[PATCH v7 00/20] target/riscv, KVM: fixes and enhancements

[Daniel Henrique Barboza]

Hi,

This version includes most of the fixes and changes suggested in the v6
review [1].

Unfortunately we weren't able to proceed with Drew's suggestion to avoid
assigning 'name' and 'description' during runtime in patch 11 because
some Gitlab runners (clang-user and tsan-build) complained about
misa_ext_info_arr[] not being a compiler-time constant. I documented
this 'clang' situation in patch 11 commit msg.

The change to use __builtin_ctz() instead of ctz32() was kept because
it's clearer to use the MISA bits (RVA, RVC ...) as input for
MISA_EXT_INFO() than doing a calculation with (letter - 'A').

All other suggestions from both Drew and Phil were implemented. 'sudo'
references from commit msgs were removed from patches 1 and 2 as
suggested by Michael (R-bs were kept).

Series based on top of Alistair's riscv-to-apply.next.

Patches missing review: 11, 12

Changes from v6:
- patches 1 and 2: removed 'sudo' references from commit msgs
- patch 11:
  - use __builtin_ctz() instead of ctz32() in MISA_EXT_INFO
  - renamed getter to riscv_get_misa_ext_description()
  - do input/output validation in both getters
- patch 12:
  - use object_property_find() to skip the property if it already exists
