Re: [OS-BUILD PATCHv3] Enable CONFIG_DMA_NUMA_CMA for x86_64 and aarch64

See https://issues.redhat.com/browse/RHEL-59621 Ok, so it seems that some enterprise customers have custom network cards which actually require physically contiguous memory on x86_64. And they are using this in big x86_64 machines with a NUMA setup and want to specify per NUMA node CMA buffers for performance reasons. So I guess that this is fine, but can we have something like the above in the commit message please ? Maybe even with the issues.redhat.com link, although that link will only be readable by Red Hat folks.

[OS-BUILD PATCHv2] CONFIG_OF_OVERLAY: enable for aarch64 and powerpc
by Scott Weaver (via Email Bridge) 02 Oct '24

02 Oct '24

From: Scott Weaver <scweaver(a)redhat.com> CONFIG_OF_OVERLAY: enable for aarch64 and powerpc CONFIG_OF_OVERLAY is now selected by some KUnit tests where CONFIG_OF is enabled. Because these tests are enabled for aarch64 and powerpc we also need to enable CONFIG_OF_OVERLAY for these arches. See: 5776526beb95 ('clk: Add KUnit tests for clk fixed rate basic type') 274aff8711b2 ('clk: Add KUnit tests for clks registered with struct clk_parent_data') 5c9dd72d8385 (of: Add a KUnit test for overlays and test managed APIs) This consolidates CONFIG_OF_OVERLAY now that we're enabling it for all arches that support it.
