Since commit 9e2369c0 ("xen: add helpers to allocate unpopulated
memory") foreign mappings are using guest physical addresses allocated
via ZONE_DEVICE functionality.

This will result in problems for the case of no balloon memory hotplug
being configured, as the p2m list will only cover the initial memory
size of the domain. Any ZONE_DEVICE allocated address will be outside
the p2m range and thus a mapping can't be established with that memory
address.

Fix that by extending the p2m size for that case. At the same time add
a check for a to be created mapping to be within the p2m limits in
order to detect errors early.

While changing a comment, remove some 32-bit leftovers.

This is XSA-369.

Commit 3194a174 ("xen-netback: don't "handle" error by BUG()")
dropped respective a BUG_ON() without noticing that with this the
variable's value wouldn't be consumed anymore. With gnttab_set_map_op()
setting all status fields to a non-zero value, in case of an error no
slot should have a status of GNTST_okay (zero).

This is part of XSA-367.

Bailing immediately from set_foreign_p2m_mapping() upon a p2m updating
error leaves the full batch in an ambiguous state as far as the caller
is concerned. Instead flags respective slots as bad, unmapping what
was mapped there right away.

HYPERVISOR_grant_table_op()'s return value and the individual unmap
slots' status fields get used only for a one-time - there's not much we
can do in case of a failure.

Note that there's no GNTST_enomem or alike, so GNTST_general_error gets
used.

The map ops' handle fields get overwritten just to be on the safe side.

This is part of XSA-367.

 - Convert USB binding schemas to use graph schema and remove old plain
   text graph binding doc

 - Convert spi-nor and v3d GPU bindings to DT schema

 - Tree wide schema fixes for if/then schemas, array size constraints,
   and undocumented compatible strings in examples

Pull gpio updates from Bartosz Golaszewski:
 "It's been a relatively calm release cycle and we're actually removing
  more code than we're adding.

  Summary:

   - new driver for the Toshiba Visconti platform

   - rework of interrupt handling in gpio-tegra

   - updates for GPIO selftests: we're now using the character device to
     perform the subsystem checks

   - support for a new rcar variant + some code refactoring

   - refactoring of gpio-ep93xx

   - SPDX License identifier has been updated in the uapi header so that
     userspace programs bundling it can become fully REUSE-compliant

   - improvements to pwm handling in gpio-mvebu

   - support for interrupt handling and power management for gpio-xilinx
     as well as some code refactoring

   - support for a new chip variant in gpio-pca953x

   - removal of drivers: zte xs & intel-mid and removal of leftovers
     from intel-msic

   - impovements to intel drivers pulled from Andy Shevchenko

   - improvements to the gpio-aggregator virtual GPIO driver

   - and several minor tweaks and fixes to code and documentation all
     over the place"

Pull clk updates from Stephen Boyd:
 "This is all driver updates, the majority of which is a bunch of new
  Qualcomm clk drivers that dominate the diffstat because we add support
  for six SoCs from that particular vendor.

  The other big change is the removal of various clk drivers that are no
  longer used now that the kernel is dropping support for those SoCs.

  Beyond that there's the usual non-critical fixes for existing drivers
  and a good number of patches from Lee Jones that cleanup a bunch of
  W=1 enabled builds.

  Removed Drivers:
   - Remove efm32 clk driver
   - Remove tango4 clk driver
   - Remove zte zx clk driver
   - Remove sirf prima2/atlast clk drivers
   - Remove u300 clk driver

  New Drivers:
   - PLL support on MStar/SigmaStar ARMv7 SoCs
   - CPU clks for Qualcomm SDX55
   - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs
   - GCC clks for Qualcomm SM8350
   - GPU clks for Qualcomm SDM660/SDM630

  Updates:
   - Video clk fixups on Qualcomm SM8250
   - Improvements for multimedia clks on Qualcomm MSM8998
   - Fix many warnings with W=1 enabled builds under drivers/clk/
   - Support crystal load capacitance for Versaclock VC5

     glitches at boot
