History
Linus Torvalds 86a78a8b8d 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.
