[PATCH v7 0/6] RISC-V Pointer Masking implementation


From: Alexey Baturo
Subject: [PATCH v7 0/6] RISC-V Pointer Masking implementation
Date: Sun, 10 Jan 2021 21:51:03 +0300

Hi folks,

Sorry it took me almost 3 month to provide the reply and fixes: it was a really 
busy EOY.
This series contains fixed @Alistair suggestion on enabling J-ext.

As for @Richard comments:
- Indeed I've missed appending review-by to the approved commits. Now I've 
restored them except for the fourth commit. @Richard could you please tell if 
you think it's still ok to commit it as is, or should I support masking mem ops 
for RVV first?
- These patches don't have any support for load/store masking for RVV and RVH 
extensions, so no support for special load/store for Hypervisor in particular.

If this patch series would be accepted, I think my further attention would be 
to:
- Support pm for memory operations for RVV
- Add proper csr and support pm for memory operations for Hypervisor mode
- Support address wrapping on unaligned accesses as @Richard mentioned 
previously

Thanks!
