Hello:

This series was applied to netdev/net-next.git (refs/heads/master):

This patch series uses the INDIRECT_CALL wrappers in some dst_ops
functions to mitigate retpoline costs. Benefits depend on the
platform as described below.

Background: The kernel rewrites the retpoline code at
__x86_indirect_thunk_r11 depending on the CPU's requirements.
The INDIRECT_CALL wrappers provide hints on possible targets and
save the retpoline overhead using a direct call in case the
target matches one of the hints.
