[PATCH v2 0/5] cleanup error handling in kvmppc_read_int_cpu_dt()

[Daniel Henrique Barboza]

Hi,

In this second version the biggest change is that I decided to
error_fatal inside kvmppc_get_clockfreq().

After the discussions in v1 [1] it became clear that falling back to a
default value when 'clock-frequency' is missing is a bad idea. Not because
of the default value per se, but for the absence of this root node
property in the userspace.

This assumption works fine with pSeries, the most used KVM platform we
have today. If this change causes a legitimate regression (i.e. a valid
use case where clock-frequency is missing from the DT and it's ok) in
other KVM-capable ppc boards, we can amend it case by case.
