Subject: [kvm-unit-tests 0/7] More tests for selective CR0 intercept

From: Yosry Ahmed <yosryahmed@...gle.com>

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 1-5 are cleanups and prep work. Patch 6 generalizes the existing
test to make it easy to extend, and patch 7 adds the actual tests.

Yosry Ahmed (7):
  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
