From c03e27506a564ec7db1b179e7464835901f49751 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 29 Mar 2019 17:47:35 -0700 Subject: x86/asm: Mark all top level asm statements as .text With gcc toplevel assembler statements that do not mark themselves as .text may end up in other sections. This causes LTO boot crashes because various assembler statements ended up in the middle of the initcall section. It's also a latent problem without LTO, although it's currently not known to cause any real problems. According to the gcc team it's expected behavior. Always mark all the top level assembler statements as text so that they switch to the right section.
