Catch the case where a synchronous exception occurs during the critical
...
section of another exception. This is likely to happen if the kernel
stack is misaligned, has dropped off the bottom of the PCB, or has
otherwise gone into orbit.
In this case, switch to a safe stack, save as much of the machine
state as possible and dump it to the console.

Another item on the TODO list:

Add support for cpus where sizeof(register_t) is not necessarily
the same as sizeof(void *). This is the case on SH5 using the
ILP32 ABI. On this cpu db_expr_t is, necessarily, 64-bits.
Unfortunately, in ILP32 mode, ddb will only display the low 32-bits
of any expression, including registers...

Also add an 84220-specific work-around for some braindamage (at least
in the PHY I'm working with) where the PHY always comes out of reset
isolated, regardless of the previous state of the BMCR_ISO bit. This
happens even if the PHY has address zero, which is contrary to the
part's datasheet...
The work-around is only applied if we notice BMCR_ISO is set when it
should be clear following reset. The fix is to wait 30mS and clear
it manually. (The change doesn't stick if it's cleared sooner than this)

Attach sm(4) at superio, instead of the previous isa bus attachment.

The latter's probe doesn't pick up the ethernet controller, and the

We attach it at superio mainly because they share the same region of
address space, and the ethernet controller's interrupt is routed
through the superio.

No longer use BTLB entries to map the entire address spaces of I/O subsystems,
...
since BTLB entries can be scarce and very little of an I/O subsystem normally
needs to be mapped.
Instead, the pmap now allows mappings of I/O space to be entered with
pmap_kenter_pa. bus_space mappings for small amounts of I/O space (as for
virtually all devices) are made this way, with BTLB entries still used for
large mappings for things like framebuffers.
This has led to more and cleaned-up uses of bus_space(9) and has caused
some autoconf cleanup. Also, kgdb is now attached and connected before
autoconfiguration, which is much earlier than before.

it at all call sites that have such a pointer readily available.

When we allocate a PTP, make sure the offset we specify is for

the 4M super-section that the PTP will map, not some random 1M
chunk of it. This gives the PTP hint code a much better chance
to working properly, and allows us to tidy up the code that
flushes a PTP from the cache in pmap_destroy().

Enable caching on kernel and user page tables. This saves having

to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).
We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).
