arch_timer_edge_cases hits the following assertion in < 10% of the test runs:
==== Test Assertion Failure ====
arm64/arch_timer_edge_cases.c:490: timer_get_cntct(timer) >= DEF_CNT + (timer_get_cntfrq() * (uint64_t)(delta_2_ms) / 1000)
pid=17110 tid=17110 errno=4 - Interrupted system call
1 0x0000000000404ec7: test_run at arch_timer_edge_cases.c:945
2 0x0000000000401fa3: main at arch_timer_edge_cases.c:1074

5 0x000000000040206f: _start at ??:?
timer_get_cntct(timer) >= DEF_CNT + msec_to_cycles(delta_2_ms)
Enabling the timer without proper xval initialization in set_tval_irq()
resulted in an early interrupt during timer reprogramming. Make sure
to set the xval before setting the enable bit.

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 reStructuredText 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.
