Change the counter name DLFT_CCERROR to DLFT_CCFINISH on IBM z15.
This counter counts completed DEFLATE instructions with exit code
0, 1 or 2. Since exit code 0 means success and exit code 1 or 2
indicate errors, change the counter name to avoid confusion.
This counter is incremented each time the DEFLATE instruction
completed regardless if an error was detected or not.

Although vmlinux.lds.S smells like an assembly file and is compiled
with __ASSEMBLY__ defined, it's actually just fed to the preprocessor to
create our linker script. This means that any assembly macros defined
by headers that it includes will result in a helpful link error:
| aarch64-linux-gnu-ld:./arch/arm64/kernel/vmlinux.lds:1: syntax error
In preparation for an arm64-private asm/rwonce.h implementation, which
will end up pulling assembly macros into linux/compiler.h, reduce the
number of headers we include directly and transitively in vmlinux.lds.S

Since commit 76ebbe78f739 ("locking/barriers: Add implicit
smp_read_barrier_depends() to READ_ONCE()"), there is no need to use
smp_read_barrier_depends() outside of the Alpha architecture code.
Unfortunately, there is precisely _one_ user in the vhost code, and
there isn't an obvious READ_ONCE() access making the barrier
redundant. However, on closer inspection (thanks, Jason), it appears
that vring synchronisation between the producer and consumer occurs via
the 'avail_idx' field, which is followed up by an rmb() in
vhost_get_vq_desc(), making the read_barrier_depends() redundant on
Alpha.
Jason says:
| I'm also confused about the barrier here, basically in driver side
| we did:
|
| 1) allocate pages
| 2) store pages in indirect->addr
| 3) smp_wmb()
| 4) increase the avail idx (somehow a tail pointer of vring)
|
| in vhost we did:
|
| 1) read avail idx
| 2) smp_rmb()
| 3) read indirect->addr
| 4) read from indirect->addr
|
| It looks to me even the data dependency barrier is not necessary
| since we have rmb() which is sufficient for us to the correct
| indirect->addr and driver are not expected to do any writing to
| indirect->addr after avail idx is increased
Remove the redundant barrier invocation.

Rather then relying on the core code to use smp_read_barrier_depends()
as part of the READ_ONCE() definition, instead override __READ_ONCE()
in the Alpha code so that it generates the required mb() and then
implement smp_load_acquire() using the new macro to avoid redundant
back-to-back barriers from the generic implementation.

The meat and potatoes of READ_ONCE() is defined by the __READ_ONCE()
macro, which uses a volatile casts in an attempt to avoid tearing of
byte, halfword, word and double-word accesses. Allow this to be

barriers are also required.

Pulling header files directly out of the kernel sources for inclusion in
userspace programs is highly error prone, not least because it bypasses
the kbuild infrastructure entirely and so may end up referencing other
header files that have not been generated.
Subsequent patches will cause compiler.h to pull in the ungenerated
asm/rwonce.h file via filter.h, breaking the build for tools/bpf:
| $ make -C tools/bpf
| make: Entering directory '/linux/tools/bpf'
| CC bpf_jit_disasm.o
| LINK bpf_jit_disasm
| CC bpf_dbg.o
| In file included from /linux/include/uapi/linux/filter.h:9,
| from /linux/tools/bpf/bpf_dbg.c:41:
| /linux/include/linux/compiler.h:247:10: fatal error: asm/rwonce.h: No such file or directory
| #include <asm/rwonce.h>
| ^~~~~~~~~~~~~~
| compilation terminated.
| make: *** [Makefile:61: bpf_dbg.o] Error 1
| make: Leaving directory '/linux/tools/bpf'
Take a copy of the installed version of linux/filter.h (i.e. the one
created by the 'headers_install' target) into tools/include/uapi/linux/
and adjust the BPF tool Makefile to reference the local include
directories instead of those in the main source tree.

The commits "xfrm: Move dst->path into struct xfrm_dst"
and "net: Create and use new helper xfrm_dst_child()."
changed xfrm bundle handling under the assumption
that xdst->path and dst->child are not a NULL pointer
only if dst->xfrm is not a NULL pointer. That is true
with one exception. If the xfrm hold queue is used
to wait until a SA is installed by the key manager,
we create a dummy bundle without a valid dst->xfrm
pointer. The current xfrm bundle handling crashes
in that case. Fix this by extending the NULL check
of dst->xfrm with a test of the DST_XFRM_QUEUE flag.

It fails to boot the v5.8-rc4 kernel with CONFIG_KASAN because kasan_init
and kasan_early_init use uninitialized __sbi_rfence as executing the
tlb_flush_all(). Actually, at this moment, only the CPU which is
responsible for the system initialization enables the MMU. Other CPUs are
parking at the .Lsecondary_start. Hence the tlb_flush_all() is able to be
replaced by local_tlb_flush_all() to avoid using uninitialized
__sbi_rfence.

Commit 02288248b051 ("tipc: eliminate gap indicator from ACK messages")
eliminated sending of the 'gap' indicator in regular ACK messages and
only allowed to build NACK message with enabled probe/probe_reply.
However, necessary correction for building NACK message was missed
in tipc_link_timeout() function. This leads to significant delay and
link reset (due to retransmission failure) in lossy environment.
This commit fixes it by setting the 'probe' flag to 'true' when
the receive deferred queue is not empty. As a result, NACK message
will be built to send back to another peer.

of_reset_control_get_exclusive() failed. Add the missed call to fix it.

The fragment packets do defrag in tcf_ct_handle_fragments
will clear the skb->cb which make the qdisc_skb_cb clear
too. So the qdsic_skb_cb should be store before defrag and
restore after that.
It also update the pkt_len after all the
fragments finish the defrag to one packet and make the
following actions counter correct.

These patches address an ethtool show regs problem, some locking sightings,
and issues with RSS hash and filter_id tracking after a managed FW update.

The ionic_wait_on_bit_lock() was a open-coded mutex knock-off
used only for protecting the queue reset operations, and there
was no reason not to use the real thing. We can use the lock
more correctly and to better protect the queue stop and start
operations from cross threading. We can also remove a useless
and expensive bit operation from the Rx path.
This fixes a case found where the link_status_check from a link
flap could run into an MTU change and cause a crash.
