[PATCH v3 00/10] enable write_misa() and RISCV_FEATURE_* cleanups

From: Daniel Henrique Barboza
Subject: [PATCH v3 00/10] enable write_misa() and RISCV_FEATURE_* cleanups
Date: Wed, 15 Feb 2023 15:57:16 -0300


In this new version the most notable change was in the write_misa()
logic. I decided to follow Bin's suggestion and removed the verification
at the start of the function.

As the result, the patch that removes RISCV_FEATURE_MISA was merged with
the patch that makes this change (patch 2).

I also removed the v2 acks from it since the patch now does something
different than before. Patch 2 is also the only patch that is missing

Changes from v2:
- all patches but patch 2 are acked/reviewed
- patch 2:
  - remove the RISCV_FEATURE_MISA validation from write_misa()
- v2 link: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg03934.html

  target/riscv: do not mask unsupported QEMU extensions in write_misa()
  target/riscv: always allow write_misa() to write MISA
