ifmcstat(8) noses in kernel memory too much, and thus is very tentative

45116d3e78 Make sure that the flags for the XPT_DEV_ADVINFO CCB are initialized
properly.

If there is garbage in the flags field, it can sometimes include a
set CDAI_FLAG_STORE flag, which may cause either an error or
perhaps result in overwriting the field that was intended to be
read.

sys/cam/cam_ccb.h:
	Add a new flag to the XPT_DEV_ADVINFO CCB, CDAI_FLAG_NONE,
	that callers can use to set the flags field when no store
	is desired.

sys/cam/scsi/scsi_enc_ses.c:
	In ses_setphyspath_callback(), explicitly set the
	XPT_DEV_ADVINFO flags to CDAI_FLAG_NONE when fetching the
	physical path information.  Instead of ORing in the
	CDAI_FLAG_STORE flag when storing the physical path, set
	the flags field to CDAI_FLAG_STORE.

sys/cam/scsi/scsi_sa.c:
	Set the XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE when
	fetching extended inquiry information.

sys/cam/scsi/scsi_da.c:
	When storing extended READ CAPACITY information, set the
	XPT_DEV_ADVINFO flags field to CDAI_FLAG_STORE instead of
	ORing it into a field that isn't initialized.

sys/dev/mpr/mpr_sas.c,
sys/dev/mps/mps_sas.c:
	When fetching extended READ CAPACITY information, set the
	XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE instead of
	setting it to 0.

sbin/camcontrol/camcontrol.c:
	When fetching a device ID, set the XPT_DEV_ADVINFO flags
	field to CDAI_FLAG_NONE instead of 0.

sys/sys/param.h:
	Bump __FreeBSD_version to 1100061 for the new XPT_DEV_ADVINFO

6b2a43801c On my Lenovo T400, a Atheros 2413 has a problem powering up
sometimes. It will power up wrong and identify itself badly:

cardbus0: <network, ethernet> at device 0.0 (no driver attached)
cardbus0: <simple comms, UART> at device 0.1 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.2 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.3 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.4 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.5 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.6 (no driver attached)
cardbus0: <old, non-VGA display device> at device 0.7 (no driver attached)

All the higher numbered functions (.2 and above) have a config space
of all 0's. This smells a bit like a special debug mode, but the
current atheros driver doesn't cope. It is unclear if this card is
just a flake, or if we're doing something wrong in the power-up
sequence.

Put a work around into the code that tests for this rather unusual
condition. If we power a CardBus device up, and the device says it is
multi-function, and any of the functions have a 0 device ID, try the
power-up sequence again.

766a186dd8 Remove drti.o's dependency on libelf. This makes it possible to add DTrace
probes to userland programs and libraries without also needing to link
libelf.

dtrace -G places the __SUNW_dof symbol at the beginning of the DOF (DTrace
probe and provider metdata) section in the generated object file; drti.o
now just uses this symbol to locate the section. A complication occurs
when multiple dtrace-generated object files are linked together, since the
__SUNW_dof symbol defined in each file is global. This is handled by
using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has
been linked with the generated object file. Upstream, this is done using a
linker feature not present in GNU ld.

e0f41bfbfb release: use xz via pipe when compressing the tarballs.
libarchive(3) doesn't support the new liblzma API yet, but this change
allows us to enable multi-threaded xz compression.
``make release'' should now finish in half the time on a machine with
several cores and fast disks (our typical build server).

This behaviour only applies when building a release and it doesn't
affect buildworld/installworld.  To disable threaded xz compression,
set XZ_THREADS=1.
