[PATCH 0/4] Fix huge error for pow detected by Paul Zimmermann

This patch series fixes in pow the huge error detected by Paul
Zimmermann where x is negative and y is a large odd integer.

There is also an accuracy fix for cases where x is close to 1 and y is
large.

Andoni Arregi (4):
  Fix missing sign for overflow/underflow where x is negative and y is
    large odd integer
  Fix x close to 1, y between 2^31 and 2^64
  Compare j as unsigned
  Replace always true if with else
