From: Milan Broz <mbroz@redhat.com>
Do not use unsigned int if there is test for negative number...
See drivers/acpi/processor_perflib.c static unsigned int ignore_ppc = -1; ... if (event == CPUFREQ_START && ignore_ppc <= 0) { ignore_ppc = 0; ...
Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> --- cherry-picked from mainline 9f497bcc695fb828da023d74ad3c966b1e58ad21
Let's see if this time it will make it for 2.6.26.6? Without this patch, anything that needs passive cooling will just heat up until it either suffers an emergency thermal shutdown, or burns to cinders.
PLEASE apply to 2.6.26 stable. Thank you very much.
