are equal to PCCARD_TPCE_FS_MEMSPACE_NONE, memspace will be zero, so
testing for this case inside of the if statement results in dead code.
We'd fail to set a value to zero that's already zero (since it is
initialized to 0 indirectly) with this code being there. Well, except
in the very rare case that we have a card that has a defualt entry
that includes a memory space followed by one that has no memory space
(these are extremely rare, I don't recall ever having seen one :-).
Fix this by setting num_memspace to 0 in a more appropriate place.

actual support of the parts, just reporting what the part was.
Also, rename a few functins and symbols to reflect a more generic
part support that grew out of the early specific support.

soref() to also covering the update of so_state. While no other user
threads can update the socket state here as it's not yet hooked up to
the file descriptor array yet, the protocol could also frob the
socket state here, leading to a lost update to the so_state field.
No reported instances of this bug (as yet).

connection status before inserting the new socket into the listen
socket's accept queue, or there might be a race in which another thread
wakes up when the accept lock is released, and sees the socket before its
state is set correctly. The wakeup still occurs after the accept lock is
released. There have been no diagnoses of this bug in real-world systems
(as yet).

or just offering info. In the former case, we don't probe/attach to allow
the ACPI driver precedence. A refinement of this would be to actually
use the info provided by acpi_perf(4) to get the real CPU clock rates
instead of estimating them but since all systems that support both
acpi_perf(4) and ichss(4) export the control registers to acpi_perf(4),
it can just handle the registers on its own.
loaded, the tick interrupt enabled and a handler that resets the tick
counter on every tick interrupt. While this isn't documented this can
cause DELAY() to wait for a value the tick counter will not reach when
used in early boot, i.e. before cpu_initclocks() is called, depending
on when in the cycle DELAY() is called, the delay value and the value
the tick compare register is set to. The excessive use of DELAY() in
uart(4) when probing Sun keyboards seems to always manage to trigger
this, resulting in a hang during boot.
Disable the tick interrupt in tick_init(), which is called early in
sparc64_init(), until the interrupt is enabled again in tick_start(),
called by cpu_initclocks(), with our own handler. This fixes the hang
during probing Sun keyboards on AXi boards and Ultra 10, with other
machines like Ultra 5 probably being affected but not tested.

for now) exactly the same as KfAcquireSpinLock() and KfReleaseSpinLock().
I implemented the former as small routines in subr_ntoskrnl.c that just
turned around and invoked the latter. But I don't really need the wrapper
routines: I can just create an entries in the ntoskrnl func table that
map KeAcquireSpinLockRaiseToDpc() and KeReleaseSpinLock() to
KfAcquireSpinLock() and KfReleaseSpinLock() directly. This means
the stubs can go away.
close holes in detecting busfrees that occur after a packetized target
transitions to a non-packetized phase. The most common case where this
occurs is when a target is externally reset so the controller believes
a packetzied negotiation agreement is still in effect. Unfortunately,
disabling this feature seems to cause problems for the 7901B. Re-enable
ehanced busfree detection for this part until I can get my hands on a
samble to figure out if the old workaround is necessary and, if so, how
to make it work correctly.
This flag means "wait for all pending requests before returning to userland".
There are pending events for sure, because we just created new provider and
other classes want to taste it, but we cannot answer on I/O requests until
we're here.
