Move BOUNDED_SECTION_* macros to a new helper file: include/asm-generic/bounded_sections.lds.h and include it back into vmlinux.lds.h
This allows its reuse later to fix a future problem with modules failing to keep dyndbg sections in some circumstances. NB: this ignores a checkpatch warning, because new file is covered by GENERIC INCLUDE/ASM HEADER FILES CC: Arnd Bergmann <[email protected]> CC: [email protected] Signed-off-by: Jim Cromie <[email protected]> --- include/asm-generic/bounded_sections.lds.h | 38 ++++++++++++++++++++++++++++++ include/asm-generic/vmlinux.lds.h | 32 +------------------------ 2 files changed, 39 insertions(+), 31 deletions(-) diff --git a/include/asm-generic/bounded_sections.lds.h b/include/asm-generic/bounded_sections.lds.h new file mode 100644 index 000000000000..43e79603d4af --- /dev/null +++ b/include/asm-generic/bounded_sections.lds.h @@ -0,0 +1,38 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ + +#ifndef _ASM_GENERIC_BOUNDED_SECTIONS_H +#define _ASM_GENERIC_BOUNDED_SECTIONS_H + +#define BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_) \ + . = ALIGN(8); \ + _BEGIN_##_label_ = .; \ + KEEP(*(_sec_)) \ + _END_##_label_ = .; + +#define BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_) \ + . = ALIGN(8); \ + _label_##_BEGIN_ = .; \ + KEEP(*(_sec_)) \ + _label_##_END_ = .; + +#define BOUNDED_SECTION_BY(_sec_, _label_) \ + BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, __start, __stop) + +#define BOUNDED_SECTION(_sec) BOUNDED_SECTION_BY(_sec, _sec) + +#define HEADERED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_, _HDR_) \ + _HDR_##_label_ = .; \ + KEEP(*(.gnu.linkonce.##_sec_)) \ + BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_) + +#define HEADERED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_, _HDR_) \ + _label_##_HDR_ = .; \ + KEEP(*(.gnu.linkonce.##_sec_)) \ + BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_) + +#define HEADERED_SECTION_BY(_sec_, _label_) \ + HEADERED_SECTION_PRE_LABEL(_sec_, _label_, __start, __stop) + +#define HEADERED_SECTION(_sec) HEADERED_SECTION_BY(_sec, _sec) + +#endif /* _ASM_GENERIC_BOUNDED_SECTIONS_H */ diff --git a/include/asm-generic/vmlinux.lds.h b/include/asm-generic/vmlinux.lds.h index db38f52035f3..acb4aadd74da 100644 --- a/include/asm-generic/vmlinux.lds.h +++ b/include/asm-generic/vmlinux.lds.h @@ -211,37 +211,7 @@ # endif #endif -#define BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_) \ - . = ALIGN(8); \ - _BEGIN_##_label_ = .; \ - KEEP(*(_sec_)) \ - _END_##_label_ = .; - -#define BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_) \ - . = ALIGN(8); \ - _label_##_BEGIN_ = .; \ - KEEP(*(_sec_)) \ - _label_##_END_ = .; - -#define BOUNDED_SECTION_BY(_sec_, _label_) \ - BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, __start, __stop) - -#define BOUNDED_SECTION(_sec) BOUNDED_SECTION_BY(_sec, _sec) - -#define HEADERED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_, _HDR_) \ - _HDR_##_label_ = .; \ - KEEP(*(.gnu.linkonce.##_sec_)) \ - BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_) - -#define HEADERED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_, _HDR_) \ - _label_##_HDR_ = .; \ - KEEP(*(.gnu.linkonce.##_sec_)) \ - BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_) - -#define HEADERED_SECTION_BY(_sec_, _label_) \ - HEADERED_SECTION_PRE_LABEL(_sec_, _label_, __start, __stop) - -#define HEADERED_SECTION(_sec) HEADERED_SECTION_BY(_sec, _sec) +#include <asm-generic/bounded_sections.lds.h> #ifdef CONFIG_TRACE_BRANCH_PROFILING #define LIKELY_PROFILE() \ -- 2.53.0
