From 942e89115b588b4b5df86930b5302a5c07b820ba Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 1 Oct 2020 12:42:41 +0000 Subject: powerpc/time: Avoid using get_tbl() and get_tbu() internally get_tbl() is confusing as it returns the content of TBL register on PPC32 but the concatenation of TBL and TBU on PPC64. Use mftb() instead. Do the same with get_tbu() for consistency allthough it's name is less confusing.
