#     powerpc/pseries: read the lpar name from the firmware
#     
#     The LPAR name may be changed after the LPAR has been started in the HMC.
#     In that case lparstat command is not reporting the updated value because
#     it reads it from the device tree which is read at boot time.
#     
#     However this value could be read from RTAS.
#     
#     Adding this value in the /proc/powerpc/lparcfg output allows to read the
#     updated value.
#     
#     However the hypervisor, like Qemu/KVM, may not support this RTAS
#     parameter. In that case the value reported in lparcfg is read from the
#     device tree and so is not updated accordingly.
