After d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt
masking in NAPI) the napi instance is removed from the per-cpu list
prior to calling the n->poll(), and is only requeued if all of the
budget was used. This inadvertently broke netfront because netfront
does not use NAPI correctly.
If netfront had not used all of its budget it would do a final check
for any Rx responses and avoid calling napi_complete() if there were
more responses. It would still return under budget so it would never
be rescheduled. The final check would also not re-enable the Rx
interrupt.
Additionally, xenvif_poll() would also call napi_complete() /after/
enabling the interrupt. This resulted in a race between the
napi_complete() and the napi_schedule() in the interrupt handler. The
use of local_irq_save/restore() avoided by race iff the handler is
running on the same CPU but not if it was running on a different CPU.
Fix both of these by always calling napi_compete() if the budget was
not all used, and then calling napi_schedule() if the final checks
says there's more work.

Otherwise we get things like:
warning: (NET_DSA_BCM_SF2 && BCMGENET && SYSTEMPORT) selects FIXED_PHY which has unmet direct dependencies (NETDEVICES && PHYLIB=y)
In order to make this work we have to rename fixed.c to fixed_phy.c
because the regulator drivers already have a module named "fixed.o".

tun/macvtap: TUNSETIFF fixes
Dan Carpenter reported the following:
static checker warning:
drivers/net/tun.c:1694 tun_set_iff()
warn: 0x17100 is larger than 16 bits
drivers/net/tun.c
1692
1693 tun->flags = (tun->flags & ~TUN_FEATURES) |
1694 (ifr->ifr_flags & TUN_FEATURES);
1695
It's complaining because the "ifr->ifr_flags" variable is a short
(should it be unsigned?). The new define:
#define IFF_VNET_LE 0x10000
doesn't fit in two bytes. Other suspect looking code could be:
return __virtio16_to_cpu(q->flags & IFF_VNET_LE, val);
And that's true: we have run out of IFF flags in tun.
So let's not try to add more: add simple GET/SET ioctls
instead. Easy to test, leads to clear semantics.
Alternatively we'll have to revert the whole thing for 3.19,
but that seems more work as this has dependencies
in other places.
While here, I noticed that macvtap was actually reading
ifreq flags as a 32 bit field.
Fix that up as well.

ifreq flags field is only 16 bit wide, so setting IFF_VNET_LE there has
no effect:
doesn't fit in two bytes.
The tests passed apparently because they have an even number of bugs,
all cancelling out.
Luckily we didn't release a kernel with this flag, so it's
not too late to fix this.
Add TUNSETVNETLE/TUNGETVNETLE to really achieve the purpose
of IFF_VNET_LE.
This has an added benefit that if we ever want a BE flag,
we won't have to deal with weird configurations like
setting both LE and BE at the same time.
IFF_VNET_LE will be dropped in a follow-up patch.

The default linker behavior is to optimize identical literal values
and remove unnecessary overhead. However, because of a bug in the
linker, this currently results in an error ('call target out of range').

Pull staging driver updates from Greg KH:
"Here's the big staging tree pull request for 3.19-rc1.
We continued to delete more lines than were added, always a good
thing, but not at a huge rate this release, only about 70k lines
removed overall mostly from removing the horrid bcm driver.
Lots of normal staging driver cleanups and fixes all over the place,
well over a thousand of them, the shortlog shows all the horrid
details.
The "contentious" thing here is the movement of the Android binder
code out of staging into the "real" part of the kernel. This is code
that has been stable for a few years now and is working as-is in the
tens of millions of devices with no issues. Yes, the code is horrid,
and the userspace api leaves a lot to be desired, but it's not going
to change due to legacy issues that we have no control over. Because
so many devices and companies rely on this, and the code is stable,
might as well promote it out of staging.
This was all discussed at the Linux Plumbers conference, and everyone
participating agreed that this was the best way forward.
There is work happening to replace the binder code with something new
that is happening right now, but I don't expect to see the results of
that work for another year at the earliest. If that ever happens, and
Android switches over to it, I'll gladly remove this version.
As for maintainers, I'll be glad to maintain this code, I've been
doing it for the past few years with no problems. I'll send a
MAINTAINERS entry for it before 3.19-final is out, still need to talk
to the Google developers about if they are willing to help with it or
not, last I checked they were, which was good.
All of these patches have been in linux-next for a while with no
reported issues"

- AMD KFD driver merge
This is the AMD HSA interface for exposing a lowlevel interface for

- Initial atomic modesetting work
The need for an atomic modesetting interface to allow userspace to
try and send a complete set of modesetting state to the driver has
arisen, and been suffering from neglect this past year. No more,
the start of the common code and changes for msm driver to use it
are in this tree. Ongoing work to get the userspace ioctl finished
and the code clean will probably wait until next kernel.

The VM_FAULT_RETRY handling was confusing and incorrect for the case of
returning to kernel mode. We need to handle the exception table fixup
if we return to kernel mode due to a fatal signal - it will basically
look to the kernel user mode access like the access failed due to the VM
going away from udner it. Which is correct - the process is dying - and
avoids the whole "repeat endless kernel page faults" case.
Handling the VM_FAULT_RETRY early and in just one place also simplifies
the mmap_sem handling, since once we've taken care of VM_FAULT_RETRY we
know that we can just drop the lock. The remaining accounting and
possible error handling is thread-local and does not need the mmap_sem.

Debug code prints the fifo name via custom dev_warn() wrappers. The
fifo_names array is only non-zero when debugging is manually enabled,
which is all well and good. However, it's *not* good that this array
uses zero-length arrays in the non-debug case, and so it doesn't
actually have any memory allocated to it. This means that as far as we
know, fifo_names[i] actually points to garbage memory.
I've seen this in my log:
[ 4601.205511] brcmsmac bcma0:1: wl0: brcms_c_d11hdrs_mac80211: �GeL txop exceeded phylen 137/256 dur 1602/1504

====================
net/macb: fix multiqueue support patch up
This series of patches is a fixup for the multiqueue support patch.
The first patch fixes a bug introduced by the multiqueue support patch.
The second one doesn't fix a bug but simplify the source code by removing
useless calls to devm_free_irq() since we use managed device resources for
IRQs.
They were applied on the net-next tree and tested with a sama5d36ek board.

Inside macb_probe(), when devm_request_irq() fails on queue q, there is no need
to call devm_free_irq() on queues 0..q-1 because the managed device resources
are released later when calling free_netdev().
Also removing devm_free_irq() call from macb_remove() for the same reason.

fix a bug introduced by the multiqueue support patch:
"net/macb: add TX multiqueue support for gem"
the "bp" pointer to the netdev private data was dereferenced and used after the
associated memory had been freed by calling free_netdev().

If CONFIG_OF is not set:
drivers/net/ethernet/stmicro/stmmac/dwmac-sti.c: In function ‘sti_dwmac_parse_data’:
drivers/net/ethernet/stmicro/stmmac/dwmac-sti.c:318: warning: ‘rs’ is used uninitialized in this function
of_property_read_string() will return -ENOSYS in this case, and rs will
be an uninitialized pointer.
While the fallback clock selection is already selected correctly in this
case, the string comparisons should be skipped too, else the system will
crash while dereferencing the uninitialized pointer.

drivers/net/ethernet/smsc/smc91x.c:2222:2: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration]
Fix this by letting the driver depend on GPIOLIB if OF is selected.

The NBMA GRE tunnels temporarily push GRE header that contain the
per-packet NBMA destination on the skb via header ops early in xmit
path. It is the later pulled before the real GRE header is constructed.
The inner mac was thus set differently in nbma case: the GRE header
has been pushed by neighbor layer, and mac header points to beginning
of the temporary gre header (set by dev_queue_xmit).
Now that the offloads expect mac header to point to the gre payload,
fix the xmit patch to:
- pull first the temporary gre header away
- and reset mac header to point to gre payload
This fixes tso to work again with nbma tunnels.
Fixes: 14051f0452a2 ("gre: Use inner mac length when computing tunnel length")
