bbcd53c960 drivers/char: remove /dev/kmem for good
Patch series "drivers/char: remove /dev/kmem for good".

Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and
memory ballooning, I started questioning the existence of /dev/kmem.

Comparing it with the /proc/kcore implementation, it does not seem to be
able to deal with things like

a) Pages unmapped from the direct mapping (e.g., to be used by secretmem)
  -> kern_addr_valid(). virt_addr_valid() is not sufficient.

b) Special cases like gart aperture memory that is not to be touched
  -> mem_pfn_is_ram()

Unless I am missing something, it's at least broken in some cases and might
fault/crash the machine.

Looks like its existence has been questioned before in 2005 and 2010 [1],
after ~11 additional years, it might make sense to revive the discussion.

CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by
mistake?).  All distributions disable it: in Ubuntu it has been disabled
for more than 10 years, in Debian since 2.6.31, in Fedora at least
starting with FC3, in RHEL starting with RHEL4, in SUSE starting from
15sp2, and OpenSUSE has it disabled as well.

1) /dev/kmem was popular for rootkits [2] before it got disabled
   basically everywhere. Ubuntu documents [3] "There is no modern user of
   /dev/kmem any more beyond attackers using it to load kernel rootkits.".
   RHEL documents in a BZ [5] "it served no practical purpose other than to
   serve as a potential security problem or to enable binary module drivers
   to access structures/functions they shouldn't be touching"

2) /proc/kcore is a decent interface to have a controlled way to read
   kernel memory for debugging puposes. (will need some extensions to
   deal with memory offlining/unplug, memory ballooning, and poisoned
   pages, though)

3) It might be useful for corner case debugging [1]. KDB/KGDB might be a
   better fit, especially, to write random memory; harder to shoot
   yourself into the foot.

4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems
   to be incompatible with 64bit [1]. For educational purposes,
   /proc/kcore might be used to monitor value updates -- or older
   kernels can be used.

5) It's broken on arm64, and therefore, completely disabled there.

Looks like it's essentially unused and has been replaced by better
suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's
just remove it.

   - Preparation to use devicetree for genpd
   - ti-sysc needs iorange check improved when the interconnect target
     module has no control registers listed
   - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to
     avoid issues with missing resources and unnecessary deferred probe
   - ti-sysc debug option can now detect more devices
   - ti-sysc now warns if an old incomplete devicetree data is found as
     we now rely on it being complete for am3 and 4
   - soc init code needs to check for prcm and prm nodes for omap4/5 and
     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4
   - omap5 clocks are missing gpmc and ocmc clock registers
   - pci-dra7xx now needs to use builtin_platform_driver instead of
     using builtin_platform_driver_probe for deferred probe to work

  Raspberry Pi:
   - Fix-up all RPi firmware drivers so as for unbind to happen in an
     orderly fashion
   - Support for RPi's PoE hat PWM bus

Defconfig changes for omaps for v5.13

Update defconfig to have nefilter available as loadable modules
to make the defconfig more usable for networked devices. And we now
select SIMPLE_PM_BUS so it can be dropped. And some devices use
EEPROM_AT25 so let's add it as a loadable module.

797e1491b8 ARM: configs: Remove REGULATOR_USERSPACE_CONSUMER
The userspace consumer is a development tool, not intended for producton
systems and so should not be present in defconfigs especially not those
for specific machines so is not a good fit for defconfig, remove it from
those defconfigs where it is enabled. No system in mainline actually
instantiates one.

   - tango - added in 2015, sporadic changes until 2017, but abandoned

   - u300 - added in 2009, no notable changes since 2013

   - zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes

   - arch/c6x - added in 2011, but work stalled soon after that

  A number of other platforms on the original list turned out to still
  have users. In some cases there are out-of-tree patches and users that
  plan to contribute them in the future, in other cases the code is
  complete and works reliably"

AT91 defconfig for 5.12, part 2:

367948220f module: remove EXPORT_UNUSED_SYMBOL*
EXPORT_UNUSED_SYMBOL* is not actually used anywhere.  Remove the
unused functionality as we generally just remove unused code anyway.

Add GPIO, SPI and I2C options that were missing from the
at91_dt_defconfig whereas they were in sama5_defconfig. It unifies all
AT91 defconfigs with same set of useful options.

c0b80a6247 ARM: configs: at91: DT/ATAG defconfig modifications
As all AT91 platforms are converted to DT for a long time, adapt the
defconfigs by:
- removing legacy CONFIG_ATAGS as a DT will always be provided;
- removing the CONFIG_ARM_APPENDED_DTB option on SAMA5 devices as the
  vast majority of systems will use a DT-aware bootloader on these
  devices.
