Having just seen a report of using "fips=1" on the kernel command line,
I could not find it documented anywhere, so add some help for it.

+ fips= Format: { 0 | 1}
+ Use to disable (0) or enable (1) FIPS mode.
+ If enabled, any process that is waiting on the
+ 'fips_fail_notif_chain' will be notified of fips
+ failures.
+ This setting can also be modified via sysctl at
+ /proc/sysctl/crypto/fips_enabled, i.e.,
+ crypto.fips_enabled.
+ If fips_enabled = 1, some crypto tests are skipped.
+ It can also effect which ECC curve is used.
+ If fips_enabled = 1 and a test fails, it will cause a
+ kernel panic.
+ If fips_enabled = 1, RSA test requires a key size of
+ 2K or larger.
