User space verbs provider library would need chip context. Changing the
ABI to add chip version details in structure. Furthermore, changing the
kernel driver ucontext allocation code to initialize the abi structure
with appropriate values.
As suggested by community, appended the new fields at the bottom of the
ABI structure and retaining to older fields as those were in the older
versions.
Keeping the ABI version at 1 and adding a new field in the ucontext
response structure to hold the component mask. The user space library
should check pre-defined flags to figure out if a certain feature is
supported on not.

Netlink statistics exported by rdma-cm never had any working user space
component published to the mailing list or to any open source
project. Canvassing various proprietary users, and the original requester,
we find that there are no real users of this interface.
This patch simply removes all occurrences of RDMA CM netlink in favour of
modern nldev implementation, which provides the same information and
accompanied by widely used user space component.

A soft iwarp driver that uses the host TCP stack via a kernel mode socket
does not need port mapping. In fact, if the port map daemon, iwpmd, is
running, then iwpmd must not try and create/bind a socket to the actual
port for a soft iwarp connection, since the driver already has that socket
bound.
Yet if the soft iwarp driver wants to interoperate with hard iwarp devices
that -are- using port mapping, then the soft iwarp driver's mappings still
need to be maintained and advertised by the iwpm protocol.
This patch enhances the rdma driver<->iwcm interface to allow an iwarp
driver to specify that it does not want port mapping. The iwpm
kernel<->iwpmd interface is also enhanced to pass up this information on
map requests.
Care is taken to interoperate with the current iwpmd version (ABI version
3) and only use the new NL attributes if iwpmd supports ABI version 4.
The ABI version define has also been created in rdma_netlink.h so both
kernel and user code can share it. The iwcm and iwpmd negotiate the ABI
version to use with a new HELLO netlink message.

In order to add new IWPM_NL attributes, the enums for the IWPM commands
attributes are refactored such that a new attribute can be added without
breaking ABI version 3. Instead of sharing nl attribute enums for both
request and response messages, we create separate enums for each IWPM
message request and reply. This allows us to extend any given IWPM
message by adding new attributes for just that message. These new enums
are created, though, in a way to avoid breaking ABI version 3.

Merge tag 'v4.20' into for-linus
Sync with mainline to get linux/overflow.h among other things.
The usec part of the timeval is defined as
__kernel_suseconds_t tv_usec; /* microseconds */
Arnd noticed that sparc64 is the only architecture that defines
__kernel_suseconds_t as int rather than long.
This breaks the current y2038 fix for kernel as we only access and define
the timeval struct for non-kernel use cases. But, this was hidden by an
another typo in the use of __KERNEL__ qualifier.
Fix the typo, and provide an override for sparc64.

This is sort of a mix between a new feature and a bug fix. I've managed
to screw up merging this patch set a handful of times but I think it's
OK this time around. The main new feature here is audit support for
RISC-V, with some fixes to audit-related bugs that cropped up along the
way:
* The addition of NR_syscalls into unistd.h, which is necessary for
CONFIG_FTRACE_SYSCALLS.
* The definition of CREATE_TRACE_POINTS so
__tracepoint_sys_{enter,exit} get defined.
* A fix for trace_sys_exit() so we can enable
CONFIG_HAVE_SYSCALL_TRACEPOINTS.
On RISC-V (riscv) audit is supported through generic lib/audit.c.
The patch adds required arch specific definitions.

"Add Adiantum support for fscrypt"
* tag 'fscrypt_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/fscrypt:
fscrypt: add Adiantum support
Add support for the Adiantum encryption mode to fscrypt. Adiantum is a
tweakable, length-preserving encryption mode with security provably
reducible to that of XChaCha12 and AES-256, subject to a security bound.
It's also a true wide-block mode, unlike XTS. See the paper
"Adiantum: length-preserving encryption for entry-level processors"
(https://eprint.iacr.org/2018/720.pdf) for more details. Also see
commit 059c2a4d8e ("crypto: adiantum - add Adiantum support").
On sufficiently long messages, Adiantum's bottlenecks are XChaCha12 and
the NH hash function. These algorithms are fast even on processors
without dedicated crypto instructions. Adiantum makes it feasible to
enable storage encryption on low-end mobile devices that lack AES
instructions; currently such devices are unencrypted. On ARM Cortex-A7,
on 4096-byte messages Adiantum encryption is about 4 times faster than
AES-256-XTS encryption; decryption is about 5 times faster.
In fscrypt, Adiantum is suitable for encrypting both file contents and
names. With filenames, it fixes a known weakness: when two filenames in
a directory share a common prefix of >= 16 bytes, with CTS-CBC their
encrypted filenames share a common prefix too, leaking information.
Adiantum does not have this problem.
Since Adiantum also accepts long tweaks (IVs), it's also safe to use the
master key directly for Adiantum encryption rather than deriving
per-file keys, provided that the per-file nonce is included in the IVs
and the master key isn't used for any other encryption mode. This
configuration saves memory and improves performance. A new fscrypt
policy flag is added to allow users to opt-in to this configuration.

MAX_FAT is useless in msdos_fs.h, since it uses the MSDOS_SB function
that is defined in fat.h. So really, this macro can be only called from
code that already includes fat.h.
Hence, this patch moves it to fat.h, right after MSDOS_SB is defined. I
also changed it to an inline function in order to save the double call
to MSDOS_SB. This was suggested by joe@perches.com in the previous
version.
This patch is required for the next in the series, in which the variant
(whether this is FAT12, FAT16 or FAT32) checks are replaced with new
macros.

Since the FAT_FIRST_ENT macro checks the FAT variant in a way that the

explanation of what was checked.
I verified that the changed comment is correct according to Microsoft
FAT spec, search for "BPB_Media" in the following references:
1. Microsoft FAT specification 2005
(http://read.pudn.com/downloads77/ebook/294884/FAT32%20Spec%20%28SDA%20Contribution%29.pdf).
Search for 'volume label'.
2. Microsoft Extensible Firmware Initiative, FAT32 File System Specification

Search for 'volume label'.

The FAT file system volume label file stored in the root directory
should match the volume label field in the FAT boot sector. As
consequence, the max length of these fields ought to be the same. This
patch replaces the magic '11' usef in the struct fat_boot_sector with
MSDOS_NAME, which is used in struct msdos_dir_entry.

3. User space code that creates FAT filesystem
sometimes uses MSDOS_NAME for the label, sometimes not.
Search for 'if (memcmp(label, NO_NAME, MSDOS_NAME))'.
I consider to make the same patch there as well.

Commit 092a53452b ("autofs: take more care to not update last_used on
path walk") helped to (partially) resolve a problem where automounts
were not expiring due to aggressive accesses from user space.
This patch was later reverted because, for very large environments, it
meant more mount requests from clients and when there are a lot of
clients this caused a fairly significant increase in server load.
But there is a need for both types of expire check, depending on use
case, so add a mount option to allow for strict update of last use of
autofs dentrys (which just means not updating the last use on path walk
access).
