On RTL8411b the RX unit gets confused if the PHY is powered-down.
This was reported in [0] and confirmed by Realtek. Realtek provided
a sequence to fix the RX unit after PHY wakeup.

The issue itself seems to have been there longer, the Fixes tag
refers to where the fix applies properly.

 "Notable changes:

   - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver,
     as well as some other functions only used by drivers that haven't
     (yet?) made it upstream.

   - A fix for a bug in our handling of hardware watchpoints (eg. perf
     record -e mem: ...) which could lead to register corruption and
     kernel crashes.

   - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for
     vmalloc when using the Radix MMU.

   - A large but incremental rewrite of our exception handling code to
     use gas macros rather than multiple levels of nested CPP macros.

  And the usual small fixes, cleanups and improvements.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.3 kernel cycle:

  Core changes:

   - Device links can optionally be added between a pin control producer
     and its consumers. This will affect how the system power management
     is handled: a pin controller will not suspend before all of its
     consumers have been suspended.

     This was necessary for the ST Microelectronics STMFX expander and
     need to be tested on other systems as well: it makes sense to make
     this default in the long run.

     Right now it is opt-in per driver.

   - Drive strength can be specified in microamps. With decreases in
     silicon technology, milliamps isn't granular enough, let's make it
     possible to select drive strengths in microamps.

     Right now the Meson (AMlogic) driver needs this.

  New drivers:

   - New subdriver for the Tegra 194 SoC.

   - New subdriver for the Qualcomm SDM845.

   - New subdriver for the Qualcomm SM8150.

   - New subdriver for the Freescale i.MX8MN (Freescale is now a product
     line of NXP).

   - New subdriver for Marvell MV98DX1135.

  Driver improvements:

   - The Bitmain BM1880 driver now supports pin config in addition to
     muxing.

   - The Qualcomm drivers can now reserve some GPIOs as taken aside and
     not usable for users. This is used in ACPI systems to take out some
     GPIO lines used by the BIOS so that noone else (neither kernel nor
     userspace) will play with them by mistake and crash the machine.

   - A slew of refurbishing around the Aspeed drivers (board management
     controllers for servers) in preparation for the new Aspeed AST2600
     SoC.

   - A slew of improvements over the SH PFC drivers as usual.

   - Misc cleanups and fixes"

Pull io_uring updates from Jens Axboe:
 "This contains:

   - Support for recvmsg/sendmsg as first class opcodes.

     I don't envision going much further down this path, as there are
     plans in progress to support potentially any system call in an
     async fashion through io_uring. But I think it does make sense to
     have certain core ops available directly, especially those that can
     support a "try this non-blocking" flag/mode. (me)

   - Handle generic short reads automatically.

     This can happen fairly easily if parts of the buffered read is
     cached. Since the application needs to issue another request for
     the remainder, just do this internally and save kernel/user
     roundtrip while providing a nicer more robust API. (me)

   - Support for linked SQEs.

     This allows SQEs to depend on each other, enabling an application
     to eg queue a read-from-this-file,write-to-that-file pair. (me)

   - Fix race in stopping SQ thread (Jackie)"

Commit 0e5a610b ("ppp: mppe: switch to RC4 library interface"),
which was merged through the crypto tree for v5.3, changed ppp_mppe.c to
use the new arc4_crypt() library function rather than access RC4 through
the dynamic crypto_skcipher API.

Meanwhile commit aad1dcc4 ("ppp: mppe: Add softdep to arc4") was
merged through the net tree and added a module soft-dependency on "arc4".

The latter commit no longer makes sense because the code now uses the
"libarc4" module rather than "arc4", and also due to the direct use of
arc4_crypt(), no module soft-dependency is required.

So revert the latter commit.

 "In this release there are a significant amounts of consolidations and

  bios directly; new bulkstat ioctls to return v5 fs inode information
  (and fix all the padding problems of the old ioctl); the beginnings of
  multithreaded inode walks (e.g. quotacheck); and a reduction in memory
  usage in the online scrub code leading to reduced runtimes.

   - Refactor inode geometry calculation into a single structure instead
     of open-coding pieces everywhere.

   - Add online repair to build options.

   - Remove unnecessary function call flags and functions.

   - Claim maintainership of various loose xfs documentation and header
     files.

   - Use struct bio directly for log buffer IOs instead of struct
     xfs_buf.

   - Reduce log item boilerplate code requirements.

   - Merge log item code spread across too many files.

   - Fix a memory allocation miscalculation in the new log bio code

   - Fix bisection problems

   - Fix a crash in ioend processing caused by tripping over freeing of
     preallocated transactions

   - Split out a generic inode walk mechanism from the bulkstat code,
     hook up all the internal users to use the walking code, then clean
     up bulkstat to serve only the bulkstat ioctls.

   - Add a multithreaded iwalk implementation to speed up quotacheck on
     fast storage with many CPUs.

   - Remove unnecessary return values in logging teardown functions.

   - Supplement the bstat and inogrp structures with new bulkstat and
     inumbers structures that have all the fields we need for v5
     filesystem features and none of the padding problems of their
     predecessors.

   - Wire up new ioctls that use the new structures with a much simpler
     bulk_ireq structure at the head instead of the pointerhappy mess we
     had before.

   - Enable userspace to constrain bulkstat returns to a single AG or a
     single special inode so that we can phase out a lot of geometry
     guesswork in userspace.

   - Reduce memory consumption and zeroing overhead in extended
     attribute scrub code.

The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several
hundred kilobytes of kernel stack space. One gets inlined into the other,
which causes the stack usage to be combined beyond the warning limit
when building with clang:

drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=]

Restructuring cudbg_collect_mem_region() lets clang do the same
optimization that gcc does and reuse the stack slots as it can
see that the large variables are never used together.

A better fix might be to avoid using cudbg_meminfo on the stack
altogether, but that requires a larger rewrite.

tipc_named_node_up() creates a skb list. It passes the list to
tipc_node_xmit() which has some code paths that can call
skb_queue_purge() which relies on the list->lock being initialised.

The spin_lock is only needed if the messages end up on the receive path
but when the list is created in tipc_named_node_up() we don't
necessarily know if it is going to end up there.

Once all the skb list users are updated in tipc it will then be possible
to update them to use the unlocked variants of the skb list functions
and initialise the lock when we know the message will follow the receive
path.

Fix bugs in NFP flower match offload

This patchset contains bug fixes for corner cases in the match fields of
flower offloads. The patches ensure that flows that should not be
supported are not (incorrectly) offloaded. These include rules that match
on layer 3 and/or 4 data without specified ethernet or ip protocol fields.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Flower rules on the NFP firmware are able to match on an IP protocol
field. When parsing rules in the driver, unknown IP protocols are only
rejected when further matches are to be carried out on layer 4 fields, as
the firmware will not be able to extract such fields from packets.

L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if
an IP protocol is specified. This leaves a loophole whereby a rule that
attempts to match on transport layer information such as port numbers but
does not explicitly give an IP protocol type can be incorrectly offloaded
(in this case with wildcard port numbers matches).

Fix this by rejecting the offload of flows that attempt to match on L4
information, not only when matching on an unknown IP protocol type, but
also when the protocol is wildcarded.

NFP firmware does not explicitly match on an ethernet type field. Rather,
each rule has a bitmask of match fields that can be used to infer the
ethernet type.

Currently, if a flower rule contains an unknown ethernet type, a check is
carried out for matches on other fields of the packet. If matches on
layer 3 or 4 are found, then the offload is rejected as firmware will not
be able to extract these fields from a packet with an ethernet type it
does not currently understand.

However, if a rule contains an unknown ethernet type without any L3 (or
above) matches then this will effectively be offloaded as a rule with a
wildcarded ethertype. This can lead to misclassifications on the firmware.

Fix this issue by rejecting all flower rules that specify a match on an
unknown ethernet type.

Further ensure correct offloads by moving the 'L3 and above' check to any
rule that does not specify an ethernet type and rejecting rules with
further matches. This means that we can still offload rules with a
wildcarded ethertype if they only match on L2 fields but will prevent
rules which match on further fields that we cannot be sure if the firmware
will be able to extract.

Introduce new function tcf_block_non_null_shared() that verifies block
pointer before dereferencing it to obtain index. Use the function in
tc_indr_block_ing_cmd() to prevent NULL pointer dereference.

dma_addr_t may be 64-bit wide on 32-bit architectures, so it is not
valid to cast between it and a pointer:

drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_submit_si':
drivers/net/ethernet/ti/davinci_cpdma.c:1047:12: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_idle_submit_mapped':

drivers/net/ethernet/ti/davinci_cpdma.c:1164:12: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

Solve this by using two separate members in 'struct submit_info'.
Since this avoids the use of the 'flag' member, the structure does
not even grow in typical configurations.

When a vport is deleted, the maximum headroom size would be changed.
If the vport which has the largest headroom is deleted,
the new max_headroom would be set.
But, if the new headroom size is equal to the old headroom size,
updating routine is unnecessary.

Pull dma-mapping updates from Christoph Hellwig:

 - move the USB special case that bounced DMA through a device bar into
   the USB code instead of handling it in the common DMA code (Laurentiu
   Tudor and Fredrik Noring)

 - don't dip into the global CMA pool for single page allocations
   (Nicolin Chen)

 - fix a crash when allocating memory for the atomic pool failed during
   boot (Florian Fainelli)

 - move support for MIPS-style uncached segments to the common code and
   use that for MIPS and nios2 (me)

 - make support for DMA_ATTR_NON_CONSISTENT and
   DMA_ATTR_NO_KERNEL_MAPPING generic (me)

 - convert nds32 to the generic remapping allocator (me)
