Tools used within the sandbox are now copied into the sandbox, see aosp/1531944. This caused the modified headers_install.sh, which is no longer installed, to point to a non-existent location. This change adds a level of indirection. The gen-headers_install.sh module no longer uses unifdef as a tool, but still modifies the headers_install.sh script, but not to point to a particular location, but to find the unifdef tool via an environment variable, LOC_UNIFDEF. Next, we modify qti_generate_kernel_headers_arm and qti_generate_kernel_headers_arm64 to need the unifdef tool (which is copied into the sandbox for these tools). We add a new --unifdef option to the kernel_headers.py script so that it can find the tool in the sandbox. The kernel_headers.py script sets the LOC_UNIFDEF environment variable before invoking the altered headers_install.sh script (also copied into the sandbox). Finally, we generate gen_headers_arm.bp and gen_headers_arm64.bp with all of these changes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
