[PATCH] powerpc/configs: Enable VMX crypto

From: Anton Blanchard <redacted>

We see big improvements with the VMX crypto functions (often 10x or more),
so enable it as a module.

Not in ppc64_defconfig?

Hi Steven,

Not in ppc64_defconfig?

Good point. The recent addition of powernv_defconfig made me forget
about ppc64_defconfig. We could do with some rationalisation here.

pseries isn't really pseries, perhaps we should call it ibm_defconfig,
or maybe server_deconfig. ppc64_defconfig continues to be the lower end
defconfig.

Understatement of the century.

pseries should be just pseries, and nothing else.

ppc64_defconfig continues to be the lower end defconfig.

ppc64_defconfig *should* be the primary config. And similarly ppc64le
when building little endian.

The reason being that 'make defconfig' will give you one of those
depending on uname (when building native).

I think the only thing disqualifying it from that role at the moment is
that it builds 4K pages.

But I think we should just change that. We can add ppc64_4K_defconfig
for anyone who wants it (G5 users mainly I would guess).

We'd also need to make sure ppc64/ppc64le have all the modern options
enabled.

cheers
