The PLIC integrated on the Vic_U7_Core integrated on the StarFive
JH7100 SoC actually supports 133 external interrupts. 127 of these
are exposed to the outside world; the remainder are used by other
devices that are part of the core-complex such as the L2 cache
controller. But all 133 interrupts are external interrupts as far
as the PLIC is concerned. Fix the property so that the driver can
manage these additional interrupts, which is important since the
interrupts for the L2 cache controller are enabled by default.

At the end of a message, the HW gets a reset in meson_spicc_unprepare_transfer(),
this resets the SPICC_CONREG register and notably the value set by the
Common Clock Framework.
This is problematic because:
- the register value CCF can be different from the corresponding CCF cached rate
- CCF is allowed to change the clock rate whenever the HW state
This introduces:
- local pow2 clock ops checking the HW state before allowing a clock operation
- separation of legacy pow2 clock patch and new enhanced clock path
- SPICC_CONREG datarate value is now value kepts across messages
It has been checked that:
- SPICC_CONREG datarate value is kept across messages
- CCF is only allowed to change the SPICC_CONREG datarate value when busy
- SPICC_CONREG datarate value is correct for each transfer
This didn't appear before commit 3e0cf4d3fc ("spi: meson-spicc: add a linear clock divider support")
because we recalculated and wrote the rate for each xfer.

To avoid allocation of the conntrack extension area when possible,
the default behaviour was changed to only allocate the event extension
if a userspace program is subscribed to a notification group.
Problem is that while 'conntrack -E' does enable the event allocation
behind the scenes, 'conntrack -E expect' does not: no expectation events
are delivered unless user sets
"net.netfilter.nf_conntrack_events" back to 1 (always on).
Fix the autodetection to also consider EXP type group.
We need to track the 6 event groups (3+3, new/update/destroy for events and
for expectations each) independently, else we'd disable events again
if an expectation group becomes empty while there is still an active
event group.

area_cache_get() is used to distribute cache->area and set cache->id,
and if cache->id is not 0 and cache->area->kref refcount is 0, it will
release the cache->area by nfp_cpp_area_release(). area_cache_get()
set cache->id before cpp->op->area_init() and nfp_cpp_area_acquire().
But if area_init() or nfp_cpp_area_acquire() fails, the cache->id is
is already set but the refcount is not increased as expected. At this
time, calling the nfp_cpp_area_release() will cause use-after-free.
To avoid the use-after-free, set cache->id after area_init() and
nfp_cpp_area_acquire() complete successfully.
Note: This vulnerability is triggerable by providing emulated device
equipped with specified configuration.

This reverts commit 258fafcd06.
The clang -Wformat warning is terminally broken, and the clang people
can't seem to get their act together.
This test program causes a warning with clang:
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%hhu\n", 'a');
}
resulting in
t.c:5:19: warning: format specifies type 'unsigned char' but the argument has type 'int' [-Wformat]
printf("%hhu\n", 'a');
~~~~ ^~~
%d
and apparently clang people consider that a feature, because they don't
want to face the reality of how either C character constants, C
arithmetic, and C varargs functions work.
The rest of the world just shakes their head at that kind of
incompetence, and turns off -Wformat for clang again.
And no, the "you should use a pointless cast to shut this up" is not a
valid answer. That warning should not exist in the first place, or at
least be optinal with some "-Wformat-me-harder" kind of option.
[ Admittedly, there's also very little reason to *ever* use '%hh[ud]' in
C, but what little reason there is is entirely about 'I want to see
only the low 8 bits of the argument'. So I would suggest nobody ever
use that format in the first place, but if they do, the clang
behavious is simply always wrong. Because '%hhu' takes an 'int'. It's
that simple. ]

Commit b32d45824a ("dm bufio: Add DM_BUFIO_CLIENT_NO_SLEEP flag")
added a "NO_SLEEP" mode, it replaces a mutex with a spinlock, and it
is only usable when the device is in read-only mode (because the write
path may be sleeping while holding the dm_bufio_client lock).
However, there are still two points where the code could sleep even in
read-only mode. One is in __get_unclaimed_buffer -> __make_buffer_clean.
The other is in __try_evict_buffer -> __make_buffer_clean. These functions
will call __make_buffer_clean which sleeps if the buffer is being read.
Fix these cases so that if c->no_sleep is set __make_buffer_clean
will not be called and the buffer will be skipped instead.

This uses a pseudo-linearization scheme with a 64k global buffer,
but BIG TCP arrival means IPv6 TCP stack can generate skbs
that exceed this size.
In practice, IRC commands are not expected to exceed 512 bytes, plus
this is interactive protocol, so we should not see large packets
in practice.
Given most IRC connections nowadays use TLS so this helper could also be
removed in the near future.

This uses a pseudo-linearization scheme with a 64k global buffer,
but BIG TCP arrival means IPv6 TCP stack can generate skbs
that exceed this size.
Use skb_linearize. It should be possible to rewrite this to properly
deal with segmented skbs (i.e., only do small chunk-wise accesses),
but this is going to be a lot more intrusive than this because every
helper function needs to get the sk_buff instead of a pointer to a raw
data buffer.
In practice, provided we're really looking at FTP control channel packets,
there should never be a case where we deal with huge packets.

With BIG TCP, packets generated by tcp stack may exceed 64kb.
Cap datalen at 64kb. The internal message format uses 16bit fields,
so no embedded message can exceed 64k size.
Multiple h323 messages in a single superpacket may now result
in a message to get treated as incomplete/truncated, but thats
better than scribbling past h323_buffer.
Another alternative suitable for net tree would be a switch to
skb_linearize().

For historical reason this code performs pseudo linearization of skbs
via skb_header_pointer and a global 64k buffer.
With arrival of BIG TCP, packets generated by TCP stack can exceed 64kb.
Rewrite this to only extract the needed header data. This also allows
to get rid of the locking.

A late ack is currently being sent at the end of a transfer due to
incorrect logic in mchp_corei2c_empty_rx(). Currently the Assert Ack
bit is being written to the controller's control reg after the last
byte has been received, causing it to sent another byte with the ack.
Instead, the AA flag should be written to the control register when
the penultimate byte is read so it is sent out for the last byte.

Fix i2c transfers using GPI DMA mode for all message types that do not set
the I2C_M_DMA_SAFE flag (e.g. SMBus "read byte").
In this case a bounce buffer is returned by i2c_get_dma_safe_msg_buf(),
and it has to synced back to the message after the transfer is done.
Add missing assignment of dma buffer in geni_i2c_gpi().
Set xferred in i2c_put_dma_safe_msg_buf() to true in case of no error to
ensure the sync-back of this dma buffer to the message.
