This series contains the fix for __kvmhv_copy_tofrom_guest_radix plus a couple of changes. - Patch 1: The fix itself. I thought a smaller fix upfront would be better to facilitate any backports. - Patch 2: Adds a sanity check to the low level function. Since the hcall API already enforces that the effective address must be on quadrant 0, moving the checks from the high level function would only add overhead to the hcall path, so I opted for a lightweight check at the low level. - Patch 3: Cleans up the EXPORT_SYMBOL_GPL tags. I don't see how they would be needed since the functions are contained within kvm-hv.ko. v1: https://lkml.kernel.org/r/20210802234941.2568493-1-farosas@linux.ibm.com Fabiano Rosas (3): KVM: PPC: Book3S HV: Fix copy_tofrom_guest routines KVM: PPC: Book3S HV: Add sanity check to copy_tofrom_guest KVM: PPC: Book3S HV: Stop exporting symbols from book3s_64_mmu_radix arch/powerpc/kvm/book3s_64_mmu_radix.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-)
