When setting speed to 100G via ethtool (AN is set to off), only 25G*4 is
configured while the user, who has an advanced HW which supports
extended PTYS, expects also 50G*2 to be configured.
With this patch, when extended PTYS mode is available, configure
PTYS via extended fields.

Add a missing value in translation of PTYS ext_eth_proto_oper to its
corresponding speed. When ext_eth_proto_oper bit 10 is set, ethtool
shows unknown speed. With this fix, ethtool shows speed is 100G as
expected.

When the user changes prio2buffer mapping while global pause is
enabled, mlx5 driver incorrectly sets all active buffers
(buffer that has at least one priority mapped) to lossy.
Solution:
If global pause is enabled, set all the active buffers to lossless
in prio2buffer command.
Also, add error message when buffer size is not enough to meet
xoff threshold.

Cited patch changed (channel index, tc) => (TXQ index) mapping to be a
static one, in order to keep indices consistent when changing number of
channels or TCs.
For 32 channels (OOB) and 8 TCs, real num of TXQs is 256.
When reducing the amount of channels to 8, the real num of TXQs will be
changed to 64.
This indices method is buggy:
- Channel #0, TC 3, the TXQ index is 96.
- Index 8 is not valid, as there is no such TXQ from driver perspective
(As it represents channel #8, TC 0, which is not valid with the above
configuration).
As part of driver's select queue, it calls netdev_pick_tx which returns an
index in the range of real number of TXQs. Depends on the return value,
with the examples above, driver could have returned index larger than the
real number of tx queues, or crash the kernel as it tries to read invalid
address of SQ which was not allocated.
Fix that by allocating sequential TXQ indices, and hold a new mapping
between (channel index, tc) => (real TXQ index). This mapping will be
updated as part of priv channels activation, and is used in
mlx5e_select_queue to find the selected queue index.
The existing indices mapping (channel_tc2txq) is no longer needed, as it
is used only for statistics structures and can be calculated on run time.
Delete its definintion and updates.

====================
s390/qeth: fixes 2019-12-05
please apply the following fixes to your net tree.
The first two patches target the RX data path, the third fixes a memory
leak when shutting down a qeth device.
====================

The cio layer's intparm logic does not align itself well with how qeth
manages cmd IOs. When an active IO gets terminated via halt/clear, the
corresponding IRQ's intparm does not reflect the cmd buffer but rather
the intparm that was passed to ccw_device_halt() / ccw_device_clear().
This behaviour was recently clarified in
commit b91d9e67e50b ("s390/cio: fix intparm documentation").
As a result, qeth_irq() currently doesn't cancel a cmd that was
terminated via halt/clear. This primarily causes us to leak
card->read_cmd after the qeth device is removed, since our IO path still
holds a refcount for this cmd.
For qeth this means that we need to keep track of which IO is pending on
a device ('active_cmd'), and use this as the intparm when calling
halt/clear. Otherwise qeth_irq() can't match the subsequent IRQ to its
cmd buffer.
Since we now keep track of the _expected_ intparm, we can also detect
any mismatch; this would constitute a bug somewhere in the lower layers.
In this case cancel the active cmd - we effectively "lost" the IRQ and
should not expect any further notification for this IO.

When the RX path builds non-linear skbs, the packet headers can
currently spill over into page fragments. Depending on the packet type
and what fields we need to access in the headers, this could cause us
to go past the end of skb->data.
So for non-linear packets, copy precisely the length of the necessary
headers ('linear_len') into skb->data.
And don't copy more, upper-level protocols will peel whatever additional
packet headers they need.

Depending on a packet's type, the RX path needs to access fields in the
packet headers and thus requires a minimum packet length.
Enforce this length when building the skb.
On the other hand a single runt packet is no reason to drop the whole
RX buffer. So just skip it, and continue processing on the next packet.

Since commit 2b3e88ea6528 ("net: phy: improve phy state checking")
phy_start_aneg() expects phy state to be >= PHY_UP. Call phy_start()
before calling phy_start_aneg() during probe so that autonegotiation
is initiated.
As phy_start() takes care of calling phy_start_aneg(), drop the explicit
call to phy_start_aneg().
Network fails without this patch on Octeon TX.

hsr_dev_xmit() calls hsr_port_get_hsr() to find master node and that would
return NULL if master node is not existing in the list.
But hsr_dev_xmit() doesn't check return pointer so a NULL dereference
could occur.
Test commands:
ip netns add nst
ip link add veth0 type veth peer name veth1
ip link add veth2 type veth peer name veth3

7c20f11680a4 ("bio-integrity: stop abusing bi_end_io") moves
bio_integrity_free from bio_uninit() to bio_integrity_verify_fn()
and bio_endio(). This way looks wrong because bio may be freed
without calling bio_endio(), for example, blk_rq_unprep_clone() is
called from dm_mq_queue_rq() when the underlying queue of dm-mpath
is busy.
So memory leak of bio integrity data is caused by commit 7c20f11680a4.
Fixes this issue by re-adding bio_integrity_free() to bio_uninit().

The conversion to properties changed one assignment and
missed three other assignments in the same file, fix it
up so the platform compiles.
The bug was reported by a few build bots but noone noticed.
I noticed it when making other changes to the PXA platforms.

ARMv8 Juno fixes for v5.5
Couple of fixes:
1. Fix for UART clock frequency on all Juno variants that exist since
the platform was added. This is mainly due to incorrect Juno SoC
TRM that was referred during initial development days
2. Drop "dma-ranges" property for now as they are triggering loads of
warning on boot

snoop_file_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL

Links are created by chaining requests through req->list with an
exception that head uses req->link_list. (e.g. link_list->list->list)
Because of that, io_req_link_next() needs complex splicing to advance.
Link them all through list_list. Also, it seems to be simpler and more

When a root user or a user with CAP_SYS_ADMIN privilege uses any
trace_imc performance monitoring unit events, to monitor application
or KVM threads, it may result in a checkstop (System crash).
The cause is frequent switching of the "trace/accumulation" mode of
the In-Memory Collection hardware (LDBAR).
This patch disables the trace_imc PMU unit entirely to avoid
triggering the checkstop. A future patch will reenable it at a later
stage once a workaround has been developed.

export_imc_mode_and_cmd() function which creates the debugfs interface
for imc-mode and imc-command, is invoked when each nest pmu units is
registered.
When the first nest pmu unit is registered, export_imc_mode_and_cmd()
creates 'imc' directory under `/debug/powerpc/`. In the subsequent
invocations debugfs_create_dir() function returns, since the directory
already exists.
The recent commit <c33d442328f55> (debugfs: make error message a bit
more verbose), throws a warning if we try to invoke
`debugfs_create_dir()` with an already existing directory name.
Address this warning by making the debugfs directory registration in
the opal_imc_counters_probe() function, i.e invoke
export_imc_mode_and_cmd() function from the probe function.

For jited bpf program, if the subprogram count is 1, i.e.,
there is no callees in the program, prog->aux->func will be NULL
and prog->bpf_func points to image address of the program.
If there is more than one subprogram, prog->aux->func is populated,
and subprogram 0 can be accessed through either prog->bpf_func or
prog->aux->func[0]. Other subprograms should be accessed through
prog->aux->func[subprog_id].
This patch fixed a bug in check_attach_btf_id(), where
prog->aux->func[subprog_id] is used to access any subprogram which
caused a segfault like below:

The UML port uses 4 and 5 level fixups to support higher level page
table directories in the generic VM code.
Implement primitives necessary for the 4th level folding, add walks of
p4d level where appropriate and drop usage of __ARCH_USE_5LEVEL_HACK.

32-bit version of sparc has three-level page tables and can use
pgtable-nopud and folding of the upper layers.
Replace usage of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h and adjust page table manipulation
macros and functions accordingly.
