Add extra safety locking when clobbering xfer->flags_int.started in start and
stop functions, because xfer->flags_int is also updated by the USB controller,
under the controller lock.
Import two PCI quirks from Linux
- Add quirk for ATI SB600 and SB700 to free SMB controller
- Correct schedule sleep time to 10us on the VIA ehci controller
We used force all of the GPIO pins low first and then
enable the ones we want. This has been changed to better
match the ADMtek's reference design to avoid setting the
power-down configuration line of the PHY at the same time
it is reset.
- FIFO's are always opened separately in read and write direction even if the
actual device is opened for read and write. Fix fflags check so that the UFM
and URIO drivers work.
It is a bit unfortunate that the example to delete broken symlinks now uses
rm(1), but allowing this with -delete would require fixing fts(3) to not
imply FTS_NOCHDIR if FTS_LOGICAL is given (or hacks in the -delete option).

Extract the code to find and map the MADT ACPI table during early kernel
startup and genericize it so it can be reused to map other tables as well:
- Add a routine to walk a list of ACPI subtables such as those used in the
APIC and SRAT tables in the MI acpi(4) driver.
- Move the routines for mapping and unmapping an ACPI table as well as
mapping the RSDT or XSDT and searching for a table with a given signature
out into acpica_machdep.c for both amd64 and i386.
Split the 'video' ACPI lock up into two locks to resolve a LOR with the
sysctl lock. The 'video' lock now protects the 'bus' of video output
devices attached to a graphics adapter. It is used when iterating over
the list of outputs, etc. The 'video_output' lock is used to lock the
output-specific data similar to a driver lock for the individual video
outputs.
Extend the device pager to support different memory attributes on different
pages in an object.
- Add a new variant of d_mmap() currently called d_mmap2() which accepts
an additional in/out parameter that is the memory attribute to use for
the requested page.
- A driver either uses d_mmap() or d_mmap2() for all requests but not both.
The current implementation uses a flag in the cdevsw (D_MMAP2) to indicate
that the driver provides a d_mmap2() handler instead of d_mmap(). This
is done to make the change ABI compatible with existing drivers and
MFC'able to 7 and 8.
- Use the headers from ACPI-CA to define various constants and structures
for table layouts, etc. rather than homerolling our own structures and
constants in acpidump.h.
- Verify the extended checksum on the RSDP.
- Handle new ACPI 3.0 fields in MADT including X2APIC entries and
UIDs for local SAPICs.
- Add handling for new ACPI 3.0 flags in the FADT.

Random number generator initialization cleanup:
- Introduce new SI_SUB_RANDOM point in boot sequence to make it
clear from where one may start using random(9). It should be as
early as possible, so place it just after SI_SUB_CPU where we
have some randomness on most platforms via get_cyclecount().
- Move stack protector initialization to be after SI_SUB_RANDOM
as before this point we have no randomness at all. This fixes
stack protector to actually protect stack with some random guard
value instead of a well-known one.
Note that this patch doesn't try to address arc4random(9) issues.
With current code, it will be implicitly seeded by stack protector
and hence will get the same entropy as random(9). It will be
securely reseeded once /dev/random is feeded by some entropy from
userland.
