From a0e2bf7cb7006b5a58ee81f4da4fe575875f2781 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Thu, 11 Mar 2021 15:23:09 +0100 Subject: x86/paravirt: Switch time pvops functions to use static_call() The time pvops functions are the only ones left which might be used in 32-bit mode and which return a 64-bit value. Switch them to use the static_call() mechanism instead of pvops, as this allows quite some simplification of the pvops implementation.
