I think the issue lies in the start.S file. The MSR is getting
cleared before jumping out of the last 4k page to _start_cont, where
SRR1 (which is 0x0) gets written to the MSR.
Earlier the initialisation of the MSR was done in _start, which was
after the jump out of the last 4k page. Now the MSR value gets
overwritten on jumping out of the last page.
Is there any specific reason as to why the MSR initialisation is
moved in the last 4k page.
