From 3a64d5b82eccc0dc629d43cde791a2c19bd67dfc Mon Sep 17 00:00:00 2001 From: Kevin Brodsky Date: Thu, 18 Dec 2025 10:05:40 +0000 Subject: sparc/mm: export symbols for lazy_mmu_mode KUnit tests The lazy_mmu_mode KUnit tests call lazy_mmu_mode_{enable,disable}. These tests may be built as a module, and because of inlining this means that arch_{enter,flush,leave}_lazy_mmu_mode need to be exported.
