switching.
- Add missing locking to ed_ifmedia_{upd,sts}().
- Canonicalize some messages.
- Based on actual functionality, ED_TC5299J_MII_DIROUT should be rather named
ED_TC5299J_MII_DIRIN.

Actually, text versions of generic commands are not used, since ngctl(8)
uses binary messages for them. And to request a text command one needs
a working ngctl(8). That's why the bug was never discovered. I'm pondering
on removing the text support for generic commands.

file as follows:
1. Common ia64-specific support functions have the ia64_ prefix.
2. Functions that work on physical cores have the phys_ prefix.
3. Functions that work on virtual cores have the virt_ prefix.
With that:
1. _kvm_kvatop() has been renamed to phys_kvatop() as it handles
physical cores only.
2. The new _kvm_kvatop() is nothing but a wrapper that calls either
phys_kvatop() or virt_kvatop() by virtue of the kvatop function
pointer in the vmstate structure.
3. virt_kvatop() is nothing but a wrapper around virt_addr2off().
4. virt_addr2off() iterates over the Phdrs to find the segment in
which the address falls and return the file offset for it.
Now it's up to the kernel to populate the core file appropriately.

Apple GCC has extensions to support for both label attributes and
an "unavailable" attribute. These are critical for objc but are
also useful in regular C/C++.
Apparently at least the label attributes might have found their way to
upstream GCC but the code doesn't seem available on the GPLv2 tree so
we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.

change virt_size(), virt_dumphdrs() and virt_dumpdata() into its callback
functions.
In virt_foreach() we iterate over all the virtual memory regions that we
want in the minidump. For now, just start with the PBVM (= kernel text
and data plus preloaded modules). The core file this produces can already
be used to work out the libkvm changes that need to be made to support it.
In parallel, we can flesh out the in-kernel bits to dump more of what we
need in a minidump without changing the core file structure.
This chip doesn't require the temperature sensor offset, either v1 or

Change the way that reservations keep track of which pages are in use.
Instead of using the page's PG_CACHED and PG_FREE flags, maintain a bit
vector within the reservation. This approach has a couple benefits.
First, it makes breaking reservations much cheaper because there are
fewer cache misses to identify the unused pages. Second, it is a pre-
requisite for supporting two or more reservation sizes.
to SIGTERM when ACPI is enabled. Sending SIGTERM to the hypervisor when an
ACPI-aware OS is running will now trigger a soft-off allowing for a graceful
shutdown of the guest.
- Move constants for ACPI-related registers to acpi.h.
- Implement an SMI_CMD register with commands to enable and disable ACPI.
Currently the only change when ACPI is enabled is to enable the virtual
power button via SIGTERM.
- Implement a fixed-feature power button when ACPI is enabled by asserting
PWRBTN_STS in PM1_EVT when SIGTERM is received.
- Add support for EVFILT_SIGNAL events to mevent.
- Implement support for the ACPI system command interrupt (SCI) and assert
it when needed based on the values in PM1_EVT. Mark the SCI as active-low
and level triggered in the MADT and MP Table.
- Mark PCI interrupts in the MP Table as active-low in addition to level
triggered.

The handler is now called after the register value is updated in the virtual

register virtualization turned on.
This also implies that we need to keep a snapshot of the last value written
to a LVT register. We can no longer rely on the LVT registers in the APIC
page to be "clean" because the guest can write anything to it before the
hypervisor has had a chance to sanitize it.

The handler is now called after the register value is updated in the virtual

We can no longer rely on the value of 'icr_timer' on the APIC page
in the callout handler. With APIC register virtualization the value of
'icr_timer' will be updated by the processor in guest-context before an
APIC-write VM-exit.
Clear the 'delivery status' bit in the ICRLO register in the write handler.
With APIC register virtualization the write happens in guest-context and
we cannot prevent a (buggy) guest from setting this bit.
