[PATCH 01/18] powerpc: Remove remaining iSeries chunks

[PATCH 01/18] powerpc: Remove remaining iSeries chunks

[Michael Ellerman]

In commit f5339277 "powerpc: Remove FW_FEATURE ISERIES from arch code", we
removed the bulk of the iSeries code, but missed a few bits.

Remove the mschunks bits, these were only ever used on iSeries as far as I
know, and are definitely not used anymore.

Make it even clearer that phys_to_abs() is a nop, by making it a macro. We
still have a few users of this, but should clean those up.

[PATCH 02/18] powerpc/crypto: Remove users of virt_to_abs() and phys_to_abs() in nx crypto driver

[Michael Ellerman]

phys_to_abs() is a nop, don't use it.

virt_to_abs() is just a wrapper around __pa(), call __pa() directly.

[PATCH 07/18] IB/ehca: Remove uses of virt_to_abs() and abs_to_virt()

[Michael Ellerman]

abs_to_virt() simply calls __va() and we'd like to get rid of it,
so replace all abs_to_virt() uses with __va().

__va() returns void *, so when assigning to a pointer there's no need
to cast.

Similarly virt_to_abs() just calls __pa().

[PATCH 09/18] ehea: Remove uses of virt_to_abs() and abs_to_virt()

[Michael Ellerman]

abs_to_virt() simply calls __va() and we'd like to get rid of it,
so replace all abs_to_virt() uses with __va().

Similarly virt_to_abs() just calls __pa().
