[PATCH v4 0/4] ARM: Add support for CONFIG_DEBUG_VIRTUAL

[Florian Fainelli]

Hi all,

This patch series builds on top of Laura's [PATCHv5 00/10] CONFIG_DEBUG_VIRTUAL
for arm64 to add support for CONFIG_DEBUG_VIRTUAL for ARM.

This was tested on a Brahma B15 platform (ARMv7 + HIGHMEM + LPAE).

Note that the treewide changes would involve a huge CC list, which
is why it has been purposely trimmed to just focusing on the DEBUG_VIRTUAL
aspect.

Changes in v4:

- added Boris' ack for the first patch
- reworked the virtual address check based on Laura's suggestion to
  make the code more readable

Changes in v3:

- fix build failures reported by Kbuild test robot

Changes in v2:

- Modified MTD LART driver not to create symbol conflicts with
  KERNEL_START
- Fixed patch that defines and uses KERNEL_START/END
- Fixed __pa_symbol()'s definition
- Inline __pa_symbol() check wihtin the VIRTUAL_BUG_ON statement
- Simplified check for virtual addresses
- Added a tree-wide patch changing SMP/PM implementations to use
  __pa_symbol(), build tested against multi_v{5,7}_defconfig

Florian Fainelli (4):
  mtd: lart: Rename partition defines to be prefixed with PART_
  ARM: Define KERNEL_START and KERNEL_END
  ARM: Add support for CONFIG_DEBUG_VIRTUAL
  ARM: treewide: Replace uses of virt_to_phys with __pa_symbol
