- N32 and N64 do not have a $a0-3 gap.
- Use 'sp += 4' to skip over the gap for O32 rather than '+= i'. It
doesn't make a functional change, but makes the code match the comment.

Create a struct cryptop_data which contains state needed for a single
symmetric crypto operation and move that state out of the session. This
closes a race with the CRYPTO_F_DONE flag that can result in use after
free.
While here, remove the 'cse->error' member. It was just a copy of
'crp->crp_etype' and cryptodev_op() and cryptodev_aead() checked both
'crp->crp_etype' and 'cse->error'. Similarly, do not check for an
error from mtx_sleep() since it is not used with PCATCH or a timeout
so cannot fail with an error.

setup to properly print the numbers as ints. This is the least-gross
way around that, and won't affect the bootloader where we do this.

This adds support for the "fsl,ext-reset-output" FDT property. When
present, that property indicates that a chip reset is accomplished by
asserting the WDOG1_B external signal, which is supposed to trigger some
external component such as a PMIC to ready the hardware for reset (for
example, adjusting voltages from idle to full-power levels), and assert the
POR signal to SoC when ready. To guard against misconfiguation leading to a
non-rebootable system, the external reset signal is backstopped by code
that asserts a normal internal chip reset if nothing responds to the
external reset signal within one second.
in the LinuxKPI. This is done by calling finit() just before returning a magic
value of ENXIO in the "linux_dev_fdopen" function.
The Linux file structure should mimic the BSD file structure as much as
possible. This patch decouples the Linux file structure from the belonging
character device right after the "linux_dev_fdopen" function has returned.
This fixes an issue which allows a Linux file handle to exist after a
character device has been destroyed and removed from the directory index
of /dev. Only when the reference count of the BSD file handle reaches zero,
the Linux file handle is destroyed. This fixes use-after-free issues related
to accessing the Linux file structure after the character device has been
destroyed.
While at it add a missing NULL check for non-present file operation.
Calling a NULL pointer will result in a segmentation fault.

in ffs_sbput(). These functions are exported to libufs via the

virtual address sizes
Summary:
Some architectures use physical addresses larger than virtual. This is the
minimal changeset needed to get CAM/CTL to build on these targets. No
functional changes. More changes would likely be needed for this to be fully
functional on said platforms, but they can be made when needed.

Summary:
Some architectures have physical/bus addresses that are much larger
than virtual addresses. This change just quiets a warning, as DMAP is not used
on those architectures, and on 64-bit platforms uintptr_t is the same size as
vm_paddr_t and void *.

Because there was an extra declaration in the vendor version, we locally
removed the second one in r238405 with 1.0.1c. Later, upstream fixed it in
1.0.2d but they removed the first one. Therefore, both were removed in our
version unfortunately. Now we revert to the vendor one to re-add it.
