drm/i915/perf: Use GTT when saving/restoring engine GPR

2020-07-22T07:34:29Z

commit aee62e02c48bd62b9b07f5e297ecfc9aaa964937 upstream. MI_STORE_REGISTER_MEM and MI_LOAD_REGISTER_MEM need to know which translation to use when saving restoring the engine general purpose registers to and from the GT scratch. Since GT scratch is mapped to ggtt, we need to set an additional bit in the command to use GTT.

bpf: sockmap: Require attach_bpf_fd when detaching a program

2020-07-22T07:34:29Z

commit bb0de3131f4c60a9bf976681e0fe4d1e55c7a821 upstream. The sockmap code currently ignores the value of attach_bpf_fd when detaching a program. This is contrary to the usual behaviour of checking that attach_bpf_fd represents the currently attached program. Ensure that attach_bpf_fd is indeed the currently attached program. It turns out that all sockmap selftests already do this, which indicates that this is unlikely to cause breakage.

commit 9b2b09717e1812e450782a43ca0c2790651cf380 upstream. Using BPF_PROG_ATTACH on a sockmap program currently understands no flags or replace_bpf_fd, but accepts any value. Return EINVAL instead.

gpio: pca953x: disable regmap locking for automatic address incrementing

2020-07-22T07:34:29Z

commit ec3decd21380081e3b5de4ba8d85d90a95f201a0 upstream. It's a repetition of the commit aa58a21ae378 ("gpio: pca953x: disable regmap locking") which states the following: This driver uses its own locking but regmap silently uses a mutex for all operations too. Add the option to disable locking to the regmap config struct.

mm/memory.c: properly pte_offset_map_lock/unlock in vm_insert_pages()

2020-07-22T07:34:28Z

commit 7f70c2a68a51496289df163f6969d4db7c383f30 upstream. Calls to pte_offset_map() in vm_insert_pages() are erroneously not matched with a call to pte_unmap(). This would cause problems on architectures where that is not a no-op. This patch does away with the non-traditional locking in the existing code, and instead uses pte_offset_map_lock/unlock() as usual, incrementing PTE as necessary. The PTE pointer is kept within bounds since we clamp it with PTRS_PER_PTE.

iommu/vt-d: Make Intel SVM code 64-bit only

2020-07-22T07:34:28Z

commit 9486727f5981a5ec5c0b699fb1777451bd6786e4 upstream. Current Intel SVM is designed by setting the pgd_t of the processor page table to FLPTR field of the PASID entry. The first level translation only supports 4 and 5 level paging structures, hence it's infeasible for the IOMMU to share a processor's page table when it's running in 32-bit mode. Let's disable 32bit support for now and claim support only when all the missing pieces are ready in the future.
