clock past the End of Time.
If time_t is 32 bits, then the "End of Time" is Jan 18/19 2038
(depending on time zone).
This code copes with RTC's past the end of time if time_t is an int32
or less. It just forces the time back to 2037. This will let users
with screwed up clocks to at least boot and function long enough to
set their clocks to something sane.
This kludge is conditioned on an
if (sizeof(time_t) <= sizeof(int32_t))
which will automatically optimize the code out once we switch time_t
to a 64 bit quantity, which should happen well before 2037.
Patch based on code from Michael C. Richardson, with help from
Allen Briggs who pointed out a fencepost error.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
a struct device * corresponding to the ISA bus device. The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.
These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.
This should allow to use old X servers which depend on the old mouse
interface to work in the future.
XXX There can be only one attachment - either to an old console driver
or to the new pckbc driver - be configured.
null, the frstor would fault on a PPro. I'm pretty sure this is not
how the chip is supposed to behave, but it's easy enough to do a fninit
to throw away the exception state.
Also, some other minor changes to the documentation.
