Hi Anup, while you did fix the bug that caused the mailing list date to disappear, I noticed that these patches have been _applied_ (not just rebased) earlier today, just a few hours before sending the pull request. The pull request was sent around midnight, Indian time, while the patches were applied around 5-6pm. I recognized that this is not a rebase because the commit dates are grouped according to the topicsL 17:38:40 +0530 KVM: RISC-V: Retry fault if vma_lookup() results become invalid 17:38:42 +0530 RISC-V: KVM: Alphabetize selects 17:38:44 +0530 RISC-V: KVM: Add ONE_REG interface to enable/disable SBI extensions 17:38:46 +0530 RISC-V: KVM: Allow Zbb extension for Guest/VM 17:45:39 +0530 RISC-V: Add AIA related CSR defines 17:45:42 +0530 RISC-V: Detect AIA CSRs from ISA string 17:45:44 +0530 RISC-V: KVM: Drop the _MASK suffix from hgatp.VMID mask defines 17:45:48 +0530 RISC-V: KVM: Initial skeletal support for AIA 17:45:51 +0530 RISC-V: KVM: Implement subtype for CSR ONE_REG interface 17:45:54 +0530 RISC-V: KVM: Add ONE_REG interface for AIA CSRs 17:45:58 +0530 RISC-V: KVM: Use bitmap for irqs_pending and irqs_pending_mask 18:10:27 2023 +0530 RISC-V: KVM: Virtualize per-HART AIA CSRs What this means, is that there is no way that these patches have been tested by anyone except you. Please try to push to the kvm-riscv/next branch as soon as patches are ready, since that makes it easier to spot conflicts between architectures. In fact, since RISC-V is still pretty small, feel free to send me pull requests even early in the development period, as soon as some patches are ready.
