#     powerpc/security: Fix spectre_v2 reporting
#     
#     When I updated the spectre_v2 reporting to handle software count cache
#     flush I got the logic wrong when there's no software count cache
#     enabled at all.
#     
#     The result is that on systems with the software count cache flush
#     disabled we print:
#     
#       Mitigation: Indirect branch cache disabled, Software count cache flush
#     
#     Which correctly indicates that the count cache is disabled, but
#     incorrectly says the software count cache flush is enabled.
#     
#     The root of the problem is that we are trying to handle all
#     combinations of options. But we know now that we only expect to see
#     the software count cache flush enabled if the other options are false.
#     
#     So split the two cases, which simplifies the logic and fixes the bug.
#     We were also missing a space before "(hardware accelerated)".
#     
#     The result is we see one of:
#     
#       Mitigation: Indirect branch serialisation (kernel only)
#       Mitigation: Indirect branch cache disabled
#       Mitigation: Software count cache flush
#       Mitigation: Software count cache flush (hardware accelerated)
#     
#     Fixes: ee13cb249fab ("powerpc/64s: Add support for software count cache flush")
