'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

Probably a bug. I use a temporary variable. I have not tested this

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

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.

Instead of mapping whole RAM with reserved TLB entries, map just enough
to ensure trap code will work (that is 0 upto ${endkernel}) and leave the
rest to pmap_tlbmiss(). Mapping whole physmem into the kernel wired way
too many TLB entries, see

http://mail-index.netbsd.org/port-powerpc/2006/10/27/0000.html

for performance analysis. While there, be a bit more descriptive in
pmap_tlbmiss() comment and use macro instead of numeric constant.

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

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.

Instead of mapping whole RAM with reserved TLB entries, map just enough
to ensure trap code will work (that is 0 upto ${endkernel}) and leave the
rest to pmap_tlbmiss(). Mapping whole physmem into the kernel wired way
too many TLB entries, see

http://mail-index.netbsd.org/port-powerpc/2006/10/27/0000.html

for performance analysis. While there, be a bit more descriptive in
pmap_tlbmiss() comment and use macro instead of numeric constant.

OK by Simon Burge

* convert ibm4xx-based evbppc from reserved-TLB entry allocation to recently
introduced ppc4xx_tlb_reserve() API.
* ibm405gp UART0 used to be linear mapped. The VA happens to be inside kernel
segment, giving us the possibility of multiple VA matches in the TLB. This
is considered "programming error" by 405 core and results in "undefined
behaviour". We now avoid mapping peripherals in kernel segment.
* Some boards used to map hardwired RAM size. We now use the real size as
passed in by boot firmware.
* don't call consinit() in obs2{00,66}_machdep.c because consinit() is already
called in ibm4xx_init() (but I'm not sure which place is good)

Do not call setroot() from MD code and from MI code, which has

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().
