The SBI SRST extension provides a standard way to poweroff and
reboot the system irrespective to whether Linux RISC-V S-mode
is running natively (HS-mode) or inside Guest/VM (VS-mode).
The draft specification of SBI SRST extension is available in
srbt_v1 branch of: https://github.com/avpatel/riscv
Use kobj_to_dev() instead of container_of().

dump_unreclaimable_slab() acquires the slab_mutex first,
and it won't remove any slab_caches list entry when
itering the slab_caches lists.
Thus, we do not need list_for_each_entry_safe here,
which is against removal of list entry.

While the system heap can return non-contiguous pages,
try to allocate larger order pages if possible.
This will allow slight performance gains and make implementing

Hey All,
So this patch series contains a series of performance
optimizations to the dma-buf system heap.
Unfortunately, in working these up, I realized the heap-helpers
infrastructure we tried to add to miniimize code duplication is
not as generic as we intended. For some heaps it makes sense to
The heap-helpers code was not as generic as initially hoped
and it is now not being used, so remove it from the tree.

In preparation for some patches to optmize the system
heap code, rework the dmabuf exporter to utilize sgtables rather
then pageslists for tracking the associated pages.
This will allow for large order page allocations, as well as
more efficient page pooling.
In doing so, the system heap stops us
Since the heap-helpers logic ended up not being as generic as
hoped, move the heap-helpers dma_buf_ops implementations into
the cma_heap directly.
This will allow us to remove the heap_helpers code in a following

Sorry this thread is deep! Good news is I have moved the proximity
thresholds, hysteresis, hardware gain, and debounce to userspace. Now
just to figure out this filter strength.

Only function traces can be exported to other destinations currently.
This patch exports event trace as well. Move trace export related
function to the beginning of file so other trace can call
trace_process_export() to export.

Ftrace has ability to export trace packets to other destination.
Currently, only function trace can be exported. This series extends the

Add flag for difference traces, so that they can be controlled
