I was anticipating landing James' lockless page aging series, but I didn't get to the review until too late in the cycle (it's looking good for 6.15 though). The following changes since commit 3522c419758ee8dca5a0e8753ee0070a22157bc1: Merge tag 'kvm-riscv-fixes-6.13-1' of https://github.com/kvm-riscv/linux into HEAD (2024-12-13 13:59:20 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-mmu-6.14 for you to fetch changes up to 2d5faa6a8402435d6332e8e8f3c3f18cca382d83: KVM/x86: add comment to kvm_mmu_do_page_fault() (2024-12-16 15:27:34 -0800) ---------------------------------------------------------------- KVM x86 MMU changes for 6.14: - Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a direct call to kvm_tdp_page_fault() when RETPOLINE is enabled. ---------------------------------------------------------------- Juergen Gross (1): KVM/x86: add comment to kvm_mmu_do_page_fault() arch/x86/kvm/mmu/mmu_internal.h | 4 ++++ 1 file changed, 4 insertions(+)
