Do not attach JMicrons with single PCI function. They are not working as
AHCI for some reason, even when declaring so. Let atajmicron configure
them for us and provide PATA support.
Correct the information about the doceng@ team members - Murray Stokely
stepped down some time ago, about the same time as Giorgos Keramidas
joined the team.

Unroll copying of the registers in {g,s}et_mcontext() and limit it
to the set actually restored by tl0_ret() instead of using the whole
trapframe. Additionally skip %g7 as that register is used as the
userland TLS pointer.

Fix an obvious panic by not casting from a pointer that is 4-bytes
alignment to a type that needs 8-byte alignment, and thus causing
misaligned memory references.
o Align function on a 32-byte boundary so that the core's front-end
can deliver 2 bundles per cycle to the back-end.
o Mark syscall stubs with a special unwind ABI tag so that unwind
libraries know how to unwind.
Disable PortMultiplier Async Notifications for time of ports reset.
They are useless at that time, but confuse Marvell AHCI.
Add quirk for SiI57XX Port Multipliers, to hide extra port.
- Add some bits of HDMI/DisplayPort support from later specification updates.
It may be not enough to make them work, but at least should give some
information about these beasts.
- Add Realtek ALC887 codec ID.
Change the way in which AHCI+PATA combined controllers, such as JMicron
are handled. Instead of trying to attach two different drivers to
single device, wrapping each call, make one of them (atajmicron)
attach do device solely, but create child device for AHCI driver,
passing it all required resources. It is quite easy, as none of
resources are shared, except IRQ.
Add support for AHCI SATA parts of alike SATA+PATA MArvell controllers.
Add IDs of Marvell 88SX6102, 88SX6111. 88SX6141 controllers.
As result, it:
- makes drivers operation more independent and straitforward,
- allows to use new ahci(4) driver with such devices, adding support for
new features, such as PMP and NCQ, same time keeping legacy PATA support,
- will allow to just drop old ataahci driver, when it's time come.
- Remove most of direct relations between ATA(4) peripherial and controller
levels. It makes logic more transparent and is a mandatory step to wrap
ATA(4) controller level into ATA-native CAM SIM.
- Tune AHCI and SATA2 SiI drivers memory allocation a bit to allow bigger
I/O transaction sizes without additional cost.
- Add unit to the short month names for Japanese locales.
Without unit, the output of the application like ls(1)
is complicated.
- Since %b contains unit, %b is not suitable for c_fmt,
now. Use %_m instead.
Move inet_aton() (specular to inet_ntoa(), already present in libkern)
into libkern in order to made it usable by other modules than alias_proxy.

Introduce the new loader compile-time option BOOT_PROMPT_123 which allows
to enter the loader prompt just after entering the sequence "123".

- Add hw.clflush_disable loader tunable to avoid panic (trap 9) at
map_invalidate_cache_range() even if CPU is not Intel.
- This tunable can be set to -1 (default), 0 and 1. -1 is same as
current behavior, which automatically disable CLFLUSH on Intel CPUs
without CPUID_SS (should be occured on Xen only). You can specify 1
when this panic happened on non-Intel CPUs (such as AMD's). Because
disabling CLFLUSH may reduce performance, you can try with setting 0
on Intel CPUs without SS to use CLFLUSH feature.
- Amd64 init_secondary() calls initializecpu() while curthread is
still not properly set up. r199067 added the call to
TUNABLE_INT_FETCH() to initializecpu() that results in hang because
AP are started when kernel environment is already dynamic and thus
needs to acquire mutex, that is too early in AP start sequence to
work.
Extract the code that should be executed only once, because it sets
up global variables, from initializecpu() to initializecpucache(),
and call the later only from hammer_time() executed on BSP. Now,
TUNABLE_INT_FETCH() is done only once at BSP at the early boot
stage.
Correct some issues with zfs boot.
- Teach it to read gang blocks. (essentially untested)
If you see "ZFS: gang block detected!", please let
me know, so we can either remove the printf if it
works, or fix it if it doesn't.
- If multiple partitions exist on a disk, probe them all.
We also need to reset dsk->start to 0 to read the right
sector here.
- With GPT, we can have 128 partitions.
- If the bootfs property has ever been set on a pool
it seems that it never goes away. zpool won't allow
you to add to the pool with the bootfs property set.
However, if you clear the property back to default
we end up getting 0 for the object number and read
a bogus block pointer and fail to boot.
- Fix some error printfs. The printf in the loader is
only capable of c,s and u formats.
- Teach printf how to display %llu
