Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

Worth to pullup to both netbsd-8 and netbsd-9.

Note GENERIC kernel works on SL-C750/760/860 (and C1000/3x00) but for now
SL-C700 requires its own kernel with special KERNEL_BASE_PHYS address
