2020-10-05regmap: irq: Add support to clear ack registersLaxminath Kasam
For particular codec HWs have requirement to toggle interrupt clear register twice 0->1->0. To accommodate it, need to add one more field (clear_ack) in the regmap_irq struct and update regmap-irq driver to support it.

2020-10-01xen/events: don't use chip_data for legacy IRQsJuergen Gross
Since commit c330fb1ddc0a ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.") Xen is using the chip_data pointer for storing IRQ specific data. When running as a HVM domain this can result in problems for legacy IRQs, as those might use chip_data for their own purposes. Use a local array for this purpose in case of legacy IRQs, avoiding the double use.

2020-10-01iommu/amd: Fix the overwritten field in IVMD headerAdrian Huang
Commit 387caf0b759a ("iommu/amd: Treat per-device exclusion ranges as r/w unity-mapped regions") accidentally overwrites the 'flags' field in IVMD (struct ivmd_header) when the I/O virtualization memory definition is associated with the exclusion range entry. This leads to the corrupted IVMD table (incorrect checksum). The kdump kernel reports the invalid checksum: ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177) AMD-Vi: [Firmware Bug]: IVRS invalid checksum Fix the above-mentioned issue by modifying the 'struct unity_map_entry' member instead of the IVMD header.

2020-10-01gpio: pca953x: Correctly initialize registers 6 and 7 for PCA957xAndy Shevchenko
When driver has been converted to the bitmap API the non-bitmap functions started behaving differently on 32-bit BE architectures since the bytes in two consequent unsigned longs are in different order in comparison to byte array. Hence if the chip had had more than 32 lines the memset() call over it would have not set up upper lines correctly. Although it's currently a theoretical case (no supported chips of this type has 32+ lines), it's better to provide a clean code to avoid people thinking this is okay and potentially producing not fully working things.

2020-09-29scsi: iscsi: iscsi_tcp: Avoid holding spinlock while calling getpeername()Mark Mielke
The kernel may fail to boot or devices may fail to come up when initializing iscsi_tcp devices starting with Linux 5.8. Commit a79af8a64d39 ("[SCSI] iscsi_tcp: use iscsi_conn_get_addr_param libiscsi function") introduced getpeername() within the session spinlock. Commit 1b66d253610c ("bpf: Add get{peer, sock}name attach types for sock_addr") introduced BPF_CGROUP_RUN_SA_PROG_LOCK() within getpeername(), which acquires a mutex and when used from iscsi_tcp devices can now lead to "BUG: scheduling while atomic:" and subsequent damage. Ensure that the spinlock is released before calling getpeername() or getsockname(). sock_hold() and sock_put() are used to ensure that the socket reference is preserved until after the getpeername() or getsockname() complete.

2020-09-29drm/amdgpu: restore proper ref count in amdgpu_display_crtc_set_configJean Delvare
A recent attempt to fix a ref count leak in amdgpu_display_crtc_set_config() turned out to be doing too much and "fixed" an intended decrease as if it were a leak. Undo that part to restore the proper balance. This is the very nature of this function to increase or decrease the power reference count depending on the situation. Consequences of this bug is that the power reference would eventually get down to 0 while the display was still in use, resulting in that display switching off unexpectedly.

2020-09-28Merge series "use semicolons rather than commas to separate statements" from ↵Mark Brown
Julia Lawall <Julia.Lawall@inria.fr>: These patches replace commas by semicolons. This was done using the Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below. This semantic patch ensures that commas inside for loop headers will not be transformed. It also doesn't touch macro definitions. Coccinelle ensures that braces are added as needed when a single-statement branch turns into a multi-statement one. This semantic patch has a few false positives, for variable delcarations such as: LIST_HEAD(x), *y; The semantic patch could be improved to avoid these, but for the moment they have been removed manually (2 occurrences). // <smpl> @initialize:ocaml@ @@ let infunction p = (* avoid macros *) (List.hd p).current_element <> "something_else" let combined p1 p2 = (List.hd p1).line_end = (List.hd p2).line || (((List.hd p1).line_end < (List.hd p2).line) && ((List.hd p1).col < (List.hd p2).col)) @bad@ statement S; declaration d; position p; @@ S@p d // special cases where newlines are needed (hope for no more than 5) @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @r@ expression e1,e2; statement S; position p != bad.p; @@ e1 ,@S@p e2; @@ expression e1,e2; position p1; position p2 : script:ocaml(p1) { infunction p1 && not(combined p1 p2) }; statement S; position r.p; @@ e1@p1 -,@S@p +; e2@p2 ... when any // </smpl> --- drivers/acpi/processor_idle.c | 4 +++- drivers/ata/pata_icside.c | 21 +++++++++++++-------- drivers/base/regmap/regmap-debugfs.c | 2 +- drivers/bcma/driver_pci_host.c | 4 ++-- drivers/block/drbd/drbd_receiver.c | 6 ++++-- drivers/char/agp/amd-k7-agp.c | 2 +- drivers/char/agp/nvidia-agp.c | 2 +- drivers/char/agp/sworks-agp.c | 2 +- drivers/char/hw_random/iproc-rng200.c | 8 ++++---- drivers/char/hw_random/mxc-rnga.c | 6 +++--- drivers/char/hw_random/stm32-rng.c | 8 ++++---- drivers/char/ipmi/bt-bmc.c | 6 +++--- drivers/clk/meson/meson-aoclk.c | 2 +- drivers/clk/mvebu/ap-cpu-clk.c | 2 +- drivers/clk/uniphier/clk-uniphier-cpugear.c | 2 +- drivers/clk/uniphier/clk-uniphier-mux.c | 2 +- drivers/clocksource/mps2-timer.c | 6 +++--- drivers/clocksource/timer-armada-370-xp.c | 8 ++++---- drivers/counter/ti-eqep.c | 2 +- drivers/crypto/amcc/crypto4xx_alg.c | 2 +- drivers/crypto/atmel-tdes.c | 2 +- drivers/crypto/hifn_795x.c | 4 ++-- drivers/crypto/talitos.c | 8 ++++---- 23 files changed, 60 insertions(+), 51 deletions(-)
