[Qemu-devel] [PATCH] ppc: abort if compat property contains an unknown value

[Greg Kurz]

It is not possible to set the compat property to an unknown value with
powerpc_set_compat(). Something must have gone terribly wrong in QEMU,
if we detect an "Internal error" in powerpc_get_compat(). Let's abort then.

This patch also drops the "max_compat ? *max_compat : -1" construct. It is
useless since max_compat is dereferenced a few lines above.
