Load the magic into the right register for the comparison in _longjmp
Add ATAIOCCOMMAND ioctl form COMPAT_NETBSD32

This enables SMART monitoring by a netbsd32 binary.
Snapshot of work in progress:
Add support xorg wsfb driver. Tested on evbmips/loongson
Support WSDISPLAYIO_GETCMAP/WSDISPLAYIO_PUTCMAP. Tested on evbmips/loongson
Slightly bump ramdisk size, so the content fits even when compiled with
gcc 4.8 (usually binaries are smaller or same size, this increase is
strange)
Import compiler-rt r200007. Use .size on all assembler functions.
Reimplement ARM division based on Matt Thomas's common version.
As requested by mrg@, since there is still a small window during which
the in-module ref-counting can fail, completely disable auto-unload.
CID 1163170, 1164171, resource leak
CID 1161172 double free
CID 1164169: integer overflow
Fix locking botch, and ...
Yes, we want to be careful because the sizes are different.
sigaction until 1.4 had an int sigmask, don't trash the stack.
It is wishful thinking that vn_readdir will return dirent12 structures.
need to lock the process.
remove useless flag mangling. It is done already.
Fix awk programs to use $$ so make doesn't eat each $
Add raid disk nodes for the install images
Add raid to the install kernel
close uhidev only when it was successfully opened.
Increase VM_KERNEL_PT_PAGES from 2 to 4 for x68k.

X68030 with 8MB or 12MB RAM (which is default for most X68030s)
now gets "pmap_enter_ptpage: can't get KPT page" panic again
with VM_KERNEL_PT_PAGES=2 while it works with >=14MB.
3 is enough to boot for now, but I also add a spare.

I guess this is because the post netbsd-6 vmem(9) bootstrap
changes require more kernel memory before MD pmap_init().

Note1:	netbsd-6 (which also pulls physmem detection changes
	that affect nptpages) doesn't have this problem.
Note2:	other hp300 pmap based m68k ports might have the same issue,
	but at least 12MB luna68k works with VM_KERNEL_PT_PAGES=2
	so I think it depends on kernel size and/or iomapsize.
fix monitor mode channel.
