Public bug reported: SRU Justification
Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch. The following upstream stable patches should be included in the Ubuntu kernel: upstream stable patchset 2019-10-31 Ported from the following upstream stable releases: v4.19.79, v5.3.6 from git://git.kernel.org/ s390/process: avoid potential reading of freed stack KVM: s390: Test for bad access register and size at the start of S390_MEM_OP s390/topology: avoid firing events before kobjs are created s390/cio: exclude subchannels with no parent from pseudo check KVM: PPC: Book3S HV: Fix race in re-enabling XIVE escalation interrupts KVM: PPC: Book3S HV: Check for MMU ready on piggybacked virtual cores KVM: PPC: Book3S HV: Don't lose pending doorbell request on migration on P9 KVM: X86: Fix userspace set invalid CR4 nbd: fix max number of supported devs PM / devfreq: tegra: Fix kHz to Hz conversion ASoC: Define a set of DAPM pre/post-up events ASoC: sgtl5000: Improve VAG power and mute control powerpc/mce: Fix MCE handling for huge pages powerpc/mce: Schedule work from irq_work powerpc/powernv: Restrict OPAL symbol map to only be readable by root powerpc/powernv/ioda: Fix race in TCE level allocation powerpc/book3s64/mm: Don't do tlbie fixup for some hardware revisions can: mcp251x: mcp251x_hw_reset(): allow more time after a reset tools lib traceevent: Fix "robust" test of do_generate_dynamic_list_file crypto: qat -
