Catalin Marinas f4ea8e05f2 lkdtm/bugs: Do not confuse the clang/objtool with busy wait loop ... Since commit eb972eab07 ("lkdtm/bugs: Add cases for BUG and PANIC occurring in hardirq context"), building with clang for x86_64 results in the following warnings: vmlinux.o: warning: objtool: lkdtm_PANIC_IN_HARDIRQ(): unexpected end of section .text.lkdtm_PANIC_IN_HARDIRQ vmlinux.o: warning: objtool: lkdtm_BUG_IN_HARDIRQ(): unexpected end of section .text.lkdtm_BUG_IN_HARDIRQ caused by busy "while (wait_for_...);" loops. Add READ_ONCE() and cpu_relax() to better indicate the intention and avoid any unwanted compiler optimisations.
