code. The stack pointer was not adjusted, hence we were
overwriting the previous register value. But it looks like I
missed to check in the arch_cpu.h with the iframe structure
including the floating point registers anyway.
* Backported the ELF PPC relocation code from the boot loader to
the kernel.
* Fixed the PPC version of arch_thread_switch_kstack_and_call().
Apparently the signature had changed, but the assembly
implementation was not adjusted accordingly.
* sc prints more registers now (LR, CR, CTR, XER,...).
* Fixed several occurences of not-working fault handlers.
Apparently the compiler realized, that the "error" label was
never jumped to (by the code it knew), and optimized the
respective code away. Now we use a trick to make it think the
error label might actually be jumped to. I wonder whether the
x86 version has the same problem when being compiled with GCC4.
* Adopted the x86 page fault handling interrupt code.

in all drawing methods in case the parent window was
not in a "transaction" (fInTransaction). For ordinary
updates, nothing has changed, but if you call drawing
methods outside of an update, they will happen "immediately"
rather than when the link is sporadically full and auto
flushes. The effect is that the cursor in Terminal blinks
reliably, the selection in BTextViews follows the mouse
right on the spot (and so on). BWindow::BeginViewTransaction()
and EndViewTransaction() now have a meaning in Haiku too.

was not such a bad idea after all.
* Reenabled obscuring the cursor in ServerApp.

does in BeOS.
If you want it to wait until the shutdown process fails (or the system is actually
shut down), use the new "-s" option.

_DetermineTarget() is no longer called for these messages, "handler" will stay
NULL and the message will be dropped.

all in case the window doesn't have a current focus view.
That allows shortcuts like Command+q/w to work again.

it's Activate() method is called, if there is no
new focus app, the cursor is unhidden for safety. The
most notable difference: After having run a screen
saver, the cursor will be visible again.

* reworded Activate and commented out all code
that actually tries to change the cusor shape

context switches and all FPU registers in an iframe. We might want
to rethink this, though.
The kernel initialization runs to the end now. No boot volume is
found yet, but that is expected.

as well now, and makes quite a difference in Qemu.
Not tested for standard BViews, though.

too -- introduced a function ppc_kernel_thread_root() which calls the
three functions (entry, start, exit) in sequence. This brings us well
into the second part of the kernel initialization.
* Replaced stmw/lmw in ppc_context_switch() by individual stwu/lwzu
sequences. The former ones are documented to perform suboptimal on
some architecture implementations.

the previous implementation of arch_cpu_global_TLB_invalidate() back in
place (as fallback).

We don't do anything with it yet, though, so the BIOS will probably ignore us since
we are supposed to poll for events.

* Cloned iframe stack management from x86.
* Reimplemented arch_thread_{get,set}_current_thread(). The
thread structure is stored in SPRG2. It is set to NULL in
arch_cpu_preboot_init(), now. A non-null current thread
causes all kinds of undesired behavior in early boot code.
* We establish the address space mappings we know from the
Open Firmware as areas. At least those in kernel address
space. The ones in userland address space are tougher.
Fortunately on my Mac mini there aren't any save the
boot_loader stack, which is not needed any longer anyway.
* Added stack trace support to the kernel debugger. Mostly
cloned and adjusted the x86 code. Some bits are still
missing, like stack traces for other threads.
