2022-07-25sctp: fix sleep in atomic context bug in timer handlersDuoming Zhou
There are sleep in atomic context bugs in timer handlers of sctp such as sctp_generate_t3_rtx_event(), sctp_generate_probe_event(), sctp_generate_t1_init_event(), sctp_generate_timeout_event(), sctp_generate_t3_rtx_event() and so on. The root cause is sctp_sched_prio_init_sid() with GFP_KERNEL parameter that may sleep could be called by different timer handlers which is in interrupt context. One of the call paths that could trigger bug is shown below: (interrupt context) sctp_generate_probe_event sctp_do_sm sctp_side_effects sctp_cmd_interpreter sctp_outq_teardown sctp_outq_init sctp_sched_set_sched n->init_sid(..,GFP_KERNEL) sctp_sched_prio_init_sid //may sleep This patch changes gfp_t parameter of init_sid in sctp_sched_set_sched() from GFP_KERNEL to GFP_ATOMIC in order to prevent sleep in atomic context bugs.

2022-07-25net: ethernet: stmicro: stmmac: permit MTU change with interface upChristian Marangi
Remove the limitation where the interface needs to be down to change MTU by releasing and opening the stmmac driver to set the new MTU. Also call the set_filter function to correctly init the port. This permits to remove the EBUSY error while the ethernet port is running permitting a correct MTU change if for example a DSA request a MTU change for a switch CPU port.

2022-07-25net: dsa: fix reference counting for LAG FDBsVladimir Oltean
Due to an invalid conflict resolution on my side while working on 2 different series (LAG FDBs and FDB isolation), dsa_switch_do_lag_fdb_add() does not store the database associated with a dsa_mac_addr structure. So after adding an FDB entry associated with a LAG, dsa_mac_addr_find() fails to find it while deleting it, because &a->db is zeroized memory for all stored FDB entries of lag->fdbs, and dsa_switch_do_lag_fdb_del() returns -ENOENT rather than deleting the entry.

2022-07-26drm/amdgpu: Re-enable DCN for 64-bit powerpcMichael Ellerman
Commit d11219ad53dc ("amdgpu: disable powerpc support for the newer display engine") disabled the DCN driver for all of powerpc due to unresolved build failures with some compilers. Further digging shows that the build failures only occur with compilers that default to 64-bit long double. Both the ppc64 and ppc64le ABIs define long double to be 128-bits, but there are compilers in the wild that default to 64-bits. The compilers provided by the major distros (Fedora, Ubuntu) default to 128-bits and are not affected by the build failure. There is a compiler flag to force 128-bit long double, which may be the correct long term fix, but as an interim fix only allow building the DCN driver if long double is 128-bits by default. The bisection in commit d11219ad53dc must have gone off the rails at some point, the build failure occurs all the way back to the original commit that enabled DCN support on powerpc, at least with some toolchains.

2022-07-25drm/amd/display: Copy crc_skip_count when duplicating CRTC stateLeo Li
[Why] crc_skip_count is used to track how many frames to skip to allow the OTG CRC engine to "warm up" before it outputs correct CRC values. Experimentally, this seems to be 2 frames. When duplicating CRTC states, this value was not copied to the duplicated state. Therefore, when this state is committed, we will needlessly wait 2 frames before outputing CRC values. Even if the CRC engine is already warmed up. [How] Copy the crc_skip_count as part of dm_crtc_duplicate_state.

2022-07-25drm/amd/display: Fix OPTC function pointers for DCN314Nicholas Kazlauskas
[Why] Access violation occurs when swapping between HDMI and FRL monitors because we're missing the immediate_disable_crtc callback and it's required for the DCN314 clk manager. [How] Update the table to match the DCN31 optc functions for ones that should be the same: - immediate_disable_crtc - configure_crc Reviewed-by: Michael Strauss <Michael.Strauss@amd.com> Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2022-07-25drm/amd/display: Add enable/disable FIFO callbacks to stream setupNicholas Kazlauskas
[Why] We don't write out attributes after disabling and re-enabling the link on some monitors, causing some, but not all, HDMI displays to fail to lightup on DCN314. [How] Firmware used to do this after DIG link setup. Since firmware is no longer doing this to support USB4 and dynamic link remapping we'll need to add this to driver in the equivalent paths. New optional callbacks were created in the stream encoder interface and implementations were added for DCN314.

[why] In some cases MPC tree bottom pipe ends up point to itself. This causes iterating from top to bottom to hang the system in an infinite loop. [how] When looping to next MPC bottom pipe, check that the pointer is not same as current to avoid infinite loop.

2022-07-25intel_idle: make SPR C1 and C1E be independentArtem Bityutskiy
This patch partially reverts the changes made by the following commit: da0e58c038e6 intel_idle: add 'preferred_cstates' module argument As that commit describes, on early Sapphire Rapids Xeon platforms the C1 and C1E states were mutually exclusive, so that users could only have either C1 and C6, or C1E and C6. However, Intel firmware engineers managed to remove this limitation and make C1 and C1E to be completely independent, just like on previous Xeon platforms. Therefore, this patch: * Removes commentary describing the old, and now non-existing SPR C1E limitation. * Marks SPR C1E as available by default. * Removes the 'preferred_cstates' parameter handling for SPR. Both C1 and C1E will be available regardless of 'preferred_cstates' value. We expect that all SPR systems are shipping with new firmware, which includes the C1/C1E improvement.

2022-07-25cpufreq: ondemand: Use cpumask_var_t for on-stack cpu maskZhao Liu
A cpumask structure on the stack can cause a warning with CONFIG_NR_CPUS=8192 (e.g. Ubuntu 22.04 uses this): drivers/cpufreq/cpufreq_ondemand.c: In function 'od_set_powersave_bias': drivers/cpufreq/cpufreq_ondemand.c:449:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] 449 | } | ^ CONFIG_CPUMASK_OFFSTACK=y is enabled by default for most distros, and hence we can work around the warning by using cpumask_var_t.

2022-07-25btrfs: don't call btrfs_page_set_checked in finish_compressed_bio_readChristoph Hellwig
This flag was used to communicate that the low-level compression code already did verify the checksum to the high-level I/O completion code. But it has been unused for a long time as the upper btrfs_bio for the decompressed data had a NULL csum pointer basically since that pointer existed and the code already checks for that a little later. Note that this does not affect the other use of the checked flag, which is only used for the COW fixup worker.
