[PATCH v2] powerpc/pseries/vas: Ignore VAS update for DLPAR if copy/paste is not enabled

2023-03-20 Thread Haren Myneni
The hypervisor supports user-mode NX from Power10. pseries_vas_dlpar_cpu() is called from lparcfg_write() to update VAS windows for DLPAR event in shared processor mode and the kernel gets -ENOTSUPP for HCALLs if the user-mode NX is not supported. The current VAS implementation also supports
