scw 1d6e3e9f5a Check and clear the HT bit in strtc_clock_read(), not just strtc_clock_write()
otherwise we end up reading the date/time of the previous powerfail event.

briggs 1991e35ca9 PR kern/27088 from Jared Momose. The read function should specify the
length of the command buffer (1) instead of 0.  Otherwise, data will
have an implied offset of 0 and reads at non-0 locations will incorrectly
return the data from 0.  Fix as suggested in the report.

drochner 96b589fc18 a round of autoconf cleanup:
-convert submatch() style functions (passed to config_search() or
 config_found_sm()) to the locator passing variants
-pass interface attributes in some cases
-make submatch() functions look uniformly as far as possible
-avoid macros which just hide cfdata members, and reduce dependencies
 on "locators.h"

briggs e1aa8a2dd7 Handle the Halt Update Bit (HT), stored in the Alarm Hour register.
This bit will be set if the clock lost power (and may therefore
not have the correct time).  If this bit is set, the stored time
does not advance.  So, when setting the clock, if that bit is set,
we simply clear it.  It might be nice in some applications to pass
the information up a few layers if the bit is set when we read the
register initially.  For now, though, we ignore it.

jdolecek 372e5956ef Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
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.
