The read_persistent_clock() uses a timespec, which is not year 2038 safe
on 32bit systems. On parisc architecture, we have implemented generic RTC
drivers that can be used to compensate the system suspend time, but the
RTC time can not represent the nanosecond resolution, so this patch just

The read_persistent_clock() uses a timespec, which is not year 2038 safe
on 32bit systems. Moreover on m68k architecture, we have implemented generic
RTC drivers that can be used to compensate the system suspend time. So
we can remove the obsolete read_persistent_clock().

The additional brakets added to tpm_set_next_event's return

When sending control commands, virtio net sets up several buffers for
DMA. The buffers are all part of the net device which means it's
actually allocated by kvmalloc so it's in theory (on extreme memory
pressure) possible to get a vmalloc'ed buffer which on some platforms
means we can't DMA there.
Programming vids (adding or removing them) still passes
guest-endian values in the DMA buffer. That's wrong
if guest is big-endian and when virtio 1 is enabled.
Note: this is on top of a previous patch:
virtio_net: split out ctrl buffer
Fixes: 9465a7a6f ("virtio_net: enable v1.0 support")
Here are a couple of fixes related to the virtio control buffer.
Lightly tested on x86 only.

This implements a misc character device named "qrtr-tun" for the purpose
of allowing user space applications to implement endpoints in the qrtr
network.
This allows more advanced (and dynamic) testing of the qrtr code as well
as opens up the ability of tunneling qrtr over a network or USB link.

The duplication is
The initializing of q->root_blkg is currently outside of queue lock
and rcu, so the blkg may be destroied before the initializing, which
may cause dangling/null references. On the other side, the destroys
of blkg are protected by queue lock or rcu. Put the initializing
inside the queue lock and rcu
The comment before blkg_create() in blkcg_init_queue() was moved
from blkcg_activate_policy() by commit ec13b1d6f0a0457312e615, but
it does not suit for the new context.

What perchance might be the advantage of introducing multiple exits
into proc_setgroups_write?
I strongly suspect that if you look at the generated code it will
be worse after your patch.

Two kernel threads may get the same value for agent.hi_tid, if the

The ast2500 has an additional reset register that contains resets not
present in the ast2400. This enables support for this register, and adds
the one reset line that is controlled by it.

Hi Ingo,

If we want to boot up some hotpluggable node, their memory can't be
shown.
IMO, only few machines can support physical NUMA No
