Subject: [PATCH 0/1] speeding up cpu_up()

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
