remove (db_addr_t) cast in sh3 PC_REGS(regs) definition.

Fixes KGDB build option for SH3/4 code.

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.

Introduce DDB_EXPR_FMT and replace the logic around DB_EXPR_T_IS_QUAD.

Retire struct user, remove sys/user.h inclusions.  Note sys/user.h header
as obsolete.  Remove USER_TO_UAREA/UAREA_TO_USER macros.

Fix IS_BREAKPOINT_TRAP: EXP_BREAK is not a breakpoint trap, it's UBC
(user break controller) trap, and we use UBC for single-stepping, not
for ddb breakpoints.  ddb breakpoints are "trapa 0xc3".

- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.

Replace the Mach-derived boolean_t type with the C99 bool type.  A
future commit will replace use of TRUE and FALSE with true and false.

closes: PR kern/32359

modifies machine/db_machdep.h: BKPT_SET(inst) to BKPT_SET(inst, addr) for all archs ie; passess the
breakpoint address as well.

Patch from cherry@mahiti.org

Declare ddb_regs extern in db_machdep.h and provide the defintion in
db_interface.c.

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.

catch up with -current on kqueue branch

rework general exception, and TLB exception handling for new pmap.
all exception staffs are moved to exception.[ch]

file db_machdep.h was added on branch nathanw_sa on 2002-05-09 12:24:21 +0000

rework general exception, and TLB exception handling for new pmap.
all exception staffs are moved to exception.[ch]

Use "#define<tab>", white space nits.

cosmetic changes, fix comments.

Catch up with -current.

Initial support for KGDB on the sh3.

TLB dump command added to DDB

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.

DDB single step and stack trace support.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
	As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
