Subject: KVM: ia64: Correct itc_offset calculations
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3032b925f00ba2653f7695d356d6f8284c82038d;p=linux-beck.git

KVM: ia64: Correct itc_offset calculations

Init the itc_offset for all possible vCPUs. The current code by
mistake ends up only initializing the offset on vCPU 0.

Spotted by Gleb Natapov.
