There is a shift wrapping bug in this code on 32-bit architectures.
NETLBL_CATMAP_MAPTYPE is u64, bitmap is unsigned long.
Every second 32-bit word of catmap becomes corrupted.

From: David Christensen <drc@linux.vnet.ibm.com>
[ Upstream commit 7ebe4eda4265642859507d1b3ca330d8c196cfe5 ]
In the last step of the EEH recovery process, the EEH driver calls into
bnx2x_io_resume() to re-initialize the NIC hardware via the function
bnx2x_nic_load(). If an error occurs during bnx2x_nic_load(), OS and
hardware resources are released and an error code is returned to the
caller. When called from bnx2x_io_resume(), the return code is ignored
and the network interface is brought up unconditionally. Later attempts
to send a packet via this interface result in a page fault due to a null
pointer reference.
This patch checks the return code of bnx2x_nic_load(), prints an error
message if necessary, and does not enable the interface.

From: Enzo Matsumiya <ematsumiya@suse.de>
[ Upstream commit 50e63d6db6fd30a6dd9a33c49aa5b0bba36e1a92 ]
The virtio driver for Linux guests will not set a link speed to its
paravirtualized NICs. This will be seen as -1 in the ethernet layer, and
when some servers (e.g. samba) fetches it, it's converted to an unsigned
value (and multiplied by 1000 * 1000), so in client side we end up with:
1) Speed: 4294967295000000 bps
in DebugData.
This patch introduces a helper that returns a speed string (in Mbps or
Gbps) if interface speed is valid (>= SPEED_10 and <= SPEED_800000), or
"Unknown" otherwise.
The reason to not change the value in iface->speed is because we don't
know the real speed of the HW backing the server NIC, so let's keep
considering these as the fastest NICs available.
Also print "Capabilities: None" when the interface doesn't support any.

[ Upstream commit a0067dfcd9418fd3b0632bc59210d120d038a9c6 ]
The sctp_sf_eat_auth() function is supposed to return enum sctp_disposition
values but if the call to sctp_ulpevent_make_authkey() fails, it returns
-ENOMEM.
This results in calling BUG() inside the sctp_side_effects() function.
Calling BUG() is an over reaction and not helpful. Call WARN_ON_ONCE()
instead.
This code predates git.

Fix the I/O hang that arises because of the MSIx vector not having a mapped
online CPU upon receiving completion.
SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds
fetch the vector_no from mq_map after init is complete. Before init, they
have to use 0 - as per the norm.

command, so scsi_report_opcode() always fails, resulting in messages like
this:
hv_storvsc <guid>: tag#205 cmd 0xa3 status: scsi 0x2 srb 0x86 hv 0xc0000001
The recently added support for command duration limits calls
scsi_report_opcode() four times as each device comes online, which
significantly increases the number of messages logged in a system with many
disks.
Fix the problem by always marking Hyper-V synthetic SCSI devices as not
supporting scsi_report_opcode(). With this setting, the MAINTENANCE_IN SCSI
command is not issued and no messages are logged.

[ Upstream commit 9cefd6e7e0a77b0fbca5c793f6fb6821b0962775 ]
The kernel test robot reported sparse warnings regarding incorrect type
assignment for __be16 variables in bsg loopback path.
Change the flagged lines to use the be16_to_cpu() and cpu_to_be16() macros
appropriately.

[ Upstream commit 297224fc0922e7385573a30c29ffdabb67f27b7d ]
Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be
called concurrently from different code paths, we have no proper data
protection against races. Introduce open_mutex to each seq_oss_midi
object for avoiding the races.

There is a shift wrapping bug in this code on 32-bit architectures.
NETLBL_CATMAP_MAPTYPE is u64, bitmap is unsigned long.
Every second 32-bit word of catmap becomes corrupted.
