The following three patches should be low impact, and I think they could

Fix presentation of the slot number in the /sys/bus/pci/slots
directory to match that used in the majority of other drivers.

Do not wait for the pci slot status before reporting an error
to the device driver. Some systems may take many seconds to
report the slot status, and this can confuse unsuspecting
device drivers.

Hi,
This sounds like a familiar problem, but could not get answers in posts

One could make a strong argument to move all of this code
from kernel/rtas.c to platforms/pseries/setup.c I did not
do this, just so as to make the changes minimal.

The pseries hypervisor attempts to detect and prevent an
infinite loop of kernel crashes and auto-reboots. It does
so by refusing to auto-reboot unless we indicate that the
current boot was sucessful. So, indicate success late in
the boot sequence.

The following series of patches implement a basic framework
for hypervisor-assisted dump. The very first patch provides
documentation explaining what this is :-). Yes, its supposed
to be an improvement over kdump.
The patches mostly sort-of work; a list of open issues
is inculded in the
Basic documentation for hypervisor-assisted dump.

I'm seeing some funky behavior on power5/power6 partitions with this
patch.A /sbin/reboot is now behaving much more like a
/sbin/halt.
Anybody else seeing this, or is it

I'm guessing this worked up til now because the rtas_call function prototype
was telling compiler to cast these to 32-bit before passing them as args.
(and since these would still get passed as one arg per 64-bit reg, it
