Subject: x86/time: initialise time earlier during start_secondary()
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=dd2658f966bc9e01a0a5fad9c53350d681067013;p=people%2Froyger%2Fxen.git

x86/time: initialise time earlier during start_secondary()

It is safe to do so, and useful for "[second.microseconds]" style timestamps
on printk()s during secondary bringup.
