The arm64 config selects MULTI_IRQ_HANDLER, which was renamed to
GENERIC_IRQ_MULTI_HANDLER by commit 4c301f9b6a94 ("ARM: Convert
to GENERIC_IRQ_MULTI_HANDLER"). The 'new' option is already
selected, so just remove the obsolete entry.

We rely on the mmu_notifier call backs to handle the split/merge
of huge pages and thus we are guaranteed that, while creating a
block mapping, either the entire block is unmapped at stage2 or it
is missing permission.
However, we miss a case where the block mapping is split for dirty
logging case and then could later be made block mapping, if we cancel the
dirty logging. This not only creates inconsistent TLB entries for
the pages in the the block, but also leakes the table pages for
PMD level.
Handle this corner case for the huge mappings at stage2 by
unmapping the non-huge mapping for the block. This could potentially
release the upper level table. So we need to restart the table walk
once we unmap the range.

====================
100GbE Intel Wired LAN Driver Updates 2019-03-19
This series contains updates to ice driver only.
Michal adds support for the pruning enable flag to avoid seeing
broadcast packets on different VLANs.
Akeem fixes an issue with VF queues being disabled and the VF netdev
network carrier being lost after reset. Fixed an issue issue when doing
PFR and CORER resets, where all VF VSIs need to be reset and rebuilt
with the main VSIs before replaying all VSIs. Resolved an issue to
properly initialize VFs in the guest OS via PCI passthrough.
Bruce adds a local variable to avoid unnecessary de-references
throughout ice_probe().
Brett cleans up the code a bit by removing the need for a local variable
and re-designs the loop to simply return when get a successful result.
Cleans up the code to replace loop calls with a predefined macro to make
the code more consistent. Updated the driver to ensure ITR granularity
is always 2 usecs. Refactors the calculation of VSIs per PF into a
general function that can calculate per PF allocations for not just VSIs
but across multiple resource types. Improve the driver performance of
the driver when using the default settings by determining the ring size
and the number of descriptors for transmit and receive based on a
calculation with the PAGE_SIZE, ICE_MAX_NUM_DESC, and
ICE_REQ_DESC_MULTIPLE.
Chinh fixes an issue, where a reserved bit was possibly being set when
it should never be set.

Kai-Heng Feng fixes the WoL setting for system suspend, which should
not set to runtime suspend settings for igb. Then fixes a power
management issue with e1000e for CNP+ devices.
Colin Ian King fixes whitespace issue (indentation), which helps with
readability.
Sasha provides the remaining changes for igc, including the enabling of
multi-queues to receive. Added support for displaying and configuring
network flow classification (NFC) via ethtool. Added additional
statistics and basic counters for igc. Fixed a typo, so it aligns with
our other drivers.

Because map updates are distributed lazily, an OSD may not know about
the new blacklist for quite some time after "osd blacklist add" command
is completed. This makes it possible for a blacklisted but still alive
client to overwrite a post-blacklist update, resulting in data
corruption.
Waiting for latest osdmap in ceph_monc_blacklist_add() and thus using
the post-blacklist epoch for all post-blacklist requests ensures that
all such requests "wait" for the blacklist to come into force on their
respective OSDs.

sh_rtc_read_alarm_value() returns 0xff when querying a hardware alarm

alarm values, and fills in missing fields when needed.
While 0xff is handled fine for the year, month, and day fields, and
corrected as considered being out-of-range, this is not the case for the

If we encounter a failure during suspend where this RTC was programmed
to wakeup the system from suspend, but that wakeup couldn't be
configured because the system didn't support wakeup interrupts, we'll
run into the following warning:
Unbalanced IRQ 166 wake disable
WARNING: CPU: 7 PID: 3071 at kernel/irq/manage.c:669 irq_set_irq_wake+0x108/0x278
This happens because the suspend process isn't aborted when the RTC
fails to configure the wakeup IRQ. Instead, we continue suspending the
system and then another suspend callback fails the suspend process and
"unwinds" the previously suspended drivers by calling their resume
callbacks. When we get back to resuming this RTC driver, we'll call
disable_irq_wake() on an IRQ that hasn't been configured for wake.
Let's just fail suspend/resume here if we can't configure the system to
wake and the user has chosen to wakeup with this device. This fixes this
warning and makes the code more robust in case there are systems out
there that can't wakeup from suspend on this line but the user has
chosen to do so.

The OUT endpoint normally blocks (NAK) subsequent packets when a
short packet was received and returns an incomplete queue entry to
the gadget driver. Thereby the gadget driver can detect a short packet
when reading queue entries with a length that is not equal to a
multiple of packet size.
The start_queue() function enables receiving OUT packets regardless of
the content of the OUT FIFO. This results in a race: With the current
code, it's possible that the "!ep->is_in && (readl(&ep->regs->ep_stat)
& BIT(NAK_OUT_PACKETS))" test in start_dma() will fail, then a short
packet will be received, and then start_queue() will call
stop_out_naking(). That's what we don't want (OUT naking gets turned
off while there is data in the FIFO) because then the next driver
request might receive a mixture of old and new packets.
With the patch, this race can't occur because the FIFO's state is
tested after we know that OUT naking is already turned on, and OUT
naking is stopped only when both of the conditions are met. This
ensures that all received data is delivered to the gadget driver,
which can detect a short packet now before new packets are appended
to the last short packet.

Currently we set the default number of Tx and Rx descriptors to 128 by
default. For Rx this amounts to a full page (assuming 4K pages) because
each Rx descriptor is 32 Bytes, but for Tx it only amounts to a half
page because each Tx descriptor is 16 Bytes (assuming 4K pages).
Instead of assuming 4K pages, determine the ring size and the number of
descriptors for Tx and Rx based on a calculation using the PAGE_SIZE,
ICE_MAX_NUM_DESC, and ICE_REQ_DESC_MULTIPLE. This change is being made
to improve the performance of the driver when using the default

This patch adds support for 6PE (RFC 4798) which uses IPv4-mapped IPv6
nexthop to connect IPv6 islands over IPv4 only MPLS network core.
Prior to this fix, to find the link-layer destination mac address, 6PE
enabled host/router was sending IPv6 ND requests for IPv4-mapped IPv6
nexthop address over the interface facing the IPv4 only core which
wouldn't success as the core is IPv6 free.
This fix changes that behavior on 6PE host to treat the nexthop as IPv4
address and send ARP requests whenever the next-hop address is an
IPv4-mapped IPv6 address.
Below topology illustrates the issue and how the patch addresses it.
abcd::1.1.1.1 (lo) abcd::2.2.2.2 (lo)
R0 (PE/host)------------------------R1--------------------------------R2 (PE/host)
<--- IPv4 MPLS core ---> <------ IPv4 MPLS core -------->
eth1 eth2 eth3 eth4
172.18.0.10 172.18.0.11 172.19.0.11 172.19.0.12
ffff::172.18.0.10 ffff::172.19.0.12
<------------------IPv6 MPLS tunnel ---------------------->
R0 and R2 act as 6PE routers of IPv6 islands. R1 is IPv4 only with MPLS tunnels
between R0,R1 and R1,R2.
docker exec r0 ip -f inet6 route add abcd::2.2.2.2/128 nexthop encap mpls 100 via ::ffff:172.18.0.11 dev eth1
docker exec r2 ip -f inet6 route add abcd::1.1.1.1/128 nexthop encap mpls 200 via ::ffff:172.19.0.11 dev eth4
docker exec r1 ip -f mpls route add 100 via inet 172.19.0.12 dev eth3
docker exec r1 ip -f mpls route add 200 via inet 172.18.0.10 dev eth2
With the change, when R0 sends an IPv6 packet over MPLS tunnel to abcd::2.2.2.2,
using ::ffff:172.18.0.11 as the nexthop, it does neighbor discovery for
172.18.18.0.11.

clang points out a harmless signed integer overflow:
drivers/net/ethernet/3com/3c515.c:1530:66: error: implicit conversion from 'int' to 'short' changes value from 32783 to -32753 [-Werror,-Wconstant-conversion]

new_mode = SetRxFilter | RxStation | RxBroadcast;
~ ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
Make the variable unsigned to avoid the overflow.

====================
enc28j60: messaging clean up and ACPI improvements
Most of the patches in the series dedicated to update messaging to use modern
APIs, such as netdev, with a benefit to distinguish devices, if more than one
installed on the system.
Besides that, patch 1 targeting ACPI enabled systems when MAC address provided
there via properties.
And few clean ups are included, such as:
- switching to module_spi_driver()
- converting to use ether_addr_copy() API
- converting to use SPDX
Since v2:
- cover letter is added

There is no need to include linux/init.h when at the same time
we include linux/module.h.
Remove redundant inclusion.

The debug prints of network operations will look better if network
device name is printed. The benefit of that is a possibility to distinguish
the actual hardware when more than one is installed on the system.
Convert appropriate printk(KERN_DEBUG) to netdev_print(KERN_DEBUG, ndev).

The debug prints of hardware status and operations will look better
if SPI device name is printed. The benefit of that is a possibility
to distinguish the actual hardware when more than one is installed
on the system.

Instead of using open coded printk(KERN_<LEVEL>) switch the driver to use
dev_<level> macros.
Note, the device name will be printed in full, which is beneficial when
more than one card installed on the system.
