Module Name: src
Committed By: jruoho
Date: Thu Mar 3 19:24:43 UTC 2011
Modified Files:
src/sys/dev/acpi: acpi_cpu.c
Log Message:
Add DMI quirk support via pmf_get_platform(9). If any of the listed models
are matched, the whole driver will be prevented from attaching. The first
entry is Supermicro PDSMi-LN4+ (a BIOS bug with bogus P-state entries).
