2020-12-27proc mountinfo: make splice available againLinus Torvalds1-3/+6
Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

Commit 660c486590aa ("PCI: dwc: Set 32-bit DMA mask for MSI target address allocation") added dma_mask_set() call to explicitly set 32-bit DMA mask for MSI message mapping, but for now it throws a warning on ret == 0, while dma_set_mask() returns 0 in case of success. Fix this by inverting the condition.

Commit b9ac0f9dc8ea ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common code") broke enumeration of downstream devices on Tegra: In non-working case (next-20201211): 0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1) 0001:01:00.0 SATA controller: Marvell Technology Group Ltd.

Device 3380 (rev ab) 0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab) The problem seems to be dw_pcie_setup_rc() is now called twice before and after the link up handling. The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link. With this, the initialization ordering is restored to match the prior sequence.

2020-12-26drm/amd/display: avoid uninitialized variable warningLinus Torvalds1-1/+1
clang (quite rightly) complains fairly loudly about the newly added mpc1_get_mpc_out_mux() function returning an uninitialized value if the 'opp_id' checks don't pass. This may not happen in practice, but the code really shouldn't return garbage if the sanity checks don't pass. So just initialize 'val' to zero to avoid the issue.

2020-12-25genirq: Fix export of irq_to_desc() for powerpc KVMMichael Ellerman1-1/+1
Commit 64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()") removed the export of irq_to_desc() unless powerpc KVM is being built, because there is still a use of irq_to_desc() in modular code there. However it used: #ifdef CONFIG_KVM_BOOK3S_64_HV Which doesn't work when that symbol is =m, leading to a build failure: ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined! Fix it by checking for the definedness of the correct symbol which is CONFIG_KVM_BOOK3S_64_HV_MODULE.

Add socket as a separate member so that it doesn't have to be packed into the int value. When the socket ID was larger than 8 bits the output appeared corrupted or incomplete. For example, here on ThunderX2 'perf stat' reports a socket of -1 and an invalid die number: ./perf stat -a --per-die The socket id number is too big. Performance counter stats for 'system wide': S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized ... S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized ... And with --per-core there is an entry with an invalid core ID: ./perf stat record -a --per-core The socket id number is too big. Performance counter stats for 'system wide': S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized ... S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized ... This fixes the "Session topology" self test on ThunderX2. After this fix the output contains the correct socket and die IDs and no longer prints a warning about the size of the socket ID: ./perf stat --per-die -a Performance counter stats for 'system wide': S36-D0 128 169,869.39 msec cpu-clock # 127.501 CPUs utilized ...
