843e19887f64dde75055cf8842fc4db2171eff45johnlev/ Inline functions for the x64 kernel running on the hypervisor
843e19887f64dde75055cf8842fc4db2171eff45johnlev/* XXPV studio bug r10 is changed to eax by compiler */
843e19887f64dde75055cf8842fc4db2171eff45johnlev * Read the -real- TSC.
843e19887f64dde75055cf8842fc4db2171eff45johnlev * This is difficult to virtualize on the hypervisor given there is
843e19887f64dde75055cf8842fc4db2171eff45johnlev * no way to prevent preemption; thus this inline function
843e19887f64dde75055cf8842fc4db2171eff45johnlev * should only be used in the middle of the paravirtualized
843e19887f64dde75055cf8842fc4db2171eff45johnlev * implementation of tsc_read.
