ENOENT when there's no PNP ID for this device node, or ENXIO when there
is one, but it doesn't match.
In the nonPNP case (as most Alpha systems appear to be), we were
treating the error return as an error, when it should be have ignored
it. Version 1.9 properly ignored it, but the attach re-write of 1.10
introduced this logic error.

update tick count for userland in thread_userret. This change
also removes a "no upcall owned" panic because fuword() schedules
an upcall under heavily loaded, and code assumes there is no upcall
can occur.

The removed argument could trivially be derived from the remaining one.
That in turn should be the same as curthread, but it is possible that curthread could be expensive to derive on some syste,s so leave it as an argument.
Having both proc and thread as an argumen tjust gives an opportunity for
them to get out sync.

causing panics for people who turn on DIAGNOSTIC, in what is otherwise

Bump configvers.h from 500013 to 600000.
Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device. This broke things like the snd_emu10k1 device, which required
quotes to make it parse right. The no-longer-needed quotes have been
removed from NOTES, GENERIC etc. eg, I've removed the quotes from:
device snd_maestro
device "snd_maestro3"
device snd_mss
I believe everything will still compile and work after this.
the old one is. Hence we need to evaluate the old one for _FDI since it
has a valid ACPI_HANDLE ivar. This is a minimal fix. Make a note that a
more complete one is to make fdc support the ACPI_HANDLE ivar for its
children.
This and the previous change are MT5 candidates.
time the interface counters were zeroed, currently the time if_attach()
was called. It is indentended to be a valid value for RFC2233's
ifCounterDiscontinuityTime and to make it easier for applications to
verify that the interface they find at a given index is the one that was
there last time they looked.
An if_epoch "compatability" macro has not been created as ifi_epoch has
never been a member of struct ifnet.

syscall can interrupt other thread's syscall in sleepq_catch_signals().
Current, all callers know thread_suspend_check may suspend thread
itself, so we need't to check return_instead for normal suspension
flags (no P_SINGLE_EXIT set).

do not set the virtual address to the bus address when the bus
doesn't have either of the PCI_RF_DENSE or PCI_RF_BWX flags set.
The TGA driver uses the virtual address to access the registers,
which on some machines can cause a memory management fault. Map
the bus address as K0SEG virtual memory instead. Note that with
some hardware combinations involving the TGA2 adapter this change
merely results that the memory management fault is replaced by a
machine check.
this in my tree for a while and in its disabled state there are no
issues. It isn't enabled yet because some drivers (in acpi) have side
effects in their probe routines that need to be resolved in some
manner before this can be turned on. The consensus at the last
developer's summit was to provide a static method for each driver
class that will return characteristics of the driver, one of which is
if can be reprobed idempotently.
address I've lost, that move the location information to the atttach
routine as well. While one could use devinfo to get this data, that
is difficult and error prone and subject to races for short lived
devices.
Would make a good MT5 candidate.
