2019-02-25 Thread Suraj Jitindar Singh
Implement support to allow KVM guests to take advantage of the large decrementer introduced on POWER9 cpus. To determine if the host can support the requested large decrementer size, we check it matches that specified in the ibm,dec-bits device-tree property. We also need to enable it in KVM by se
