The vhost_set_vring_num_addr() could be called in the middle of
invalidate_range_start() and invalidate_range_end(). If we don't reset
invalidate_count after the un-registering of MMU notifier, the
invalidate_cont will run out of sync (e.g never reach zero). This will

There's no need for RCU synchronization in vhost_uninit_vq_maps()

We used to use RCU to synchronize MMU notifier with worker. This leads

notifier. This path switch to use a
The return value of mmu_notifier_register() is not checked in
vhost_vring_set_num_addr(). This will cause an out of sync between mm
and MMU notifier thus a double free. To solve this, introduce a
boolean flag to track whether MMU notifier is registered and only do
unregistering when it was true.
We should not setup uaddr for the invalid address, otherwise we may
try to pin or prefetch mapping of wrong pages.

As spin_unlock_irq will enable interrupts.
Function tsi108_stat_carry is called from interrupt handler tsi108_irq.
Interrupts are enabled in interrupt handler.
Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_(un)lock_irq
in IRQ context to avoid this.

Hi all,
Today's linux-next merge of the sound-asoc tree (yesterday' version)
got a conflict in:
sound/soc/intel/skylake/skl.c
between commit:
19abfefd4c76 ("ALSA: hda: Direct MMIO accesses")
from the sound tree and commit:
bcc2a2dc3ba8 ("ASoC: Intel: Skylake: Merge skl_sst and skl into
/hda-bus-ops-cleanup' of
https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-5.4")
Looks like the merge resolution is not quite right.
I have used the sound-asoc tree from next-20190808 for today.

I wrote a coccinelle script to detect possible chances
of utilizing devm_() APIs to simplify the driver.
The script found 147 drivers in total and 22 of them
have be patched.
Within the 125 left ones, at least 31 of them (24.8%)
are hindered from benefiting from devm_() APIs because
of lack of a
Hi all,
After merging the sound tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

Currently, VF driver has two kinds of interrupts, reset & CMDQ RX.
For revision 0x21, according to the UM, each interrupt should be
cleared by write 0 to the corresponding bit, but the implementation
writes 0 to the whole register in fact, it will clear other
interrupt at the same time, then the

No. The point of obscuring kernel addresses is that if the attacker manages to
find a way to get the kernel to spit

Before PF asserting function reset, it should make sure
that all its VFs have been ready, otherwise, it will cause
some hardware errors.

This patch refactors the hns3_fill_desc_vtags function
by avoiding passing too many parameters, reducing indent

This patch also adds the hns3_fill_skb_desc function to

If the input length reaches the maximum value of size_t, the reverse is
triggered when 1 is added. In addition, there is no need to have such a
large length. Therefore, the input length should be checked and the value
should be less than or equal to 1024.
