            Bug ID: 203571

            Status: NEW
          Severity: normal
          Priority: P1

          Assignee: platform_ppc-64@kernel-bugs.osdl.org

This patch optimizing chacha20 for WireGuard
https://github.com/shawnl/WireGuard/commit/3e02fce92a14cba7b7d1e2733def3a51bec97498

doesn't work because may_use_simd() is always returning false in kworkers. If I
remove the check everything seems to work fine.
