H A D | io_event_irq.c | a08a53ea Fri Apr 04 02:35:13 CDT 2014 Greg Kurz <gkurz@linux.vnet.ibm.com> powerpc/le: Enable RTAS events support
The current kernel code assumes big endian and parses RTAS events all wrong. The most visible effect is that we cannot honor EPOW events, meaning, for example, we cannot shut down a guest properly from the hypervisor.
This new patch is largely inspired by Nathan's work: we get rid of all the bit fields in the RTAS event structures (even the unused ones, for consistency). We also introduce endian safe accessors for the fields used by the kernel (trivial rtas_error_type() accessor added for consistency).
