[PATCH 4.14 151/237] alpha: define get_cycles macro for arch-override

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

 



From: "Jason A. Donenfeld" <Jason@xxxxxxxxx>

commit 1097710bc9660e1e588cf2186a35db3d95c4d258 upstream.

Alpha defines a get_cycles() function, but it does not do the usual
`#define get_cycles get_cycles` dance, making it impossible for generic
code to see if an arch-specific function was defined. While the
get_cycles() ifdef is not currently used, the following timekeeping
patch in this series will depend on the macro existing (or not existing)
when defining random_get_entropy().
