ARM32 doesn't have instructions to do 64-bit/64-bit divisions. So, to implement the following instructions: BPF_ALU64 | BPF_DIV BPF_ALU64 | BPF_MOD BPF_ALU64 | BPF_SDIV BPF_ALU64 | BPF_SMOD We implement the above instructions by doing function calls to div64_u64() and div64_u64_rem() for unsigned division/mod and calls to div64_s64() for signed division/mod.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
