This commit adds a functionality to multiplex PCM frames into isochronous
packets and demultiplex PCM frames from isochronous packets for ALSA PCM
applications.
Fireface 800 voluntarily maintains resources for tx isochronous
communication. It performs reservation of isochronous channel and
allocation/update of bandwidth in some cases below:
- at a first request to allocation after bus resets
- at requests to allocation when further bandwidth is required
When request is grant and the unit is prepared, read data from
0x0000801c0008 represents isochronous channel for tx stream, then
the unit can handle requests to start communication. If driver
send the request without checking the register, the unit takes
panic to continue bus resets. The unit starts transmission of
tx packets after receiving several rx packets from driver.
I note that the unit can process tx/rx packets and generate/record
sound regardless of HOST LED.

The way to maintain isochronous resources on bus is different between
Fireface 400/800.
This commit is a preparation. This commit moves a function to allocate resource to

Fireface 400/800 use three modes against the number of data channels in
data block for both tx/rx packets.
This commit adds refactoring for it. Some enumerators are added to
represent each of mode and a function is added to calculate the mode
from sampling frequency code (sfc).

Both of Fireface 400/800 have the same register to switch frame fetching
mode regardless of difference of available number of PCM frames in
rx isochronous packet.

According to my memo at hand and saved records, writing 0x00000001 to
SND_FF_REG_FETCH_PCM_FRAMES disables fetching PCM frames in corresponding
channel, however current implement uses reversed logic. This results in
muted volume in device side during playback.
This commit corrects the bug.

An initial commit to add tracepoints for packets without CIP headers
uses different print formats for added tracepoints. However this is not
convenient for users/developers to prepare debug tools.

tracepoint
An initial commit to add tracepoints for packets without CIP headers
introduces a wrong assignment to 'data_blocks' value of
'out_packet_without_header' tracepoint.

In IEC 61883-1/6 engine of ALSA firewire stack, a packet handler has a
second argument for 'the number of bytes in payload of isochronous
packet'. However, an incoming packet handler without CIP header uses the
value as 'the number of quadlets in the payload'. This brings userspace
applications to receive the number of PCM frames as four times against
real time.
This commit fixes the bug.

Sergey reported that forwarding was no longer working
if fq packet scheduler was used.
This is caused by the recent switch to EDT model, since incoming
packets might have been timestamped by __net_timestamp()
__net_timestamp() uses ktime_get_real(), while fq expects packets
using CLOCK_MONOTONIC base.
The fix is to clear skb->tstamp in forwarding paths.

Since commit 7969e5c40dfd ("ip: discard IPv4 datagrams with overlapping
segments.") IPv4 reassembly code drops the whole queue whenever an
overlapping fragment is received. However, the test is written in a way
which detects duplicate fragments as overlapping so that in environments
with many duplicate packets, fragmented packets may be undeliverable.
Add an extra test and for (potentially) duplicate fragment, only drop the
new fragment rather than the whole queue. Only starting offset and length
are checked, not the contents of the fragments as that would be too
expensive. For similar reason, linear list ("run") of a rbtree node is not
iterated, we only check if the new fragment is a subset of the interval
covered by existing consecutive fragments.
v2: instead of an exact check iterating through linear list of an rbtree
node, only check if the new fragment is subset of the "run" (suggested
by Eric Dumazet)

marvell_nfc_wait_op() waits for completion during 'timeout_ms'
milliseconds before throwing an error. While the logic is fine, the
value of 'timeout_ms' is given by the core and actually correspond to
the maximum time the NAND chip will take to complete the
operation. Assuming there is no overhead in the propagation of the
interrupt signal to the the NAND controller (through the Ready/Busy
line), this delay does not take into account the latency of the
operating system. For instance, for a page write, the delay given by
the core is rounded up to 1ms. Hence, when the machine is over loaded,
there is chances that this timeout will be reached.
There are two ways to solve this issue that are not incompatible:
1/ Enlarge the timeout value (if so, how much?).
2/ Check after the waiting method if we did not miss any interrupt
because of the OS latency (an interrupt is still pending). In this
case, we assume the operation exited successfully.
We choose the second approach that is a must in all cases, with the
possibility to also modify the timeout value to be, e.g. at least 1
second in all cases.

Commit
379d98ddf413 ("x86: vdso: Use $LD instead of $CC to link")
accidentally broke unwinding from userspace, because ld would strip the
.eh_frame sections when linking.
Originally, the compiler would implicitly add --eh-frame-hdr when
invoking the linker, but when this Makefile was converted from invoking
ld via the compiler, to invoking it directly (like vmlinux does),
the flag was missed. (The EH_FRAME section is important for the VDSO
shared libraries, but not for vmlinux.)
Fix the problem by explicitly specifying --eh-frame-hdr, which restores
parity with the old method.

tipc_wait_for_cond() drops socket lock before going to sleep,
but tsk->group could be freed right after that release_sock().
So we have to re-check and reload tsk->group after it wakes up.
After this patch, tipc_wait_for_cond() returns -ERESTARTSYS when
tsk->group is NULL, instead of continuing with the assumption of
a non-NULL tsk->group.
(It looks like 'dsts' should be re-checked and reloaded too, but
it is a different bug.)
Similar for tipc_send_group_unicast() and tipc_send_group_anycast().

While most distributions long ago switched to the iproute2 suite
of utilities, which allow class-e (240.0.0.0/4) address assignment,
distributions relying on busybox, toybox and other forms of
ifconfig cannot assign class-e addresses without this kernel patch.
While CIDR has been obsolete for 2 decades, and a survey of all the
open source code in the world shows the IN_whatever macros are also
obsolete... rather than obsolete CIDR from this ioctl entirely, this
patch merely enables class-e assignment, sanely.

vr.mifi is indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
net/ipv6/ip6mr.c:1845 ip6mr_ioctl() warn: potential spectre issue 'mrt->vif_table' [r] (local cap)
net/ipv6/ip6mr.c:1919 ip6mr_compat_ioctl() warn: potential spectre issue 'mrt->vif_table' [r] (local cap)
Fix this by sanitizing vr.mifi before using it to index mrt->vif_table'
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The spdxcheck script currently falls over when confronted with a binary
file (such as Documentation/logo.gif). To avoid that, always open files
in binary mode and decode line-by-line, ignoring encoding errors.
One tricky case is when piping data into the script and reading it from
standard input. By default, standard input will be opened in text mode,
so we need to reopen it in binary mode.
The breakage only happens with python3 and results in a
UnicodeDecodeError (according to Uwe).

There is actually a space after "sp," like this,

Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space. Hence, it displays every stack as zero-size.
After this patch, checkpatch.pl is able to match the start of a
function's objdump, and is then able to calculate each function's stack
correctly.

migrate_page_move_mapping() expects pages with private data set to have
a page_count elevated by 1. This is what used to happen for xfs through
the buffer_heads code before the switch to iomap in commit 82cb14175e7d
("xfs: add support for sub-pagesize writeback without buffer_heads").
Not having the count elevated causes move_pages() to fail on memory
mapped files coming from xfs.
Make iomap compatible with the migrate_page_move_mapping() assumption by
elevating the page count as part of iomap_page_create() and lowering it
in iomap_page_release().
It causes the move_pages() syscall to misbehave on memory mapped files
from xfs. It does not not move any pages, which I suppose is "just" a
perf issue, but it also ends up returning a positive number which is out
of spec for the syscall. Talking to Michal Hocko, it sounds like
returning positive numbers might be a necessary update to move_pages()
anyway though
(https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz).
I only hit this in tests that verify that move_pages() actually moved
the pages. The test also got confused by the positive return from
move_pages() (it got treated as a success as positive numbers were not
expected and not handled) making it a bit harder to track down what's
going on.

The conversion of alpha to memblock as the early memory manager caused
boot to hang as described at [1].
The issue is caused because for CONFIG_DISCTONTIGMEM=y case,
memblock_add() is called using memory start PFN that had been rounded
down to the nearest 8Mb and it caused memblock to see more memory that
is actually present in the system.
Besides, memblock allocates memory from high addresses while bootmem was
using low memory, which broke the assumption that early allocations are
always accessible by the hardware.
This patch ensures that memblock_add() is using the correct PFN for the
memory start and forces memblock to use bottom-up allocations.

The get_mac_address() function is normally inline, but when it is
not, we get a warning that this configuration is broken:
WARNING: vmlinux.o(.text+0x4aff00): Section mismatch in reference from the function w90p910_ether_setup() to the function .init.text:get_mac_address()
The function w90p910_ether_setup() references
the function __init get_mac_address().
This is often because w90p910_ether_setup lacks a __init
Remove the __init to make it always do the right thing.

The old code always starts from fixed port for VMADDR_PORT_ANY. Sometimes
when VMM crashed, there is still orphaned vsock which is waiting for
close timer, then it could cause connection time out for new started VM
if they are trying to connect to same port with same guest cid since the
new packets could hit that orphaned vsock. We could also fix this by doing
more in vhost_vsock_reset_orphans, but any way, it should be better to start
from a random local port instead of a fixed one.

All previous docks and dongles that have supported this feature use
the RTL8153-AD chip.
RTL8153-BND is a new chip that will be used in upcoming Dell type-C docks.
It should be added to the whitelist of devices to activate MAC address
pass through.
Per confirming with Realtek all devices containing RTL8153-BND should
activate MAC pass through and there won't use pass through bit on efuse
like in RTL8153-AD.

* clk-imx7ulp:
clk: imx: imx7ulp: add arm hsrun mode clocks support
dt-bindings: clock: imx7ulp: add HSRUN mode related clocks
|
|
i.MX7ULP has a Cortex-A7 CPU which can run in RUN mode
or HSRUN mode, it is controlled in SMC1 module. The RUN
mode and HSRUN mode will use different clock source for
ARM, "divcore" for RUN mode and "hsrun_divcore" for HSRUN
mode, so the control bits in SMC1 module can be abstracted
as a HW clock mux, this patch adds HSRUN mode related
clocks in SCG1 module and adds "arm" clock in SMC1 module
to support RUN mode and HSRUN mode switch.
Latest clock tree in RUN mode as below:
firc 0 0 0 48000000 0 0 50000
firc_bus_clk 0 0 0 48000000 0 0 50000

There are HSRUN mode clock mux and divider in SCG1 module,
and SMC1 can control i.MX7ULP CPU to run in RUN mode or
HSRUN mode, the mode switch bits are actually a clock mux,
add these clocks for clock driver and dtb to use.

* clk-of:
clk: Use of_node_name_eq for node name comparisons
|
|
Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which all of these are.

Commit e1e6255c311b ("mtd: rawnand: omap2: convert driver to

and at the same time changed the struct device object passed to
dma_request_chan() (&pdev->dev instead of pdev->dev.parent).

nand_jedec_detect() should return 1 when the PARAM page parsing
succeeds, otherwise the core considers JEDEC detection failed and falls
back to ID-based detection.

- Proper suspend/resume on VersaClock5
* clk-vc5-suspend:
clk: vc5: Add suspend/resume support
|
|
Add simple suspend/resume handlers to the driver to restore the chip
configuration after resume. It is possible that the chip was configured
with non-default values before suspend-resume cycle and that the chip
is powered down during this cycle, so the configuration could get lost.

gcc_lpass_trig_clk is not used downstream, therefore there is no reason to
expect it to be needed for clients. Let's remove it because messing with
the clock has been observed to cause Linux hangs when the qdss_clk is
initialized by rpmcc.
