[PATCH] powerpc: Only calculate htab_size in one place for kexec
For kexec we need to know the size of the MMU hash table. Currently we calculate the size once in the htab code, and then twice more in the kexec code, once using htab_hash_mask and once using ppc64_pft_size. On some machines the ppc64_pft_size calculation is broken because ppc64_pft_size is not set. So we need to fix the second calculation, but better still we should just calculate the size once and use it everywhere else. Tested on Power5 LPAR, Power4 non-LPAR and Power3.
