On a multiplatform kernel there is little benefit in splitting each
clock driver per platform because space savings are minimal. Such split
also complicates the code, especially after adding compile testing.
Build all arm64 Intel SoCFPGA clocks together with one entry in
Makefile. This also
The Intel's eASIC N5X (ARCH_N5X) architecture shares a lot with Agilex
(ARCH_AGILEX) so it uses the same socfpga_agilex.dtsi, with minor
changes. Also the clock drivers are the same.
However the clock drivers won't be build without ARCH_AGILEX. One could
assume that ARCH_N5X simply depends on

So make it a void function.

Hi,
All three Intel arm64 SoCFPGA architectures (Agilex, N5X and Stratix 10)
are basically flavors/platforms of the same architecture. At least from
the Linux point of view. Up to a point that N5X and Agilex share DTSI.
Having three top-level architectures for the same one barely makes
sense
The Stratix 10 / Agilex / N5X clocks do not use anything other than OF
or COMMON_CLK so they should be compile testable on most of the
platforms.

In the past, we clear dirty log immediately after sync dirty
log to userspace. This may cause redundant dirty handling if
userspace handles dirty log iteratively:
After vfio clears dirty log, new dirty log starts to generate.
These new dirty log will be reported to userspace
From: jiangkunkun
Block descriptor is not a proper granule for dirty log tracking.
Take an extreme example, if DMA writes one byte, under 1G mapping,
the dirty amount reported to userspace is 1G, but under 4K mapping,
the dirty amount is just 4K.
This adds a new interface named start_dirty_log
From: jiangkunkun
We have implemented these interfaces required to support iommu
dirty log tracking. The last step is reporting this feature to
upper user, then the user can perform higher policy base on it.
This adds a new dev feature named IOMMU_DEV_FEAT_HWDBM in iommu
layer. For arm smmuv3,

When stop dirty log tracking, we need to recover all block descriptors
which are splited when start dirty log tracking.

After dirty log is retrieved, user should clear dirty log to re-enable
dirty log tracking for these dirtied pages.

From: jiangkunkun
We are going to optimize dirty log tracking based on iommu
HWDBM feature, but the dirty log from iommu is useful only
when all iommu backed groups are connected to iommu with
HWDBM feature. This maintains a counter for this feature.

This series introduces a bulk order-0 page allocator with sunrpc and
the network page pool being the first users. The implementation is not
particularly efficient and the intention is to iron

Reduce the rate at which nfsd threads hammer on the page allocator.
This improve throughput scalability by enabling the threads to run
more independently of each other.

Refactor:
I'm about to use the loop variable @i for something else.
As far as the "i++" is concerned, that is a post-increment. The
value of @i is not used subsequently, so the increment operator
is unnecessary and can be removed.
Also note that nfsd_read_actor() was renamed
This patch adds a new page allocator interface via alloc_pages_bulk,
and __alloc_pages_bulk_nodemask. A caller requests a number of pages
to be allocated and added to a list. They can be freed in bulk using
free_pages_bulk().
The API is not guaranteed to return the requested number of pages and
From: Jesper Dangaard Brouer
There are cases where the page_pool need to refill with pages from the
page allocator. Some workloads cause the page_pool to release pages
instead of recycling these pages.
For these workload it can improve performance to bulk alloc pages from
the page-allocator to
The plane size needs to be PAGE_ALIGNED, so it is not possible to have
sizes bigger than MAX_INT - PAGE_SIZE.
We already check for overflows when that happen:

But it is good to explicitly state our max allowed value, in order to
align with
