Shared buffer allocation is usually done in cell increments.
Drivers will either round up the allocation or refuse the
configuration if it's not an exact multiple of cell size.
Drivers know exactly the cell size of shared buffer, so help

net: y2038-safe socket timestamps
The series introduces new socket timestamps that are
y2038 safe.
The time data types used for the existing socket timestamp
options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING
are not y2038 safe. The series introduces SO_TIMESTAMP_NEW,
SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these.
These new timestamps can be used on all architectures.
The alternative considered was to extend the sys_setsockopt()
by using the flags. We did not receive any strong opinions about
either of the approaches. Hence, this was chosen, as glibc folks
preferred this.
The series does not deal with updating the internal kernel socket
calls like rxrpc to make them y2038 safe. This will be dealt
with separately.
Note that the timestamps behavior already does not match the
man page specific behavior:
SIOCGSTAMP
This ioctl should only be used if the socket option SO_TIMESTAMP
is not set on the socket. Otherwise, it returns the timestamp of
the last packet that was received while SO_TIMESTAMP was not set,
or it fails if no such packet has been received,
(i.e., ioctl(2) returns -1 with errno set to ENOENT).
The recommendation is to update the man page to remove the above statement.
The overview of the socket timestamp series is as below:
1. Delete asm specific socket.h when possible.
2. Support SO/SCM_TIMESTAMP* options only in userspace.
3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD.
3. Alter socket options so that SOCK_RCVTSTAMPNS does
not rely on SOCK_RCVTSTAMP.
4. Introduce y2038 safe types for socket timestamp.
5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW.
6. Intorduce new y2038 safe socket timeout options.
Changes since v4:
* Fixed the typo in calling sock_get_timeout()
Changes since v3:
* Rebased onto net-next and fixups as per review comments
* Merged the socket timeout series
* Integrated Arnd's patch to simplify compat handling of timeout syscalls
Changes since v2:
* Removed extra functions to reduce diff churn as per code review
Changes since v1:
* Dropped the change to disentangle sock flags
* Renamed sock_timeval to __kernel_sock_timeval
* Updated a few comments
* Added documentation changes
====================

SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval
as the time format. struct timeval is not y2038 safe.
The subsequent patches in the series add support for new socket
timeout options with _NEW suffix that will use y2038 safe
data structures. Although the existing struct timeval layout
is sufficiently wide to represent timeouts, because of the way
libc will interpret time_t based on user defined flag, these
new flags provide a way of having a structure that is the same
for all architectures consistently.
Rename the existing options with _OLD suffix forms so that the
right option is enabled for userspace applications according
to the architecture and time_t definition of libc.

The new type is meant to be used as a y2038 safe structure
to be used as part of cmsg data.
Presently the SO_TIMESTAMP socket option uses struct timeval
for timestamps. This is not y2038 safe.
Subsequent patches in the series add new y2038 safe socket
option to be used in the place of SO_TIMESTAMP_OLD.
struct __kernel_sock_timeval will be used as the timestamp
format at that time.
struct __kernel_sock_timeval also maintains the same layout
across 32 bit and 64 bit ABIs.

As part of y2038 solution, all internal uses of
struct timeval are replaced by struct __kernel_old_timeval
and struct compat_timeval by struct old_timeval32.
Make socket timestamps use these new types.
This is mainly to be able to verify that the kernel build

This is a cleanup to prepare for the addition of 64-bit time_t
in O_SNDTIMEO/O_RCVTIMEO. The existing compat handler seems
unnecessarily complex and error-prone, moving it all into the
main setsockopt()/getsockopt() implementation requires half
as much code and is easier to extend.
32-bit user space can now use old_timeval32 on both 32-bit
and 64-bit machines, while 64-bit code can use
__old_kernel_timeval.

To be able to use the paged version of e.g. phy_write() we need a

Shifts by zero do nothing, and should be treated as nops.
Even though compiler is not supposed to generate such instructions and
manual written assembly is unlikely to have them, but they are legal
instructions and have defined behavior.
This patch correct existing shifts code-gen to make sure they do nothing
when shift amount is zero except when the instruction is ALU32 for which
high bits need to be cleared.
For shift amount bigger than type size, already, NFP JIT back-end errors
out for immediate shift and only low 5 bits will be taken into account for
indirect shift which is the same as x86.

devlink: add device (driver) information API
fw_version field in ethtool -i does not suit modern needs with 31
characters being quite limiting on more complex systems. There is
also no distinction between the running and flashed versions of
the firmware.
Since the driver information pertains to the entire device, rather
than a particular netdev, it seems wise to move it do devlink, at
the same time fixing the aforementioned issues.
The new API allows exposing the device serial number and versions
of the components of the card - both hardware, firmware (running
and flashed). Driver authors can choose descriptive identifiers
for the version fields. A few version identifiers which seemed
relevant for most devices have been added to the global devlink
header.
Example:
$ devlink dev info pci/0000:05:00.0
pci/0000:05:00.0:
driver nfp
serial_number 16240145
versions:
fixed:
board.id AMDA0099-0001
board.rev 07
board.vendor SMA
board.model carbon
running:
fw.mgmt: 010156.010156.010156
fw.cpld: 0x44
fw.app: sriov-2.1.16
stored:
fw.mgmt: 010158.010158.010158
fw.cpld: 0x44
fw.app: sriov-2.1.20
Last patch also includes a compat code for ethtool. If driver
reports no fw_version via the traditional ethtool API, ethtool
can call into devlink and try to cram as many versions as possible
into the 31 characters.
v4:
- use IS_REACHABLE instead of IS_ENABLED in last patch.
v3 (Jiri):
- rename various functions and attributes;
- break out the version helpers per-type;
- make the compat code parse a dump instead of special casing
in each helper;
- move generic version defines to a separate patch.
v2:
- rebase.
this non-RFC, v3 some would say:
- add three more versions in the NFP patches;
- add last patch (ethool compat) - Andrew & Michal.
RFCv2:
- use one driver op;
- allow longer serial number;
- wrap the skb into an opaque request struct;
- add some common identifier into the devlink header.

Signed-off-by: David S. Miller <davem@davemloft.net>
If driver did not fill the fw_version field, try to call into
the new devlink get_info op and collect the versions that way.
We assume ethtool was always reporting running versions.
v4:
- use IS_REACHABLE() to avoid problems with DEVLINK=m (kbuildbot).
v3 (Jiri):
- do a dump and then parse it instead of special handling;
- concatenate all versions (well, all that fit :)).
