sctp_inet6addr_event deletes 'addr' from 'local_addr_list' when setting
netdev down, but it is possible to delete the incorrect entry (match
the first one with the same ipaddr, but the different 'ifindex'), if
there are some netdevs with the same 'local-link' ipaddr added already.
It should delete the entry depending on 'sin6_addr' and 'sin6_scope_id'
both. otherwise, the endpoint will call 'sctp_sf_ootb' if it can't find
the according association when receives 'heartbeat', and finally will
reply 'abort'.
For example:
1.when linux startup
the entries in local_addr_list:
ifindex:35 addr:fe80::40:43ff:fe80:0 (eths0.201)
ifindex:36 addr:fe80::40:43ff:fe80:0 (eths0.209)
ifindex:37 addr:fe80::40:43ff:fe80:0 (eths0.210)

Commit 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt
in intel_bios.c") moved the workaround for broken or missing VBT to
intel_bios.c. However is_port_valid() only protects the handling of
different skus of the same display version. Since in
intel_setup_outputs() we share the code path with version 9, this would
also create port F for SKL/KBL, which does not exist.
Missing VBT can be reproduced when starting a headless QEMU with no
opregion available.
Avoid the issue by splitting versions 9 and 10 in intel_setup_outputs(),
which also makes it more clear what code path it's taking for each
version.
v2: move generic display version after Geminilake since that one has
a different set of outputs

We were using GRAPHICS_VER() to handle SKL_DFSM register, which means we
were not handling GLK correctly since that has GRAPHICS_VER == 9, but
DISPLAY_VER == 10. Switch the entire branch to check DISPLAY_VER
which makes it more in line with Bspec.
Even though the Bspec has an exception for RKL in
TGL_DFSM_PIPE_D_DISABLE, we don't have to do anything as the bit has
disable semantic and RKL doesn't have pipe D.

We have a fairly specific alpha binary loader in Linux: running x86
(i386, i486) binaries via the em86 [1] emulator. As noted in the Kconfig
option, the same behavior can be achieved via binfmt_misc, for example,
more nowadays used for running qemu-user.
An example on how to get binfmt_misc running with em86 can be found in
Documentation/admin-guide/binfmt-misc.rst
The defconfig does not have CONFIG_BINFMT_EM86=y set. And doing a
make defconfig && make olddefconfig
results in
# CONFIG_BINFMT_EM86 is not set
... as we don't seem to have any supported Linux distirbution for alpha
anymore, there isn't really any "default" user of that feature anymore.
Searching for "CONFIG_BINFMT_EM86=y" reveals mostly discussions from
around 20 years ago, like [2] describing how to get netscape via em86
running via em86, or [3] discussing that running wine or installing
Win 3.11 through em86 would be a nice feature.
The latest binaries available for em86 are from 2000, version 2.2.1 [4] --
which translates to "unsupported"; further, em86 doesn't even work with
glibc-2.x but only with glibc-2.0 [4, 5]. These are clear signs that
there might not be too many em86 users out there, especially users
relying on modern Linux kernels.
Even though the code footprint is relatively small, let's just get rid
of this blast from the past that's effectively unused.

This issue was noticed while debugging a shutdown issue where some
secondary CPUs are not being shutdown correctly. A fix for that [1] requires
that secondary cpus be offlined using the cpu_online_mask so that the
stop operation is a no-op if CPU HOTPLUG is disabled. I, like the author in
[1] looked at the architectures and found that alpha is one of two
architectures that executes smp_send_stop() on all possible CPUs.
On alpha, smp_send_stop() sends an IPI to all possible CPUs but only needs
to send them to online CPUs.
Send the stop IPI to only the online CPUs.

since 889b3c1245de48ed0cacf7aebb25c489d3e4a3e9, CONFIG_OPTIMIZE_INLINING
is removed entirely and inline is always defined to `inline __gnu_inline
__inline_maybe_unused notrace` in compiler_types.h
Besides, undef inline here also means it never use
__attribute__((__gnu_inline__)), so `extern inline` function can never
be defined header files, otherwise multiple definition errors will
happen, e.g. if multiple translation units use alpha/include/asm/pal.h
will report multiple definitions, because there are many extern inline
function definitions in this header.
``` c
extern inline TYPE NAME(void) \
{ \
register TYPE __r0 __asm__("$0"); \
__asm__ __volatile__( \
...
```
Ofc, it is also ok to remove `extern` in `extern inline` here, then all
of iso c99 and gnuc99/89 are ok, but there are also other alpha headers
have such function definitions.

sctp: improve the pmtu probe in Search Complete state
Timo recently suggested to use the loss of (data) packets as
indication to send pmtu probe for Search Complete state, which
should also be implied by RFC8899. This patchset is to change
the current one that is doing probe with current pmtu all the
time.

This patch is to introduce last_rtx_chunks into sctp_transport to detect
if there's any packet retransmission/loss happened by checking against
asoc's rtx_data_chunks in sctp_transport_pl_send().
If there is, namely, transport->last_rtx_chunks != asoc->rtx_data_chunks,
the pmtu probe will be sent out. Otherwise, increment the pl.raise_count
and return when it's in Search Complete state.
With this patch, if in Search Complete state, which is a long period, it
doesn't need to keep probing the current pmtu unless there's data packet
loss. This will save quite some traffic.
v1->v2:
- add the missing Fixes tag.

This patch does 3 things:
- make sctp_transport_pl_send() and sctp_transport_pl_recv()
return bool type to decide if more probe is needed to send.
- pr_debug() only when probe is really needed to send.
- count pl.raise_count in sctp_transport_pl_send() instead of
sctp_transport_pl_recv(), and it's only incremented for the
1st probe for the same size.
These are preparations for the next patch to make probes happen
only when there's packet loss in Search Complete state.

gcc doesn't care, but clang quite reasonably pointed out that the recent
commit e9ba16e68cce ("smpboot: Mark idle_init() as __always_inlined to
work around aggressive compiler un-inlining") did some really odd
things:
kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier]
static inline void __always_inline idle_init(unsigned int cpu)
^
which not only has that duplicate inlining specifier, but the new
__always_inline was put in the wrong place of the function definition.
We put the storage class specifiers (ie things like "static" and
"extern") first, and the type information after that. And while the
compiler may not care, we put the inline specifier before the types.
So it should be just
static __always_inline void idle_init(unsigned int cpu)
instead.

In the existing code while changing the number of TX/RX
queues using ethtool the PF/VF interface resources are
freed and reallocated (otx2_stop and otx2_open is called)
if the device is in running state. If any resource allocation
fails in otx2_open, driver free already allocated resources
and return. But again, when the number of queues changes
as the device state still running oxt2_stop is called.
In which we try to free already freed resources leading
to driver crash.
This patch fixes the issue by setting the INTF_DOWN flag on
error and free the resources in otx2_stop only if the flag is
not set.

Currently PKINDs are not assigned to LBK channels.
The default value of LBK_CHX_PKIND (channel to PKIND mapping) register
is zero, which is resulting in a overlap of pkind between LBK and CGX
LMACs. When KPU1 parser config is modified when PTP timestamping is
enabled on the CGX LMAC interface it is impacting traffic on LBK
interfaces as well.
This patch fixes the issue by reserving the PKIND#0 for LBK devices.
CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

Pull RISC-V fixes from Palmer Dabbelt:
- properly set the memory size, which fixes 32-bit systems
- allow initrd to load anywhere in memory, rather that restricting it
to the first 256MiB
- fix the 'mem=' parameter on 64-bit systems to properly account for
the maximum supported memory now that the kernel is outside the
linear map
- avoid installing mappings into the last 4KiB of memory, which
conflicts with error values
- avoid the stack from being freed while it is being walked
- a handful of fixes to the new copy to/from user routines
* tag 'riscv-for-linus-5.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:

Commit 71f642833284 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer
that was possibly NULL. That fails miserably, because that helper
inline function is not set up to handle that case.
Just make acpi_dev_put() silently accept a NULL pointer, rather than
calling down to put_device() with an invalid offset off that NULL
pointer.
