This bug was introduced by commit
7a163bfb7ce50895bbe67300ea610d31b9c09230 ("netconsole: avoid a crash with
multiple sysfs writers"). In store_enabled() we have the following
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.

skge: fix broken driver
The patch
136d8f377e1575463b47840bc5f1b22d94bf8f63 broke the skge driver.
Note this part of 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,

The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the

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.

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

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

cnic: Fix crash in cnic_bnx2x_service_kcq()
commit
104a43edb264321a4d41850e98153b4fa8a9ef42
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.

changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i

so that the existing userspace driver will calculate the correct doorbell
address and continue to work.

Most users of get_cycles() invoke it as a timing interface. That's why
in modern kernels it was never very much missed for. /dev/random however
uses get_cycles() in the how the jitter in the interrupt timing contains
some useful entropy.

tty: disassociate_ctty() sends the extra SIGCONT
Starting from v3.10 (probably commit
f91e2590410b: "tty: Signal
foreground group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit. This breaks LSB test-suite, in particular test8 in
_exit.c and test40 in sigcon5.c.
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
regression suggests that some other apps may as well.
Thanks for catching this"
