are some Sun PCI devices around which bogusly set intpin to 0, although
they use the intline mechanism; this allows the device driver to correct
that.

bsd.lib.mk and thus broke the build since AFLAGS were not taken
into considered anymore, as bsd.lib.mk currently has wrong .s.o
rule that uses cc(1) instead of as(1).
Revision 1.14 reverted to using as(1), and revision 1.15 brought
AFLAGS back to the business, but revision 1.14 also broke "make
clean".
To fix this, but not break anything that was fixed in revisions
1.13-1.15, we revert mostly to revision 1.13 except for switching
back to using bsd.prog.mk. This gives us back the default .s.o
rule from sys.mk that uses as(1), and fixes "make clean" by
restoring the full contents of OBJS.
Also fixed LDFLAGS.

implementation of a largely MI pmap_object_init_pt() for vnode-backed
objects. pmap_enter_quick() is implemented via pmap_enter() on sparc64
and powerpc.
- Correct a mismatch between pmap_object_init_pt()'s prototype and its
various implementations. (I plan to keep pmap_object_init_pt() as
the MD hook for device-backed objects on i386 and amd64.)
- Correct an error in ia64's pmap_enter_quick() and adjust its interface
to match the other versions. Discussed with: marcel
bit in the EEPROM mode register on. Also, the address must be written
in two 32-bit register accesses instead of 6 8-bit accesses.
Tested with my 8139B cardbus NIC.

the user requests a read-only mount. This is necessary because we
don't do the VOP_OPEN again if they upgrade a read-only mount to
read-write.
Fixes lockup when creating files on msdosfs mounts that have been
mounted read-only then upgraded to read-write. The exact cause of
the lockup is not known, but it is likely to be the kernel getting
stuck in an infinite loop trying to write dirty buffers to a device
without write permission.

mapped I/O mode, we pause for .1 seconds after issuing the reset command
before trying to poll the 'command busy' bit in the status register.
With my 3c575C cardbus NIC, my Sony Picturebook locks up when it tries
to read the status register immediately after the reset. This appears
to be a problem only with certain NICs on certain hardware, but the
added delay should not hurt cards that already work.
This bug seems to have been brought to light by the fact that the xl
driver now defaults to memory mapped I/O mode instead of programmed
I/O mode like it used to. With PIO mode, the delay isn't needed and
everything works (which is why this NIC worked with 5.0-RELEASE but
not 5.1). I suspect that what's happening is that when the chip is
reset, it takes a little while for the memory-mapped decoding logic
to recover. Trying to access the chip's registers during this period
causes an error condition of some kind that wedges the system.
1.) Handle maximum segment sizes which are smaller than the IOMMU page
size by splitting up pages across multiple segments if needed; this case
was previously unimplemented, and would cause panics.
2.) KASSERT that the physical address is in range; remove a KASSERT that
has become pointless.
3.) Add a comment describing what remains to be fixed in the IOMMU code;
I plan to address these issues soon.

happens to work on 32-bit platforms as sizeof(long)=sizeof(int), but
wrecks all kinds of havoc (garbage reads, corrupting writes and
misaligned loads/stores) on 64-bit architectures.
The fix for now is to use fuword32() and suword32() and change the
type of the applicable int fields to int32. This is to make it
explicit that we depend on these fields being 32-bit. We may want
to revisit this later.

the VMIN and VTIME members of the c_cc array. These members are not
special control characters. By not excluding these members we
changed the noncanonical mode input processing when both members
were 0 on entry (=LINUX_POSIX_VDISABLE) as we would remap them to 255
(=_POSIX_VDISABLE). See termios(4) case A for how that screws up
your terminal I/O.
