2c20443ec2 Merge tag 'acpi-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
 "These revert two ACPICA commits that are not needed any more, rework
  the property graphs support in ACPI to be more aligned with the
  analogous DT code, add some new quirks and remove one that isn't
  needed any more, add a special platform driver to enumerate multiple
  I2C devices hooked up to the same device object in the ACPI tables and
  update the battery and button drivers.

  Specifics:

   - Revert two ACPICA commits that are not needed any more (Erik
     Schmauss).

   - Rework property graph support in the ACPI device properties
     framework to make it behave more like the analogous DT code and
     update the documentation of it (Sakari Ailus).

   - Change the default ACPI device status after initialization to
     ACPI_STA_DEFAULT instead of 0 (Hans de Goede).

   - Add a special platform driver for enumerating multiple I2C devices
     hooked up to the same object in the ACPI tables (Hans de Goede).

   - Fix the ACPI battery driver to avoid reporting full capacity on
     systems without support for that and clean it up (Hans de Goede,
     Dmitry Rozhkov, Lucas Rangit Magasweran).

   - Add two system wakeup quirks to the ACPI EC driver (Aaron Ma, Mika
     Westerberg).

   - Add the touchscreen on Dell Venue Pro 7139 to the list of "always
     present" devices to make it work (Tristian Celestin).

   - Revert a special tables handling quirk for Dell XPS 9570 and
     Precision M5530 which is not needed any more (Kai Heng Feng).

   - Add support for a new OEM _OSI string to allow system vendors to
     work around issues with NVidia HDMI audio (Alex Hung).

   - Prevent the ACPI button driver from reporting excessive system
     wakeup events and clean it up (Ravi Chandra Sadineni, Randy
     Dunlap).

   - Clean up two minor code style issues in the ACPI core and GHES
     handling on ARM64 (Dongjiu Geng, John Garry, Tom Todd)"

60081dcc4f net: hns3: Fix for phy link issue when using marvell phy driver
For marvell phy m88e1510, bit SUPPORTED_FIBRE of phydev->supported
is default on. Both phy_resume() and phy_suspend() will check the
SUPPORTED_FIBRE bit and write register of fibre page.

Currently in hns3 driver, the SUPPORTED_FIBRE bit will be cleared
after phy_connect_direct() finished. Because phy_resume() is called
in phy_connect_direct(), and phy_suspend() is called when disconnect
phy device, so the operation for fibre page register is not symmetrical.
It will cause phy link issue when reload hns3 driver.

This patch fixes it by disable the SUPPORTED_FIBRE before connecting
phy.

1bbf3aed25 bnxt_en: take coredump_record structure off stack
The bnxt_coredump_record structure is very long, causing a warning
about possible stack overflow on 32-bit architectures:

drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c: In function 'bnxt_get_coredump':
drivers/net/ethernet/broadcom/bnxt/bnxt_ethtool.c:2989:1: error: the frame size of 1188 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

I could not see any reason to operate on an on-stack copy of the

also simplifies the code here.

3d46eee5a5 bnxt_en: avoid string overflow for record->system_name
The utsname()->nodename string may be 64 bytes long, and it gets
copied without the trailing nul byte into the shorter record->system_name,
as gcc now warns:

Using strlcpy() at least avoids overflowing the destination buffer
and adds proper nul-termination. It may still truncate long names
though, which probably can't be solved here.

7c53a72245 r8169: don't use MSI-X on RTL8168g
There have been two reports that network doesn't come back on resume
from suspend when using MSI-X. Both cases affect the same chip version
(RTL8168g - version 40), on different systems. Falling back to MSI
fixes the issue.
Even though we don't really have a proof yet that the network chip
version is to blame, let's disable MSI-X for this version.

63ae7949e9 net: socionext: Use descriptor info instead of MMIO reads on Rx
MMIO reads for remaining packets in queue occur (at least)twice per
invocation of netsec_process_rx(). We can use the packet descriptor to
identify if it's owned by the hardware and break out, avoiding the more
expensive MMIO read operations. This has a ~2% increase on the pps of the
Rx path when tested with 64byte packets

In cases if some of the entries were not found in forwarding table
while killing vlan, the rest not needed entries still left in the
table. No need to stop, as entry was deleted anyway. So fix this by
returning error only after all was cleaned. To implement this, return
-ENOENT in cpsw_ale_del_mcast() as it's supposed to be.

0f5c6c30a0 net: mvneta: fix mvneta_config_rss on armada 3700
The mvneta Ethernet driver is used on a few different Marvell SoCs.
Some SoCs have per cpu interrupts for Ethernet events, the driver uses
a per CPU napi structure for this case. Some SoCs such as armada 3700
have a single interrupt for Ethernet events, the driver uses a global
napi structure for this case.

Current mvneta_config_rss() always operates the per cpu napi structure.
Fix it by operating a global napi for "single interrupt" case, and per
cpu napi structure for remaining cases.
