  powerpc/cacheinfo: Remove double free (2019-05-17 23:28:00 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.2 #2

One fix going back to stable, for a bug on 32-bit introduced when we added
support for THREAD_INFO_IN_TASK.

A fix for a typo in a recent rework of our hugetlb code that leads to crashes on
64-bit when using hugetlbfs with a 4K PAGE_SIZE.

Two fixes for our recent rework of the address layout on 64-bit hash CPUs, both
only triggered when userspace tries to access addresses outside the user or
kernel address ranges.

Finally a fix for a recently introduced double free in an error path in our
cacheinfo code.

Thanks to:
  Aneesh Kumar K.V, Christophe Leroy, Sachin Sant, Tobin C. Harding.
