PCI / ACPI / PM: Clear pme_poll for devices in D3cold on wakeup
Commit 448bd85 (PCI/PM: add PCIe runtime D3cold support) added a
piece of code to pci_acpi_wake_dev() causing that function to behave
in a special way for devices in D3cold (so that their configuration
registers are not accessed before those devices are resumed).
However, it didn't take the clearing of the pme_poll flag into
account. That has to be done for all devices, even if they are in
D3cold, or pci_pme_list_scan() will not know that wakeup has been
signaled for the device and will poll its PME Status bit
unnecessarily.
Fix the problem by moving the clearing of the pme_poll flag in
pci_acpi_wake_dev() before the code introduced by commit 448bd85.

sequence: acquire nt->mutex then rtnl, but in the netconsole netdev
notifier we have rtnl then nt->mutex effectively leading to a deadlock.
The NULL pointer dereference that the above commit tries to fix is
actually due to another bug in netpoll_cleanup(). This is fixed by dropping
the mutex from the netdev notifier as it's already protected by rtnl.

The patch

+ if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+ dev_kfree_skb(nskb);
+ goto resubmit;
+ }

pci_unmap_single(skge->hw->pdev,

xen-netback: Don't destroy the netdev until the vif is shut down
Without this patch, if a frontend cycles through states Closing
and Closed (which Windows frontends need to do) then the netdev
will be destroyed and requires re-invocation of hotplug scripts
to restore state before the frontend can move to Connected. Thus
when udev is not in use the backend gets stuck in InitWait.
With this patch, the netdev is left alone whilst the backend is
still online and is only de-registered and freed just prior to
destroying the vif (which is also nicely symmetrical with the
netdev allocation and registration being done during probe) so
no re-invocation of hotplug scripts is required.

drm/fb-helper: don't sleep for screen unblank when an oops is in progress
Otherwise the system will burn even brighter and worse, leave the user
wondering what's going on exactly.
Since we already have a panic handler which will (try) to restore the
entire fbdev console mode, we can just bail out. Inspired by a patch from
Konstantin Khlebnikov. The callchain leading to this, cut&pasted from
Konstantin's original patch:
callstack:
panic()
bust_spinlocks(1)
unblank_screen()
vc->vc_sw->con_blank()
fbcon_blank()
fb_blank()
info->fbops->fb_blank()
drm_fb_helper_blank()
drm_fb_helper_dpms()
drm_modeset_lock_all()
mutex_lock(&dev->mode_config.mutex)
Note that the entire locking in the fb helper around panic/sysrq and kdbg
is ... non-existant. So we have a decent change of blowing up
everything. But since reworking this ties in with funny concepts like the
fbdev notifier chain or the impressive things which happen around
console_lock while oopsing, I'll leave that as an exercise for braver
souls than me.

drm/ttm: fix the tt_populated check in ttm_tt_destroy()
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(),
ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up
inside the driver's unpopulate() hook when populate() has never yet
been called.
On nouveau, the first issue to be hit because of this is that
dma_address[] may be a NULL pointer. After working around this,
ttm_pool_unpopulate() may potentially hit the same issue with
the pages[] array.
It seems to make more sense to avoid calling unpopulate on already
unpopulated TTMs than to add checks to all the implementations.

commit

cnic: Use CHIP_NUM macros from bnx2x.h
changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not. There is another place in cnic that is still using
the old method to determine if FCoE is supported or not. The 2 methods
may not yield the same result after the network interface is brought down
and up. This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.
The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.

RPCSEC_GSS: fix crash on destroying gss auth
This fixes a regression since
eb6dc19d8e72ce3a957af5511d20c0db0a8bd007
"RPCSEC_GSS: Share all credential caches on a per-transport basis" which
could cause an occasional oops in the nfsd code (see below).
The problem was that an auth was left referencing a client that had been
freed. To avoid this we need to ensure that auths are shared only
between descendants of a common client; the fact that a clone of an
rpc_client takes a reference on its parent then ensures that the parent
client will last as long as the auth.
Also add a comment explaining what I think was the intention of this
code.

The legacy muxing was setting pulls for GPIO 48 and 49, so let's
keep that behaviour for now to avoid further regressions for
BT and FM. Also input logic was enabled for MMC CLK line, but
I've verified that the input logic we don't need enabled for
CLK line as it's not bidirectional.
Also, we want to use non-removable instead of ti,non-removable
as the ti,non-removable also sets no_regulator_off_init which
is really not what we want as then wl12xx won't get powered
up and down which is needed for resetting it.
Note that looks like the WLAN interface fails to come up after
a warm reset, but that most likely was also happening with
the legacy booting and needs a separate fix.

if tty && on_exit. This breaks LSB test-suite, in particular test8 in

Put the "!on_exit" check back to restore the old behaviour.
Review by Peter Hurley:
"Yes, this regression was introduced by me in that commit. The effect
of the regression is that ptys will receive a SIGCONT when, in similar
circumstances, ttys would not.
The fact that two test vectors accidentally tripped over this

Current code looks like this:
WARN_ON(lock_policy_rwsem_write(cpu));
update_policy_cpu(policy, new_cpu);
unlock_policy_rwsem_write(cpu);
{lock|unlock}_policy_rwsem_write(cpu) takes/releases policy->cpu's rwsem.
Because cpu is changing with the call to update_policy_cpu(), the
unlock_policy_rwsem_write() will release the incorrect lock.
The right solution would be to release the same lock as was taken earlier. Also
update_policy_cpu() was also called from cpufreq_add_dev() without any locks and
so its better if we move this locking to inside update_policy_cpu().

been soaking in linux-usb for a while now.
We have the usual sparse and build warnings, a Kconfig fix
to a mismerge on dwc3 Kconfig, fix for a possible memory leak
in dwc3, s3c-hsotg won't disconnect when bus goes idle, locking
fix in mv_u3d_core, endpoint disable fix in f_mass_storage.
We also have one device ID added to dwc3's PCI glue layer in order
to support Intel's BayTrail devices.

vhost/scsi: use vmalloc for order-10 allocation
As vhost scsi device struct is large, if the device is
created on a busy system, kzalloc() might fail, so this patch does a
fallback to vzalloc().
As vmalloc() adds overhead on data-path, add __GFP_REPEAT
to kzalloc() flags to do this fallback only when really needed.

batman-adv: set the TAG flag for the vid passed to BLA
When receiving or sending a packet a packet on a VLAN, the
vid has to be marked with the TAG flag in order to make any
component in batman-adv understand that the packet is coming
from a really tagged network.
This fix the Bridge Loop Avoidance behaviour which was not
able to send announces over VLAN interfaces.
