Move commonly used pattern of ip6_dst_store() usage to a separate
function - ip6_sk_dst_store_flow(), which will check the addresses
for equality using the flow information, before saving them.
There is no functional changes in this patch. In addition, it will
be used in the next patch, in ip6_sk_dst_lookup_flow().

After commit 581319c586 ("net/socket: use per af lockdep classes for sk queues")
sock queue locks now have per-af lockdep classes, including unix socket.
It is no longer necessary to workaround it.
I noticed this while looking at a syzbot deadlock report, this patch
itself doesn't fix it (this is why I don't add Reported-by).

====================
net: Broadcom drivers sparse fixes
This patch series fixes the same warning reported by sparse in bcmsysport and
bcmgenet in the code that deals with inserting the TX checksum pointers:
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: warning: cast from restricted __be16
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: warning: incorrect type in argument 1 (different base types)
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: expected unsigned short [unsigned] [usertype] val
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: got restricted __be16 [usertype] protocol
This patch fixes both issues by using the same construct and not swapping
skb->protocol but instead the values we are checking against.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
skb->protocol is a __be16 which we would be calling htons() against,
while this is not wrong per-se as it correctly results in swapping the
value on LE hosts, this still upsets sparse. Adopt a similar pattern to
what other drivers do and just assign ip_ver to skb->protocol, and then
use htons() against the different constants such that the compiler can
resolve the values at build time.

Pull namespace updates from Eric Biederman:
"There was a lot of work this cycle fixing bugs that were discovered
after the merge window and getting everything ready where we can
reasonably support fully unprivileged fuse. The bug fixes you already
have and much of the unprivileged fuse work is coming in via other
trees.
Still left for fully unprivileged fuse is figuring out how to cleanly
handle .set_acl and .get_acl in the legacy case, and properly handling
of evm xattrs on unprivileged mounts.
Included in the tree is a cleanup from Alexely that replaced a linked
list with a statically allocated fix sized array for the pid caches,
which simplifies and speeds things up.
Then there is are some cleanups and fixes for the ipc namespace. The
motivation was that in reviewing other code it was discovered that
access ipc objects from different pid namespaces recorded pids in such
a way that when asked the wrong pids were returned. In the worst case
there has been a measured 30% performance impact for sysvipc
semaphores. Other test cases showed no measurable performance impact.
Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc
performance both gave the nod that this is good enough.
Casey Schaufler and James Morris have given their approval to the LSM
side of the changes.
I simplified the types and the code dealing with sysvipc to pass just
kern_ipc_perm for all three types of ipc. Which reduced the header
dependencies throughout the kernel and simplified the lsm code.
Which let me work on the pid fixes without having to worry about
trivial changes causing complete kernel recompiles"

- Lots of work aligning Documentation/ABI with reality, done by Aishwarya
Pant.
- The trace documentation has been converted to RST by Changbin Du
- I thrashed up kernel-doc to deal with a parsing issue and to try to make
the code more readable. It's still a 20+-year-old Perl hack, though.
- Lots of other updates, typo fixes, and more.

This does add an IPMI BMC server-side driver, to allow a Linux
system to act as an IPMI controller. That's the biggest change,
but it is just a new driver that is fairly narrow in use.
The other largish change is removing ACPI SPMI probe support,
which should have never really been there in the beginning.

A quiet release for SPI, some fixes and small updates for individual
drivers with one bigger change from Linus Walleij which coverts the
bitbanging SPI driver to use the GPIO descriptor API from Linus Walleij.
Since GPIO descriptors were used by platform data this means there's a
few changes in arch/ making relevant updates for a few platforms and one
misc driver that are affected.

"These update the ACPICA code in the kernel to follow upstream revision
20180313 which includes fixes related to the so-called module-level
AML (mostly "if" type of statements outside of any methods) that
should improve the handling of systems that load alternative SSDTs
depending on the current configuration, for example, and event
handling fixes related to disabling and enabling GPEs on system
startup and on suspend/resume.
Moreover, the ACPICA license boilerplate is replaced with SPDX license
IDs which alone reduces the number of lines of ACPICA code in the
kernel quite a bit.
Also added is a new driver for the generic ACPI Time and Alarm Device
(TAD). At the moment it only handles the most basic capabilities of
the TAD, however.
In addition to that the ACPI battery driver is improved to handle
battery thresholds on ThinkPads, among other things, some bugs are

Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
"System calls are interaction points between userspace and the kernel.
Therefore, system call functions such as sys_xyzzy() or
compat_sys_xyzzy() should only be called from userspace via the
syscall table, but not from elsewhere in the kernel.
At least on 64-bit x86, it will likely be a hard requirement from
v4.17 onwards to not call system call functions in the kernel: It is
better to use use a different calling convention for system calls
there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
which then hands processing over to the actual syscall function. This
means that only those parameters which are actually needed for a
specific syscall are passed on during syscall entry, instead of
filling in six CPU registers with random user space content all the
time (which may cause serious trouble down the call chain). Those
x86-specific patches will be pushed through the x86 tree in the near
future.
Moreover, rules on how data may be accessed may differ between kernel
data and user data. This is another reason why calling sys_xyzzy() is
generally a bad idea, and -- at most -- acceptable in arch-specific
code.
This patchset removes all in-kernel calls to syscall functions in the
kernel with the exception of arch/. On top of this, it cleans up the
three places where many syscalls are referenced or prototyped, namely
kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

Commit 2a98dc028f ("include/linux/bitmap.h: turn bitmap_set and
bitmap_clear into memset when possible") introduced an optimization to
bitmap_{set,clear}() which uses memset() when the start and length are
constants aligned to a byte.
This is wrong on big-endian systems; our bitmaps are arrays of unsigned
long, so bit n is not at byte n / 8 in memory. This was caught by the
Btrfs selftests, but the bitmap selftests also fail when run on a
big-endian machine.
We can still use memset if the start and length are aligned to an
unsigned long, so do that on big-endian. The same problem applies to
the memcmp in bitmap_equal(), so fix it there, too.
Fixes: 2a98dc028f ("include/linux/bitmap.h: turn bitmap_set and bitmap_clear into memset when possible")
Fixes: 2c6deb0152 ("bitmap: use memcmp optimisation in more situations")

This removes the entire architecture code for blackfin, cris, frv, m32r,
metag, mn10300, score, and tile, including the associated device drivers.
I have been working with the (former) maintainers for each one to ensure
that my interpretation was right and the code is definitely unused in
mainline kernels. Many had fond memories of working on the respective
ports to start with and getting them included in upstream, but also saw
no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company
in charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems
that all the SoC product lines are still around, but have not used the
custom CPU architectures for several years at this point. In contrast,
CPU instruction sets that remain popular and have actively maintained
kernel ports tend to all be used across multiple licensees.
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I made
sure that they are all unused. Some architectures (notably tile, mn10300,
and blackfin) are still being shipped in products with old kernels,
but those products will never be updated to newer kernel releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing their
support or getting it added to mainline gcc in the first place.
They all have patched gcc-7.3 ports that work to some degree, but
complete upstream support won't happen before gcc-8.1. Csky posted
their first kernel patch set last week, their situation will be similar.
