The kernel stack guard pages are only below the stack pointer, not above.
Remove unnecessary double-setting of the thread's onfault state in copyinstr().
Open Firmware mandates that certain cross-references, in particular those in /chosen, be ihandles. The ePAPR spec makes those cross-reference phandles, since FDT has no concept of ihandles. Have the OF FDT CI module interpret queries about ihandles as cross-reference phandles.
Real OF systems have an ihandle under /chosen/stdout, not a phandle. Use the right type.
Rearchitect platform memory map parsing to make it less Open Firmware-centric.
Remove fdtbus_bs_tag definition, which is now obsolete. The remainder of this file is also slated for future demolition.

r257991: Consolidate Apple firmware hacks and improve them by switching on the presence of mac-io devices in the tree, which uniquely identifies Apple hardware.
r257992: Allow OF_decode_addr() to also be able to map resources on big-endian devices. To this end, make PCI device detection rely on the device_type field rather than name, as per the standard.
r257993:
Make tsec work with the device tree present on the RB800. The previous code assumed that the MDIO bus was a direct child of the Ethernet interface. It may not be and indeed on many device trees is not. While here, add proper locking for MII transactions, which may be on a bus shared by several MACs.
r258504:
Save and restore the trap vectors when doing OF calls on pSeries machines.
It turned out that on pSeries machines the call into OF modified the trap vectors and this made further behaviour unpredictable.
With this commit I'm now able to boot multi user on a network booted environment on my IntelliStation 285. This is a POWER5+ machine.

Rework handling of ofw_quiesce(), making it the responsibility of the platform modules. Whether to call this function or not is highly machine dependent: on some systems, it is required, while on others it breaks everything. Platform modules are in a better position to figure this out. This is required for POWER hypervisor SCSI to work correctly. There are no functional changes on Powermac systems.

Allow Open Firmware syscons to attach to devices without an "address" property such as those found on some real and emulated IBM systems. The approach, which is taken from Linux, is to scan through the PCI bars until we find one large enough to contain the linear framebuffer and which is ideally prefetchable if no "address" property can be found. This makes the graphical console work with the pSeries target in QEMU.

Remove use of a separate ofw_pmap on 32-bit CPUs. Many Open Firmware mappings need to end up in the kernel anyway since the kernel begins executing in OF context. Separating them adds needless complexity, especially since the powerpc64 and mmu_oea64 code gave up on it a long time ago.
As a side effect, the PPC ofw_machdep code is no longer AIM-specific, so move it to powerpc/ofw.

Restructure how reset and poweroff are handled on PowerPC systems, since the existing code was very platform specific, and broken for SMP systems trying to reboot from KDB.
- Add a new PLATFORM_RESET() method to the platform KOBJ interface, and migrate existing reset functions into platform modules. - Modify the OF_reboot() routine to submit the request by hand to avoid the IPIs involved in the regular openfirmware() routine. This fixes reboot from KDB on SMP machines. - Move non-KDB reset and poweroff functions on the Powermac platform into the relevant power control drivers (cuda, pmu, smu), instead of using them through the Open Firmware backdoor. - Rename platform_chrp to platform_powermac since it has become increasingly Powermac specific. When we gain support for IBM systems, we will grow a new platform_chrp.

Fix a long-standing bug in the PowerPC OFW call function on SMP machines where running ofwdump could cause hangs by forcing all secondary CPUs into a busy wait with interrupts off during the call.
Following section 8.4 of the Open Firmware PowerPC processor binding, the firmware is free to overwrite the system interrupt handlers during OF calls, restoring the OS handlers on exit. On single CPU systems, this process is invisible to the operating system. On multiple CPU systems, taking any exception on a secondary CPU while an OF call is in progress ends with that exception vectored into OF, resulting in a slow movement of the entire system into firmware context and a machine hang.

On PowerMac11,2 and (presumably) PowerMac12,1, we need to quiesce the firmware in order to take over control of the SMU. Without doing this, the firmware background process doing fan control will run amok as we take over the system and crash the management chip.
This is limited to these two machines because our kernel is heavily dependent on firmware accesses, and so quiescing firmware can cause nasty problems.

Modularize the Open Firmware client interface to allow run-time switching of OFW access semantics, in order to allow future support for real-mode OF access and flattened device frees. OF client interface modules are implemented using KOBJ, in a similar way to the PPC PMAP modules.
Because we need Open Firmware to be available before mutexes can be used on sparc64, changes are also included to allow KOBJ to be used very early in the boot process by only using the mutex once we know it has been initialized.

On G5 systems, there are several otherwise standard PCI devices (Serverworks SATA) that will not allow their interrupt properties to be written, so this information must be supplied directly from Open Firmware.

Redefine bus_space_tag_t on PowerPC from a 32-bit integral to a pointer to struct bus_space. The structure contains function pointers that do the actual bus space access.
The reason for this change is that previously all bus space accesses were little endian (i.e. had an explicit byte-swap for multi-byte accesses), because all busses on Macs are little endian. The upcoming support for Book E, and in particular the E500 core, requires support for big-endian busses because all embedded peripherals are in the native byte-order.
With this change, there's no distinction between I/O port space and memory mapped I/O. PowerPC doesn't have I/O port space. Busses assign tags based on the byte-order only. For that purpose, two global structures exist (bs_be_tag and bs_le_tag), of which the address can be taken to get a valid tag.

o Move the prototype of mem_valid() from ofw_machdep.h to md_var.h. This avoids that mem.c has to include ofw_machdep.h, including all OFW related headers. o Provide a stub for OF_decode_addr(), which is used by low-level console drivers to obtain a tag and handle given a OFW phandle. This is different from sparc64, where a fake bus tag needs to be created explicitly.

Complete rework of the PowerPC pmap and a number of other bits in the early boot sequence.
The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors) which is 70% faster than the older code that the original pmap.c was based on. It has also been based on the framework established by jake's initial sparc64 pmap.c.
There is no change to how far the kernel gets (it makes it to the mountroot prompt in psim) but the new pmap code is a lot cleaner.
