Subject: [ANNOUNCE] x86-cpuid-db: Release v2.1

Hi,

I'm happy to announce release 2.1 of the x86-cpuid-db project:

  https://gitlab.com/x86-cpuid.org/x86-cpuid-db
  https://gitlab.com/x86-cpuid.org/x86-cpuid-db/-/releases/v2.1

Changelog v2.1
--------------

- Add spellchecking and x86 terminology style enforcement for all CPUID
  bitfield descriptions in the XML database.  Build multiple x86
  specific hunspell(5) dictionary and affix files for such enforcement.

- Use such logic to standardize the style for x86 trademarks, registers,
  opcodes, byte units, hexadecimal digits, and x86 abbreviated and
  non-abbreviated technical terms.

- Similarly, refuse abbreviated terms that might be OK in code but not
  in official listings (e.g., "addr", "instr", "reg", "virt", etc.)

- Introduce scripts/spellcheck_xml.sh to automate the hunspell
  invocation, and add it to the project's CI pipeline.

- Update the CPUID database:

  - Leaf 0xd: Apply vendor fixes from Andrew Cooper (Xen / Citrix)

  - Leaf 0x80000020/0x80000021: Add new Zen5 SoC bits.  Thanks to
    Avadhut Naik (AMD).

  - Leaf 0x7: Add new NMI source reporting bit.  Thanks to Sohil
    Mehta (Intel).

  - All leaves: Fix all issues identified by the new hunspell(5)
    pipeline.

Release coverage
----------------

  CPUID leaves:        63 leaves
