This corrects the usage of the tlbie (TLB invalidate entry) instruction
in HV KVM. The tlbie instruction changed between PPC970 and POWER7.
On the PPC970, the bit to select large vs. small page is in the instruction,
not in the RB register value. This changes the code to use the correct
form on
The table of offsets to real-mode hcall handlers in book3s_hv_rmhandlers.S
can contain negative values, if some of the handlers end up before the
table in the vmlinux binary. Thus we need to use a sign-extending load
to read the values in the table rather than a zero-extending load.
Without this,

We want to use CMA for allocating hash page table and real mode area for
PPC64. Hence move DMA contiguous related changes into a seperate config
so that ppc64 can enable CMA without
