[RFC PATCH v2 4/9] alpha: avoid using on_each_cpu hard coded ret value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

on_each_cpu always returns a hard coded return code of zero.

Removing all tests based on this return value saves run time
cycles for compares and code bloat for branches.
