Subject[PATCH v3 0/4] dirty_log_perf_test cpu pinning and some goodies
From
Pin vcpus to a host physical cpus in dirty_log_perf_test and optionally
pin the main application thread to a physical cpu if provided. All tests
based on perf_test_util framework can take advantage of it if needed.

While at it, I changed atoi() to atoi_paranoid() in other tests, sorted
command line options alphabetically, and made switch case logic of -e
option less error prone to code changes by adding break and decoupling
it from -g.

v3:
- Moved atoi_paranoid() to test_util.c and replaced all atoi() usage
with atoi_paranoid()
- Sorted command line options alphabetically.
- Instead of creating a vcpu thread on a specific pcpu the thread will
migrate to the provided pcpu after its creation.
- Decoupled -e and -g option.

v2: https://lore.kernel.org/lkml/20220819210737.763135-1-vipinsh@google.com/
- Removed -d option.
- One cpu list passed as option, cpus for vcpus, followed by
application thread cpu.
- Added paranoid cousin of atoi().
