# Replace relaswap with built-in one, because relaswap # does a simple byte to byte swap. # # Since Spectre mitigations have made indirect function calls more # expensive, and the default simple byte copies swap is implemented # without them, an "optimized" custom swap function is now # a waste of time as well as code. # # Signed-off-by: Andrey Abramov # Reviewed by: George Spelvin # Acked-by: Michael Ellerman (powerpc) # Link: https://lore.kernel.org/r/994931554238042@iva8-b333b7f98ab0.qloud-c.yandex.net #
