We have many parser that register mtd partitions at runtime. One example
is the cmdlinepart or the smem-part parser where the compatible is defined
in the dts and the partitions gets detected and registered by the
parser. This is problematic for the NVMEM subsystem that requires an OF
node to detect NVMEM cells.
To fix this problem, introduce an additional logic that will try to
assign an OF node to the MTD if declared.
On MTD addition, it will be checked if the MTD has an OF node and if
not declared will check if a partition with the same label / node name is
declared in DTS. If an exact match is found, the partition dynamically
allocated by the parser will have a connected OF node.
The NVMEM subsystem will detect the OF node and register any NVMEM cells
declared statically in the DTS.

Document new partition nodes that declare only the label/name instead
of the reg used to provide an OF node for partition registred at runtime
by parsers. This is required for nvmem system to declare and detect
nvmem-cells.
With these special partitions, the reg / offset is not required and a
'partition-' prefix is needed.
The node name with the 'partition-' prefix stripped, is used to match
the partition allocated by the parser at runtime and the parser will
provide reg and offset of the mtd.
If the partition to match contains invalid char for a node name, the
label binding can be used to declare the partition name.
NVMEM will use the data from the parser and provide the NVMEM cells
declared in the DTS, "connecting" the dynamic partition with a
static declaration of cells in them.

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by adding an id_table listing the

mtdchar_write_ioctl() calls kmalloc() with the 'size' argument set to
the smaller of two values: the write request's data/OOB length provided
by user space and the erase block size of the MTD device. If the latter
is large, kmalloc() may not be able to serve such allocation requests.
Use kvmalloc() instead. Correspondingly, replace kfree() calls with
kvfree() calls.

Commit 6420ac0af95d ("mtdchar: prevent unbounded allocation in MEMWRITE
ioctl") added a safety check to mtdchar_write_ioctl() which attempts to
ensure that the write request sent by user space does not extend beyond
the MTD device's size. However, that check contains an addition of two
struct mtd_write_req fields, 'start' and 'len', both of which are u64
variables. The result of that addition can overflow, allowing the
safety check to be bypassed.
The arguably simplest fix - changing the data types of the relevant
struct mtd_write_req fields - is not feasible as it would break user
space.
Fix by making mtdchar_write_ioctl() truncate the value provided by user
space in the 'len' field of struct mtd_write_req, so that only the lower
32 bits of that field are used, preventing the overflow.
While the 'ooblen' field of struct mtd_write_req is not currently used
in any similarly flawed safety check, also truncate it to 32 bits, for
consistency with the 'len' field and with other MTD routines handling
OOB data.
Update include/uapi/mtd/mtd-abi.h accordingly.

There is a deadlock between sm_release and sm_cache_flush_work
which is a work item. The cancel_work_sync in sm_release will
not return until sm_cache_flush_work is finished. If we hold
mutex_lock and use cancel_work_sync to wait the work item to
finish, the work item also requires mutex_lock. As a result,
the sm_release will be blocked forever. The race condition is
shown below:
(Thread 1) | (Thread 2)
sm_release |
mutex_lock(&ftl->mutex) | sm_cache_flush_work
| mutex_lock(&ftl->mutex)
cancel_work_sync | ...
This patch moves del_timer_sync and cancel_work_sync out of
mutex_lock in order to mitigate deadlock.

delayacct: track delays from write-protect copy
The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

This contains the new HTE subsystem that has been in the works for a
couple of months now. The infrastructure provided allows for drivers to
register as hardware timestamp providers, while consumers will be able
to request events that they are interested in (such as GPIOs and IRQs)
to be timestamped by the hardware providers.
Note that this currently supports only one provider, but there seems to
be enough interest in this functionality and we expect to see more
drivers added once this is merged.

Merge tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux
Pull hardware timestamping subsystem from Thierry Reding:
"This contains the new HTE (hardware timestamping engine) subsystem
that has been in the works for a couple of months now.
The infrastructure provided allows for drivers to register as hardware
timestamp providers, while consumers will be able to request events
that they are interested in (such as GPIOs and IRQs) to be timestamped
by the hardware providers.
Note that this currently supports only one provider, but there seems
to be enough interest in this functionality and we expect to see more
drivers added once this is merged"
[ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake
platforms as another future timestamp provider ]
