The following patch...
[PATCH 1/1] x86: replace cpu_up hard-coded mdelay with variable
enables reducing cpu_up() time by 10ms on modern systems.
This means that for every processor in the system, boot-time and resume-time can be reduced by 10ms per-processor.
Once this patch is accepted, I'll send a subsequent patch to update the default delay, as appropriate.
thanks, Len Brown, Intel Open Source Technology Center
