[ Upstream commit 3522f867c13b63cf62acdf1b8ca5664c549a716a ]
acpi_ec.gpe is "unsigned long", hence treating it as "u32" would expose
the wrong half on big-endian 64-bit systems. Fix this by changing its
type to "u32" and removing the cast, as all other code already uses u32
or sometimes even only u8.

[ Upstream commit ebe2f8718007d5a1238bb3cb8141b5bb2b4d5773 ]
The ACPI specification says OS shouldn't attempt to use GICC configuration
parameters if the flag ACPI_MADT_ENABLED is cleared. The ARM64-SMP code
skips the disabled GICC entries but not causing any issue. However the
current GICv3 driver probe bails out causing kernel panic() instead of
skipping the disabled GICC interfaces. This issue happens on systems
where redistributor regions are not in the always-on power domain and
one of GICC interface marked with ACPI_MADT_ENABLED=0.
This patch does the two things to fix the panic.
- Don't return an error in gic_acpi_match_gicc() for disabled GICC entry.
- No need to keep GICR region information for disabled GICC entry.
Observed kernel crash on QDF2400 platform GICC entry is disabled.

[ Upstream commit f49d4aed1315a7b766d855f1367142e682b0cc87 ]
1. In IO path, setting of "ATA command pending" flag early before device
removal, invalid device handle etc., checks causes any new commands
to be always returned with SAM_STAT_BUSY and when the driver removes
the drive the SML issues SYNC Cache command and that command is
always returned with SAM_STAT_BUSY and thus making SYNC Cache command
to requeued.
2. If the driver gets an ATA PT command for a SATA drive then the driver
set "ATA command pending" flag in device specific data structure not
to allow any further commands until the ATA PT command is completed.
However, after setting the flag if the driver decides to return the
command back to upper layers without actually issuing to the firmware
(i.e., returns from qcmd failure return paths) then the corresponding
flag is not cleared and this prevents the driver from sending any new
commands to the drive.
This patch fixes above two issues by setting of "ATA command pending"
flag after checking for whether device deleted, invalid device handle,
device busy with task management. And by setting "ATA command pending"
flag to false in all of the qcmd failure return paths after setting the
flag.

[ Upstream commit d754941225a7dbc61f6dd2173fa9498049f9a7ee ]
If, for any reason, userland shuts down iscsi transport interfaces
before proper logouts - like when logging in to LUNs manually, without
logging out on server shutdown, or when automated scripts can't
umount/logout from logged LUNs - kernel will hang forever on its
sd_sync_cache() logic, after issuing the SYNCHRONIZE_CACHE cmd to all
still existent paths.

This happens because iscsi_eh_cmd_timed_out(), the transport layer
timeout helper, would tell the queue timeout function (scsi_times_out)
to reset the request timer over and over, until the session state is
back to logged in state. Unfortunately, during server shutdown, this
might never happen again.
Other option would be "not to handle" the issue in the transport
layer. That would trigger the error handler logic, which would also need
the session state to be logged in again.
Best option, for such case, is to tell upper layers that the command was
handled during the transport layer error handler helper, marking it as
DID_NO_CONNECT, which will allow completion and inform about the
problem.
After the session was marked as ISCSI_STATE_FAILED, due to the first
timeout during the server shutdown phase, all subsequent cmds will fail
to be queued, allowing upper logic to fail faster.

[ Upstream commit 89434c3c35081439627baa2225622d5bd12242fe ]
When using RX (with or without TX), the DMA interrupt triggers
completion when the RX FIFO has been emptied, i.e. after the full
transfer has finished.
However, when using TX without RX, the DMA interrupt triggers completion
as soon as the DMA engine has filled the TX FIFO, i.e. before the full
transfer has finished. Then sh_msiof_modify_ctr_wait() will spin until
the transfer has really finished and the TFSE bit is cleared, for at
most 1 ms. For slow speeds and/or large transfers, this may cause
timeouts and transfer failures:
spi_sh_msiof e6e10000.spi: failed to shut down hardware
74x164 spi2.0: SPI transfer failed: -110
spi_master spi2: failed to transfer one message from queue
74x164 spi2.0: Failed writing: -110
Fix this by waiting explicitly until the TX FIFO has been emptied.
Based on a patch in the BSP by Hiromitsu Yamasaki.

[ Upstream commit 9dcfbc182f1aac0aa5ea194733d21e67dd2ba1fd ]
The msm/kms driver should work even if there is no GPU device specified
in DT. Currently, we get a NULL dereference crash in adreno_load_gpu
since the driver assumes that priv->gpu_pdev is non-NULL.
Perform an additional check on priv->gpu_pdev before trying to retrieve
the msm_gpu pointer from it.
v2: Incorporate Jordan's comments:
- Simplify the check to share the same error message.
- Use dev_err_once() to avoid an error message every time we open the
drm device fd.

[ Upstream commit b70b309950418437bbd2a30afd169c4f09dee3e5 ]
Various Cherry Trail boards with a rt5645 codec have an analog mic
connected to IN2P + IN2N. The mic on this boards also needs micbias to
be enabled, on some boards micbias1 is used and on others micbias2, so
we enable both.
This commit adds a new "Int Analog Mic" DAPM widget for this, so that we
do not end up enabling micbias on boards with a digital mic which uses
the already present "Int Mic" widget. Some existing UCM files already
refer to "Int Mic" for their "Internal Analog Microphones" SectionDevice,
but these don't work anyways since they enable the RECMIX BST1 Switch
instead of the BST2 switch.

even if it is processed after -D, src/dst address initialization
should not require that [-4|-6] be specified before
the -S or -D args, receiver should be able to bind to *.<cfg_port>
Achieve this by making sure that the address/port structures
are initialized after all command line options are parsed.
Store cfg_port in host-byte order, and use htons()
to set up the sin_port/sin6_port before bind/connect,
so that the network system calls get the correct values
in network-byte order.

[ Upstream commit 8234af2db3614d78b49e77ef46ea8cfab6586568 ]
Update the offload flag, TCQ_F_OFFLOADED, in each dump call (and ignore
the offloading function return value in relation to this flag).
This is done because a qdisc is being initialized, and therefore offloaded
before being grafted. Since the ability of the driver to offload the qdisc
depends on its location, a qdisc can be offloaded and un-offloaded by graft
calls, that doesn't effect the qdisc itself.

[ Upstream commit 12a26c298d2a8b1cab498533fa65198e49e3afd3 ]
divider_recalc_rate() is an helper function used by clock divider of
different types, so the structure containing the 'hw' pointer is not
always a 'struct clk_divider'
At the following line:
> div = _get_div(table, val, flags, divider->width);
in several cases, the value of 'divider->width' is garbage as the actual
structure behind this memory is not a 'struct clk_divider'
Fortunately, this width value is used by _get_val() only when
CLK_DIVIDER_MAX_AT_ZERO flag is set. This has never been the case so
far when the structure is not a 'struct clk_divider'. This is probably
why we did not notice this bug before

The only way of stopping the watchdog is by resetting it.
Add the watchdog op for stopping the device and reset if
a reset line is provided.
At same time WDOG_HW_RUNNING should be remove from dw_wdt_start.
As commented by Guenter Roeck:
dw_wdt sets WDOG_HW_RUNNING in its open function. Result is
that the kref_get() in watchdog_open() won't be executed. But then
kref_put() in close will be called since the watchdog now does stop.
This causes the imbalance.

[ Upstream commit 61647823aa920e395afcce4b57c32afb51456cab ]
d_move() will call __d_drop() and then __d_rehash()
on the dentry being moved. This creates a small window
when the dentry appears to be unhashed. Many tests
of d_unhashed() are made under ->d_lock and so are safe
from racing with this window, but some aren't.
In particular, getcwd() calls d_unlinked() (which calls
d_unhashed()) without d_lock protection, so it can race.
This races has been seen in practice with lustre, which uses d_move() as
part of name lookup. See:
https://jira.hpdd.intel.com/browse/LU-9735
It could race with a regular rename(), and result in ENOENT instead
of either the 'before' or 'after' name.
The race can be demonstrated with a simple program which
has two threads, one renaming a directory back and forth
while another calls getcwd() within that directory: it should never
fail, but does. See:
https://patchwork.kernel.org/patch/9455345/
We could fix this race by taking d_lock and rechecking when
d_unhashed() reports true. Alternately when can remove the window,
which is the approach this patch takes.
___d_drop() is introduce which does *not* clear d_hash.pprev
so the dentry still appears to be hashed. __d_drop() calls
___d_drop(), then clears d_hash.pprev.
__d_move() now uses ___d_drop() and only clears d_hash.pprev
when not rehashing.

[ Upstream commit 5928c281524fe451114e04f1dfa11246a37e859f ]
We're seeing a lot of bogus backlight interfaces on newer machines without
a LCD such as desktops, servers and HDMI sticks. This causes userspace to
show a non-functional brightness slider in e.g. the GNOME3 system menu,
which is undesirable. And, in general, we should simply just not register
a non functional backlight interface.
Checking the LCD flag causes the bogus acpi_video backlight interfaces to
go away (on the machines this was tested on).
This change sets the lcd_only option by default on any machines which
are Win8-ready, to fix this.
This is not entirely without a risk of regressions, but video_detect.c
already prefers native-backlight interfaces over the acpi_video one
on Win8-ready machines, calling acpi_video_unregister_backlight() as soon
as a native interface shows up. This is done because the ACPI backlight
interface often is broken on Win8-ready machines, because win8 does not
seem to actually use it.
So in practice we already end up not registering the ACPI backlight
interface on (most) Win8-ready machines with a LCD panel, thus this
change does not change anything for (most) machines with a LCD panel
and on machines without a LCD panel we actually don't want to register
any backlight interfaces.
This has been tested on the following machines and fixes a bogus backlight
interface showing up there:
- Desktop with an Asrock B150M Pro4S/D3 m.b. using i5-6500 builtin gfx
- Intel Compute Stick STK1AW32SC
- Meegopad T08 HDMI stick
Bogus backlight interfaces have also been reported on:
- Desktop with Asus H87I-Plus m.b.
- Desktop with ASRock B75M-ITX m.b.
- Desktop with Gigabyte Z87-D3HP m.b.
- Dell PowerEdge T20 desktop

[ Upstream commit ca8000684ec4e66f965e1f9547a3c6cb834154ca ]
While monitoring a multithread process with pid option, perf sometimes
may return sys_perf_event_open failure with 3(No such process) if any of
the process's threads die before we open the event. However, we want
perf continue monitoring the remaining threads and do not exit with
error.
Here, the patch enables perf_evsel::ignore_missing_thread for -p option
to ignore complete failure if any of threads die before we open the event.
But it may still return sys_perf_event_open failure with 22(Invalid) if we
monitors several event groups.
sys_perf_event_open: pid 28960 cpu 40 group_fd 118202 flags 0x8
sys_perf_event_open: pid 28961 cpu 40 group_fd 118203 flags 0x8
WARNING: Ignored open failure for pid 28962
sys_perf_event_open: pid 28962 cpu 40 group_fd [118203] flags 0x8
sys_perf_event_open failed, error -22
That is because when we ignore a missing thread, we change the thread_idx
without dealing with its fds, FD(evsel, cpu, thread). Then get_group_fd()
may return a wrong group_fd for the next thread and sys_perf_event_open()
return with 22.
sys_perf_event_open(){
...
if (group_fd != -1)
perf_fget_light()//to get corresponding group_leader by group_fd
...
if (group_leader)
if (group_leader->ctx->task != ctx->task)//should on the same task
goto err_context
...
}
This patch also fixes this bug by introducing perf_evsel__remove_fd() and
update_fds to allow removing fds for the missing thread.
Changes since v1:
- Change group_fd__remove() into a more genetic way without changing code logic
- Remove redundant condition
Changes since v2:
- Use a proper function name and add some comment.
- Multiline comment style fixes.
Committer testing:
Before this patch the recently added 'perf stat --per-thread' for system
wide counting would race while enumerating all threads using /proc:
[root@jouet ~]# perf stat --per-thread
failed to parse CPUs map: No such file or directory
Usage: perf stat [<options>] [<command>]
-C, --cpu <cpu> list of cpus to monitor in system-wide
-a, --all-cpus system-wide collection from all CPUs
[root@jouet ~]# perf stat --per-thread
failed to parse CPUs map: No such file or directory
Usage: perf stat [<options>] [<command>]
-C, --cpu <cpu> list of cpus to monitor in system-wide
-a, --all-cpus system-wide collection from all CPUs
[root@jouet ~]#
When, say, the kernel was being built, so lots of shortlived threads,
after this patch this doesn't happen.

[ Upstream commit f9d8adb345d7adbb2d3431eea73beb89c8d6d612 ]
When we detect a different endianity we swap event before processing.
It's tricky for samples because we have no idea what's inside. We treat
it as an array of u64s, swap them and later on we swap back parts which
are different.
We mangle this way also the tracepoint raw data, which ends up in report
showing wrong data:
1.95% comm=Q^B pid=29285 prio=16777216 target_cpu=000
1.67% comm=l^B pid=0 prio=16777216 target_cpu=000
Luckily the traceevent library handles the endianity by itself (thank
you Steven!), so we can pass the RAW data directly in the other
endianity.
2.51% comm=beah-rhts-task pid=1175 prio=120 target_cpu=002
2.23% comm=kworker/0:0 pid=11566 prio=120 target_cpu=000
The fix is basically to swap back the raw data if different endianity is
detected.

[ Upstream commit 0a03f98b98c201191e3ba15a0e33f46d8660e1fd ]
This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device
to the btusb blacklist and makes the kernel use the btqca module
instead of btusb. The patch is necessary because, without it the
04ca:3015 device defaults to using the btusb driver, which makes the
WIFI side of the QCA9377 board unusable (obtains 0 MBps in speedtest,
when the 04ca:3015 bluetooth is used with an audio headset).

Commit a22950c888e3 (mmc: sdhci-of-esdhc: add quirk
SDHCI_QUIRK_BROKEN_TIMEOUT_VAL for ls1021a) added logic to the driver to
enable the broken timeout val quirk for ls1021a, but did not add the
corresponding compatible string to the device tree, so it didn't really
have any effect. Fix that.

[ Upstream commit 86aacdca66774051cbc0958110a48074b57a060b ]
"rem * SDM_DEN" can easily overflow on the 32-bit Meson8 and Meson8b
SoCs if the "remainder" (after the division operation) is greater than
262143Hz. This is likely to happen since the input clock for the MPLLs
on Meson8 and Meson8b is "fixed_pll", which is running at a rate of
2550MHz.
One example where this was observed to be problematic was the Ethernet
clock calculation (which takes MPLL2 as input). When requesting a rate
of 125MHz there is a remainder of 2500000Hz.
The resulting MPLL2 rate before this patch was 127488329Hz.
The resulting MPLL2 rate after this patch is 124999103Hz.
Commit b609338b26f5 ("clk: meson: mpll: use 64bit math in
rate_from_params") already fixed a similar issue in rate_from_params.

This reverts commit 813b2dad2cb59d2759f1538e65d56dcccdb18a94 which is
commit 53c81e95df1793933f87748d36070a721f6cb287 upstream.
Ben writes that there are a number of follow-on patches needed to fix
this up, but they get complex to backport, and some custom fixes are
needed, so let's just revert this and wait for a "real" set of patches
to resolve this to be submitted if it is really needed.
