SRU Justification:
[Impact]
AWS discovered an issue of long EC2 instance launch times on the upcoming R8g instance types.
[Fix]
They have identified the following fixes that address this issue:
* https://patchew.org/linux/20240412131908.433043-1-ryan.roberts@arm.com/20240412131908.433043-2-ryan.roberts@arm.com/
* https://patchew.org/linux/20240412131908.433043-1-ryan.roberts@arm.com/20240412131908.433043-3-ryan.roberts@arm.com/
They would like this fixced in the jammy, and noble kernels.
For reference, here are the links to the above patches in 6.10-rc3:
* arm64: mm: Don't remap pgtables per-cont(pte|pmd) block
https://github.com/torvalds/linux/commit/5c63db59c5f89925add57642be4f789d0d671ccd
* arm64: mm: Batch dsb and isb when populating pgtables
https://github.com/torvalds/linux/commit/1fcb7cea8a5f7747e02230f816c2c80b060d9517
[Test Plan]

AWS has requested only the first two patches of the series of three patches be back ported.
[Test Plan]
I have tested this, as has AWS.
[Where problems could occur]
With the reordering of tlb invalidation and memory barriers, there is some risk, but this chance for regressions on this change is fairly small as the scope is fairly narrow.
