Hi,

I've rebased this patch series and addressed Richard's and Daniel's comments.
Thanks

*** BLURB HERE ***
[v0]:
As Pointer Masking is finally ratified, these patches intend to update the existing code to the final version.
These patches have been submitted previously and I tried to address all the suggestions, but I'd suggest to review them from the clean slate and then finally push them to the repo.
Thanks.

Alexey Baturo (7):
  target/riscv: Remove obsolete pointer masking extension code.
  target/riscv: Add new CSR fields for S{sn,mn,m}pm extensions as part
    of Zjpm v1.0
  target/riscv: Add helper functions to calculate current number of
    masked bits for pointer masking
  target/riscv: Add pointer masking tb flags
  target/riscv: Update address modify functions to take into account
    pointer masking
  target/riscv: Apply pointer masking for virtualized memory accesses
  target/riscv: Enable updates for pointer masking variables and thus
    enable pointer masking extension
