dd89bf7764 Use kdb_trap() rather than Debugger() to deal with unhandled undefined 
instructions in the kernel, so that DDB gets a useful trapframe.  Also
panic if this happens when DDB's not around.

41f83fd2b1 On a prefetch abort or an address exception in the kernel, drop 
straight into DDB rather than calling panic().  This will allow DDB to
see what was actually going on at the time of the exception.

142645a06a This file is dead. It has ceased to be. It has gone to meet it's maker. It 
is a late file.

Any rumours of it pining for the fjords are totally unsubstantiated.

ebc6dbad07 Define the mcount function in assembler, and have it save all registers 
used for argument passing, plus %rax (used to pass the number of float
arguments to varargs functions), to avoid having it clobber caller-saved
registers. mcount is emitted "under the radar", so the compiler doesn't
know it should do this.

Change the kernel mcount entry/exit macros to use plain cli/sti, like on i386.

85c506fb3b While NetBSD/sh5 has never needed a sigcode trampoline, other parts of 
the kernel seem to assume 'esigcode - sigcode' is non-zero.

ea56bcee84 Hide the register number constants behind an _R_ prefix, and also 
rename FPBASE to _FPBASE, so that we avoid polluting the user's
name space when e.g. <sys/ptrace.h> is included.  Previously, the
PC symbol in mips/regnum.h would conflict with the declaration of
the external variable by the same name in termcap.h, as discovered
by the ``okheaders'' regression test.

512e98364a I've been informed that any dependent targets on .BEGIN are 
ignored.  Fix the symlink creation for machine, mips, and pmax
accordingly.

Also, there's nothing .PHONY about the vers.c target, as far as I
can see, so I've removed that.

0cfca60cdf general_exception() now receives TEA as a third argument. For user 
mode EXPEVT_ADDR_ERR_{LD,ST} traps pass it as ksi_addr, also use it to
decide if this is a SIGBUS (unaliged access) or SIGSEGV (kernel VA
access).

Report EXPEVT_TLB_PROT_LD as SEGV_ACCERR, not SEGV_MAPERR.

While here, consistently use standard uint32_t instead of u_int32_t.

d8b0dd8a97 Create the "machine" and "arm" links directly from the .BEGIN rule, rather 
than in dependencies of it, since .BEGIN is apparently only special for
its commands, not its dependencies.  This should get boot26, and probably
boot32, compiling again.

94c8b6c69f Add _UC_SETSTACK, _UC_CLRSTACK flags. Add __fpr_fpul to __fpregset_t 
and redefine __fpr_regs as an array of 32 ints (SH3E has 16, SH4 has
32 32-bit FP registers) to reserve the space for FPU registers - we
will properly redefine this as a union when we do support FPU.
