#1707946 — [PATCH 3.18 33/92] [media] v4l: s5c73m3: fix negation operator

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

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

From: Andrzej Hajda <a.hajda@samsung.com>

commit a2370ba2752538404e363346b339869c9973aeac upstream.

Bool values should be negated using logical operators. Using bitwise operators
results in unexpected and possibly incorrect results.

#1707949 — [PATCH 3.18 74/92] rtnetlink: allocate more memory for dev_set_mac_address()

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

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

From: WANG Cong <xiyou.wangcong@gmail.com>


[ Upstream commit 153711f9421be5dbc973dc57a4109dc9d54c89b1 ]

virtnet_set_mac_address() interprets mac address as struct
sockaddr, but upper layer only allocates dev->addr_len
which is ETH_ALEN + sizeof(sa_family_t) in this case.

We lack a unified definition for mac address, so just fix
the upper layer, this also allows drivers to interpret it
to struct sockaddr freely.

#1707951 — [PATCH 3.18 04/92] powerpc/pseries: Fix of_node_put() underflow during reconfig remove

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

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

From: Laurent Vivier <lvivier@redhat.com>

commit 4fd1bd443e80b12f0a01a45fb9a793206b41cb72 upstream.

As for commit 68baf692c435 ("powerpc/pseries: Fix of_node_put()
underflow during DLPAR remove"), the call to of_node_put() must be
removed from pSeries_reconfig_remove_node().

dlpar_detach_node() and pSeries_reconfig_remove_node() both call
of_detach_node(), and thus the node should not be released in both
cases.

#1707953 — [PATCH 3.18 09/92] KVM: PPC: Book3S HV: Save/restore host values of debug registers

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

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

From: Paul Mackerras <paulus@ozlabs.org>

commit 7ceaa6dcd8c6f59588428cec37f3c8093dd1011f upstream.

At present, HV KVM on POWER8 and POWER9 machines loses any instruction
or data breakpoint set in the host whenever a guest is run.
Instruction breakpoints are currently only used by xmon, but ptrace
and the perf_event subsystem can set data breakpoints as well as xmon.

To fix this, we save the host values of the debug registers (CIABR,
DAWR and DAWRX) before entering the guest and restore them on exit.
To provide space to save them in the stack frame, we expand the stack
frame allocated by kvmppc_hv_entry() from 112 to 144 bytes.

[paulus@ozlabs.org - Adjusted stack offsets since we aren't saving
 POWER9-specific registers.]

#1707954 — [PATCH 3.18 05/92] md/raid5: add thread_group worker async_tx_issue_pending_all

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

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

From: Ofer Heifetz <oferh@marvell.com>

commit 7e96d559634b73a8158ee99a7abece2eacec2668 upstream.

Since thread_group worker and raid5d kthread are not in sync, if
worker writes stripe before raid5d then requests will be waiting
for issue_pendig.

Issue observed when building raid5 with ext4, in some build runs
jbd2 would get hung and requests were waiting in the HW engine
waiting to be issued.

Fix this by adding a call to async_tx_issue_pending_all in the
raid5_do_work.

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

From: Yuejie Shi <syjcnss@gmail.com>

commit 89e357d83c06b6fac581c3ca7f0ee3ae7e67109e upstream.

A dump may come in the middle of another dump, modifying its dump
structure members. This race condition will result in NULL pointer
dereference in kernel. So add a lock to prevent that race.
