Port diff-arch-x86-introduce-cpuid-override
Recent Intel CPUs rejected CPUID masking, which is required for flex
migration, in favor of CPUID faulting. So we need to support it in
kenrel.
This patch adds user writable file /proc/vz/cpuid_override, which
contains CPUID

Show cpu_i flags as flags of vcpu_i.
Extracted from "Initial patch". Merged several reworks.
TODO: Maybe replace/rework on_each_cpu() with smp_call_function_single().
Then we won't need split c_start() in previous patch (as the call
function will be called right before
We are using cpuid faults to emulate cpuid in containers. This
conflicts with arch_prctl(ARCH_SET_CPUID, 0) which allows to enable
cpuid faulting so that cpuid instruction causes SIGSEGV.
Add TIF_CPUID_OVERRIDE thread info flag which is added on all
!ve0 tasks. And check this flag along with

This function must provide guarantees for readers, that
ve_ns != NULL under rcu_read_lock means the rest of context
(say, ve->init_task) is table.
But now order is wrong, and it does not guarantee that. Fix it.
v2: Use local variable for ve_ns, otherwise net_ns write results
in NULL pointer
