Focal update: v5.4.277 upstream stable release

[Manuel Diewald]

    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:

       v5.4.277 upstream stable release
       from git://git.kernel.org/

pinctrl: core: handle radix_tree_insert() errors in pinctrl_register_one_pin()
ext4: fix bug_on in __es_tree_search
Revert "selftests: mm: fix map_hugetlb failure on 64K page size systems"
Revert "net: bcmgenet: use RGMII loopback for MAC reset"
net: bcmgenet: keep MAC in reset until PHY is up
net: bcmgenet: synchronize EXT_RGMII_OOB_CTRL access
net: bcmgenet: synchronize use of bcmgenet_set_rx_mode()
net: bcmgenet: synchronize UMAC_CMD access
smb: client: fix potential OOBs in smb2_parse_contexts()

Linux 5.4.277
UBUNTU: Upstream stable to v5.4.277

[Matt Arnold (mattarnold700)]

Hi Manuel,

Thank you for the detailed update and the work you've put into integrating the v5.4.277 upstream stable release. It's great to see these essential patches being addressed, especially those targeting critical areas like ext4, networking, and arm64.

However, I noticed the status change from "Confirmed" to "Invalid" for the Linux (Ubuntu) package. Could you provide some clarification on why this change was made? It would help to understand if there were any specific issues or conflicts that led to this decision.

Hi Matt,
This upstream stable update is series-specific (focal), so I set the status of the generic linux package to 'Invalid'. Its status is tracked only for focal, and as you can see it is currently 'In Progress'. Once it is applied to the tree, the status will be changed to 'Fix committed' and eventually to 'Fix Released' once a kernel package carrying the changes has been released.
