vmlinux.lds.h: Fix incomplete .text.exit discards

2018-10-11T21:54:58+00:00

Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM:

  `.text.exit' referenced in section `.ARM.exidx.text.exit':
  defined in discarded section `.text.exit'

  `.text.exit' referenced in section `.fini_array.00100':
  defined in discarded section `.text.exit'

And related errors on NDS32:

  `.text.exit' referenced in section `.dtors.65435':
  defined in discarded section `.text.exit'

The gcov compiler flags cause certain compiler versions to generate
additional destructor-related sections that are not yet handled by the
linker script, resulting in references between discarded and
non-discarded sections.

Since destructors are not used in the Linux kernel, fix this by
discarding these additional sections.

ARM: 8774/1: remove no-op macro VMLINUX_SYMBOL()

2018-05-19T10:53:46+00:00

VMLINUX_SYMBOL() is no-op unless CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX
is defined.  It has ever been selected only by BLACKFIN and METAG.
VMLINUX_SYMBOL() is unneeded for ARM-specific code.

ARM: simplify and fix linker script for TCM

2018-03-10T01:20:43+00:00

Let's put the TCM stuff in the __init section directly. No need for
a separately freed memory area.

Remove redundant linker sections, as well as comments that were more
confusing than no comments at all. Finally make it XIP compatible by
using LOAD_OFFSET in the section LMA specification.

ARM: linker script: factor out TCM bits

2018-03-10T01:20:22+00:00

This is a plain move with identical results, and therefore
still broken in the XIP case.

ARM: linker script: factor out stuff for the .text section

Move common entries to vmlinux.lds.h as ARM_TEXT.

ARM: linker script: factor out stuff for the DISCARD section

2018-03-10T01:19:35+00:00

Move common entries to vmlinux.lds.h and leave XIP and non-XIP entries
in their respective file. The ARM_NOMMU_KEEP() and ARM_NOMMU_DISCARD()
macros are added to be usable within the definition of ARM_DISCARD macro.

ARM: linker script: factor out some common definitions between XIP and non-XIP

2018-03-10T01:19:01+00:00

Lots of duplications between vmlinux.lds.S and vmlinux-xip.lds.S.
This may lead to one file being updated but not the other. For example,
SOFTIRQENTRY_TEXT and HYPERVISOR_TEXT were missing from the XIP version.

This creates vmlinux.lds.h where a bunch of common defines are moved.
