commit 99b3b837855b987563bcfb397cf9ddd88262814b upstream.
There is a case found when triggering a panic_on_oom, pstore fails to dump
kmsg. Because psz_kmsg_write_record can't get the new buffer.
Handle this by using GFP_ATOMIC to allocate a buffer at lower watermark.

commit beca3e311a49cd3c55a056096531737d7afa4361 upstream.
If mem-type is specified in the device tree
it would end up overriding the record_size
field instead of populating mem_type.
As record_size is currently parsed after the
improper assignment with default size 0 it
continued to work as expected regardless of the
value found in the device tree.
Simply changing the target field of the struct
is enough to get mem-type working as expected.

[ Upstream commit 3d57f36c89d8ba32b2c312f397a37fd1a2dc7cfc ]
I no longer work for Plantronics (aka Poly, aka HP) and do not have
access to the headsets in order to test. However, as noted by Maxim,
the other 32xx models that share the same base code set as the 3220
would need the same quirk. This patch adds the PIDs for the rest of
the Blackwire 32XX product family that require the quirk.
Plantronics Blackwire 3210 Series (047f:c055)
Plantronics Blackwire 3215 Series (047f:c057)
Plantronics Blackwire 3225 Series (047f:c058)
Quote from previous patch by Maxim Mikityanskiy
Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice
for each volume key press. This patch adds a quirk to hid-plantronics
for this product ID, which will ignore the second volume key press if
it happens within 5 ms from the last one that was handled.
The patch was tested on the mentioned model only, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected, because the
rate is about 3 times per second, which is far less frequent than once
in 5 ms.

The HID descriptor of this device contains two mouse collections, one
for mouse emulation and the other for the trackpoint.
Both collections get merged and, because the first one defines X and Y,
the movemenent events reported by the trackpoint collection are
ignored.
Set the MT_CLS_WIN_8_FORCE_MULTI_INPUT class for this device to be able
to receive its reports.
This fix is similar to/based on commit 40d5bb87377a ("HID: multitouch:

[ Upstream commit ed2213bfb192ab51f09f12e9b49b5d482c6493f3 ]
rtas_os_term() is called during panic. Its behavior depends on a couple
of conditions in the /rtas node of the device tree, the traversal of
which entails locking and local IRQ state changes. If the kernel panics
while devtree_lock is held, rtas_os_term() as currently written could
hang.
Instead of discovering the relevant characteristics at panic time,
cache them in file-static variables at boot. Note the lookup for
"ibm,extended-os-term" is converted to of_property_read_bool() since it
is a boolean property, not an RTAS function token.

==================================================================
Kernel will tries to read record and parse MFT from disk in
ntfs_read_mft().
Yet the problem is that during enumerating attributes in record,
kernel doesn't check whether run_off field loading from the disk
is a valid value.
To be more specific, if attr->nres.run_off is larger than attr->size,
kernel will passes an invalid argument run_buf_size in
run_unpack_ex(), which having an integer overflow. Then this invalid
argument will triggers the slab-out-of-bounds Read bug as above.
This patch solves it by adding the sanity check between
the offset to packed runs and attribute size.

Since kernel 5.3.4 my laptop (ICH8M controller) does not see Kingston
SV300S37A60G SSD disk connected into a SATA connector on wake from
suspend. The problem was introduced in c312ef176399 ("libata/ahci: Drop
PCS quirk for Denverton and beyond"): the quirk is not applied on wake
from suspend as it originally was.
It is worth to mention the commit contained another bug: the quirk is
not applied at all to controllers which require it. The fix commit
09d6ac8dc51a ("libata/ahci: Fix PCS quirk application") landed in 5.3.8.
So testing my patch anywhere between commits c312ef176399 and
09d6ac8dc51a is pointless.
Not all disks trigger the problem. For example nothing bad happens with
Western Digital WD5000LPCX HDD.
Test hardware:
- Acer 5920G with ICH8M SATA controller
- sda: some SATA HDD connnected into the DVD drive IDE port with a
SATA-IDE caddy. It is a boot disk
- sdb: Kingston SV300S37A60G SSD connected into the only SATA port

Commit c312ef176399 dropped ahci_pci_reset_controller() which internally

ahci_reset_controller(). This patch puts the function back in place.

This is because in scatterwalk_copychunks(), we attempted to write to
a buffer (@sign) that was allocated in the stack (vmalloc area) by
crypt_message() and thus accessing its remaining 8 (x2) bytes ended up
crossing a page boundary.
To simply fix it, we could just pass @sign kmalloc'd from
crypt_message() and then we're done. Luckily, we don't seem to pass
any other vmalloc'd buffers in smb_rqst::rq_iov...
Instead, let's map the correct pages and offsets from vmalloc buffers
as well in cifs_sg_set_buf() and then avoiding such oopses.

added an optional Type-C interface to the driver but missed to check

devices currently using the old extcon interface. Check if a Type-C

commit 162d053e15fe985f754ef495a96eb3db970c43ed upstream.
If we get -ENOMEM while dropping file extent items in a given range, at
btrfs_drop_extents(), due to failure to allocate memory when attempting to
increment the reference count for an extent or drop the reference count,
we handle it with a BUG_ON(). This is excessive, instead we can simply
abort the transaction and return the error to the caller. In fact most
callers of btrfs_drop_extents(), directly or indirectly, already abort
the transaction if btrfs_drop_extents() returns any error.
Also, we already have error paths at btrfs_drop_extents() that may return
-ENOMEM and in those cases we abort the transaction, like for example
anything that changes the b+tree may return -ENOMEM due to a failure to
allocate a new extent buffer when COWing an existing extent buffer, such
as a call to btrfs_duplicate_item() for example.
So replace the BUG_ON() calls with proper logic to abort the transaction
and return the error.
