From 53a563b01fa2ae2376a0b7d547f26a0ae9c78b5c Mon Sep 17 00:00:00 2001 From: Quentin Perret Date: Wed, 8 Dec 2021 15:22:56 +0000 Subject: [PATCH] KVM: arm64: Make the hyp memory pool static The hyp memory pool struct is sized to fit exactly the needs of the hypervisor stage-1 page-table allocator, so it is important it is not used for anything else. As it is currently used only from setup.c, reduce its visibility by marking it static.
