On at least x86 and ARM64, and as documented in the ptrace man page
a skipped system call will still cause a syscall exit ptrace stop.
Previous to this commit 32-bit ARM did not, resulting in strace
being confused when seccomp skips system calls.
This change also impacts programs that use ptrace to skip system calls.

[ Upstream commit 605b3bec73cbd74b4ac937b580cd0b47d1300484 ]
spidev will make a big fuss if a device tree node binds a device by
using "spidev" as the node's compatible property.
However, the logic for this isn't looking for "spidev" in the
compatible, but rather checking that the device is NOT compatible with
spidev's list of devices.
This causes a false positive if a device not named "rohm,dh2228fv", etc.
binds to spidev, even if a means other than putting "spidev" in the
device tree was used. E.g., the sysfs driver_override attribute.

The code was written under the assumption that the
regmap_update_bits() would mask the bits in the mask and
set the bits in the value.
It missed the points that it will not set bits in the value
unless these are also masked in the mask. Set value bits
that are not in the mask will simply be ignored.

Certain devices don't work well when a transmit FIFO underrun or
receive FIFO overrun occurs. Example is the SAF400x radio chip when
running at high speed which leads to garbage being sent to/received from

available before proceeding. This patch unset the NOSTALL bit in CFGR1

The only use of KEXEC_BACKUP_SRC_END is as an argument to
walk_system_ram_res():
int crash_load_segments(struct kimage *image)
{
...
walk_system_ram_res(KEXEC_BACKUP_SRC_START, KEXEC_BACKUP_SRC_END,
image, determine_backup_region);
walk_system_ram_res() expects "start, end" arguments that are inclusive,
i.e., the range to be walked includes both the start and end addresses.
KEXEC_BACKUP_SRC_END was previously defined as (640 * 1024UL), which is the
first address *past* the desired 0-640KB range.
Define KEXEC_BACKUP_SRC_END as (640 * 1024UL - 1) so the KEXEC_BACKUP_SRC
region is [0-0x9ffff], not [0-0xa0000].

Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set. Fix this by casting value[3] to a u32 before
the shift.

Flushing the workqueue can cause operations to happen which might
call gfs2_log_reserve(), or get stuck waiting for locks taken by such
operations. gfs2_log_reserve() can io_schedule(). If this happens, it
will never wake because the only thing which can wake it is gfs2_logd()
which was already stopped.
This causes umount of a gfs2 filesystem to wedge permanently if, for
example, the umount immediately follows a large delete operation.

[ Upstream commit a26ac6c1bed951b2066cc4b2257facd919e35c0b ]
In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.
This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

A similar race existed when removing the sbs module with regards to

We therefore need to ensure no callbacks are pending or executing before
the cleanups are done and the modules are removed.

Instead of checking for the passed in open context against
the file lock's open context. Check that the state is the same.

clk_notifier_register() documentation states, that the provided notifier
callbacks associated with the notifier must not re-enter into the clk
framework by calling any top-level clk APIs. Fix this by replacing
clk_get_rate() calls with clk_hw_get_rate(), which is safe in this
context.

[ Upstream commit fbf07000960d9c8a13fdc17c6de0230d681c7543 ]
The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.
This change fixes WFA p2p certification 5.1.19 failure.

[ Upstream commit edb6d6885bef82d1eac432dbeca9fbf4ec349d7e ]
Finding a common channel to send an action frame out is required for
some action types. Since a loop with several scan retry is used to find
the channel, a short wait time could be considered for each attempt.
This patch reduces the wait time from 1500 to 450 msec for each action
frame scan.
This patch fixes the WFA p2p certification 5.1.20 failure caused by the
long action frame send time.

When an OS (currently only classic Mac OS) is running in KVM-PR and makes a
linked jump from code with split hack addressing enabled into code that does
not, LR is not correctly updated and reflects the previously munged PC.
To fix this, this patch undoes the address munge when exiting split
hack mode so that code relying on LR being a proper address will now
execute. This does not affect OS X or other operating systems running
on KVM-PR.
