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:
v5.15.60 upstream stable release
from git://git.kernel.org/
x86/speculation: Make all RETbleed mitigations 64-bit only
selftests/bpf: Extend verifier and bpf_sock tests for dst_port loads
selftests/bpf: Check dst_port only on the client socket
block: fix default IO priority handling again
tools/vm/slabinfo: Handle files in debugfs
ACPI: video: Force backlight native for some TongFang devices
ACPI: video: Shortening quirk list by identifying Clevo by board_name only
ACPI: APEI: Better fix to avoid spamming the console with old error logs
crypto: arm64/poly1305 - fix a read out-of-bound
KVM: x86: do not report a vCPU as preempted outside instruction boundaries
KVM: x86: do not set st->preempted when going back to user space
KVM: selftests: Make hyperv_clock selftest more stable
tools/kvm_stat: fix display of error when multiple processes are found
selftests: KVM: Handle compiler optimizations in ucall
KVM: x86/svm: add __GFP_ACCOUNT to __sev_dbg_{en,de}crypt_user()
