[RESEND PATCH v6 0/4] devres: provide and use devm_kstrdup_const()

[Bartosz Golaszewski <brgl@bgdev.pl>]

Hi Greg,

this has been reviewed a lot and three first patches can be picked
up. Please take it through your tree.

This series implements devm_kstrdup_const() together with some
prerequisite changes and uses it in tegra-hsp driver.

v1 -> v2:
- fixed the changelog in the patch implementing devm_kstrdup_const()
- fixed the kernel doc
- moved is_kernel_rodata() to asm-generic/sections.h
- fixed constness

v2 -> v3:
- rebased on top of 4.19-rc5 as there were some conflicts in the
  pmc-atom driver
- collected Reviewed-by tags

v3 -> v4:
- Andy NAK'ed patch 4/4 so I added a different example
- collected more tags

v4 -> v5:
- instead of providing devm_kfree_const(), make devm_kfree() check if
  given pointer is not in .rodata and act accordingly

v5 -> v6:
- fixed the commit message in patch 2/4 (s/devm_kfree_const/devm_kfree/)
- collected even more tags
