"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
from devices connected to pckbc:
- Do actual sample collection in pckbc.
- Add rndsource_element_t to the slot data.
- Change pckbc_set_inputhandler() to take an additional argument,
the name of the device, which is (eventually) passed into
rnd_attach_source() to identify the source.
- Change callers of pckbc_set_inputhander() appropriately.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
tsleep() to be called from an interrupt handler.
The semantics of the scroll-lock key is changed now: it issues a ^S or
^Q, depending on the current state. (It should probably issue
tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more
serious structural changes because there is not always a tty context
present.)
The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it
will show the real state even if the start/stop characters are remapped
or the normal ^S/^Q are used.
keys on a pccons console keyboard.

Note that I only did this for the US type keyboard maps.
This and all other such options should be documented, and perhaps
rennamed with consistant PCCONS_ prefixes.
o option DISPLAY_ISO8859 enables the display of iso-latin1
character set (instead of the IBM page code 437)
o option FRENCH_KBD, GERMAN_KBD or NORVEGIAN_KBD implement
support for national keyboards (implies DISPLAY_ISO8859).

2) Add option PCCONS_REAL_BS which (for US keyboards only) forces
backspace to really be backspace and not delete. Intended to close
PR #2264 submitted by Greg Woods. He wanted it changed for everyone
-- I thought adding a kernel compile option was friendlier.
Note: Both of these sets of options really should be documented in an
i386 specific version of options(4).
