Commit 252c765bd764 ("riscv, bpf: Add BPF exception tables") only addressed
RV64, and broke the RV32 build [1]. Fix by gating the exception tables code
with CONFIG_ARCH_RV64I.
Further, silence a "-Wmissing-prototypes" warning [2] in the RV64 BPF JIT.

As I want to test both DEVMAP and DEVMAP_HASH in XDP multicast redirect, I
limited DEVMAP max entries to a small value for performace. When the test
runs after amount of interface creating/deleting tests. The interface index
will exceed the map max entries and xdp_redirect_multi will error out with
"Get interfacesInterface index to large".
Fix this issue by limit the tests in netns and specify the ifindex when
creating interfaces.

Pull SCSI updates from James Bottomley:
"This consists of the usual driver updates (ufs, smartpqi, lpfc,
target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
fixes.
Notable core changes are the removal of scsi->tag which caused some
churn in obsolete drivers and a sweep through all drivers to call
scsi_done() directly instead of scsi->done() which removes a pointer
indirection from the hot path and a move to register core sysfs files
earlier, which means they're available to KOBJ_ADD processing, which
necessitates switching all drivers to using attribute groups"

Pull pin control updates from Linus Walleij:
"The most interesting aspect is that we now have initial support for
the Apple pin controller as used in the M1 laptops and the iPhones
which is a step forward for using Linux efficiently on this Apple
silicon.

- New combined pin control and GPIO driver for the Apple SoC. This is
used in all modern Apple silicon such as the M1 laptops but also in
at least recent iPhone variants.

- New subdriver for the Qualcomm QCM2290
- New subdriver for the Qualcomm PM6350
- New subdriver for the Uniphier NX1

We recently changed bpftool's Makefile to make it install libbpf's
headers locally instead of pulling them from the source directory of the
library. Although bpftool needs two versions of libbpf, a "regular" one
and a "bootstrap" version, we would only install headers for the regular
libbpf build. Given that this build always occurs before the bootstrap
build when building bpftool, this is enough to ensure that the bootstrap
bpftool will have access to the headers exported through the regular
libbpf build.
However, this did not account for the case when we only want the
bootstrap version of bpftool, through the "bootstrap" target. For
example, perf needs the bootstrap version only, to generate BPF
skeletons. In that case, when are the headers installed? For some time,
the issue has been masked, because we had a step (the installation of
headers internal to libbpf) which would depend on the regular build of
libbpf and hence trigger the export of the headers, just for the sake of
creating a directory. But this changed with commit 8b6c46241c77
("bpftool: Remove Makefile dep. on $(LIBBPF) for
$(LIBBPF_INTERNAL_HDRS)"), where we cleaned up that stage and removed
the dependency on the regular libbpf build. As a result, when we only
want the bootstrap bpftool version, the regular libbpf is no longer
built. The bootstrap libbpf version is built, but headers are not
exported, and the bootstrap bpftool build fails because of the missing
headers.
To fix this, we also install the library headers for the bootstrap
version of libbpf, to use them for the bootstrap bpftool and for
generating the skeletons.
Fixes: f012ade10b34 ("bpftool: Install libbpf headers instead of including the dir")

It is generally unsafe to call put_device() with dpm_list_mtx held,
because the given device's release routine may carry out an action
depending on that lock which then may deadlock, so modify the
system-wide suspend and resume of devices to always drop dpm_list_mtx
before calling put_device() (and adjust white space somewhat while
at it).
For instance, this prevents the following splat from showing up in
the kernel log after a system resume in certain configurations:

The ACPI_USE_BUILTIN_STDARG symbol is never set in the kernel build,
so stop checking it in include/acpi/platform/acgcc.h and drop all of
the macros depending on it (which appear to duplicate the analogous
macros from linux/stdarg.h, but in fact are never used).

This file will contain all the definitions we need for SMB2 packets
and will follow the naming convention of MS-SMB2.PDF as closely
as possible to make it easier to cross-reference beween the definitions
and the standard.
The content of this file will mostly consist of migration of existing
definitions in the cifs/smb2.pdu.h and ksmbd/smb2pdu.h files
with some additional tweaks as the two files have diverged.
This patch introduces the new smbfs_common/smb2pdu.h file
and migrates the SMB2 header as well as TREE_CONNECT and TREE_DISCONNECT
to the shared file.

This patch extends the DLN2 driver; adding cell for adc_dln2 module.
The original patch[1] fell through the cracks when the driver was added
so ADC has never actually been usable. That patch did not have ACPI
support which was added in v5.9, so the oldest supported version this
current patch can be backported to is 5.10.
