Merge series from David Lechner <dlechner@baylibre.com>:
I found a couple more controller drivers that were checking if the
tx_buf and rx_buf fields in the spi_transfer structure were set by a
peripheral driver that I missed in [1]. These checks can be removed
as well.

Merge series from Louis Chauvet <louis.chauvet@bootlin.com>:
This series adds the support for the omap-mcspi multi mode which allows
sending SPI messages with a shorter delay between CS and the message.
One drawback of the multi-mode is that the CS is raised between each word,
so it can only be used with messages containing 1 word transfers and
asking for cs_change. Few devices, like FPGAs, may easily workaround this
limitation.
The first patch removes the current implementation, which is working, but
don't comply with what is asked in the spi transfer (The CS is raised by
the hardware regardless of cs_change state). No drivers or board file use this
implementation upstream.
The second patch adds the implementation of the multi-mode, which complies
with what is asked in the SPI message.
The third patch is the suggested optimization for using MULTI mode in more
situations.

There are no more peripheral drivers that set t->tx_dma or t->rx_dma.
Therefore, is_dma_mapped is always false and can be removed.

The PCI || ACPI dependency is the historical part of the x86 support.
Narrow the Kconfig option visibility by limiting this dependency to x86.
The drop of x86 for PCI case had happened in the commit 2b49ebda39d6
("spi/pxa2xx: allow building on a 64-bit kernel"), while the ACPI
was specifically added for Intel Lynx Point in the commit a3496855d9f1
("spi/pxa2xx: add support for Lynxpoint SPI controllers").
Note that X86 covers both 32- and 64-bit variants.

Enable multimode when a transfer of multiple small words can be

Introduce support for MULTI-mode in the OMAP2 MCSPI driver. Currently, the
driver always uses SINGLE mode to handle the chip select (CS). With this
enhancement, MULTI-mode is enabled for specific messages, allowing for a
shorter delay between CS enable and the message (some FPGA devices are
sensitive to this delay).
The OMAP2 MCSPI device can use two different mode to send messages, SINGLE
and MULTI:
In SINGLE mode, the controller only leverages one single FIFO, and the
host system has to manually select the CS it wants to enable.
In MULTI mode, each CS is bound to a FIFO, the host system then writes the
data to the relevant FIFO, as the hardware will take care of the CS
The drawback of multi-mode is that it's not possible to keep the CS
enabled between each words. Therefore, this patch enables multi-mode only
for specific messages: the spi_message must contain only spi_transfer of 1
word (of any size) with cs_change enabled.
A new member is introduced in the omap2_mcspi structure to keep track of
the current used mode.

Commit 5cbc7ca987fb ("spi: spi-omap2-mcspi.c: Toggle CS after each
word") introduced the toggling of CS after each word for the omap2-mcspi
controller.
The implementation is not respectful of the actual spi_message
content, so the CS can be raised after each word even if the
transfer structure asks to keep the CS active for the whole operation.
As it is not used anyway in the current Linux tree, it can be safely
removed.

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:
A couple of cleanups against linux/spi/pxa2xx_spi.h.
I'm sending this as v3 to land in the SPI subsystem. Meanwhile I'm
preparing an update to make linux/spi/pxa2xx_spi.h private to the
subsystem (PXA2xx driver). But the second part will be presented later
on (likely after v6.9-rc1). That said, this can be routed either via
SoC tree or SPI, up to respective maintainers.

Add support to the SPI controller driver to use SPI MEM framework.
SPI subsystem utilizing the SPI memory operations allows to re-use
SPI controller drivers for both SPI NOR devices, regular SPI devices
as well as SPI NAND devices.
Add below functions of spi_mem_ops to support SPI MEM framework
- exec-op(): to execute the memory operations.
- supports_op(): to check if the memory operation is supported.
- adjust_op_size(): to split data transfers so that they don’t exceed the
max transfer size supported by the controller.

Extract a magic number, from mt7621_spi_probe(), used to
declare the number of chip select lines (which co-incides
with the native chip select count of 2) to a macro.
Use the newly defined MT7621_NATIVE_CS_COUNT macro to
instead populate both the spi_controller's max_native_cs
and num_chipselect members.
Declare that the spi_controller should use_gpio_descriptors
if present in the device properties (such as those declared
in the cs-gpio property of a "ralink,mt7621-spi" compatible
device-tree node) so that the SPI core will recalculcate
num_chipselect to account for the GPIO descriptors that
it should have populated in the cs_gpiod array member.
Remove the assignment of mt7621_spi_transfer_one_message()
to the spi_controller's transfer_one_message hook.
Refactor the mt7621_spi_transfer_one_message() logic into
mt7621_spi_prepare_message() and mt7621_spi_transfer_one()
and assign both to the spi_controller's prepare_message
and transfer_one hooks respectively.
Migrate the call mt7621_spi_transfer_one_message() made to
mt7621_spi_flush() just before chip select deactivation,
to the end of mt7621_spi_write_half_duplex() to ensure
that any pending data is shifted out of MOSI before the SPI
core deactivates the chip select line.
As chip select activation is now taken care of by the SPI
core, due to the use of the transfer_one hook instead of
transfer_one_message, the calls to mt7621_spi_set_cs()
from mt7621_spi_transfer_one_message() have fallen away.
And although the SPI core will handle activation for GPIO
chip select lines behind the scenes, it requires a callback
to allow the driver to perform controller-specific
operations to control its native chip select lines.
Rename mt7621_spi_set_cs() to mt7621_spi_set_native_cs()
and make sure that it takes into account the activation
polarity of the chip select line it's acting upon, as the
passed enable parameter represents the desired line level
and not the desired activation state, and then assign
mt7621_set_cs() to the spi_controller's set_cs hook.

Clearing BSS should only be done once, at the very beginning.
efi_pe_entry() is the entrypoint from the firmware, which may not clear
BSS and so it is done explicitly. However, efi_pe_entry() is also used
as an entrypoint by the mixed mode startup code, in which case BSS will
already have been cleared, and doing it again at this point will corrupt
global variables holding the firmware's GDT/IDT and segment selectors.
So make the memset() conditional on whether the EFI stub is running in
native mode.

More recently the SCSI based UFS (Universal Flash Storage) drivers
have wanted to take advantage of this as well, for the same reasons as
f2fs, necessitating plumbing the write hints through the block layer
and then adding it to the SCSI core.
The vfs write_hints already taken plumbs this as far as block and this

higher address
Following warning is sometimes observed while booting my servers:
[ 3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations
[ 3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1
...
[ 3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation
If 'nokaslr' boot option is set, the warning always happens.
On x86, ZONE_DMA is small zone at the first 16MB of physical address
space. When this problem happens, most of that space seems to be used by
decompressed kernel. Thereby, there is not enough space at DMA_ZONE to
meet the request of DMA pool allocation.
The commit 2f77465b05b1 ("x86/efistub: Avoid placing the kernel below
LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower
bound of allocation.
But the fix is not complete.
efi_random_alloc() allocates pages by following steps.
1. Count total available slots ('total_slots')
2. Select a slot ('target_slot') to allocate randomly
3. Calculate a starting address ('target') to be included target_slot
4. Allocate pages, which starting address is 'target'
In step 1, 'alloc_min' is used to offset the starting address of memory
chunk. But in step 3 'alloc_min' is not considered at all. As the
result, 'target' can be miscalculated and become lower than 'alloc_min'.
When KASLR is disabled, 'target_slot' is always 0 and the problem
happens everytime if the EFI memory map of the system meets the
condition.
Fix this problem by calculating 'target' considering 'alloc_min'.

- ipv4: raw: fix sending packets from raw sockets via IPsec tunnels
- devlink: fix devlink's parallel command processing
- veth: do not manipulate GRO when using XDP
- esp: fix bad handling of pages from page_pool
