GUI idle interrupts should be enabled only after we
have enabled coarse grain clock gating (CGCG). This
prevents GFX engine generating idle interrupt even
though CGCG is not completely enabled.
Most of the time this goes un-noticed, but on some
Stoney ASICs this results in GFX engine hang after
system resumes from suspend. The issue is not
particular to Stoney though and could have occured
on any ASIC. The patch fixes this issue.

I noticed some wakeirq flakeyness with consumer drivers not using
autosuspend. For drivers not using autosuspend, the wakeirq may never
get unmasked in rpm_suspend() because of irq desc->depth.
We are configuring dedicated wakeirqs to start with IRQ_NOAUTOEN as we
naturally don't want them running until rpm_suspend() is called.
However, when a consumer driver initially calls pm_runtime_get(), we
now wrongly start with disable_irq_nosync() call on the dedicated
wakeirq that is disabled to start with.
This causes desc->depth to toggle between 1 and 2 instead of the usual
0 and 1. This can prevent enable_irq() from unmasking the wakeirq as
that only happens at desc->depth 1.
This does not necessarily show up with drivers using autosuspend as
there is time for disable_irq_nosync() before rpm_suspend() gets called
after the autosuspend timeout.
Let's fix the issue by adding wirq->status that lazily gets set on
the first rpm_suspend(). We also need PM runtime core private functions
for dev_pm_enable_wake_irq_check() and dev_pm_disable_wake_irq_check()
so we can enable the dedicated wakeirq on the first rpm_suspend().
While at it, let's also fix the comments for dev_pm_enable_wake_irq()
and dev_pm_disable_wake_irq(). Those can still be used by the consumer
drivers as needed because the IRQ core manages the interrupt usecount
for us.

Passing zero for the size to vfio_find_dma() isn't compatible with
matching the start address of an existing vfio_dma. Doing so triggers a
corner case. In vfio_find_dma(), when the start address is equal to
dma->iova and size is 0, check for the end of search range makes it to
take wrong side of RB-tree. That fails the search even though the address
is present in mapped dma ranges.
In functions pin_pages and unpin_pages, the iova which is being searched
is base address of page to be pinned or unpinned. So here size should be
set to PAGE_SIZE, as argument to vfio_find_dma().

vfio_find_dma() is also used to verify last address in unmap range with
size = 0, but in that case address to be searched is calculated with
start + size - 1 and so it works correctly.

Pull networking fixes from David Miller:
1) When dcbnl_cee_fill() fails to be able to push a new netlink
attribute, it return 0 instead of an error code. From Pan Bian.
2) Two suffix handling fixes to FIB trie code, from Alexander Duyck.
3) bnxt_hwrm_stat_ctx_alloc() goes through all the trouble of setting
and maintaining a return code 'rc' but fails to actually return it.
Also from Pan Bian.
4) ping socket ICMP handler needs to validate ICMP header length, from
Kees Cook.
5) caif_sktinit_module() has this interesting logic:
int err = sock_register(...);
if (!err)
return err;
return 0;
Just return sock_register()'s return value directly which is the
only possible correct thing to do.
6) Two bnx2x driver fixes from Yuval Mintz, return a reasonable
estimate from get_ringparam() ethtool op when interface is down and
avoid trying to use UDP port based tunneling on 577xx chips.
7) Fix ep93xx_eth crash on module unload from Florian Fainelli.
8) Missing uapi exports, from Stephen Hemminger.
9) Don't schedule work from sk_destruct(), because the socket will be
freed upon return from that function. From Herbert Xu.
10) Buggy drivers, of which we know there is at least one, can send a
huge packet into the TCP stack but forget to set the gso_size in the
SKB, which causes all kinds of problems.
Correct this when it happens, and emit a one-time warning with the
device name included so that it can be diagnosed more easily.
From Marcelo Ricardo Leitner.
11) virtio-net does DMA off the stack causes hiccups with VMAP_STACK,
fix from Andy Lutomirski.
12) Fix fec driver compilation with CONFIG_M5272, from Nikita
Yushchenko.
13) mlx5 fixes from Kamal Heib, Saeed Mahameed, and Mohamad Haj Yahia.

When using the negative logic (i.e. FLUSH state), after the RQ/SQ reopen
we will have a time interval that the RQ/SQ is not really ready and the
state indicates that its not in FLUSH state because the initial SQ/RQ struct
memory starts as zeros.
Now we changed the state to indicate if the SQ/RQ is opened and we will
set the READY state after finishing preparing all the SQ/RQ resources.

This patch introduces the RX checksum function to check the
status of the hardware calculated checksum and its error and
appropriately convey status to the upper stack in skb->ip_summed
field.
In hardware, we only support checksum for the following
protocols:
1) IPv4,
2) TCP(over IPv4 or IPv6),
3) UDP(over IPv4 or IPv6),
4) SCTP(over IPv4 or IPv6)
but we support many L3(IPv4, IPv6, MPLS, PPPoE etc) and
L4(TCP, UDP, GRE, SCTP, IGMP, ICMP etc.) protocols.
Hardware limitation:
Our present hardware RX Descriptor lacks L3/L4 checksum
"Status & Error" bit (which usually can be used to indicate whether
checksum was calculated by the hardware and if there was any error
encountered during checksum calculation).
Software workaround:
We do get info within the RX descriptor about the kind of
L3/L4 protocol coming in the packet and the error status. These
errors might not just be checksum errors but could be related to
version, length of IPv4, UDP, TCP etc.
Because there is no-way of knowing if it is a L3/L4 error due
to bad checksum or any other L3/L4 error, we will not (cannot)
convey hardware checksum status(CHECKSUM_UNNECESSARY) for such
cases to upper stack and will not maintain the RX L3/L4 checksum
counters as well.
