Subject[RFC] hexagon: Drop the unused variable zero_page_mask
Date
Hexagon arch does not seem to have subscribed to _HAVE_COLOR_ZERO_PAGE
framework. Hence zero_page_mask variable is not needed.

I will have to request some one with hexagon system to compile and
test this patch. Dont have access to hardware.
