From: Helge Deller <deller@gmx.de>

There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
target, e.g.:

- 32-bit HP-UX crashes on B160L (32-bit) machine
- NetBSD boot failure due to power button in page zero
- NetBSD FPU detection failure

This small patch series fixes those known regressions and
additionally:

- allows usage of the max. 3840MB of memory (instead of 3GB),
- adds support for the qemu --nodefaults option (to debug other devices)

I tried to keep the patches small to make backporting easier.

This patch set will not fix those known (non-regression) bugs:
- HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
- Linux kernel will still fail to boot on C3700 as long as kernel modules are used.

The whole series can be pulled from the "hppa-fixes-8.2" branch from:
https://github.com/hdeller/qemu-hppa.git        hppa-fixes-8.2

Please test and review.

I just pushed whole thing to debian, let's see...

Not commenting on anything yet, but this one just draw my attention:

This is quite a significant reduction in size, - more than 4 times.
Is that right?

Yes. I stripped the firmware binary to keep the mail overhead small.
The symbols are not needed as long as you don't do debugging, and
if you want to debug you better build the firmware yourself anyway.
