#1334075 — [PATCH 4.4 015/117] PCI: Fix minimum allocation address overwrite

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Biedl <linux-kernel.bfrz@manchmal.in-ulm.de>

commit 3460baa620685c20f5ee19afb6d99d26150c382c upstream.

Commit 36e097a8a297 ("PCI: Split out bridge window override of minimum
allocation address") claimed to do no functional changes but unfortunately
did: The "min" variable is altered.  At least the AVM A1 PCMCIA adapter was
no longer detected, breaking ISDN operation.

Use a local copy of "min" to restore the previous behaviour.

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: xuejiufei <xuejiufei@huawei.com>

commit c95a51807b730e4681e2ecbdfd669ca52601959e upstream.

When recovery master down, dlm_do_local_recovery_cleanup() only remove
the $RECOVERY lock owned by dead node, but do not clear the refmap bit.
Which will make umount thread falling in dead loop migrating $RECOVERY
to the dead node.

#1334077 — [PATCH 4.4 032/117] ALSA: compress: Disable GET_CODEC_CAPS ioctl for some architectures

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit 462b3f161beb62eeb290f4ec52f5ead29a2f8ac7 upstream.

Some architectures like PowerPC can handle the maximum struct size in
an ioctl only up to 13 bits, and struct snd_compr_codec_caps used by
SNDRV_COMPRESS_GET_CODEC_CAPS ioctl overflows this limit.  This
problem was revealed recently by a powerpc change, as it's now treated
as a fatal build error.

This patch is a stop-gap for that: for architectures with less than 14
bit ioctl struct size, get rid of the handling of the relevant ioctl.
We should provide an alternative equivalent ioctl code later, but for
now just paper over it.  Luckily, the compress API hasn't been used on
such architectures, so the impact must be effectively zero.

#1334079 — [PATCH 4.4 013/117] mtd: nand: assign reasonable default name for NAND drivers

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian Norris <computersforpeace@gmail.com>

commit f7a8e38f07a17be90758559fe66fe7337096053f upstream.

Commits such as commit 853f1c58c4b2 ("mtd: nand: omap2: show parent
device structure in sysfs") attempt to rely on the core MTD code to set
the MTD name based on the parent device. However, nand_base tries to set
a different default name according to the flash name (e.g., extracted
from the ONFI parameter page), which means NAND drivers will never make
use of the MTD defaults. This is not the intention of commit
853f1c58c4b2.

This results in problems when trying to use the cmdline partition
parser, since the MTD name is different than expected. Let's fix this by
providing a default NAND name, where possible.

Note that this is not really a great default name in the long run, since
this means that if there are multiple MTDs attached to the same
controller device, they will have the same name. But that is an existing
issue and requires future work on a better controller vs. flash chip
abstraction to fix properly.

Fixes: 853f1c58c4b2 ("mtd: nand: omap2: show parent device structure in sysfs")
