Request for reviews for 4.4-st39, 4.4-cip74, 4.4-cip74-rt43

[Ulrich Hecht <uli@fpond.eu>]

Hi!

Here are the manual backports for the upcoming 4.4-st39, 4.4-cip74 and 4.4-cip74-rt43 releases that should be reviewed, and that can currently be found in https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git/log/?h=linux-4.4.y-st-rc

Trivial backports:

** m | d2d3052d9 6f8ecb o+ | gpio: vf610: connect GPIO label to dev name
** m | c075aa346 5d5aa2 o  | ARM: dts: exynos: Use Exynos5420 compatible for the MIPI video phy
** m | 09fa241bc 4971c2 o+ | ima: Align ima_file_mmap() parameters with mmap_file LSM hook
** m | 38345d84e aa56b9 o  | dm flakey: fix logic when corrupting a bio
** m | c214be981 709fca o  | Bluetooth: hci_sock: purge socket queues in the destruct() callback
** m | 9acadaf26 a98fc2    | staging: rtl8192e: Remove function ..dm_check_ac_dc_power calling a script
** m | 1c4293ded fe413a    | staging: rtl8192e: Remove call_usermodehelper starting RadioPower.sh
** m | 85f922f42 c22c3b o+ | net: phy: smsc: bail out in lan87xx_read_status if genphy_read_status fails

Not completely trivial backports, and/or stuff that touches important subsystems:

** m | 4e3b4b170 9a5571 o+ | f2fs: fix information leak in f2fs_move_inline_dirents()
** m | 5621f7a81 256fe4 o  | udf: Do not update file length for failed writes to inline files
** m | 11790a4fa b06730 o+ | irqdomain: Fix association race
** m | 30b560087 3f883c o+ | irqdomain: Fix disassociation race
** m | b40d2fbf4 4d57a7 o+ | ubi: ubi_wl_put_peb: Fix infinite loop when wear-leveling work failed
** m | 3df6f492f db4df8 o  | tty: fix out-of-bounds access in tty_driver_lookup_tty()
** m | 438d62a68 c4c81d o  | tty: serial: fsl_lpuart: disable the CTS when send break signal

I would also like an opinion or two on the importance of this patch:

** i | d5cf15857 e88b2c o+ | bpf: Fix 32 bit src register truncation on div/mod

I have chosen not to include it because it would require backporting quite a bit of infrastructure. According to the bug report at https://bugzilla.redhat.com/show_bug.cgi?id=1981954, the issue is not exploitable for out-of-bounds accesses on 4.4.

Thanks!
