the flag is optional if the subdevice only supports data transfer in one
direction.

If the subdevice only supports asynchronous data transfer in a sing
direction, set the `CMDF_WRITE` flag to the correct state so that Comedi
can make use of it later.  In the case of the `COMEDI_CMDTEST` ioctl,

the `CMDF_BOGUS` command flag is set.  Since `__comedi_get_user_cmd()`

Staging: lustre: lnet: Improve 'incarnation' stamp

ksock_net_t uses a __u64 quantity as an 'incarnation' timestamp. This is also
passed on in hello messages and used to detect if a reboot has occurred.
This 'incarnation' is obtained using do_gettimeofday.It is only used in equality
checks, so the absolute value does not matter.

This patch replaces do_gettimeofday with ktime_get_ns for the following reasons:
1. ktime_get_ns returns a __u64 which is safer than 'struct timeval'
which will overflow on 32-bit systems in year 2038 and beyond.
2. Reduced compute: ktime_get_ns is faster than the multiply/add
   combination used in this function

In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.

Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.

This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support.  Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.

KVM: x86: Fix far-jump to non-canonical check

Commit d1442d85cc30 ("KVM: x86: Handle errors when RIP is set during far
jumps") introduced a bug that caused the fix to be incomplete.  Due to
incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit
segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may
not trigger #GP.  As we know, this imposes a security problem.

In addition, the condition for two warnings was incorrect.
