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
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
the active syscall description in struct lwp. To be used at some future
point to prevent unloading of modules that provide syscalls, while the
syscalls are in use.
screen:r1152x900x76 ) cut it off and pass it to the console driver. This
way radeonfb has a fighting chance to setup a mode similar or identical to
the firmware's.
to streaming buffers in each bus_dma functions on sbus/psycho layer.
Use iommu functions directly with storing the pointer into (unused)
_dm_cookie at bus_dmamap_create time.
positive answer in the list head, make sure to aquire pmap_lock before
traversing the pv list (and update the cache in head).
Fixes a diagnostic debugger call reported by Havard Eidnes.
of sections explicitly in the ldscript, so do not pass -n to ld.
This fixes the strange combined text/data sections seen with certain
(smaller) kernels as explained on tech-toolchain.

- use primary MMU context for consistency with other trap/interrupt handlers.
sparc64_ipi_save_fpstate, savefpstate:
- avoid storing fp registers as we can.
sparc64_ipi_save_fpstate, savefpstate, loadfpstate:
- remove unaligned case since buffers allocated with pool_cache are ensured
64-byte aligned.
