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.

My only nit would be that in general for consistency with other function names
_RTAS_ and _DT_ should be lowercase. Seeing as they are statically scoped within
lparcfg.c maybe its ok. Otherwise,

Yeah I agree, I changed them to lower case when applying.
