[LSF/MM/BPF TOPIC] page table reclaim (David Hildenbrand) https://lkml.kernel.org/r/7b908208-02f8-6fde-4dfc-13d5e00310a6@redhat.com
Some workloads allocates a lot of page tables. As page tables are unmovable and unreclaimable, this can contribute to memory pressure. David is proposing making it reclaimable and suggesting discussion in LSF/MM/BPF summit for the idea.

[PATCH v2 1/2] arm64: avoid flushing icache multiple times on contiguous HugeTLB (Muchun Song) https://lkml.kernel.org/r/20220208054632.66534-1-songmuchun@bytedance.com
When a contiguous HugeTLB page is mapped, set_pte_at() is called CONT_PTES / CONT_PMDS times. Because the first flushing covers subsequent flushes, this is unnecessary overhead, so this patchset avoids it.

Users who want to use ksft_exit() need to figure out the internals of kselftest. This commit adds a helper function for that purpose, namely, ksft_finished().
[LSF/MM/BPF TOPIC] Handling of VMAs (Liam Howlett) https://lkml.kernel.org/r/20220201150521.owa5axfsmpdvc7uo@revolver
Liam is pointing out the VMAs are quite complicately managed with their cache, tree, linked list, and even reverse mapping. As it now shows its limit with the lock contention and complexity of the handling code, he wants to propose a simpler new way for their management.
[PATCH 0/7] Allocate module text and data separately (Christophe Leroy) https://lkml.kernel.org/r/cover.1643015752.git.christophe.leroy@csgroup.eu
Powerpc book3s/32 can set execute permission in 256 MiB segments granularity instead of page granularity. This patchset therefore allow module data be allocated in vmalloc rea instead of module area.
