5.21 (u-area is pageable
under new VM.  no need to read from swap.)

The old !NEWVM code was removed in CSRG revision 5.23 (~ten years ago).

4e7ee5ff5d Limit the amount of data copied to the error buffer to _POSIX2_LINE_MAX.
This is the documented size which the user-provided buffer must be.

4cb901960c Change the return value of kvm_read/kvm_write to be -1 on error, to
match the documented interface.

Previously it returned 0 on error.

047fa82dd0 Use kldsym(2) to lookup symbol values. This avoids the kvm_mkdb juggling
and is module aware.  Yes, this means that kvm_nlist(3) will find symbols
in loaded modules.  The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.

1e9a248e26 Don't open the swap file. The open descriptor for it hasn't been used
for over 5 years since we switched to using procfs for kvm_uread().
This cleanup was motivated by recent breakage of the default swap file
(/dev/drum) when swapon() has not been called.

6658078ab3 Allow /dev/null as path for the "/dev/mem" file, and assume that people
know what they're doing if they do that.  This will allow ps to use
the kvm_proc.c bits without having access to /dev/mem.

Fix kvm_proc.c to not need /dev/mem for access to argv/envp

26976c4aee kvm_malloc:
When malloc fails. don't try to memset NULL pointer, it cause core dump
Replace malloc+memset with calloc, theoretically it can do some
optimization of zeroing process internally

193a8fae68 Get rid of _PATH_UNIX completely; use getbootfile(3) instead.
DANGER WILL ROBINSON!
_PATH_UNIX is currently defined as the literal string "don't use this".
I am of two minds about this myself, but wanted to get something into the
tree as quickly as possible.
