c2d3cf3653 selftests: filesystems: Fix incorrect kernel headers search path
Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).

1045a06724 remove CONFIG_ANDROID
The ANDROID config symbol is only used to guard the binder config
symbol and to inject completely random config changes.  Remove it
as it is obviously a bad idea.

6f9b5ed8ca Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
Here is the large set of char, misc, and other driver subsystem updates
 for 5.19-rc1.  The merge request for this has been delayed as I wanted
 to get lots of linux-next testing due to some late arrivals of changes
 for the habannalabs driver.
 
 Highlights of this merge are:
 	- habanalabs driver updates for new hardware types and fixes and
 	  other updates
 	- IIO driver tree merge which includes loads of new IIO drivers
 	  and cleanups and additions
 	- PHY driver tree merge with new drivers and small updates to
 	  existing ones
 	- interconnect driver tree merge with fixes and updates
 	- soundwire driver tree merge with some small fixes
 	- coresight driver tree merge with small fixes and updates
 	- mhi bus driver tree merge with lots of updates and new device
 	  support
 	- firmware driver updates
 	- fpga driver updates
 	- lkdtm driver updates (with a merge conflict, more on that
 	  below)
 	- extcon driver tree merge with small updates
 	- lots of other tiny driver updates and fixes and cleanups, full
 	  details in the shortlog.
 
 All of these have been in linux-next for almost 2 weeks with no reported
 problems.
 
 Note, there are 3 merge conflicts when merging this with your tree:
 	- MAINTAINERS, should be easy to resolve
 	- drivers/slimbus/qcom-ctrl.c, should be straightforward
 	  resolution
 	- drivers/misc/lkdtm/stackleak.c, not an easy resolution.  This
 	  has been noted in the linux-next tree for a while, and
 	  resolved there, here's a link to the resolution that Stephen
 	  came up with and that Kees says is correct:
 	  	https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
 
 I will be glad to provide a merge point that contains these resolutions
 if that makes things any easier for you.

75abec73de selftests: add binderfs selftests
This adds the promised selftest for binderfs. It will verify the following
things:
- binderfs mounting works
- binder device allocation works
- performing a binder ioctl() request through a binderfs device works
- binder device removal works
- binder-control removal fails
- binderfs unmounting works

The tests are performed both privileged and unprivileged. The latter
verifies that binderfs behaves correctly in user namespaces.
