Fred just pointed out that there is no register named FIR2 on PSL9 instead we have a FIR_MASK register in its place. So I will re-spin this patch with the correct register name.
Thanks everyone for the review and to Fred for pointing out the issue. -- Vaibhav Jain <vaib...@linux.vnet.ibm.com> Linux Technology Center, IBM India Pvt. Ltd.
