The sheet music used to generate the tones had a few
polyphonic notes. Due to that, its conversion to a
tones sequence had a few errors.
Also, due to a bug at the tone generator, it was missing
the pause at the initial compass.
Fix them.
While here, reduce the compass to 100bpm.
The music was converted from a Music XML file using
this small script:
<snip>
my $count = 0;
my $silent = 0;
my $note;
my $octave;
print "\t";
while (<>) {

}

tls_device_offload_cleanup_rx doesn't clear tls_ctx->netdev after
calling tls_dev_del if TLX TX offload is also enabled. Clearing
tls_ctx->netdev gets postponed until tls_device_gc_task. It leaves a
time frame when tls_device_down may get called and call tls_dev_del for
RX one extra time, confusing the driver, which may lead to a crash.
This patch corrects this racy behavior by adding a flag to prevent
tls_device_down from calling tls_dev_del the second time.

Two earlier bug fixes have created a security problem in the hfi1
driver. One fix aimed to solve an issue where current->mm was not valid
when closing the hfi1 cdev. It attempted to do this by saving a cached
value of the current->mm pointer at file open time. This is a problem if
another process with access to the FD calls in via write() or ioctl() to
pin pages via the hfi driver. The other fix tried to solve a use after
free by taking a reference on the mm.
To fix this correctly we use the existing cached value of the mm in the
mmu notifier. Now we can check in the insert, evict, etc. routines that
current->mm matched what the notifier was registered for. If not, then
don't allow access. The register of the mmu notifier will save the mm
pointer.
Since in do_exit() the exit_mm() is called before exit_files(), which
would call our close routine a reference is needed on the mm. We rely on
the mmgrab done by the registration of the notifier, whereas before it was
explicit. The mmu notifier deregistration happens when the user context is
torn down, the creation of which triggered the registration.
Also of note is we do not do any explicit work to protect the interval
tree notifier. It doesn't seem that this is going to be needed since we
aren't actually doing anything with current->mm. The interval tree
notifier stuff still has a FIXME noted from a previous commit that will be
addressed in a follow on patch.

The tc-taprio base time indicates the beginning of the tc-taprio
schedule, which is cyclic by definition (where the length of the cycle
in nanoseconds is called the cycle time). The base time is a 64-bit PTP
time in the TAI domain.
Logically, the base-time should be a future time. But that imposes some
restrictions to user space, which has to retrieve the current PTP time
from the NIC first, then calculate a base time that will still be larger
than the base time by the time the kernel driver programs this value
into the hardware. Actually ensuring that the programmed base time is in
the future is still a problem even if the kernel alone deals with this.
Luckily, the enetc hardware already advances a base-time that is in the
past into a congruent time in the immediate future, according to the
same formula that can be found in the software implementation of taprio
(in taprio_get_start_time):
/* Schedule the start time for the beginning of the next
* cycle.
*/
n = div64_s64(ktime_sub_ns(now, base), cycle);
*start = ktime_add_ns(base, (n + 1) * cycle);
There's only one problem: the driver doesn't let the hardware do that.
It interferes with the base-time passed from user space, by special-casing
the situation when the base-time is zero, and replaces that with the
current PTP time. This changes the intended effective base-time of the
schedule, which will in the end have a different phase offset than if
the base-time of 0.000000000 was to be advanced by an integer multiple
of the cycle-time.

When spectre_v2_user={seccomp,prctl},ibpb is specified on the command
line, IBPB is force-enabled and STIPB is conditionally-enabled (or not
available).
However, since
21998a3515 ("x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS.")
the spectre_v2_user_ibpb variable is set to SPECTRE_V2_USER_{PRCTL,SECCOMP}
instead of SPECTRE_V2_USER_STRICT, which is the actual behaviour.
Because the issuing of IBPB relies on the switch_mm_*_ibpb static
branches, the mitigations behave as expected.
Since
1978b3a53a ("x86/speculation: Allow IBPB to be conditionally enabled on CPUs with always-on STIBP")
this discrepency caused the misreporting of IB speculation via prctl().
On CPUs with STIBP always-on and spectre_v2_user=seccomp,ibpb,
prctl(PR_GET_SPECULATION_CTRL) would return PR_SPEC_PRCTL |
PR_SPEC_ENABLE instead of PR_SPEC_DISABLE since both IBPB and STIPB are
always on. It also allowed prctl(PR_SET_SPECULATION_CTRL) to set the IB
speculation mode, even though the flag is ignored.
Similarly, for CPUs without SMT, prctl(PR_GET_SPECULATION_CTRL) should
also return PR_SPEC_DISABLE since IBPB is always on and STIBP is not
available.

all allocations are recorded in a linked list, and freed when the

by David, leads to crashes if SLUB is configured to self destruct when
double frees occur.
So drop the redundant kfree() again, and instead, mark the offending

Combined UART (TCU) driver or the Tegra 8250 driver. By default, the
TCU will use UARTC on Jetson Xavier NX. Currently, device-tree for
Xavier NX enables the TCU and the Tegra 8250 node for UARTC. Fix this
by disabling the Tegra 8250 node for UARTC and enabling the Tegra 8250
node for UARTA.

Commit ff4c371d2b ("arm64: defconfig: Build ADMA and ACONNECT driver")
enable the Tegra ADMA and ACONNECT drivers and this is causing resume
from system suspend to fail on Jetson TX2. Resume is failing because the
ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT
driver is attempting to power on a power-domain that is provided by the
BPMP. While a proper fix for the resume sequencing problem is identified,
disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system
suspend.
Please note that ACONNECT driver is used by the Audio Processing Engine
(APE) on Tegra, but because there is no mainline support for APE on
Jetson TX2 currently, disabling the ACONNECT does not disable any useful
feature at the moment.

When SPI DW memory ops support was introduced, there was a check for
excluding controllers which supplied their own CS function. Even so,
the mem_ops pointer is *always* presented to the SPI core.
This causes the SPI core sanity check in spi_controller_check_ops() to
refuse registration, since a mem_ops pointer is being supplied without
an exec_op member function.
The end result is failure of the SPI DW driver on sparx5 and similar
platforms.
The fix in the core SPI DW driver is to avoid presenting the mem_ops
pointer if the exec_op function is not set.

After commit 327d5b2fee ("iommu/vt-d: Allow 32bit devices to uses DMA
domain"), swiotlb could also be used for direct memory access if IOMMU
is enabled but a device is configured to pass through the DMA translation.
Keep swiotlb when IOMMU is forced on, otherwise, some devices won't work
if "iommu=pt" kernel parameter is used.

The bdi_dev_name() returns a char [64], and
the __entry->name is a char [32].
It maybe dangerous to TP_printk("%s", __entry->name)

Only in smp systems the cache policy is setup as write alloc, in
single cpu systems the cache policy is set as writeback and it is
normal memory, so, it should pass the is_normal_memory check in the
share memory registration.
Add the right condition to make it work in no smp systems.

The gamma LUT has to be reloaded after changing the primary plane's
color format. This used to be done implicitly by the CRTC atomic_enable()
helper after updating the primary plane. With the recent reordering of
the steps, the primary plane's setup was moved last and invalidated
the gamma LUT. Fix this by setting the LUT from within atomic_flush().

Based on the discussion with Sukadev Bhattiprolu and Dany Madden,
we believe that checking adapter->resetting bit is preferred
since RESETTING state flag is not as strict as resetting bit.
RESETTING state flag is removed since it is verbose now.
