Yes, I think there can be 2 problems.
1. distance table may be filled with incorrect data.
2. numactl -H distance table shows symmetric data, the symmetric nature may
be lost.

We follow the same steps when fetching distance information. Instead of
using affinity domain id, we now use the mapped node id. The relevant
hunk in the patch is
+ nid = affinity_domain_to_nid(&domain);
if (nid > 0 &&
- of_read_number(associativity, 1) >= distance_ref_points_depth) {
+ of_read_number(associativity, 1) >= distance_ref_points_depth) {
/*
* Skip the length field and send start of associativity array
*/
I haven't tried dlpar add/remove. I don't have a setup to try that. Do
you see a problem there?

I have picked patches from your tree to adapt to this new API.
Those can be picked in 5.10 I suppose.

Commit 12cc923f1ccc ("tasklet: Introduce new initialization API")'
introduced a new tasklet initialization API. This series converts
all the sound drivers to use the new tasklet_setup() API
Allen Pais (10):
sound: core: convert tasklets to use new tasklet_setup() API
sound: firewire: convert tasklets to use new tasklet_setup() API
sound: asihpi: convert tasklets to use new tasklet_setup() API
sound: riptide: convert tasklets to use new tasklet_setup() API
sound: rm9652: convert tasklets to use new tasklet_setup() API
sound/soc: fsl_esai: convert tasklets to use new tasklet_setup() API
sound/soc: sh: convert tasklets to use new tasklet_setup() API
sound/soc: txx9: convert tasklets to use new tasklet_setup() API
sound: midi: convert tasklets to use new tasklet_setup() API
sound: ua101: convert tasklets to use new tasklet_setup() API

In-Reply-To: <20200817085409.25268-1-allen.cryptic@gmail.com>
From: Allen Pais <allen.lkml@gmail.com>
In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
