This patch maps vmap, IO and vmemap regions in the 0xc address range
instead of the current 0xd and 0xf range. This brings the mapping closer
to radix translation mode.
With hash 64K page size each of this region is 512TB whereas with 4K config
we are limitted by the max page table range of 64TB

Rather than relying on that we can pass an explict end_pos based on
the sizeof(vrsave). The result should be exactly the same but it's
more obviously not over-reading/writing the stack and it avoids the
compiler warning.
It works on my PowerMac G4 with Debian-ports unstable with gcc 8.

kmalloc() could fail, so insert a check of its return value. And
if it fails, returns -ENOMEM.
And remove (struct pstate_idx_revmap_data *) to fix coccinelle WARNING
by the way.
WARNING: casting value returned by memory allocation function to (struct
pstate_idx_revmap_data *) is useless.

Alternatively, the return type could be changed to bool, so that the
compiler does the right thing by itself.
