powerpc: pseries: Fix kexec on machines with more than 4TB of RAM commit bed9a31527af8ff3dfbad62a1a42815cef4baab7 upstream. On a box with 8TB of RAM the MMU hashtable is 64GB in size. That means we have 4G PTEs. pSeries_lpar_hptab_clear was using a signed int to store the index which will overflow at 2G.
