But first update usage sites with the new header dependency.

ktime: Cleanup ktime_set() usage

2016-12-25T16:21:22+00:00

ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

dmaengine: dmatest: honor alignment restriction for buffers

2016-11-30T03:20:18+00:00

Existing implementation does not honor the alignment restrictions imposed
by the DMA engines. Allocate buffers with built in slack for honoring
alignment restrictions. Creating new arrays to hold the aligned pointers
and use those pointers for operations.

dmaengine: dmatest: Restore "memcpy" as default mode

2016-09-15T15:47:58+00:00

Commit 0d4cb44da6ca0e8 ("dmaengine: dmatest: Add support for
scatter-gather DMA mode") changes default "dmatest" behavior by
changing default mode from "memcpy" to "scatter-gather".
Now "memcpy" gets back as default mode.

dmaengine: dmatest: Apply copy_align to DMA_SG as well

2016-09-09T11:40:54+00:00

The DMA_SG is still a type of memory copy operation that should
conform the hardware restriction. So this patch just applies the
copy_align to DMA_SG as well.

dmaengine: dmatest: exclude compare and fill time during perf report

2016-09-02T11:07:04+00:00

Dmatest is currently including compare and fill time into the
calculated performance numbers. This does not reflect the HW
capability and the results vary based on the CPU speed instead of
the HW speed.

kernel/params: constify struct kernel_param_ops uses

2015-05-28T02:02:10+00:00

Most code already uses consts for the struct kernel_param_ops,
sweep the kernel for the last offending stragglers. Other than
include/linux/moduleparam.h and kernel/params.c all other changes
were generated with the following Coccinelle SmPL patch. Merge
conflicts between trees can be handled with Coccinelle.

In the future git could get Coccinelle merge support to deal with
patch --> fail --> grammar --> Coccinelle --> new patch conflicts
automatically for us on patches where the grammar is available and
the patch is of high confidence. Consider this a feature request.

dmatest: move src_off, dst_off, len inside loop

2015-02-05T02:17:21+00:00

The scope of those varsiables is in while-loop. This patch moves them there and
removes duplicate code.
