The split between the two flat.h files is completely arbitrary, and the
uapi version even contains CONFIG_ ifdefs that can't work in userspace.
The only userspace program known to use the header is elf2flt, and it
ships with its own version of the combined header.
Use the chance to move the <asm/flat.h> inclusion out of this file, as it
is in no way needed for the format defintion, but just for the binfmt
implementation.

SPI memory devices from different manufacturers have widely
different configurations for Status, Control and Configuration
registers. JEDEC 216C defines a new map for these common register
bits and their functions, and describes how the individual bits may
be accessed for a specific device. For the JEDEC 216B compliant
flashes, we can partially deduce Status and Configuration registers
functions by inspecting the 16th DWORD of BFPT. Older flashes that
don't declare the SFDP tables (SPANSION FL512SAIFG1 311QQ063 A ©11
SPANSION) let the software decide how to interact with these registers.
The commit dcb4b22eeaf4 ("spi-nor: s25fl512s supports region locking")
uncovered a probe error for s25fl512s, when the Quad Enable bit CR[1]
was set to one in the bootloader. When this bit is one, only the Write
Status (01h) command with two data byts may be used, the 01h command with
one data byte is not recognized and hence the error when trying to clear
the block protection bits.
Fix the above by using the Write Status (01h) command with two data bytes
when the Quad Enable bit is one.
Backward compatibility should be fine. The newly introduced
spi_nor_spansion_clear_sr_bp() is tightly coupled with the
spansion_quad_enable() function. Both assume that the Write Register
with 16 bits, together with the Read Configuration Register (35h)
instructions are supported.

Some changes to the TCP fastopen code to make it more robust
against future changes in the choice of key/cookie size, etc.
- Instead of keeping the SipHash key in an untyped u8[] buffer
and casting it to the right type upon use, use the correct
type directly. This ensures that the key will appear at the
correct alignment if we ever change the way these data
structures are allocated. (Currently, they are only allocated
via kmalloc so they always appear at the correct alignment)
- Use DIV_ROUND_UP when sizing the u64[] array to hold the
cookie, so it is always of sufficient size, even if
TCP_FASTOPEN_COOKIE_MAX is no longer a multiple of 8.
- Drop the 'len' parameter from the tcp_fastopen_reset_cipher()
function, which is no longer used.
- Add endian swabbing when setting the keys and calculating the hash,
to ensure that cookie values are the same for a given key and
source/destination address pair regardless of the endianness of
the server.
Note that none of these are functional changes wrt the current
state of the code, with the exception of the swabbing, which only
affects big endian systems.

This further unifies the accessors for the fast and coarse functions, so
that the same types of functions are available for each. There was also
a bit of confusion with the documentation, which prior advertised a
function that has never existed. Finally, the vanilla ktime_get_coarse()
was omitted from the API originally, so this fills this oversight.

Drivers may rely on pci_disable_link_state() having disabled certain
ASPM link states. If OS can't control ASPM then pci_disable_link_state()
turns into a no-op w/o informing the caller. The driver therefore may
falsely assume the respective ASPM link states are disabled.
Let pci_disable_link_state() propagate errors to the caller, enabling
the caller to react accordingly.

When CONFIG_IPV6 is disabled, the bridge netfilter code
produces a link error:
ERROR: "br_ip6_fragment" [net/bridge/netfilter/nf_conntrack_bridge.ko] undefined!
ERROR: "nf_ct_frag6_gather" [net/bridge/netfilter/nf_conntrack_bridge.ko] undefined!
The problem is that it assumes that whenever IPV6 is not a loadable
module, we can call the functions direction. This is clearly
not true when IPV6 is disabled.
There are two other functions defined like this in linux/netfilter_ipv6.h,
so change them all the same way.

The VMCI handle array has an integer overflow in
vmci_handle_arr_append_entry when it tries to expand the array. This can be
triggered from a guest, since the doorbell link hypercall doesn't impose a
limit on the number of doorbell handles that a VM can create in the
hypervisor, and these handles are stored in a handle array.
In this change, we introduce a mandatory max capacity for handle
arrays/lists to avoid excessive memory usage.

Currently both journal_submit_inode_data_buffers() and
journal_finish_inode_data_buffers() operate on the entire address space
of each of the inodes associated with a given journal entry. The
consequence of this is that if we have an inode where we are constantly
appending dirty pages we can end up waiting for an indefinite amount of
time in journal_finish_inode_data_buffers() while we wait for all the
pages under writeback to be written out.
The easiest way to cause this type of workload is do just dd from
/dev/zero to a file until it fills the entire filesystem. This can
cause journal_finish_inode_data_buffers() to wait for the duration of
the entire dd operation.
We can improve this situation by scoping each of the inode dirty ranges
associated with a given transaction. We do this via the jbd2_inode
structure so that the scoping is contained within jbd2 and so that it
follows the lifetime and locking rules for that structure.
This allows us to limit the writeback & wait in
journal_submit_inode_data_buffers() and
journal_finish_inode_data_buffers() respectively to the dirty range for
a given struct jdb2_inode, keeping us from waiting forever if the inode
in question is still being appended to.

sg_alloc_table_chained() currently allows the caller to provide one
preallocated SGL and returns if the requested number isn't bigger than
size of that SGL. This is used to inline an SGL for an IO request.
However, scattergather code only allows that size of the 1st preallocated
SGL to be SG_CHUNK_SIZE(128). This means a substantial amount of memory
(4KB) is claimed for the SGL for each IO request. If the I/O is small, it
would be prudent to allocate a smaller SGL.
Introduce an extra parameter to sg_alloc_table_chained() and
sg_free_table_chained() for specifying size of the preallocated SGL.
Both __sg_free_table() and __sg_alloc_table() assume that each SGL has the
same size except for the last one. Change the code to allow both functions
to accept a variable size for the 1st preallocated SGL.

In order to centralize the REQ_OP_XXX to string conversion which can be
used in the block layer and different places in the kernel like f2fs,
this patch adds a new helper function along with an array similar to the
one present in the blk-mq-debugfs.c.
We keep this helper functionality centralize under blk-core.c instead of
blk-mq-debugfs.c since blk-core.c is configured using CONFIG_BLOCK and
it will not be dependent on blk-mq-debugfs.c which is configured using
CONFIG_BLK_DEBUG_FS.
Next patch adjusts the code in the blk-mq-debugfs.c with newly
introduced helper.

are also removed. This will cause a change of behavior - nfs/afs will
NOT generate an fsnotify delete event when renaming over a positive
dentry. This change is desirable, because it is consistent with the
behavior of all other filesystems.

We would like to move fsnotify_nameremove() calls from d_delete()
into a higher layer where the hook makes more sense and so we can
consider every d_delete() call site individually.
Start by creating empty hook fsnotify_{unlink,rmdir}() and place
them in the proper VFS call sites. After all d_delete() call sites
will be converted to use the new hook, the new hook will generate the
delete events and fsnotify_nameremove() hook will be removed.

According to the DA9061 and DA9062 datasheets the LDO voltage selection
registers have a lower value of 0x02. This applies to voltage registers
VLDO1_A, VLDO2_A, VLDO3_A and VLDO4_A. This linear offset of 0x02 was
previously not observed by the driver, causing the LDO output voltage to
be systematically lower by two steps (= 0.1V).
This patch fixes the minimum linear selector offset by setting it to a
value of 2 and increases the n_voltages by the same amount allowing
voltages in the range 0x02 -> 0.9V to 0x38 -> 3.6V to be correctly
selected. Also fixes an incorrect calculaton for the n_voltages value in
the regulator LDO2.
These fixes effect all LDO regulators for DA9061 and DA9062.

The Cirrus Logic Madera codecs are a family of related codecs with
extensive digital and analogue I/O, digital mixing and routing,
signal processing and programmable DSPs. This patch adds common
support code shared by all Madera codecs.
This patch also adds the pdata to the parent mfd pdata struct.
Since there is a circular build dependency it's convenient to
patch them both atomically.

__data_len and __sector are internal fields which should not be accessed
directly in driver-level like the comment above it. But, tag field can
be accessed by driver level directly so that we need to make the comment
right by moving it to some other place.

On ioremap(), __ioremap_check_mem() does a couple of checks on the
supplied memory range to determine how the range should be mapped and in
particular what protection flags should be used.
Generalize the procedure by introducing IORES_MAP_* flags which control
different aspects of the ioremapping and use them in the respective
helpers which determine which descriptor flags should be set per range.

When executing the kexec_file_load() syscall, the first kernel needs to
pass the e820 reserved ranges to the second kernel because some devices
(PCI, for example) need them present in the kdump kernel for proper
initialization.
But the kernel can not exactly match the e820 reserved ranges when
walking through the iomem resources using the default IORES_DESC_NONE
descriptor, because there are several types of e820 ranges which are
marked IORES_DESC_NONE, see e820_type_to_iores_desc().
Therefore, add a new I/O resource descriptor called IORES_DESC_RESERVED
to mark exactly those ranges. It will be used to match the reserved
resource ranges when walking through iomem resources.

The i3c bus spec defines a bus configuration where i2c devices don't
have a 50ns filter but support SCL running at SDR max rate (12.5MHz).
This patch introduces the limited bus mode so that users can use
a higher speed in presence of i2c devices index 1.

So far we have reused the name of the "platform" device for
the CoreSight device. But this is not very intuitive when
we move to ACPI. Also, the ACPI device names have ":" in them
(e.g, ARMHC97C:01), which the perf tool doesn't like very much.
This patch introduces a generic naming scheme, givin more intuitive
names for the devices that appear on the CoreSight bus.
The names follow the pattern "prefix" followed by "index" (e.g, etm5).
We maintain a list of allocated devices per "prefix" to make sure
we don't allocate a new name when it is reprobed (e.g, due to
unsatisifed device dependencies). So, we maintain the list
of "fwnodes" of the parent devices to allocate a consistent name.
All devices except the ETMs get an index allocated in the order
of probing. ETMs get an index based on the CPU they are attached to.
TMC devices are named using "tmc_etf", "tmc_etb", and "tmc_etr"
prefixes depending on the configuration of the device.
The replicators and funnels are not classified as dynamic/static
anymore. One could easily figure that out by checking the presence
of "mgmt" registers under sysfs.

We rely on the device names to find a CoreSight device on the
coresight bus. The device name however is obtained from the platform,
which is bound to the real platform/amba device. As we are about
to use different naming scheme for the coresight devices, we can't
rely on the platform device name to find the corresponding
coresight device. Instead we use the platform agnostic
"fwnode handle" of the parent device to find the devices.
We also reuse the same fwnode as the parent for the Coresight
device we create.
