commit 2d691aeca4 upstream.
set_page_dirty says:
For pages with a mapping this should be done under the page lock
for the benefit of asynchronous memory errors who prefer a
consistent dirty state. This rule can be broken in some special
cases, but should be better not to.
Under those rules, it is only safe for us to use the plain set_page_dirty
calls for shmemfs/anonymous memory. Userptr may be used with real
mappings and so needs to use the locked version (set_page_dirty_lock).
However, following a try_to_unmap() we may want to remove the userptr and
so call put_pages(). However, try_to_unmap() acquires the page lock and
so we must avoid recursively locking the pages ourselves -- which means
that we cannot safely acquire the lock around set_page_dirty(). Since we
can't be sure of the lock, we have to risk skip dirtying the page, or
else risk calling set_page_dirty() without a lock and so risk fs
corruption.

commit d791cfcbf9 upstream.
When we hot unplug a virtserialport and then try to hot plug again,
it fails:
(qemu) chardev-add socket,id=serial0,path=/tmp/serial0,server,nowait
(qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\
chardev=serial0,id=serial0,name=serial0
(qemu) device_del serial0
(qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\
chardev=serial0,id=serial0,name=serial0
kernel error:
virtio-ports vport2p2: Error allocating inbufs
qemu error:
virtio-serial-bus: Guest failure in adding port 2 for device \
virtio-serial0.0
This happens because buffers for the in_vq are allocated when the port is
added but are not released when the port is unplugged.
They are only released when virtconsole is removed (see a7a69ec0d8)
To avoid the problem and to be symmetric, we could allocate all the buffers
in init_vqs() as they are released in remove_vqs(), but it sounds like
a waste of memory.
Rather than that, this patch changes add_port() logic to ignore ENOSPC
error in fill_queue(), which means queue has already been filled.

commit b0391479ae upstream.
When converting milliseconds to microseconds in commit fffa6af948
("gpio: max77620: Use correct unit for debounce times") some ~1 ms gaps
were introduced between the various ranges supported by the controller.
Fix this by changing the start of each range to the value immediately
following the end of the previous range. This way a debounce time of,
say 8250 us will translate into 16 ms instead of returning an -EINVAL
error.
Typically the debounce delay is only ever set through device tree and
specified in milliseconds, so we can never really hit this issue because
debounce times are always a multiple of 1000 us.
The only notable exception for this is drivers/mmc/host/mmc-spi.c where
the CD GPIO is requested, which passes a 1 us debounce time. According
to a comment preceeding that code this should actually be 1 ms (i.e.
1000 us).

[ Upstream commit 1fc1657775 ]
The helper mlxsw_sp_ipip_dev_ul_tb_id() determines the underlay VRF of a
GRE tunnel. For a tunnel without a bound device, it uses the same VRF that
the tunnel is in. However in Linux, a GRE tunnel without a bound device
uses the main VRF as the underlay. Fix the function accordingly.
mlxsw further assumed that moving a tunnel to a different VRF could cause
conflict in local tunnel endpoint address, which cannot be offloaded.
However, the only way that an underlay could be changed by moving the
tunnel device itself is if the tunnel device does not have a bound device.
But in that case the underlay is always the main VRF, so there is no
opportunity to introduce a conflict by moving such device. Thus this check
constitutes a dead code, and can be removed, which do.

[ Upstream commit 52eb74339a ]
rdt_find_domain() returns an ERR_PTR() that is generated from a provided
domain id when the value is negative.
Care needs to be taken when creating an ERR_PTR() from this value
because a subsequent check using IS_ERR() expects the error to
be within the MAX_ERRNO range. Using an invalid domain id as an
ERR_PTR() does work at this time since this is currently always -1.
Using this undocumented assumption is fragile since future users of
rdt_find_domain() may not be aware of thus assumption.
Two related issues are addressed:
- Ensure that rdt_find_domain() always returns a valid error value by
forcing the error to be -ENODEV when a negative domain id is provided.
- In a few instances the return value of rdt_find_domain() is just
checked for NULL - fix these to include a check of ERR_PTR.

the state that lldpad_app_wait_set() typically sees, and since there are
no pending entries at that time, it bails out. However the entries have
not been pushed to the kernel yet at that point, and thus the test case
fails.
Fix by waiting for both unknown and pending entries to disappear before
proceeding.

The three INA3221_CONFIG_MODE macros are not correctly defined here.
The MODE3-1 bits are located at BIT 2-0 according to the datasheet.
So this patch just fixes them by shifting all of them with a correct
offset. However, this isn't a crital bug fix as the driver does not
use any of them at this point.

BIOS developer guides refer to Family 15h Models 60h-6fh and Family 15h
Models 70h-7fh. So far the driver only checked for Models 60h and 70h.
However, there are now processors with other model numbers in the same
families. Example is A10-9620P family 15h model 65h. Follow the developer
guides and mask the lower 4 bit of the model number to determine the
registers to use for reading temperatures and temperature limits.

The previous fix made the TVC clock get muxed in on the
D-Link DIR-685 instead of giving nagging warnings of this
not working. Not good. We didn't want that, as it breaks
video.
Create a specific group for the TVC CLK, and break out
a specific GPIO group for it on the SL3516 so we can use
that line as GPIO if we don't need the TVC CLK.

[ Upstream commit c200dac78f ]
PCI BIOS requires the BIOS area 0x0A0000-0x0FFFFFF to be mapped W+X for
various legacy reasons. When CONFIG_DEBUG_WX is enabled, this triggers the
WX warning, but this is misleading because the mapping is required and is
not a result of an accidental oversight.
Prevent the full warning when PCI BIOS is enabled and the detected WX
mapping is in the BIOS area. Just emit a pr_warn() which denotes the
fact. This is partially duplicating the info which the PCI BIOS code emits
when it maps the area as executable, but that info is not in the context of
the WX checking output.
Remove the extra %p printout in the WARN_ONCE() while at it. %pS is enough.

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.
