On SYSTEMPORT Lite, since we have the main interrupt source in the first
cell, the second cell is the Wake-on-LAN interrupt, yet the code was not
properly updated to fetch the second cell, and instead looked at the
third and non-existing cell for Wake-on-LAN.

The BAD_MADT_GICC_ENTRY() macro checks if a GICC MADT entry passes
muster from an ACPI specification standpoint. Current macro detects the
MADT GICC entry length through ACPI firmware version (it changed from 76
to 80 bytes in the transition from ACPI 5.1 to ACPI 6.0 specification)
but always uses (erroneously) the ACPICA (latest) struct (ie struct
acpi_madt_generic_interrupt - that is 80-bytes long) length to check if
the current GICC entry memory record exceeds the MADT table end in
memory as defined by the MADT table header itself, which may result in
false negatives depending on the ACPI firmware version and how the MADT
entries are laid out in memory (ie on ACPI 5.1 firmware MADT GICC
entries are 76 bytes long, so by adding 80 to a GICC entry start address
in memory the resulting address may well be past the actual MADT end,
triggering a false negative).
Fix the BAD_MADT_GICC_ENTRY() macro by reshuffling the condition checks
and update them to always use the firmware version specific MADT GICC
entry length in order to carry out boundary checks.

synced between CPU and DMA device when swapping happens after mem

The cited patch added a type field to structures ib_ah and rdma_ah_attr.
Function mlx4_ib_query_ah() builds an rdma_ah_attr structure from the
data in an mlx4_ib_ah structure (which contains both an ib_ah structure
and an address vector).
For mlx4_ib_query_ah() to work properly, the type field in the contained
ib_ah structure must be set correctly.
In the outgoing MAD tunneling flow, procedure mlx4_ib_multiplex_mad()
paravirtualizes a MAD received from a slave and sends the processed
mad out over the wire. During this processing, it populates an
mlx4_ib_ah structure and calls mlx4_ib_query_ah().
The cited commit overlooked setting the type field in the contained
ib_ah structure before invoking mlx4_ib_query_ah(). As a result, the
type field remained uninitialized, and the rdma_ah_attr structure was
incorrectly built. This resulted in improperly built MADs being sent out
over the wire.
This patch properly initializes the type field in the contained ib_ah
structure before calling mlx4_ib_query_ah(). The rdma_ah_attr structure
is then generated correctly.

the peer will send the identical single packet request when its RNR

The fix is to release the held reference prior to the rnr nak exit.

ARM: imx6ul-14x14-evk: Fix suspend over nfs by phy
Right now attempting doing suspend/resume while root is mounted over NFS
hangs on imx6ul-14x14-evk. This is happening because ksz8081 phy fixups are
lost on resume.
Fix this by using equivalent devicetree properties instead of a phy fixup
and handling those properties on resume in the micrel driver.
In theory it might now be possible to remove the phy fixup from mach-imx6ul
entirely but it is possible that this would break other imx6ul boards which
use the same phy. The solution would be to patch their dts but it's not
clear how to identify affected boards.
This code is shared with imx6ull-14x14-evk but 6ull suspend needs an
unrelated patch: https://lkml.org/lkml/2017/5/30/584
This is something of a corner case so there is no CC: stable.
Changes since v1: https://lkml.org/lkml/2017/5/30/672
* Split a kszphy_config_reset function for stuff shared between
config_init and resume. Calling config_init directly could be an option but
on some HW variants it does extra stuff like parsing devicetree options.
That would not be appropriate for resume code.

Merge tag 'nand/fixes-for-4.12-rc3' of git://git.infradead.org/linux-mtd into MTD
From Boris:
"""
This pull request contains several fixes to the core and the tango
driver.
tango fixes:
* Add missing MODULE_DEVICE_TABLE() in tango_nand.c
* Update the number of corrected bitflips
core fixes:
* Fix a long standing memory leak in nand_scan_tail()
* Fix several bugs introduced by the per-vendor init/detection
infrastructure (introduced in 4.12)
* Add a static specifier to nand_ooblayout_lp_hamming_ops definition
"""
Pull Reiserfs and GFS2 fixes from Jan Kara:
"Fixes to GFS2 & Reiserfs for the fallout of the recent WRITE_FUA
cleanup from Christoph.
Fixes for other filesystems were already merged by respective
maintainers."
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:

Pull SCSI target fixes from Nicholas Bellinger:
"Here are the target-pending fixes for v4.12-rc4:
- ibmviscsis ABORT_TASK handling fixes that missed the v4.12 merge
window. (Bryant Ly and Michael Cyr)
- Re-add a target-core check enforcing WRITE overflow reject that was
relaxed in v4.3, to avoid unsupported iscsi-target immediate data
overflow. (nab)
- Fix a target-core-user OOPs during device removal. (MNC + Bryant
Ly)
- Fix a long standing iscsi-target potential issue where kthread exit
did not wait for kthread_should_stop(). (Jiang Yi)
- Fix a iscsi-target v3.12.y regression OOPs involving initial login
PDU processing during asynchronous TCP connection close. (MNC +
nab)
This is a little larger than usual for an -rc4, primarily due to the
iscsi-target v3.12.y regression OOPs bug-fix.
However, it's an important patch as MNC + Hannes where both able to
trigger it using a reduced iscsi initiator login timeout combined with
a backend taking a long time to complete I/Os during iscsi login
driven session reinstatement"
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
iscsi-target: Always wait for kthread_should_stop() before kthread exit
iscsi-target: Fix initial login PDU asynchronous socket close OOPs
tcmu: fix crash during device removal
target: Re-add check to reject control WRITEs with overflow data
ibmvscsis: Fix the incorrect req_lim_delta

When the transition of NO_STP -> KERNEL_STP was fixed by always calling
mod_timer in br_stp_start, it introduced a new regression which causes
the timer to be armed even when the bridge is down, and since we stop
the timers in its ndo_stop() function, they never get disabled if the
device is destroyed before it's upped.
To reproduce:
$ while :; do ip l add br0 type bridge hello_time 100; brctl stp br0 on;
ip l del br0; done;

Apparently multi-cos isn't working for bnx2x quite some time -
driver implements ndo_select_queue() to allow queue-selection
for FCoE, but the regular L2 flow would cause it to modulo the
fallback's result by the number of queues.
The fallback would return a queue matching the needed tc
[via __skb_tx_hash()], but since the modulo is by the number of TSS
queues where number of TCs is not accounted, transmission would always
be done by a queue configured into using TC0.
Fixes: ada7c19e6d ("bnx2x: use XPS if possible for bnx2x_select_queue instead of pure hash")

The NETLINK_F_LISTEN_ALL_NSID otion enables to listen all netns that have a
nsid assigned into the netns where the netlink socket is opened.
The nsid is sent as metadata to userland, but the existence of this nsid is
checked only for netns that are different from the socket netns. Thus, if
no nsid is assigned to the socket netns, NETNSA_NSID_NOT_ASSIGNED is
reported to the userland. This value is confusing and useless.
After this patch, only valid nsid are sent to userland.
