the canonical versions in kern_synch.c). Define __HAVE_BIGENDIAN_BITOPS
so the canonical versions will be used but will store priorities in the
desired (MSB) order for PowerPC (which allows the use of the cntlzw (count
leading zeroes, word) instruction in locore_subr.S to find the proper
priority).
- different set of device control registers.
- non-standard access to the time base.
- 16 byte cache lines.

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.
ppccalls, with system call numbers starting at 0x6000
fasttraps, with system call numbers starting at 0x7FF0
Because the Mach system call dispatching code has grown a bit
too much, introduce an inline function to handle it (mach_syscall_dispatch).
While we are there, remove the Mach and Linux includes from
arch/powerpc/powerpc/syscall.c and push them into
arch/powerpc/powerpc/{mach|linux}_syscall.c
moved to a Linux specific file, child_return is moved to trap.c,
and we introduce a EMULNAME macro co that syscall.c can be included to
define the system call handler for another emulation.
pmap_syncicache. This file uses a ppc feature in a sick and twisted way
to avoid mapping the physical pages used by those routines. It performs
the operations with the MMU disabled but PPC exception save and retstore
the machine state and are invoked with the MMU disabled, this doesn't have
an adverse effect on the system.
Currently only enable for MPC6xx and !OLDPMAP.
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.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h
Enforce -Wmissing-prototypes -Wstrict-prototypes for all ppc ports.
Split out macppc cpu support and make common to mpc6xx ports. Make
other mpc6xx ports use it. Add evcnts for mpc6xx traps.

IBM 4xx series CPU features:
- New pmap and revised trap handler.
- Support on-chip timers, PCI controller, UARTs
- Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
- Add in-kernel PPC floating point emulation
- New in{,4}_cksum that is between 1.5 and 5 times faster than the
old version depending on CPU type.
General changes:
- Kernel support for generic dbsym-style symbols.
