This patchset aims to fix potential integer overflows reported
by Coverity.
In all cases the potential overflowing expressions are evaluated
using 32-bit arithmetic before being used in contexts that expect
a 64-bit arithmetic. So a cast to the proper type was added to each
of those expressions in order to avoid any potential integer overflow.
This also gives the compiler complete information about the proper
arithmetic for each expression and improves code quality.
Addresses the following Coverity IDs reported as
"Unintentional integer overflow" issues:
200604, 1056807, 1056808, 1271223,
1324146, 1392628, 1392630, 1446589,
1454996, 1458347.
