From 4a9eb94b5f1a1aeb2907952168605bcc9da1b4d3 Mon Sep 17 00:00:00 2001 From: Hannu Nyman Date: Sun, 28 May 2023 14:13:47 +0300 Subject: bpf-headers: fix compilation with LLVM_IAS=1 Linux 5.10.178 includes backported commits that break the compilation of bpf-headers, as the compilation gets confused which assembler to use. Caused by Linux upstream commits just before the .178 tag: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=v5.10.178 2023-04-20 kbuild: check CONFIG_AS_IS_LLVM instead of LLVM_IAS 2023-04-20 kbuild: Switch to 'f' variants of integrated assembler flag 2023-04-20 kbuild: check the minimum assembler version in Kconfig Explicitly use LLVM_IAS=1 to fix things.
