Pull percpu fix from Dennis Zhou:
"This is a fix for the first chunk size calculation where the variable
length array incorrectly used the number of longs instead of bytes of
longs.
This came in as a code fix and not a bug report, so I don't think it
was widely problematic. I believe it worked out due to it being
memblock memory and alignment requirements working in our favor"
