all of the module event handlers are MP safe yet, so always acquire Giant
for now when invoking module event handlers. Eventually we can add an
MPSAFE flag or some such and add appropriate locking to all module event
handlers.
o don't assign remote/local host/port information manually between provided
struct in_conninfo and struct syncache, bcopy() it instead
o rename sc_tsrecent to sc_tsreflect in struct syncache to better capture
the purpose of this field
o rename sc_request_r_scale to sc_requested_r_scale for ditto reasons
o fix IPSEC error case printf's to report correct function name
o in syncache_socket() only transpose enhanced tcp options parameters to
struct tcpcb when the inpcb doesn't has TF_NOOPT set
o in syncache_respond() reorder stack variables
o in syncache_respond() remove bogus KASSERT()
No functional changes.

o redefine the parameter 'is_syn' to 'flags', add TO_SYN flag and adjust its
usage accordingly
o update the comments to the tcp_dooptions() invocation in
tcp_input():after_listen to reflect reality
o move the logic checking the echoed timestamp out of tcp_dooptions() to the
only place that uses it next to the invocation described in the previous
item
o adjust parsing of TCPOPT_SACK_PERMITTED to use the same style as the others
o add comments in to struct tcpopt.to_flags #defines

stations in power save: add a new q where mcast frames are stashed
and on beacon update (at DTIM) move frames from the mcast q to the
cabq and start it. This ensures the cabq is only manipulated in
one place.

MBR should have only one entry of type 0xEE, consider protective MBR
to be one, that has at least one entry of type 0xEE covering the whole

in 1999, and there are changes to the sysctl names compared to PR,
according to that discussion. The description is in sys/conf/NOTES.
Lines in the GENERIC files are added in commented-out form.

Don't enable/disable I/O space except for SAS adapters.
This fixes a problem with VMware 4.5 Workstation.
Fix an egregious bug introduced to target mode so it actually
will not panic when you first enable a lun.
Minor fixes:
Take more infor from port facts and configuration pages.

This fix is different from the patch submitted as it not only prevents
a NULL-pointer dereference, but also skips some work in this case.

vm_page_startup(). As a result, we now only lookup the tunable once
instead of looking it up once for every physical page of memory in the
system. This cuts out about a 1 second or so delay in boot on x86
systems. The delay is much larger and more noticable on sun4v apparently.

protect all linker-related data structures including the contents of
linker file objects and the any linker class data as well. Considering how
rarely the linker is used I just went with the simple solution of
single-threading the whole thing rather than expending a lot of effor on
something more fine-grained and complex. Giant is still explicitly
acquired while registering and deregistering sysctl's as well as in the
elf linker class while calling kmupetext(). The rest of the linker runs
without Giant unless it has to acquire Giant while loading files from a
non-MPSAFE filesystem.
