#     powerpc/mce: Avoid nmi_enter/exit in real mode on pseries hash
#     
#     Use of nmi_enter/exit in real mode handler causes the kernel to panic
#     and reboot on injecting SLB mutihit on pseries machine running in hash
#     MMU mode, because these calls try to accesses memory outside RMO
#     region in real mode handler where translation is disabled.
#     
#     Add check to not to use these calls on pseries machine running in hash
#     MMU mode.
#     
#     Fixes: 116ac378bb3f ("powerpc/64s: machine check interrupt update NMI accounting")
