[0/7] xen/arm: TLB flush helpers rework

Message

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: Gather all TLB flush helpers in tlbflush.h
