Subject: [kvm-unit-tests v2 0/8] More tests for selective CR0 intercept

Add more test cases for the selective CR0 write intercept, covering bugs
fixed by
https://lore.kernel.org/kvm/20251024192918.3191141-1-yosry.ahmed@linux.dev/.

Patches 1-6 are cleanups and prep work. Patch 7 generalizes the existing
test to make it easy to extend, and patch 8 adds the actual tests.

v1 -> v2:
- Fixed author and Signed-off-by.
- Added fix for skip return codes.

Yosry Ahmed (8):
  scripts: Always return '2' when skipping tests
  x86/svm: Cleanup selective cr0 write intercept test
  x86/svm: Move CR0 selective write intercept test near CR3 intercept
  x86/svm: Add FEP helpers for SVM tests
  x86/svm: Report unsupported SVM tests
  x86/svm: Move report_svm_guest() to the top of svm_tests.c
  x86/svm: Generalize and improve selective CR0 write intercept test
  x86/svm: Add more selective CR0 write and LMSW test cases
