igb: Use an advanced ctx descriptor for launchtime
On i210, Launchtime (TxTime) requires the usage of an "Advanced
Transmit Context Descriptor" for retrieving the timestamp of a packet.
The igb driver correctly builds such descriptor on the segmentation
flow (i.e. igb_tso()) or on the checksum one (i.e. igb_tx_csum()), but the
feature is broken for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set,
which happens due to an early return on igb_tx_csum().
This flag is only set by the kernel when a VLAN interface is used,
thus we can't just rely on it. Here we are fixing this issue by checking
if launchtime is enabled for the current tx_ring before performing the
early return.

This series contains bug fixes to the ice driver.
Anirudh provides several fixes, starting with static analysis fixes by
replacing a bitwise-and with a constant value and replace "magic"
numbers with defines. Fixed the control queue processing by removing
unnecessary read/writes to registers, as well as getting a accurate
value for "pending". Added additional checks to avoid NULL pointer
dereferences. Fixed up code formatting issues, by cleaning up code
comments and coding style.
Bruce cleans up a duplicate check for owner, within the same function.
Also cleans up interrupt causes that are not handled or applicable.
Fix checkpatch warning about the use of bool in structures due to the
wasted space and size of bool, so convert struct members to u8 instead.
Jake fixes a number of potential bugs in the reporting of stats via
ethtool, by simply reporting all the queue statistics, even for the
queues that are not activated. Fixed a compiler warning, as well as
make the code a bit cleaner but just using order_base_2() for

Currently, we use a combination of ilog2 and is_power_of_2() to
calculate the next power of 2 for the qcount. This appears to be causing
a warning on some combinations of GCC and the Linux kernel:
This appears to because because GCC realizes that qcount could be zero
in some circumstances and thus attempts to link against the
intentionally undefined ___ilog2_NaN function.
The order_base_2 function is intentionally defined to return 0 when
passed 0 as an argument, and thus will be safe to use here.

ice: Report stats for allocated queues via ethtool stats
It is not safe to have the string table for statistics change order or
size over the lifetime of a given netdevice. This is because of the
nature of the 3-step process for obtaining stats. First, user space
performs a request for the size of the strings table. Second it performs
a separate request for the strings themselves, after allocating space
for the table. Third, it requests the stats themselves, also allocating
space for the table.
If the size decreased, there is potential to see garbage data or stats
values. In the worst case, we could potentially see stats values become
mis-aligned with their strings, so that it looks like a statistic is
being reported differently than it actually is.
Even worse, if the size increased, there is potential that the strings
table or stats table was not allocated large enough and the stats code
could access and write to memory it should not, potentially resulting in
undefined behavior and system crashes.
It isn't even safe if the size always changes under the RTNL lock. This
is because the calls take place over multiple user space commands, so it
is not possible to hold the RTNL lock for the entire duration of
obtaining strings and stats. Further, not all consumers of the ethtool
API are the user space ethtool program, and it is possible that one
assumes the strings will not change (valid under the current contract),
and thus only requests the stats values when requesting stats in a loop.
Finally, it's not possible in the general case to detect when the size
changes, because it is quite possible that one value which could impact
the stat size increased, while another decreased. This would result in
the same total number of stats, but reordering them so that stats no
longer line up with the strings they belong to. Since only size changes
aren't enough, we would need some sort of hash or token to determine
when the strings no longer match. This would require extending the
ethtool stats commands, but there is no more space in the relevant
structures.
The real solution to resolve this would be to add a completely new API
for stats, probably over netlink.
In the ice driver, the only thing impacting the stats that is not
constant is the number of queues. Instead of reporting stats for each
used queue, report stats for each allocated queue. We do not change the
number of queues allocated for a given netdevice, as we pass this into
the alloc_etherdev_mq() function to set the num_tx_queues and
num_rx_queues.
This resolves the potential bugs at the slight cost of displaying many
queue statistics which will not be activated.

net_sched: fix unused variable warning in stmmac
The new tcf_exts_for_each_action() macro doesn't reference its
arguments when CONFIG_NET_CLS_ACT is disabled, which leads to
a harmless warning in at least one driver:
drivers/net/ethernet/stmicro/stmmac/stmmac_tc.c: In function 'tc_fill_actions':
drivers/net/ethernet/stmicro/stmmac/stmmac_tc.c:64:6: error: unused variable 'i' [-Werror=unused-variable]
Adding a cast to void lets us avoid this kind of warning.

just the one that caused the warning.

sch_cake: Fix TC filter flow override and expand it to hosts as well
The TC filter flow mapping override completely skipped the call to
cake_hash(); however that meant that the internal state was not being
updated, which ultimately leads to deadlocks in some configurations. Fix
that by passing the overridden flow ID into cake_hash() instead so it can
react appropriately.
In addition, the major number of the class ID can now be set to override
the host mapping in host isolation mode. If both host and flow are
overridden (or if the respective modes are disabled), flow dissection and
hashing will be skipped entirely; otherwise, the hashing will be kept for
the portions that are not set by the filter.

bpf: sockmap: write_space events need to be passed to TCP handler
When sockmap code is using the stream parser it also handles the write
space events in order to handle the case where (a) verdict redirects
skb to another socket and (b) the sockmap then sends the skb but due
to memory constraints (or other EAGAIN errors) needs to do a retry.
But the initial code missed a third case where the
skb_send_sock_locked() triggers an sk_wait_event(). A typically case
would be when sndbuf size is exceeded. If this happens because we
do not pass the write_space event to the lower layers we never wake
up the event and it will wait for sndtimeo. Which as noted in ktls
fix may be rather large and look like a hang to the user.
To reproduce the best test is to reduce the sndbuf size and send
1B data chunks to stress the memory handling. To fix this pass the
event from the upper layer to the lower layer.

tls: possible hang when do_tcp_sendpages hits sndbuf is full case
Currently, the lower protocols sk_write_space handler is not called if
TLS is sending a scatterlist via tls_push_sg. However, normally
tls_push_sg calls do_tcp_sendpage, which may be under memory pressure,
that in turn may trigger a wait via sk_wait_event. Typically, this
happens when the in-flight bytes exceed the sdnbuf size. In the normal
case when enough ACKs are received sk_write_space() will be called and
the sk_wait_event will be woken up allowing it to send more data
and/or return to the user.
But, in the TLS case because the sk_write_space() handler does not
wake up the events the above send will wait until the sndtimeo is
exceeded. By default this is MAX_SCHEDULE_TIMEOUT so it look like a
hang to the user (especially this impatient user). To fix this pass
the sk_write_space event to the lower layers sk_write_space event
which in the TCP case will wake any pending events.
I observed the above while integrating sockmap and ktls. It
initially appeared as test_sockmap (modified to use ktls) occasionally
hanging. To reliably reproduce this reduce the sndbuf size and stress
the tls layer by sending many 1B sends. This results in every byte
needing a header and each byte individually being sent to the crypto
layer.

Pull RISC-V updates from Palmer Dabbelt:
"This contains some major improvements to the RISC-V port, including
the necessary interrupt controller and timer support to actually make
it to userspace. Support for three devices has been added:
- the ISA-mandated timers on RISC-V systems.
- the ISA-mandated first-level interrupt controller on RISC-V
systems, which is handled as part of our core arch code because
it's very small and tightly tied to the ISA.
- SiFive's platform-level interrupt controller, which talks to the
actual devices.
In addition to these new devices, there are a handful of cleanups all
over the RISC-V tree:
- build fixes for various configurations:
* A fix to the vDSO build's makefile so it respects CFLAGS.
* The addition of __lshrti3, a libgcc derived function necessary
for some 32-bit configurations.
* !SMP && PERF_EVENTS
- Cleanups to the arch code to remove the remnants of old versions of
the drivers that were just properly submitted.
* Some dead code from the timer driver, most of which wasn't ever
even compiled.
* Cleanups of some interrupt #defines, which are now local to the
interrupt handling code.
- Fixes to ptrace(), which while not being sufficient to fully make
GDB work are at least sufficient to get simple GDB tasks to work.
- Early printk support via RISC-V's architecturally mandated SBI
console device.
- A fix to our early debug trap handler to ensure it's always
aligned.
These patches have all been through a fairly extensive review process,
but as this enables a whole pile of functionality (ie, userspace) I'm
confident we'll need to submit a few more patches. The only concrete
issues I know about are the sys_riscv_flush_icache patches, but as I
managed to screw those up on Friday I figured it'd be best to let them
bake another week.
This tag boots a Fedora root filesystem on QEMU's master branch for

pcmcia: remove long deprecated pcmcia_request_exclusive_irq() function
This function was created as a deprecated fallback case back in 2010 by
commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy
cases.
Actual in-kernel users haven't been around for a long while. The last

deprecate the '__deprecated' attribute warnings entirely and for good
We haven't had lots of deprecation warnings lately, but the rdma use of
it made them flare up again.
They are not useful. They annoy everybody, and nobody ever does
anything about them, because it's always "somebody elses problem". And
when people start thinking that warnings are normal, they stop looking
at them, and the real warnings that mean something go unnoticed.
If you want to get rid of a function, just get rid of it. Convert every
user to the new world order.
And if you can't do that, then don't annoy everybody else with your
marking that says "I couldn't be bothered to fix this, so I'll just spam
everybody elses build logs with warnings about my laziness".
Make a kernelnewbies wiki page about things that could be cleaned up,
write a blog post about it, or talk to people on the mailing lists. But
don't add warnings to the kernel build about cleanup that you think
should happen but you aren't doing yourself.

a list by an idr
- for packet-based transports (virtio/rdma) validate that the packet
length matches what the header says
- a few race condition fixes found by syzkaller
- missing argument check when NULL device is passed in sys_mount
- a few virtio fixes
- some spelling and style fixes"

mm/hmm.c: remove unused variables align_start and align_end
Variables align_start and align_end are being assigned but are never
used hence they are redundant and can be removed.
Cleans up clang warnings:
warning: variable 'align_start' set but not used [-Wunused-but-set-variable]
warning: variable 'align_size' set but not used [-Wunused-but-set-variable]
