vmlinux.lds.h: Split ELF_DETAILS from STABS_DEBUG

2020-09-01T07:50:35+00:00

The .comment section doesn't belong in STABS_DEBUG. Split it out into a
new macro named ELF_DETAILS. This will gain other non-debug sections
that need to be accounted for when linking with --orphan-handling=warn.

kasan: stackdepot: move filter_irq_stacks() to stackdepot.c

2020-04-07T17:43:43+00:00

filter_irq_stacks() can be used by other tools (e.g.  KMSAN), so it needs
to be moved to a common location.  lib/stackdepot.c seems a good place, as
filter_irq_stacks() is usually applied to the output of
stack_trace_save().

This patch has been previously mailed as part of KMSAN RFC patch series.

vmlinux.lds.h: Replace RW_DATA_SECTION with RW_DATA

2019-11-04T14:57:41+00:00

Rename RW_DATA_SECTION to RW_DATA. (Calling this a "section" is a lie,
since it's multiple sections and section flags cannot be applied to
the macro.)

vmlinux.lds.h: Move NOTES into RO_DATA

2019-11-04T14:34:41+00:00

The .notes section should be non-executable read-only data. As such,
move it to the RO_DATA macro instead of being per-architecture defined.

nds32: linker script: GCOV kernel may refers data in __exit

2018-09-05T02:16:26+00:00

This patch is used to fix nds32 allmodconfig/allyesconfig build error
because GCOV kernel embeds counters in the kernel for each line
and a part of that embed in __exit text. So we need to keep the
EXIT_TEXT and EXIT_DATA  if CONFIG_GCOV_KERNEL=y.
