[PATCH 0/1] speeding up cpu_up()
From: Len Brown
Date: Sat Apr 18 2015 - 20:53:37 EST
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.
