weak aliases device_register(9) and device_register_post_config(9)
for the stub routine voidop(). Get rid of __HAVE_DEVICE_REGISTER and
__HAVE_DEVICE_REGISTER_POST_CONFIG.
for pci_chipset_tag_create() and pci_chipset_tag_destroy(). On
architectures that support it, an MI PCI bus driver can override the
architecture's default pci(9) and pci_intr(9) implementation.
Coming up next: documentation.
After that: x86 implementation.
Last but not least: make cbb(4) use MI PCI overrides.
bus_space_tag_create(9), and bus_space_tag_destroy(9). Use
bus_space_is_equal(9) throughout the kernel to compare
bus_space_tag_t's. Tested on i386 and on sparc64.
of transitions to IPL_HIGH from lower IPLs. SPLDEBUG is only available
on i386 and Xen kernels, today.
'options SPLDEBUG' adds instrumentation to spllower() and splraise() as
well as routines to start/stop debugging and to record IPL transitions:
spldebug_start(), spldebug_stop(), spldebug_raise(), spldebug_lower().
that can't happen as early as the other init functions as called from
cpu_startup() -- for example, register kauth(9) listeners.
Put unprivileged policy in the x86 code; used by i386, amd64, and xen.
into modules. By and large this commit:
- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:
- Inspecting process state requires thread context, so signals can no longer
be sent from a hardware interrupt handler. Signal activity must be
deferred to a soft interrupt or kthread.
- As the proc state locking is simplified, it's now safe to take exit()
and wait() out from under kernel_lock.
- The system spends less time at IPL_SCHED, and there is less lock activity.

Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
