Subject: [PATCH 0/2] powerpc: Fix integer underflow & leak

Hi,

This series fixes integer overflow & leak problem. I noticed this problem
when Gautam reported a kernel bug with another patch series of mine:
https://lore.kernel.org/linuxppc-dev/aH9Na8ZqrI0jPhtl@li-c6426e4c-27cf-11b2-a85c-95d65bc0de0e.ibm.com/

The root cause of that report is a bug in that series. However, that bug
triggered another existing bug, causing the reported end results.
