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:
v5.4.277 upstream stable release
from git://git.kernel.org/
Linux 5.4.277
docs: kernel_include.py: Cope with docutils 0.21
serial: kgdboc: Fix NMI-safety problems from keyboard reset code
usb: typec: ucsi: displayport: Fix potential deadlock
drm/amdgpu: Fix possible NULL dereference in amdgpu_ras_query_error_status_helper()
btrfs: add missing mutex_unlock in btrfs_relocate_sys_chunks()
arm64: dts: qcom: Fix 'interrupt-map' parent address cells
firmware: arm_scmi: Harden accesses to the reset domains
smb: client: fix potential OOBs in smb2_parse_contexts()
net: bcmgenet: synchronize UMAC_CMD access
net: bcmgenet: synchronize use of bcmgenet_set_rx_mode()
net: bcmgenet: synchronize EXT_RGMII_OOB_CTRL access
net: bcmgenet: keep MAC in reset until PHY is up
Revert "net: bcmgenet: use RGMII loopback for MAC reset"
Revert "selftests: mm: fix map_hugetlb failure on 64K page size systems"
ext4: fix bug_on in __es_tree_search
pinctrl: core: handle radix_tree_insert() errors in pinctrl_register_one_pin()
