A 5.7 kernel hangs during a tcrypt test of padata that waits for an AEAD
request to finish. This is only seen on large machines running many
concurrent requests.
The issue is that padata never serializes the request. The removal of
the reorder_objects atomic missed that the memory barrier in
'seq_buf' provides a very useful abstraction for writing to a string
buffer without needing to worry about it over-flowing. However even
though the API has been stable for couple of years now its still not
exported to kernel loadable modules limiting its usage.
Hence this patch proposes update to

This is prep work for initial support of bonding hardware encryption
pass-through support. The bonding driver will fill in the slave_dev
pointer, and we use that to know not to skb_push() again on a given
skb that was already processed on the bond device.

Slave devices in a bond doing hardware encryption also need to be aware
that they're slaves, so we operate on the slave instead of the bonding
master to do the actual hardware encryption offload bits.

I've been unable to get my hands on suitable supported hardware to date,
but I believe this ought to be all that is needed to enable the mlx5
driver to also work with bonding active-backup crypto offload passthru.

Currently, this support is limited to active-backup mode, as I'm not sure
about the feasilibity of mapping an xfrm_state's offload handle to
multiple hardware devices simultaneously, and we rely on being able to
pass some hints to both the xfrm and NIC driver about whether or not
they're operating
This is an initial functional implementation for doing pass-through of
hardware encryption from bonding device to capable slaves, in active-backup
bond setups. This was developed and tested using ixgbe-driven Intel x520
interfaces with libreswan and a transport mode connection, primarily using

Allow the compat vdso (32b) to be compiled as either THUMB2 (default) or
ARM.
For THUMB2, the register r7 is reserved for the frame pointer, but
code in arch/arm64/include/asm/vdso/compat_gettimeofday.h
uses r7. Explicitly set -fomit-frame-pointer, since unwinding through

Add all FIFO parsing and reading functions. Add accel and gyro
kfifo buffer and FIFO data parsing. Use device interrupt for
reading data FIFO and launching accel and gyro parsing.
Support hwfifo watermark by multiplexing gyro and accel settings.
Support hwfifo flush.
