Sean Christopherson ad120bc869 KVM: KVM: Use cpumask_available() to check for NULL cpumask when kicking vCPUs ... [ Upstream commit 0bbc2ca851 ] Check for a NULL cpumask_var_t when kicking multiple vCPUs via cpumask_available(), which performs a !NULL check if and only if cpumasks are configured to be allocated off-stack. This is a meaningless optimization, e.g. avoids a TEST+Jcc and TEST+CMOV on x86, but more importantly helps document that the NULL check is necessary even though all callers pass in a local variable. No functional change intended.
