Especially since this is broken for Little Endian !
Neelesh, please make sure you test your patch on LE.

We have a bug in our hugepage handling which exhibits as an infinite
loop of hash faults. If the fault is being taken in the kernel it will
typically trigger the softlockup detector, or the RCU stall detector.
The bug is as follows:
1. mmap(0xa000, ..., MAP_FIXED | MAP_HUGE_TLB | MAP_ANONYMO
T4240RDB board Specification
Memory subsystem:
6GB DDR3
128MB NOR flash
2GB NAND flash
Ethernet:
Eight 1G SGMII ports
Four 10Gbps SFP+ ports
PCIe:
Two PCIe slots
USB:
Two USB2.0 Type A ports
SDHC:
One SD-card port
SATA:
One S
T4240QDS and T4240RDB have the third DMA engine
controller. So add corresponding DMA node into
dts file.

We are seeing a lot of PMU warnings on POWER8:
Can't find PMC that caused IRQ
Looking closer, the active PMC is 0 at this point and we took a PMU
exception on the transition from negative to 0. Some versions of POWER8
have an issue where they edge detect and not level detect PMC overflows.
