Sometimes the KVM code on powerpc needs to emulate load or store
instructions from the guest, which can include both normal and byte
reversed forms.
We currently (AFAICT) handle this correctly, but some variable names are
very misleading. In particular we use "is_bigendian" in several places to

On POWER, storage caching is usually configured via the MMU - attributes
such as cache-inhibited are stored in the TLB and the hashed page table.
This makes correctly performing cache inhibited IO accesses awkward when
the MMU is turned off (real mode). Some CPU models provide special
registers t

The device tree now exposes the residency values for different idle states. Read
these values instead of calculating residency from the latency values. The
values
exposed in the DT are validated for optimal power efficiency. However to

compatibility with the older firmware code which doe
We currently read the information about idle states from the DT
so as to populate the cpuidle table. Use those APIs to read from
the DT that can avoid endianness conversions of the property values
in the cpuidle driver.

We currently read the information about idle states from the DT
so as to find out the cpu idle states supported by the platform.
Use those APIs to read from the DT that can avoid endianness

Moves clock state to struct clk_core, but takes care to change as little
API as
possible.

The wait parameter of call_usermodehelper() is not quite a parameter

So change its name to flags.
