. Make this error a fatal build time error
. Move the support for dbsym into the MI Makefile.kern.inc,
conditional upon the SYMTAB_SPACE option being defined in
the kernel config file.
It cannot be compiled with -Wno-cast-qual due to a volatile pointer
being passed to memset(), and there's no easy way other than open-
coding memset() to fix this. So instead we cheat for now and add
-Wno-cast-qual to CFLAGS for this file. To be documented in doc/HACKS.
This makes it possible to define header files on the command line that
might include ${MACHINE} somewhere in the path. This might be used in
evbppc, for example, when defining PPC_PCI_MACHDEP_IMPL as, for example:
PPC_PCI_MACHDEP_IMPL="<arch/evbppc/sandpoint/pci_machdep.h>"
which will be included as
#include PPC_PCI_MACHDEP_IMPL
Prior to this change, the compile would fail trying to include
<arch/evbppc/1/pci_machdep.h>
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.
