From c5cf505446db70247a0beb5e70693a5f4754894d Mon Sep 17 00:00:00 2001 From: Alexander Egorenkov Date: Mon, 5 Jul 2021 19:33:27 +0200 Subject: [PATCH] s390/boot: move uv function declarations to boot/uv.h The functions adjust_to_uv_max() and uv_query_info() are used only in the decompressor. Therefore, move the function declarations from the global arch/s390/include/asm/uv.h to arch/s390/boot/uv.h.
