Pull READ/WRITE_ONCE rework from Will Deacon:
"This the READ_ONCE rework I've been working on for a while, which
bumps the minimum GCC version and improves code-gen on arm64 when
stack protector is enabled"
[ Side note: I'm _really_ tempted to raise the minimum gcc version to
4.9, so that we can just say that we require _Generic() support.
That would allow us to more cleanly handle a lot of the cases where we
depend on very complex macros with 'sizeof' or __builtin_choose_expr()
with __builtin_types_compatible_p() etc.
This branch has a workaround for sparse not handling _Generic(),
either, but that was already fixed in the sparse development branch,
so it's really just gcc-4.9 that we'd require. - Linus ]

vxlan driver should be using helpers to access nexthop struct
internals. Remove open check if whether nexthop is multipath in
favor of the existing nexthop_is_multipath helper. Add a new
helper, nexthop_has_v4, to cover the need to check has_v4 in
a group.

fdb nexthops are marked with a flag. For standalone nexthops, a flag was
added to the nh_info struct. For groups that flag was added to struct
nexthop when it should have been added to the group information. Fix
by removing the flag from the nexthop struct and adding a flag to nh_group
that mirrors nh_info and is really only a caching of the individual types.
Add a helper, nexthop_is_fdb, for use by the vxlan code and fixup the
internal code to use the flag from either nh_info or nh_group.

- propagate fdb_nh in remove_nh_grp_entry

Pull clk updates from Stephen Boyd:
"This time around we have four lines of diff in the core framework,
removing a function that isn't used anymore. Otherwise the main new
thing for the common clk framework is that it is selectable in the
Kconfig language now. Hopefully this will let clk drivers and clk
consumers be testable on more than the architectures that support the
clk framework. The goal is to introduce some Kunit tests for the
framework.
Outside of the core framework we have the usual set of various driver
updates and non-critical fixes. The dirstat shows that the new
Baikal-T1 driver is the largest addition this time around in terms of
lines of code. After that the x86 (Intel), Qualcomm, and Mediatek
drivers introduce many lines to support new or upcoming SoCs. After
that the dirstat shows the usual suspects working on their SoC support
by fixing minor bugs, correcting data and converting some of their DT
bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix
clock support on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and
clk-pllv3 drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support
aarch32 mode on aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using
composite clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102
defined bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx

via the platform level interrupt controller) and other per-HART
local interrupts.
We add a driver for the RISC-V local interrupt controller, which
eventually replaces the RISC-V architecture code, allowing for a
better split between arch code and drivers.
The driver is compliant with RISC-V Hart-Level Interrupt Controller
DT bindings located at:

The plic_find_hart_id() can be useful to other interrupt controller
drivers (such as RISC-V local interrupt driver) so we rename this
function to riscv_of_parent_hartid() and place it in arch directory
along with riscv_of_processor_hartid().

The adapter info MAD is used to send the client info and receive the host
info as a response. A persistent buffer is used and as such the client info
is overwritten after the response. During the course of a normal adapter
reset the client info is refreshed in the buffer in preparation for sending
the adapter info MAD.
However, in the special case of LPM where we reenable the CRQ instead of a
full CRQ teardown and reset we fail to refresh the client info in the
adapter info buffer. As a result, after Live Partition Migration (LPM) we
erroneously report the host's info as our own.

This code was using get_user_pages*(), in a "Case 1" scenario (Direct IO),
using the categorization from [1]. That means that it's time to convert the
get_user_pages*() + put_page() calls to pin_user_pages*() +
unpin_user_pages() calls.
There is some helpful background in [2]: basically, this is a small part of
fixing a long-standing disconnect between pinning pages, and file systems'
use of those pages.
Note that this effectively changes the code's behavior as well: it now
ultimately calls set_page_dirty_lock(), instead of SetPageDirty().This is
probably more accurate.
As Christoph Hellwig put it, "set_page_dirty() is only safe if we are
dealing with a file backed page where we have reference on the inode it
hangs off." [3]
Also, this deletes one of the two FIXME comments (about refcounting),
because there is nothing wrong with the refcounting at this point.

NULL pointer dereference happens when the following conditions are met:
1) A SCSI command is received for a non-existing LU or cdb initialization
fails in target_setup_cmd_from_cdb().
2) Tracing is enabled.
The following call sequences lead to NULL pointer dereference:
1) iscsit_setup_scsi_cmd
transport_lookup_cmd_lun <-- lookup fails.
or
target_setup_cmd_from_cdb() <-- cdb initialization fails
iscsit_process_scsi_cmd
iscsit_sequence_cmd
transport_send_check_condition_and_sense
trace_target_cmd_complete <-- NULL dereference
2) target_submit_cmd_map_sgls
transport_lookup_cmd_lun <-- lookup fails
or
target_setup_cmd_from_cdb() <-- cdb initialization fails
transport_send_check_condition_and_sense
trace_target_cmd_complete <-- NULL dereference
In the above sequence, cmd->t_task_cdb is uninitialized which when
referenced in trace_target_cmd_complete() causes NULL pointer dereference.
The fix is to use the helper, target_cmd_init_cdb() and call it after
transport_init_se_cmd() is called, so that cmd->t_task_cdb can be
initialized and hence can be referenced in trace_target_cmd_complete().

Initialization of orig_fe_lun is moved to transport_init_se_cmd() from
transport_lookup_cmd_lun(). This helps for the cases where the SCSI request
fails before the call to transport_lookup_cmd_lun() so that
trace_target_cmd_complete() can print the LUN information to the trace
buffer. Due to this change, the lun parameter is removed from
transport_lookup_cmd_lun() and transport_lookup_tmr_lun().

The netif_running() test looks at __LINK_STATE_START which
gets set before ndo_open() is called, there is a window of
time between that and when the queues are actually ready to
be run. If ionic_check_link_status() notices that the link is
up very soon after netif_running() becomes true, it might try
to run the queues before they are ready, causing all manner of
potential issues. Since the netdev->flags IFF_UP isn't set
until after ndo_open() returns, we can wait for that before
we allow ionic_check_link_status() to start the queues.
On the way back to close, __LINK_STATE_START is cleared before
calling ndo_stop(), and IFF_UP is cleared after. Both of
these need to be true in order to safely stop the queues
from ionic_check_link_status().

The dynamic key update for addr_list_lock still causes troubles,
for example the following race condition still exists:
CPU 0: CPU 1:
(RCU read lock) (RTNL lock)
dev_mc_seq_show() netdev_update_lockdep_key()
-> lockdep_unregister_key()
-> netif_addr_lock_bh()
because lockdep doesn't provide an API to update it atomically.
Therefore, we have to move it back to static keys and use subclass
for nest locking like before.
In commit 1a33e10e4a95 ("net: partially revert dynamic lockdep key
changes"), I already reverted most parts of commit ab92d68fc22f
("net: core: add generic lockdep keys").
This patch reverts the rest and also part of commit f3b0a18bb6cb
("net: remove unnecessary variables and callback"). After this
patch, addr_list_lock changes back to using static keys and
subclasses to satisfy lockdep. Thanks to dev->lower_level, we do
not have to change back to ->ndo_get_lock_subclass().
And hopefully this reduces some syzbot lockdep noises too.

Making module name conflicts a fatal error breaks sparc64 allmodconfig:
Error log:
error: the following would cause module name conflict:
drivers/char/adi.ko
drivers/input/joystick/adi.ko
Renaming one of the modules would solve the problem, but then cause other
problems because neither of them is automatically loaded and changing
the name is likely to break any setup that relies on manually loading
it by name.
As there is probably no sparc64 system with this kind of ancient joystick
attached, work around it by adding a Kconfig dependency that forbids
them from both being modules. It is still possible to build the joystick
driver if the sparc64 adi driver is built-in.

The replacement of <asm/pgrable.h> with <linux/pgtable.h> made the include
of the latter in the middle of asm includes. Fix this up with the aid of
the below script and manual adjustments here and there.
import sys
import re
if len(sys.argv) is not 3:
print "USAGE: %s <file> <header>" % (sys.argv[0])
sys.exit(1)
hdr_to_move="#include <linux/%s>" % sys.argv[2]
moved = False
in_hdrs = False
with open(sys.argv[1], "r") as f:
lines = f.readlines()
for _line in lines:
line = _line.rstrip('
')
if line == hdr_to_move:
continue
if line.startswith("#include <linux/"):
in_hdrs = True
elif not moved and in_hdrs:
moved = True
print hdr_to_move
print line
