[PATCH v4 02/16] x86/mtrr: remove unused cyrix_set_all() function
From: Juergen Gross
Date: Tue Oct 04 2022 - 04:12:18 EST
The Cyrix CPU specific MTRR function cyrix_set_all() will never be
called, as the struct mtrr_ops set_all() callback will only be called
in the use_intel() case, which would require the use_intel_if member
of struct mtrr_ops to be set, which isn't the case for Cyrix.
