We want to remove 'struct timeval' and related interfaces since this is
generally not safe for use beyond 2038.
For peak_usb, we can simplify the internal interface by using ktime_t
directly. This should not change any behavior, but it avoids a few
conversions.

This changes the calculation of the timestamps to use ktime_t
instead of struct timeval as the base. This gets rid of one
of the few remaining users of the deprecated ktime_to_timeval()
and timeval_to_ktime() helpers.
The code should also get more efficient, as we have now removed

One minor fix in the error leg of the qla2xxx driver (it oopses the
system if we get an error trying to start the internal kernel thread).
The fix is minor because the problem isn't often encountered in the
field (although it can be induced by inserting the module in a low
memory environment).
These patches are intended for v4.16-rc1 as they depend on the
HDMI codec patch which is going to be merged in coming merge

Here, finally, is a new spin of the task isolation work (v16), with
changes based on the issues that were raised at last year's Linux
Plumbers Conference and in the email discussion that followed.
This version of the patch series cleans up a number of areas that were
a little dodgy in the
In commit f01f17d3705b ("mm, vmstat: make quiet_vmstat lighter")
the quiet_vmstat() function became asynchronous, in the sense that
the vmstat work was still scheduled to run on the core when the
function returned. For task isolation, we need a synchronous
version of the function that guarantees
This function checks to see if a vmstat worker is not running,
and the vmstat diffs don't require an update. The function is

actually do some work to quiet vmstat.

Task isolation wants to be able to verify that a remote core is
running an isolated task to determine if it should generate a
diagnostic, and also possibly interrupt it.
This API returns a pointer to the task_struct of the task that
was running on the specified core at the moment of the request;
We add the necessary call to task_isolation_start() in the
prepare_exit_to_usermode() routine. We already unconditionally
call into this routine if TIF_NOHZ is set, since that's where
we do the user_enter() call.
We add calls to task_isolation_interrupt() in places where exceptions
may not

On machines where the GART aperture is mapped over physical RAM
/proc/vmcore contains the remapped range and reading it may
cause hangs or reboots. This range needs to be excluded from /proc/vmcore.
This has originally been implemented by commit dd5f726076cc ("kexec:
