states. First its new name will be created causing it to have two
names (from possibly different parents). Next, if it has different
parents, its value of ".." will be changed from pointing to the old
parent to pointing to the new parent. Concurrently, its old name
will be removed bringing it back into a consistent state. When fsck
encounters an extra name for a directory, it offers to remove the
"extraneous hard link"; when it finds that the names have been
changed but the update to ".." has not happened, it offers to rewrite
".." to point at the correct parent. Both of these changes were
considered unexpected so would cause fsck in preen mode or fsck in
background mode to fail with the need to run fsck manually to fix
these problems.
This update changes these errors to be expected so that in preen
mode fsck will simply fix these transitional errors. For now,
background fsck will note these errors, but will need additional
kernel support to fix them, so will simply ignore them rather than
fail. A future update will allow background fsck to fix these
problems.

I/O port access is implemented on Itanium by reading and writing to a
special region in memory. To hide details and avoid misaligned memory
accesses, a process did I/O port reads and writes by making a MD system
call. There's one fatal problem with this approach: unprivileged access
was not being prevented. /dev/io serves that purpose on amd64/i386, so
employ it on ia64 as well. Use an ioctl for doing the actual I/O and
remove the sysarch(2) interface.
Backward compatibility is not being considered. The sysarch(2) approach
was added to support X11, but support for FreeBSD/ia64 was never fully
implemented in X11. Thus, nothing gets broken that didn't need more work
to begin with.

interrupt sources feeding into a hardintr anymore. The

libopie includes both <utmp.h> and <utmpx.h> in this case and uses some
#defines to let the code use struct utmpx and its utility functions.
We'd better not include <utmp.h> here, because maybe it will not be
present in the future.
Specifically, where locore had created large page mappings for the kernel,
the wrong vm page array entries were being initialized. The vm page array
entries for the pages containing the kernel were being initialized instead
of the vm page array entries for page table pages.

Make pmap_copy_page() L2-cache friendly by doing the copy through the
cacheable window on physical memory (KSEG0). On the Sibyte processor
going through the uncacheable window (KSEG1) bypasses both L1 and L2
caches so we may end up with stale contents in the L2 cache.
This also makes it consistent with the rest of the function that
uses cacheable mappings to copy pages.

I'm leaving it in its own directory rather than try to shoe-horn it
into the unrelated rmi directory. Its future location is an open

(u_int) is the wrong type here. Use unsigned long instead, even
though that's only less wrong...

Use unsigned long instead of unsigned for the integer casts here. The
former works for both ILP32 and LP64 programming models, while the
latter fails LP64.

Define __ELF_WORD_SIZE appropriately for n64. Note for N32 I believe
this is correct. While registers are 64-bit, n32 is a 32-bit ABI and
lives in a 32-bit world (with explicit 64-bit registers, however).
Change an 8, which was 4 + 4 or sizeof(int) + SZREG to be a simple '4
+ SZREG' to reflect the actual offset of the structure in question.

Does 4 things:
1) Adds future RMI directories
2) Places intr_machdep.c in specfic files.arch pointing to the generic
intr_machdep.c. This allows us to have an architecture dependant
intr_machdep.c (which we will need for RMI) in the machine specific
directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
may need to look at finding a better place to put this. But first I want to
get this thing compiling.
