This is a preparation patch before adding the DW DMA support into the
DW SPI MMIO driver. We need to unpin the Non-DMA-specific code from the
intended to be generic DW APB SSI DMA code. This isn't that hard,
since the most part of the spi-dw-mid.c driver in fact implements a
generic DMA interface
Generic DMA support is going to be part of the DW APB SSI core object.
In order to preserve the kernel loadable module name as spi-dw.ko, let's
add the "-core" suffix to the object with generic DW APB SSI code and
build it into the target spi-dw.ko driver.
Signed-off-by: Serge Semin
Seeing DW APB SSI controller doesn't support setting the exactly
requested SPI bus frequency, but only a rounded frequency determined
by means of the odd-numbered half-worded reference clock divider,
it would be good to tune the SPI core up and initialize the current
transfer effective_speed_hz.
Since DMA transfers are performed asynchronously with actual SPI bus
transfers, then even if DMA transactions are finished it doesn't mean
all data is actually pushed to the SPI bus. Some data might still be
in the controller FIFO. This is specifically true for Tx-only transfers.
In this case if
Each channel of DMA controller may have a limited length of burst
transaction (number of IO operations performed at ones in a single
DMA client request). This parameter can be used to setup the most
optimal DMA Tx/Rx data level values. In order to avoid the Tx buffer
overrun we can set the DMA Tx
In general each DMA-based SPI transfer can be split up into two stages:
DMA data transmission/reception and SPI-bus transmission/reception. DMA
asynchronous transactions completion can be tracked by means of the
DMA async Tx-descriptor completion callback. But that callback being
called indicates

Add a helper to directly set the SCTP_NODELAY sockopt from kernel space
without going through a fake uaccess.

Split out a sctp_setsockopt_bindx_kernel that takes a kernel pointer
to the sockaddr and make sctp_setsockopt_bindx a small wrapper around
it. This prepares for adding a new bind_add proto op.

Hi Dave and Marcelo,
now that only the dlm calls to sctp are left for kernel_setsockopt,
while we haven't really made much progress with the sctp setsockopt
refactoring, how about this small series that splits out a
sctp_setsockopt_bindx_kernel that takes a kernel space address array
to share
The SCTP protocol allows to bind multiple address to a socket. That
feature is currently only exposed as a socket option. Add a bind_add
method struct proto that allows to bind additional addresses, and
switch the dlm code to use the method instead of going through the
socket option from kernel

Move random_table sysctl from kernel/sysctl.c to drivers/char/random.c
and use register_sysctl_subdir() to help remove the clutter out of
kernel/sysctl.c.

Move the firmware config sysctl table to fallback_table.c and use the
new register_sysctl_subdir() helper. This removes the clutter from
kernel/sysctl.c.

Hi Benoit,
Thank you for the patch.

By default we set -mcpu=xxx compiler flag depending on the CPU ISA
version. It's good starting point, however that may be not enough
as for some platforms we may want to use some specific 'mcpu'
options for better optimization or to workaround HW issues.
We are going to use this option for
Eugeniy Paltsev (3):
ARC: allow to overide default mcpu compiler flag
ARC: ARCv2: support loop buffer (LPB) disabling
ARC: [plat-hsdk-4xd] initial port for HSDK-4xD board
