A few changes to retrieve DAR and DSISR from struct regs
instead of retrieving them directly, as they may have
changed due to a TLB miss.
Also modifies hash_page() and friends to work with virtual
data addresses instead of physical ones. Same on load_up_fpu()
and load_up_altivec().

This patch results in qemu boot failures (mac99 with pmac32_defconfig).
Images fail silently; there is no console output. Reverting the patch
fixes the problem. Bisect log is attached below.
Assuming this was tested on real hardware, am I correct to assume that qemu
for ppc32 (more specifically, qemu's mac99 and g3beige machines) no longer
works with the upstream kernel ?
Before submitting the series, I successfully tested:
- Real HW with powerpc 8xx
- Real HW with powerpc 832x
- Qemu's mac99
I'll re-check the upstream kernel.
This is still working for me with the upstream kernel:
Interesting. What is your kernel configuration, your qemu version, and
your qemu command line ?
It works for me with CONFIG_VMAP_STACK=n, but not with pmac32_defconfig.
Thanks,
Guenter
