The VCPUOP_register_runstate_memory_area hypercall is still actively
used, e.g., in the Linux arm64 codebase. When KPTI is enabled, the area
was not registered from the beginning due to the VA not always being
valid. In such cases, Linux falls back to using the standard PV time
interface (ARM DEN 0
This is preparatory work for the upcoming commits that implement the
standard PV time interface (ARM DEN 0057A).
No functional changes intended.

Even though make_hypervisor_node() does not rely on the /reserved-memory
instantiation when calling find_unused_regions() (the wrapper introduced
in the previous commit), the next but one commit will use it for PV time
shared regions, in addition to the existing extended regions.

The /reserved-memory node is inherently not specific to static-shmem. In
the next commit, child nodes will be added under /reserved-memory for
the stolen time shared memory regions.

This series proposes the standard PV time implementation as per ARM DEN 0057A.
The first three commits are preparatory work, where no functional changes are
intended.

Dashes were wrongly not translated into underscores, thus generating

Hi all,
I managed to get past the kernel panic (sort of) by doing the following:
1) Ensure system is fully OFF before booting. A reset/reboot will cause these
errors.
2) Fix the BIOS config to ensure the PCI-ports are split correctly. If anyone
has a Supermicro board and gets errors about PCI-
When a running unit is about to be scheduled out due to a competing unit
with the highest remaining credit, the residual credit of the previous
unit is currently ignored in csched2_runtime() because it hasn't yet
been reinserted into the runqueue.
As a result, two equally weighted, busy units can
