This reverts commit 61eee4a7fc40 ("ALSA: hda: Add support for Loongson 7A1000 controller").

[PATCH v4 0/7] Fix timeout clock used by hardware data timeout

by Sowjanya Komatineni

Tegra210/Tegra186/Tegra194 has incorrectly enabled SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK from the beginning of their support. Tegra210 and later SDMMC hardware default uses sdmmc_legacy_tm (TMCLK) all the time for hardware data timeout instead of SDCLK and this TMCLK need to be kept enabled by Tegra sdmmc driver. This series includes patches to fix this for Tegra210/Tegra186/Tegra194. These patches need to be manually backported for 4.9, 4.14 and 4.19. Will send patches to backport separately once these patches are ack'd. Delta between patch versions: [v4]: Include additional dt-binding patch [v3]: Same as v2 with fixes tag [v2]: Includes minor fix - Patch-0006: parentheses around operand of '!'

Kernel panic - not syncing: Attempted to kill init! x86_64 running 4.19

While running LTP tracing ftrace-stress-test kernel on x86_64 got panic on stable rc 4.19 branch. I have checked this kernel panic has been happening from the beginning of 4.19 release. I will run git bisect starting from 4.18 and get back to you on this email thread. steps to reproduce: # Boot qemu x86_64 with trace configs enabled. # cd /opt/ltp # ./runltp -f tracing Test output log: --------------------- ftrace-stress-test 1 TINFO: Start pid16=3123 /opt/ltp/testcases/bin/ftrace_stress/ftrace_tracing_cpumask.sh ftrace-stress-test 1 TINFO: Start pid17=3124 /opt/ltp/testcases/bin/ftrace_stress/ftrace_set_ftrace_filter.sh [ 81.695606] Core dump to |/bin/false pipe failed [ 81.696936] false (3169) used greatest stack depth: 11224 bytes left [ 81.711194] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b [ 81.711194] [ 81.720342] CPU: 2 PID: 1 Comm: systemd Not tainted 4.19.142-rc2 #1 [ 81.726622] Hardware name: Supermicro SYS-5019S-ML/X11SSH-F, BIOS 2.0b 07/27/2017 [ 81.734121] Call Trace: [ 81.736599] ? ftrace_graph_caller+0xb0/0xb0 [ 81.740890] dump_stack+0x7a/0xaa [ 81.744245] panic+0xe6/0x239 [ 81.747260] ? panic+0x5/0x239 [ 81.750343] ? ftrace_graph_caller+0xb0/0xb0 [ 81.754633] do_exit.cold+0xa0/0xb7 [ 81.758138] ? do_exit+0x5/0xb40 [ 81.761389] ? ftrace_return_to_handler+0x99/0xf0 [ 81.766115] ? ftrace_graph_caller+0xb0/0xb0 [ 81.770399] do_group_exit+0x47/0xb0 [ 81.773992] ? ftrace_graph_caller+0xb0/0xb0 [ 81.778277] get_signal+0x158/0x7e0 [ 81.781797] do_signal+0x37/0x640 [ 81.785136] ? trace_event_raw_event_rcu_dyntick+0x75/0xc0 [ 81.790658] exit_to_usermode_loop+0x78/0xd0 [ 81.794946] prepare_exit_to_usermode+0x66/0x90 [ 81.799495] ? page_fault+0x8/0x30 [ 81.802915] retint_user+0x8/0x18 [ 81.806259] RIP: 0033:0x7f62d3b648a8 [ 81.809850] Code: fe ff ff 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 00 00 55 66 0f ef c0 48 89 e5 41 56 41 54 53 48 81 ec 98 08 00 00 48 8b 45 28 <0f> 29 85 90 f7 ff ff 8b 1d 0f 68 38 00 0f 29 85 a0 f7 ff ff 4c 8b [ 81.828611] RSP: 002b:00007ffe44822e80 EFLAGS: 00010202 [ 81.833854] RAX: 00007ffe44823950 RBX: 00007ffe44823950 RCX: 00000000000000d7 [ 81.840997] RDX: 000055a3d336bc15 RSI: 0000000000000000 RDI: 0000000000000018 [ 81.848138] RBP: 00007ffe44823730 R08: 000055a3d336e9c5 R09: 0000000000000000 [ 81.855278] R10: 00007ffe44823788 R11: 0000000000000000 R12: 00007ffe44823800 [ 81.862419] R13: 00000000000000d7 R14: 00007ffe44823840 R15: 0000000000000018 [ 81.869625] Kernel Offset: 0x1f800000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff) [ 81.880417] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b [ 81.880417] ]--- [ 81.890803] ------------[ cut here ]------------ [ 81.895440] sched: Unexpected reschedule of offline CPU#3!

[PATCH 1/2] mm/migrate: Fixup setting UFFD_WP flag

by Alistair Popple

Commit f45ec5ff16a75 ("userfaultfd: wp: support swap and page migration") introduced support for tracking the uffd wp bit during page migration. However the non-swap PTE variant was used to set the flag for zone device private pages which are a type of swap page. This leads to corruption of the swap offset if the original PTE has the uffd_wp flag set.

[PATCH - stable v5.4 and v5.7] opp: Enable resources again if they were disabled earlier

by Viresh Kumar

From: Rajendra Nayak <rnayak(a)codeaurora.org> commit a4501bac0e553bed117b7e1b166d49731caf7260 upstream. dev_pm_opp_set_rate() can now be called with freq = 0 in order to either drop performance or bandwidth votes or to disable regulators on platforms which support them. In such cases, a subsequent call to dev_pm_opp_set_rate() with the same frequency ends up returning early because 'old_freq == freq' Instead make it fall through and put back the dropped performance and bandwidth votes and/or enable back the regulators.
