[Xen-devel] [PATCH v2 0/7] xen/arm: TLB flush helpers rework

[Julien Grall <julien.grall@xxxxxxx>]

Hi all,

I spent the last few months looking at Xen boot and memory management to make
it simpler, more efficient and also more compliant in respect of the Arm Arm.

The full rework is quite consequence (already 150 patches and I haven't yet
finished!), so I am planning to send in smaller part over the next few weeks.

In this first part, I focus on reworking how we flush the TLBs in Xen.

Cheers,

Julien Grall (7):
  xen/arm: mm: Consolidate setting SCTLR_EL2.WXN in a single place
  xen/arm: Remove flush_xen_text_tlb_local()
  xen/arm: tlbflush: Clarify the TLB helpers name
  xen/arm: page: Clarify the Xen TLBs helpers name
  xen/arm: Gather all TLB flush helpers in tlbflush.h
  xen/arm: tlbflush: Rework TLB helpers
  xen/arm: mm: Flush the TLBs even if a mapping failed in
    create_xen_entries
