I'm testing you patches. At first glance everything is fine, no obvious
regressions.

But I've found an ARC build issue with the latest upstream source
(tag: v6.7-rc5). It is not linked with your updates.
The build issue occurs when the CONFIG_TRANSPARENT_HUGEPAGE option
is enabled:

| ../fs/proc/task_mmu.c: In function ‘pagemap_scan_thp_entry’:
| ../fs/proc/task_mmu.c:2115:28: error: ‘HPAGE_SIZE’ undeclared (first use in this function); did you mean ‘PAGE_SIZE’?
|  2115 |         if (end != start + HPAGE_SIZE) {
|       |                            ^~~~~~~~~~
|       |                            PAGE_SIZE
| ../fs/proc/task_mmu.c:2115:28: note: each undeclared identifier is reported only once for each function it appears in
| make[4]: *** [../scripts/Makefile.build:243: fs/proc/task_mmu.o] Error 1
| make[3]: *** [../scripts/Makefile.build:480: fs/proc] Error 2

May be you could address this issue in your updates too?

Thanks
Pavel
