From 27a22fbdeedd6c5c451cf5f830d51782bf50c3a2 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 28 Oct 2019 09:08:34 +0000 Subject: arm64: Silence clang warning on mismatched value/register sizes Clang reports a warning on the __tlbi(aside1is, 0) macro expansion since the value size does not match the register size specified in the inline asm. Construct the ASID value using the __TLBI_VADDR() macro.
