a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.
On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.
Move the trap/vector initialization for MPC6xx ports to mpc6xx_machdep.c
Also move softnet, install_extintr, mapiodev, kvtop. Add common BAT
initialization code.
Add user Altivec support.
Fix calls to OF_call_method in macppc/macppc/machdep.c.
Use ci_fpuproc in cpu_info instead of separate fpuproc.
Add separate syscall.c and defined __HAVE_SYSCALL_INTERN.
device drivers:
- Various native device entries in cdevsw/bdevsw.
- Rework the interrupt infrastructure to provide more flexibility to
the platform-dependent back-end. Rewrite the "ofwgen" simulated
interrupt routines to reflect the changes.
- Clear out the BAT registers and set the fixed battable entries before
calling the platform init routine. The platform init routine is allowed
to set entries in the battable.
- Don't call the platform cons_init routine until after translation is
enabled -- we might need translation to work in order to access bus
space.
