cpufreq: acpi-cpufreq: Report if CPU doesn't support boost technologies
There is some rare cases where CPB (and possibly IDA) are missing on processors. This is the case fixed by commit f7f3dc00f612 ("x86/cpu/AMD: Fix erratum 1076 (CPB bit)") and following. In such context, the boost status isn't reported by /sys/devices/system/cpu/cpufreq/boost. This commit is about printing a message to report that the CPU doesn't expose the boost capabilities. This message could help debugging platforms hit by this phenomena. Signed-off-by: Erwan Velu <e.velu@criteo.com> [ rjw: Change the message text somewhat ] Signed-off-by: Rafael J.
