Hi,
For a brief moment I was tricked into thinking that:
In-kernel debugger (EXPERIMENTAL) (ACPI_DEBUGGER) [N/y/?] (NEW)
might be something useful. Better describe the feature to reduce
such confusion.

Because interrupt endpoints usually transmit such
small amounts of data, it seems pointless to prestart
transfers and try to get speed improvements. This
patch also sorts out a problem with CDC ECM function
where its notification endpoint gets stuck in busy
state and we continuously issue Update Transfer
commands.

The gianfar driver has recently been enabled on arm64 but fails to build
since it check the return value of platform_get_irq() against NO_IRQ. Fix
this by instead checking for a negative error code.
Even on ARM where this code was previously being built this check was
incorrect since platform_get_irq() returns a negative error code which
may not be exactly the (unsigned int)(-1) that NO_IRQ is defined to be.

This driver can be built on arm64 but relies on NO_IRQ to check the return
value of irq_of_parse_and_map() which fails to build on arm64 because the
architecture does not provide a NO_IRQ. Fix this to correctly check the
return value of irq_of_parse_and_map().
Even on ARM systems where the driver was previously used the check was
broken since on ARM NO_IRQ is -1 but irq_of_parse_and_map() returns 0 on
error.

The receive skb buffers can be preallocated when the link is opened
according to mtu size.
While testing on a network environment with not standard MTU (e.g. 3000),
a panic occurred if an incoming packet had a length greater than rx skb
buffer size. This is because the HW is programmed to copy, from the DMA,
an Jumbo frame and the Sw must check if the allocated buffer is enough to
store the frame.

In case of the st,tx-retime-src is missing from device-tree
(it's an optional field) the driver will invoke the strcasecmp to check
which clock has been selected and this is a bug; the else condition
is needed.
In the dwmac_setup, the "rs" variable, passed to the strcasecmp, was not
initialized and the compiler, depending on the options adopted, could
take it in some different part of the stack generating the hang in such
configuration.

When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
TRIM command results in I/O errors being reported in the log. There is
other similar error reported with TRIM and the SIL controller:
https://bugs.centos.org/view.php?id=5880
Apparently the controller doesn't support TRIM commands. This patch
disables TRIM support on the SATA SIL controller.

Current code doesn't update port value of Port Multiplier(PM) when
sending FIS of softreset to device, command will fail if FBS is
enabled.
There are two ways to fix the issue: the first is to disable FBS
before sending softreset command to PM device and the second is
to update port value of PM when sending command.
For the first way, i can't find any related rule in AHCI Spec. The
second way can avoid disabling FBS and has better performance.

I2C controller used in Keystone SoC has an undocumented peculiarity which
results in SDA-SCL margins being dependent on module clock. Driving high
capacity bus near its limits can result in STOP condition sometimes being
understood as REPEATED-START by slaves (or NACK instead of ACK, etc...).
Driving the module with higher clocks increases the margin between SDA and SCL
transitions, making the operations with higher bus rates more robust. Therefore,
target the module clock to 12MHz instead of 7MHz, still staying within
the specification limits.
Before the change STOP timing looked like this on 400kHz:
SDA ----------+ +----
\ /
\ /
+----+
(1)
SCL --+ +------------
\ /
\ /
+----+
(2)
While only point (1) signals STOP, point (2) could be incorrectly recognized as
repeated-START (almost no margin between SDA and SCL transitions).
After the change there is at least 600ns margin measured between SCL fall and
SDA fall during STOP generation:
SDA ------+ +----
\ /
\ /
+----+
SCL --+ +--------
\ /
\ /
+----+
->| |<- 600ns
->| |<- tSUSTO
So called tSUSTO (setup time for STOP condition) is still slightly higher than
600ns, so no problem here.

According to the datasheets the n factor for dividing the tclk is
2 to the power n on Allwinner SoCs, not 2 to the power n + 1 as it is
on other mv64xxx implementations.
I've contacted Allwinner about this and they have confirmed that the
datasheet is correct.
This commit fixes the clk-divider calculations for Allwinner SoCs
accordingly.

Originally OMAP MPUIO GPIO irqchip was implemented using Generic irq
chip, but after set of reworks Generic irq chip code was replaced by
common OMAP GPIO implementation and finally removed by
commit d2d05c65c40e ("gpio: omap: Fix regression for MPUIO interrupts").
Unfortunately, above commit left .irq_mask/unmask callbacks assigned
as below for MPUIO GPIO case:
irqc->irq_mask = irq_gc_mask_set_bit;
irqc->irq_unmask = irq_gc_mask_clr_bit;
This now causes boot failure on OMAP1 platforms, after
commit 450fa54cfd66 ("gpio: omap: convert to use generic irq handler")
which forces these callbacks to be called during GPIO IRQs mapping
from gpiochip_irq_map:

target_core_sbc's compare_and_write functionality suffers from taking
data at the wrong memory location when writing a CAW request to disk
when a SGL offset is non-zero.
This can happen with loopback and vhost-scsi fabric drivers when
SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.
Given the following sample LIO subtopology,
% targetcli ls /loopback/
o- loopback ................................. [1 Target]
o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3]
o- luns ................................... [2 LUNs]
o- lun0 ................ [iblock/ram0 (/dev/ram0)]
o- lun1 ................ [iblock/ram1 (/dev/ram1)]
% lsscsi -g
[3:0:1:0] disk LIO-ORG IBLOCK 4.0 /dev/sdc /dev/sg3
[3:0:1:1] disk LIO-ORG IBLOCK 4.0 /dev/sdd /dev/sg4
the following bug can be observed in Linux 4.3 and 4.4~rc1:
% perl -e 'print chr$_ for 0..255,reverse 0..255' >rand
% perl -e 'print "\0" x 512' >zero
% cat rand >/dev/sdd
% sg_compare_and_write -i rand -D zero --lba 0 /dev/sdd
% sg_compare_and_write -i zero -D rand --lba 0 /dev/sdd
Miscompare reported
% hexdump -Cn 512 /dev/sdd
00000000 0f 0e 0d 0c 0b 0a 09 08 07 06 05 04 03 02 01 00

Rather than writing all-zeroes as instructed with the -D file, it
corrupts the data in the sector by splicing some of the original
bytes in. The page of the first entry of cmd->t_data_sg includes the
CDB, and sg->offset is set to a position past the CDB. I presume that
sg->offset is also the right choice to use for subsequent sglist
members.

This patch fixes the following kernel warning because it avoids that
IRQs are disabled while ft_release_cmd() is invoked (fc_seq_set_resp()
invokes spin_unlock_bh()):

This patch addresses a race + use after free where the first
stage of COMPARE_AND_WRITE in compare_and_write_callback()
is rescheduled after the backend sends the secondary WRITE,
resulting in second stage compare_and_write_post() callback
completing in target_complete_ok_work() before the first
can return.
Because current code depends on checking se_cmd->se_cmd_flags
after return from se_cmd->transport_complete_callback(),
this results in first stage having SCF_COMPARE_AND_WRITE_POST
set, which incorrectly falls through into second stage CAW
processing code, eventually triggering a NULL pointer
dereference due to use after free.
To address this bug, pass in a new *post_ret parameter into
se_cmd->transport_complete_callback(), and depend upon this
value instead of ->se_cmd_flags to determine when to return
or fall through into ->queue_status() code for CAW.

This patch addresses a case where iscsi_target_do_tx_login_io()
fails sending the last login response PDU, after the RX/TX
threads have already been started.
The case centers around iscsi_target_rx_thread() not invoking
allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
from the failure path, resulting in RX thread hanging
indefinately on iscsi_conn->rx_login_comp.
Note this bug is a regression introduced by:

iscsi-target: Fix iscsit_start_kthreads failure OOPs
To address this bug, complete ->rx_login_complete for good
measure in the failure path, and immediately return from
RX thread context if connection state did not actually reach
full feature phase (TARG_CONN_STATE_LOGGED_IN).
