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:
v5.4.185 upstream stable release
from git://git.kernel.org/
clk: qcom: gdsc: Add support to update GDSC transition delay
arm64: dts: armada-3720-turris-mox: Add missing ethernet0 alias
virtio-blk: Don't use MAX_DISCARD_SEGMENTS if max_discard_seg is zero
net: qlogic: check the return value of dma_alloc_coherent() in
qed_vf_hw_prepare()
qed: return status of qed_iov_get_link
drm/sun4i: mixer: Fix P010 and P210 format numbers

gpio: ts4900: Do not set DAT and OE together
gianfar: ethtool: Fix refcount leak in gfar_get_ts_info
net: phy: DP83822: clear MISR2 register to disable interrupts
sctp: fix kernel-infoleak for SCTP sockets
net: bcmgenet: Don't claim WOL when its not available
net-sysfs: add check for netdevice being present to speed_show
Revert "xen-netback: remove 'hotplug-status' once it has served its purpose"
Revert "xen-netback: Check for hotplug-status existence before watching"
ipv6: prevent a possible race condition with lifetimes
tracing: Ensure trace buffer is at least 4096 bytes large
selftest/vm: fix map_fixed_noreplace test failure
selftests/memfd: clean up mapping in mfd_fail_write

net: macb: Fix lost RX packet wakeup race in NAPI receive
mmc: meson: Fix usage of meson_mmc_post_req()
riscv: Fix auipc+jalr relocation range checks
arm64: dts: marvell: armada-37xx: Remap IO space to bus address 0x0
virtio: unexport virtio_finalize_features
virtio: acknowledge all features before access
ARM: fix Thumb2 regression with Spectre BHB
ext4: add check to prevent attempting to resize an fs with sparse_super2
x86/cpufeatures: Mark two free bits in word 3
x86/cpu: Add hardware-enforced cache coherency as a CPUID feature
x86/mm/pat: Don't flush cache if hardware enforces cache coherency across
encryption domnains
KVM: SVM: Don't flush cache if hardware enforces cache coherency across
encryption domains
