The EMAC has the option of sending only a single pause frame when
flow control is enabled and the RX queue is full. Although sending
only one pause frame has little value, this would allow admins to
enable automatic flow control without having to worry about the EMAC
flooding nearby switches with pause frames if the kernel hangs.
The option is enabled by using the single-pause-mode private flag.

If MTU is changed the host would reject the send buffer change.
This problem is result of recent change to allow changing send
buffer size.
Every time we change the MTU, we store the previous net_device section
count before destroying the buffer, but we don’t store the previous
section size. When we reinitialize the buffer, its size is calculated
by multiplying the previous count and previous size. Since we
continuously increase the MTU, the host returns us a decreasing count
value while the section size is reinitialized to 1728 bytes every
time.
This eventually leads to a condition where the calculated buf_size is
so small that the host rejects it.

In isdn_ppp_write(), the header (i.e., protobuf) of the buffer is
fetched twice from userspace. The first fetch is used to peek at the
protocol of the message and reset the huptimer if necessary; while the
second fetch copies in the whole buffer. However, given that buf resides
in userspace memory, a user process can race to change its memory content
across fetches. By doing so, we can either avoid resetting the huptimer
for any type of packets (by first setting proto to PPP_LCP and later
change to the actual type) or force resetting the huptimer for LCP
packets.
This patch changes this double-fetch behavior into two single fetches
decided by condition (lp->isdn_device < 0 || lp->isdn_channel <0).

This patch is pretty much a carbon copy of
commit 3079c65214 ("caif: Fix napi poll list corruption")
with "caif" replaced by "emac".
The commit d75b1ade56 ("net: less interrupt masking in NAPI")
breaks emac.
It is now required that if the entire budget is consumed when poll
returns, the napi poll_list must remain empty. However, like some
other drivers emac tries to do a last-ditch check and if there is
more work it will call napi_reschedule and then immediately process
some of this new work. Should the entire budget be consumed while
processing such new work then we will violate the new caller
contract.
This patch fixes this by not touching any work when we reschedule
in emac.

Due to commit db3e50f323 (device property: Get rid of struct
fwnode_handle type field), ACPI_HANDLE() inadvertently became
a GPL-only call. The call path that led to that was:
ACPI_HANDLE()
ACPI_COMPANION()
to_acpi_device_node()
is_acpi_device_node()
acpi_device_fwnode_ops
DECLARE_ACPI_FWNODE_OPS(acpi_device_fwnode_ops);
...and the new DECLARE_ACPI_FWNODE_OPS() includes
EXPORT_SYMBOL_GPL, whereas previously it was a static struct.
In order to avoid changing any of that, let's instead provide ever
so slightly better encapsulation of those struct fwnode_operations
instances. Those do not really need to be directly used in
inline function calls in header files. Simply moving two small
functions (is_acpi_device_node and is_acpi_data_node) out of
acpi_bus.h, and into a .c file, does that.
That leaves the internals of struct fwnode_operations as GPL-only
(which I think was the intent all along), but un-breaks any driver
code out there that relies on the ACPI subsystem's being (historically)
an EXPORT_SYMBOL-usable system. By that, I mean, ACPI_HANDLE() and
other basic ACPI calls were non-GPL-protected.
Also, while I'm there, remove a tiny bit of redundancy that was missed
in the earlier commit, by having is_acpi_node() use the other two
routines, instead of checking fwnode directly.

QCOM_IOMMU selects IOMMU_IO_PGTABLE_LPAE, which bypasses its dependency
on HAS_DMA. Make QCOM_IOMMU depend on HAS_DMA to fix this.

I ran into a build error on x86:
drivers/gpu/drm/exynos/exynos5433_drm_decon.c: In function 'decon_conf_irq':
drivers/gpu/drm/exynos/exynos5433_drm_decon.c:706:2: error: implicit declaration of function 'irq_set_status_flags'; did you mean 'dquot_state_flag'? [-Werror=implicit-function-declaration]
irq_set_status_flags(irq, IRQ_NOAUTOEN);
Adding the missing include fixes the error.

Commit 7d902c05b4 ("drm: Nuke drm_atomic_helper_connector_dpms")
removed drm_atomic_helper_connector_dpms() helper saying that it was a dead
code. It was however indirectly used by Exynos DRM driver for implementing
suspend/resume support. To fix this regression (after that patch Exynos DRM
suspend/resume functions became no-ops and hardware fails to suspend),
this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.

Commit 48a9291672 ("drm/exynos: use drm_for_each_connector_iter()")
replaced unsafe drm_for_each_connector() with drm_for_each_connector_iter()
and removed surrounding drm_modeset_lock calls. However, that lock was
there not only to protect unsafe drm_for_each_connector(), but it was also
required to be held by the dpms code which was called from the loop body.
This patch restores those drm_modeset_lock calls to fix broken suspend
and resume of Exynos DRM subsystem in v4.13 kernel.

Building with gcc-4.6 results in this warning due to
dmar_table_print_dmar_entry being inlined as in newer compiler versions:
WARNING: vmlinux.o(.text+0x5c8bee): Section mismatch in reference from the function dmar_walk_remapping_entries() to the function .init.text:dmar_table_print_dmar_entry()
The function dmar_walk_remapping_entries() references
the function __init dmar_table_print_dmar_entry().
This is often because dmar_walk_remapping_entries lacks a __init
annotation or the annotation of dmar_table_print_dmar_entry is wrong.
This removes the __init annotation to avoid the warning. On compilers
that don't show the warning today, this should have no impact since the
function gets inlined anyway.
