Andrii Nakryiko a7c1eb9cb8 selftests/bpf: make test_align selftest more robust 
[ Upstream commit 4f999b7677 ]

test_align selftest relies on BPF verifier log emitting register states
for specific instructions in expected format. Unfortunately, BPF
verifier precision backtracking log interferes with such expectations.
And instruction on which precision propagation happens sometimes don't
output full expected register states. This does indeed look like
something to be improved in BPF verifier, but is beyond the scope of
this patch set.

So to make test_align a bit more robust, inject few dummy R4 = R5
instructions which capture desired state of R5 and won't have precision
tracking logs on them. This fixes tests until we can improve BPF
verifier output in the presence of precision tracking.

README 

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.
