Subject[PATCH 4.14 150/237] parisc: define get_cycles macro for arch-override
From: "Jason A. Donenfeld" <>

commit 8865bbe6ba1120e67f72201b7003a16202cd42be upstream.

PA-RISC 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().
