Some code churn:
o Eliminate IA64_PHYS_TO_RR6 and change all places where the macro is used
by calling either bus_space_map() or pmap_mapdev().
o Implement bus_space_map() in terms of pmap_mapdev() and implement
bus_space_unmap() in terms of pmap_unmapdev().
o Have ia64_pib hold the uncached virtual address of the processor interrupt
block throughout the kernel's life and access the elements of the PIB
through this structure pointer.
This is a non-functional change with the exception of using ia64_ld1() and
ia64_st8() to write to the PIB. We were still using assignments, for which
the compiler generates semaphore reads -- which cause undefined behaviour
for uncacheable memory. Note also that the memory barriers in ipi_send() are
critical for proper functioning.
With all the mapping of uncached memory done by pmap_mapdev(), we can keep
track of the translations and wire them in the CPU. This then eliminates
the need to reserve a whole region for uncached I/O and it eliminates
translation traps for device I/O accesses.

When growing a UFS1 filesystem, we need to initialise all inodes in any new
cylinder groups that are created. When the filesystem is first created,
newfs always initialises the first two blocks of inodes, and then in the
UFS1 case will also initialise the remaining inode blocks. The changes in
growfs.c 1.23 broke the initialisation of all inodes, seemingly based on
this implementation detail in newfs(8). The result was that instead of
initialising all inodes, we would actually end up initialising all but the
first two blocks of inodes. If the filesystem was grown into empty
(all-zeros) space then the resulting filesystem was fine, however when
grown onto non-zeroed space the filesystem produced would appear to have
massive corruption on the first fsck after growing.
A test case for this problem can be found in the PR audit trail.
Fix this by once again initialising all inodes in the UFS1 case.

acpi cpu: probe+attach before all other enumerated children on acpi bus
Some current systems dynamically load SSDT(s) when _PDC/_OSC method
of Processor is evaluated. Other devices in ACPI namespace may access
objects defined in the dynamic SSDT. Drivers for such devices might
have to have a rather high priority, because of other dependencies.
Good example is acpi_ec driver for EC.
Thus we attach to Processors as early as possible to load the SSDTs
before any other drivers may try to evaluate control methods.
It also seems to be a natural order for a processor in a device
hierarchy.
On the other hand, some child devices on acpi cpu bus need to access
other system resources like PCI configuration space of chipset devices,
so they need to be probed and attached rather late.
For this reason we probe and attach the cpu bus at
SI_SUB_CONFIGURE:SI_ORDER_MIDDLE SYSINIT level.
In the future this could be done more elegantly via multipass.
Please note that acpi drivers that might access ACPI namespace from
device_identify will do that before _PDC/_OSC of Processors are evaluated.
