"This round of fixes has two larger changes that came in last week:
- a couple of patches all intended to finally turn on USB support on
various Amlogic SoC based boards. The respective driver were not
finalized until very late before the merge window and the DT
portion is the last bit now.
- a defconfig update for gemini that had repeatedly missed the cut
but that is required to actually boot any real machines with the
default build.
The rest are the usual small changes:
- a fix for a nasty build regression on the OMAP memory drivers
- a fix for a boot problem on Intel/Altera SocFPGA
- a MAINTAINER file update
- a couple of fixes for issues found by automated testing (kernelci,
coverity, sparse, ...)

mtd: rawnand: marvell: fix the chip-select DT parsing logic
The block responsible of parsing the DT for the number of chip-select
lines uses an 'if/else if/else if' block. The content of the second and
third 'else if' conditions are:
1/ the actual condition to enter the sub-block and
2/ the operation to do in this sub-block.
[...]
else if (condition1_to_enter && action1() == failed)
raise_error();
else if (condition2_to_enter && action2() == failed)
raise_error();
[...]
In case of failure, the sub-block is entered and an error raised.
Otherwise, in case of success, the code would continue erroneously in
the next 'else if' statement because it did not failed (and did not
enter the first 'else if' sub-block).
The first 'else if' refers to legacy bindings while the second 'else if'
refers to new bindings. The second 'else if', which is entered
erroneously, checks for the 'reg' property, which, for old bindings,
does not mean anything because it would not be the number of CS
available, but the regular register map of almost any DT node. This
being said, the content of the 'reg' property being the register map
offset and length, it has '2' values, so the number of CS in this
situation is assumed to be '2'.
When running nand_scan_ident() with 2 CS, the core will check for an
array of chips. It will first issue a RESET and then a READ_ID. Of
course this will trigger two timeouts because there is no chip in front
of the second CS:
[ 1.367460] marvell-nfc
f2720000.nand: Timeout on CMDD (NDSR: 0x00000080)
[ 1.474292] marvell-nfc
f2720000.nand: Timeout on CMDD (NDSR: 0x00000280)
Indeed, this is harmless and the core will then assume there is only one
valid CS.
Fix the logic in the whole block by entering each sub-block just on the
'is legacy' condition, doing the action inside the sub-block. This way,
when the action succeeds, the whole block is left.
Furthermore, for both the old bindings and the new bindings the same
logic was applied to retrieve the number of CS lines:
using of_get_property() to get a size in bytes, converted in the actual
number of lines by dividing it per sizeof(u32) (4 bytes).
This is fine for the 'reg' property which is a list of the CS IDs but
not for the 'num-cs' property which is directly the value of the number
of CS.
Anyway, no existing DT uses another value than 'num-cs = <1>' and no
other value has ever been supported by the old driver (pxa3xx_nand.c).
Remove this condition and apply a number of 1 CS anyway, as already
described in the bindings.
Finally, the 'reg' property of a 'nand' node (with the new bindings)
gives the IDs of each CS line in use. marvell_nand.c driver first look
at the number of CS lines that are present in this property.
Better use of_property_count_elems_of_size() than dividing by 4 the size
of the number of bytes returned by of_get_property().

HISI LPC: Add Kconfig MFD_CORE dependency
For ACPI support of the HiSilicon LPC driver we depend
on MFD_CORE config.
Currently the HiSi LPC Kconfig entry does not define this
dependency, so add it.
The reason for depending on MFD_CORE in the driver is
that we model the LPC host as an MFD, in that a platform
device will be created for each device on the bus.
We do this as we need to modify the resources of these
derived platform devices, something which we should not
do to the original devices created in the ACPI scan.

We're currently failing to reset everything in display_info.hdmi
which will potentially cause us to use stale information when

supports scrambling. That will lead to a black screen since the
HDMI 1.x monitor won't understand the scrambled signal.
Fix the problem by clearing display_info.hdmi fully. And while at

Revert "drm/sun4i: add lvds mode_valid function"
The reverted commit broke LVDS output on TBS A711 Tablet. That tablet
has simple-panel node that has fixed pixel clock-frequency that A83T
SoC used in the tablet can't generate exactly.
Requested rate is
52000000 and rounded_rate is calculated as
51857142.
It's close enough for it to work in practice, but with strict check
in the reverted commit, the mode is rejected needlessly in this case.
DT allows to specify a range of values for simple-panel/clock-frequency,
but driver doesn't respect that ATM. Given that TBS A711 is the single
user of sun4i-lvds driver, let's revert that commit for now, until
a better solution for the problem is found.

drm/amd/display: Disallow enabling CRTC without primary plane with FB
The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
Since DC is currently not equipped to handle this we need to fail such
a commit, otherwise we might see a corrupted screen.
This is based on Shirish's previous approach but avoids adding all
planes to the new atomic state which leads to a full update in DC for
any commit, and is not what we intend.
Theoretically DM should be able to deal with states with fully populated planes,
even for simple updates, such as cursor updates. This should still be
addressed in the future.

kprobes: Fix random address output of blacklist file
File /sys/kernel/debug/kprobes/blacklist displays random addresses:
[root@s8360046 linux]# cat /sys/kernel/debug/kprobes/blacklist
0x0000000047149a90-0x00000000bfcb099a print_type_x8
....
This breaks 'perf probe' which uses the blacklist file to prohibit
probes on certain functions by checking the address range.
Fix this by printing the correct (unhashed) address.
The file mode is read all but this is not an issue as the file
hierarchy points out:
# ls -ld /sys/ /sys/kernel/ /sys/kernel/debug/ /sys/kernel/debug/kprobes/
/sys/kernel/debug/kprobes/blacklist
dr-xr-xr-x 12 root root 0 Apr 19 07:56 /sys/
drwxr-xr-x 8 root root 0 Apr 19 07:56 /sys/kernel/
drwx------ 16 root root 0 Apr 19 06:56 /sys/kernel/debug/
drwxr-xr-x 2 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/
-r--r--r-- 1 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/blacklist
Everything in and below /sys/kernel/debug is rwx to root only,
no group or others have access.
Background:
Directory /sys/kernel/debug/kprobes is created by debugfs_create_dir()
which sets the mode bits to rwxr-xr-x. Maybe change that to use the
parent's directory mode bits instead?

tracing/x86: Update syscall trace events to handle new prefixed syscall func names
Arnaldo noticed that the latest kernel is missing the syscall event system
directory in x86. I bisected it down to
d5a00528b58c ("syscalls/core,
syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*()").
The system call trace events are special, as there is only one trace event
for all system calls (the raw_syscalls). But a macro that wraps the system
calls creates meta data for them that copies the name to find the system
call that maps to the system call table (the number). At boot up, it does a
kallsyms lookup of the system call table to find the function that maps to
the meta data of the system call. If it does not find a function, then that
system call is ignored.
Because the x86 system calls had "__x64_", or "__ia32_" prefixed to the
"sys" for the names, they do not match the default compare algorithm. As
this was a problem for power pc, the algorithm can be overwritten by the
architecture. The solution is to have x86 have its own algorithm to do the
compare and this brings back the system call trace events.

drm/i915/fbdev: Enable late fbdev initial configuration
If the initial fbdev configuration (intel_fbdev_initial_config()) runs
and there still no sink connected it will cause
drm_fb_helper_initial_config() to return 0 as no error happened (but
internally the return is -EAGAIN). Because no framebuffer was
allocated, when a sink is connected intel_fbdev_output_poll_changed()
will not execute drm_fb_helper_hotplug_event() that would trigger
another try to do the initial fbdev configuration.
So here allowing drm_fb_helper_hotplug_event() to be executed when there
is no framebuffer allocated and fbdev was not set up yet.
This issue also happens when a MST DP sink is connected since boot, as
the MST topology is discovered in parallel if
intel_fbdev_initial_config() is executed before the first sink MST is
discovered it will cause this same issue.
This is a follow-up patch of
https://patchwork.freedesktop.org/patch/196089/
Changes from v1:
- not creating a dump framebuffer anymore, instead just allowing
drm_fb_helper_hotplug_event() to execute when fbdev is not setup yet.

ACPI / video: Only default only_lcd to true on Win8-ready _desktops_
Commit
5928c281524f (ACPI / video: Default lcd_only to true on Win8-ready
and newer machines) made only_lcd default to true on all machines where
acpi_osi_is_win8() returns true, including laptops.
The purpose of this is to avoid the bogus / non-working acpi backlight
interface which many newer BIOS-es define on desktop machines.
But this is causing a regression on some laptops, specifically on the
Dell XPS 13 2013 model, which does not have the LCD flag set for its
fully functional ACPI backlight interface.
Rather then DMI quirking our way out of this, this commits changes the
logic for setting only_lcd to true, to only do this on machines with
a desktop (or server) dmi chassis-type.
Note that we cannot simply only check the chassis-type and not register
the backlight interface based on that as there are some laptops and
tablets which have their chassis-type set to "3" aka desktop. Hopefully
the combination of checking the LCD flag, but only on devices with
a desktop(ish) chassis-type will avoid the needs for DMI quirks for this,
or at least limit the amount of DMI quirks which we need to a minimum.

igb: Fix the transmission mode of queue 0 for Qav mode
When Qav mode is enabled, queue 0 should be kept on Stream Reservation
mode. From the i210 datasheet, section 8.12.19:
"Note: Queue0 QueueMode must be set to 1b when TransmitMode is set to
Qav." ("QueueMode 1b" represents the Stream Reservation mode)
The solution is to give queue 0 the all the credits it might need, so
it has priority over queue 1.
A situation where this can happen is when cbs is "installed" only on
queue 1, leaving queue 0 alone. For example:
$ tc qdisc replace dev enp2s0 handle 100: parent root mqprio num_tc 3 \

ACPI / button: make module loadable when booted in non-ACPI mode
Modules such as nouveau.ko and i915.ko have a link time dependency on
acpi_lid_open(), and due to its use of acpi_bus_register_driver(),
the button.ko module that provides it is only loadable when booted in
ACPI mode. However, the ACPI button driver can be built into the core
kernel as well, in which case the dependency can always be satisfied,
and the dependent modules can be loaded regardless of whether the
system was booted in ACPI mode or not.
So let's fix this asymmetry by making the ACPI button driver loadable
as a module even if not booted in ACPI mode, so it can provide the
acpi_lid_open() symbol in the same way as when built into the kernel.

ACPI / watchdog: Prefer iTCO_wdt on Lenovo Z50-70
WDAT table on Lenovo Z50-70 is using RTC SRAM (ports 0x70 and 0x71) to
store state of the timer. This conflicts with Linux RTC driver
(rtc-cmos.c) who fails to reserve those ports for itself preventing RTC
from functioning. In addition the WDAT table seems not to be fully
functional because it does not reset the system when the watchdog times
out.
On this system iTCO_wdt works just fine so we simply prefer to use it
instead of WDAT. This makes RTC working again and also results working
watchdog via iTCO_wdt.

amd-xgbe: Improve KR auto-negotiation and training
Update xgbe-phy-v2.c to make use of the auto-negotiation (AN) phy hooks
to improve the ability to successfully complete Clause 73 AN when running
at 10gbps. Hardware can sometimes have issues with CDR lock when the
AN DME page exchange is being performed.
The AN and KR training hooks are used as follows:
- The pre AN hook is used to disable CDR tracking in the PHY so that the
DME page exchange can be successfully and consistently completed.
- The post KR training hook is used to re-enable the CDR tracking so that
KR training can successfully complete.
- The post AN hook is used to check for an unsuccessful AN which will
increase a CDR tracking enablement delay (up to a maximum value).
Add two debugfs entries to allow control over use of the CDR tracking
workaround. The debugfs entries allow the CDR tracking workaround to
be disabled and determine whether to re-enable CDR tracking before or
after link training has been initiated.
Also, with these changes the receiver reset cycle that is performed during
the link status check can be performed less often.
