The Freescale PAMU can be enabled on both 32 and 64-bit Power
chips. Commit 477ab7a19cec8409e4e2dd10e7348e4cac3c06e5
(iommu: Make more drivers depend on COMPILE_TEST)
restricted PAMU to PPC32. PPC covers both.

v2: Implemented Michael Ellerman's suggestion to clean
Failure to synchronize the PSL timebase currently prevents the
initialization of the cxl card, thus rendering the card useless. This
is too extreme for a feature which is rarely used, if at all.
This patch still tries to synchronize the PSL timebase when the card
is initialized, but doesn't fail i

The domain/PHB field of PCI addresses has its value obtained from a
global variable, incremented each time a new domain (represented by
struct pci_controller) is added on the system. The domain addition
process happens during boot or due to PCI device hotplug.
As recent kernels are using predictab

OK, I'm convinced.
New version of the patch out shortly.

"cpufreq: powernv: Remove cpu_to_chip_id() from hot-path" introduced
'core_to_chip_map' array to cache the chip-id of all cores. Replace
this with per_cpu variable that stores the pointer to the chip-array.
This removes the linear lookup and provides a neater and simpler

Thanks very much for the comments Gavin! I agree with all of them, will
rework the patch and send a new version.
