c03d07d01d Put the __insn_barrier() inside the spinloop for the DIAGNOSTIC case, so 
that we have a barrier for the DIAGNOSTIC case too.

c52ff7f9d5 Fixes from David Boggs; in his words: 
/sys/net/if_spppvar.h says:

	"Lower layer drivers that are always ready to communicate
	(like hardware HDLC) can shortcut pp_up from pp_tls,
	and pp_down from pp_tlf."

	When I follow those instructions, I get a kernel stack
	overflow as soon as I open the HDLC device.

	Here is the loop:
	 sppp_ioctl calls sppp_lcp_open
	 sppp_lcp_open calls sppp_open_event
	 sppp_open_event calls sppp_lcp_tls
	 sppp_lcp_tls calls pp_tls
	 pp_tls is the SHORTCUT to sppp_lcp_up
	 sppp_lcp_up calls spp_lcp_open
	 ...and around we go until the stack overflows.

	The fix is to reverse the order of the action (tls)
	and the state change (from INITIAL to STARTING) in
	sppp_open_event.

	There is a similar loop during closing:
	 sppp_ioctl calls sppp_lcp_close
	 sppp_lcp_close calls sppp_close_event
	 spp_close_event calls sppp_lcp_tlf
	 sppp_lcp_tlf calls pp_tlf
	 pp_tlf is the SHORTCUT to sppp_lcp_down
	 sppp_lcp_down calls sppp_lcp_close
	 ...and around we go until the stack overflows.

	The fix is to reverse the order of the action (tlf)
	and the state change (from STARTING to INITIAL) in
	sppp_close_event.

	Separately, while I was discovering this, I noticed
	that pp_tlf was being called unconditionally rather
	than first checking to see if it is NULL.  pp_tlf
	is a callout from sppp to the hdlc device driver.
	Elsewhere in sppp, this is always checked for NULL
	before calling it, and the comments in if_spppvar.h
	imply that filling it in is optional.

	From spppvar.h:
	"These functions need to be filled in by the lower layer
	(hardware) drivers if they request notification from the
	PPP layer whether the link is actually required."
	This clearly says that pp_tlf and pp_tls are optional
	and so sppp must check before calling them.

b3e7e1b010 Better implementation of PaX MPROTECT, after looking some more into the 
code and not trying to use temporary solutions.

Lots of comments and help from YAMAMOTO Takashi, also thanks to the PaX
author for being quick to recognize that something fishy's going on. :)

Hook up in mmap/vmcmd rather than (ugh!) uvm_map_protect().

Next time I suggest to commit a temporary solution just revoke my
commit bit.

64f867a645 Redo previous fix properly. Original code had a typo caused by very similar 
function and variable names.  We need to protect tag comparison b/c we don't
want to perform it against an uninitialized tag.

igsfb_pci_is_console(pci_chipset_tag_t pc, pcitag_t tag)
	{

delete "igsfb_pci_is_console &&" as the address of igsfb_pci_is_console
is always true.  thanks gcc4.
