Hi,
We have a desktop which has S3 suspend (to RAM) problem due to
error messages as follows.

Hello kernel devs,

Since the panic kdump functionality has been ready, this patch is to
hook panic callback function for ETB/ETF. Since the driver data
structure has allocated buffer when the session started, so simply save
ETB/ETF trace data into the buffer when panic happens and update

Add detailed documentation for Coresight panic kdump, which contains
the idea for why need this and introduce the framework implementation

When we use iounmap() to free the mapping, it calls unmap_vmap_area() to clear

Hi,
we are currently starting to use batman-adv as mesh protocol on multicore
embedded devices. These usually don't have a lot of CPU power per core but
are reasonable fast when using multiple cores.
It was noticed that sending was working very well but receiving was
basically only using on CPU c

The uapi headers use the __u8/__u16/... version of the fixed width types
instead of u8/u16/... The use of the latter must be avoided before

The batman-adv unicast packets contain a full layer 2 frame in encapsulated
form. The flow dissector must therefore be able to parse the batman-adv

The BIT(x) macro is no longer available for uapi headers because it is
defined outside of it (linux/bitops.h). The use of it must therefore be

The headers used by packet.h should also be included by it directly. main.h
is currently dealing with it in batman-adv, but this will no longer work

This patch series does the below
--> Fixes sparse warnings in the driver.
--> Fixes race conditions in the driver for cdma.
--> Fixes issues with the dma_get_slave_caps() API failures.
This patch series got created on top of below commit
in the slave-dma.git topic/xilinx branch.
"dmaengine: xilin
When client driver uses dma_get_slave_caps() api,
it checks for certain fields of dma_device struct
currently driver is not settings few fields resulting
dma_get_slave_caps() returning failure.
This patch fixes this issue by populating proper values
to the struct dma_device fields.

This patch fixes the below sparse warning in the driver
drivers/dma/xilinx/xilinx_dma.c: In function ‘xilinx_vdma_dma_prep_interleaved’:
drivers/dma/xilinx/xilinx_dma.c:1614:43: warning: variable ‘prev’ set but not

struct xilinx_vdma_tx_segment *segment, *prev =
when hardware is idle we need to toggle the SG bit
in the control register, inorder to update new value to the
current descriptor register other wise undefined
results will occur.
This patch updates the same.
