Use ifdef _KERNEL_OPT instead of ifdef _KERNEL before including
"opt_ppcarch.h".

Switch DDB for powerpc/booke into SOFTWARE_SSTEP.

SR_SINGLESTEP aka PSL_SE bit in MSR is only available for oea, and HW
debug facilities for booke are significantly different from oea.

Style and cosmetic changes. No binary changes intended.

Do not mask out LK bit (bit 31) from M_BCTR, which distinguishes
bcctr and bcctrl.

Fix build failure for ibm4xx kernels with GCC8.

update from HEAD

Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

    ARCH_ELFSIZE: the size for userland binaries
    KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.

Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.

closes kern/32359

Add a BKPT_ADDR() macro which gives MD code a chance to munge a
breakpoint address before it's used. Currently a no-op on all but sh5.

This is useful on sh5, for example, to mask off the instruction
type encoding in the bottom two address bits, and makes it possible
to do "db> break $rXX" instead of manually munging the address.

Make lint happy by not assigning to casted lvalue.

MPC601 support bits:
* install 601-specific DSI and RUNMODETRC trap handlers
* save/restore MQ in trapframe, add MQ hooks to DDB
* extend battable to 512 entries to hold the 601's 8M translations
* instead of adding I/O to BAT starvation, set up segment registers
  for Memory-Forced I/O Controller Interface Access
* sync after tlbie

Use Software Single Stepping for now when PPC_IBM4xx is defined. The
existing hardware assisted method doesn't work on this cpu.

Also correct the "I_B" constant in db_machine.h.

file db_machdep.h was added on branch nathanw_sa on 2002-01-08 00:27:10 +0000

Build for kgdb as well as for ddb (mutually exclusive).

Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.

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.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Apply patch (approved by jhawk and thorpej):

Rename VM_INHERIT_* to MAP_INHERIT_* and move them to sys/sys/mman.h as
discussed on tech-kern.
Retire sys/vm/vm_inherit.h, update man page for minherit(2).

The patch includes approximately the following diffs (approximately
since -current already used uvm/uvm_inherit.h):
minherit.2:	1.4 -> 1.8
mman.h:		1.26 -> 1.27
powerpc/include/db_machdep.h:	1.7 -> 1.8
pc532/include/db_machdep.h:	1.12 -> 1.13

uvm/uvm_inherit.h was removed.

<vm/vm_param.h> -> <uvm/uvm_param.h>

remove/move more mach vm header files:

	<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

<vm/vm_prot.h> becomes <uvm/uvm_prot.h>

vm_offset_t --> [pv]addr_t

Change db_expr_t from int to long like other ports.

Fix layout of powerpc_saved_state.

Import DDB from OpenBSD/powerpc.
