Use the date of the last commit from gj@ (d276a4dfa6f5f3711808eff44ff20a92114b4d6e)
Note that for other developers the date is that when the commit bit was taken

Currently, sysctls which enable KDB in some way are flagged with
CTLFLAG_SECURE, meaning that you can't modify them if securelevel > 0.
This is so that KDB cannot be used to lower a running system's
securelevel, see commit 3d7618d8bf. However, the newer mac_ddb(4)
restricts DDB operations which could be abused to lower securelevel
while retaining some ability to gather useful debugging information.
To enable the use of KDB (specifically, DDB) on systems with a raised
securelevel, change the KDB sysctl policy: rather than relying on
CTLFLAG_SECURE, add a check of the current securelevel to kdb_trap().
If the securelevel is raised, only pass control to the backend if MAC
specifically grants access; otherwise simply check to see if mac_ddb
vetoes the request, as before.
Add a new secure sysctl, debug.kdb.enter_securelevel, to override this
behaviour. That is, the sysctl lets one enter a KDB backend even with a
raised securelevel, so long as it is set before the securelevel is
raised.

Summary:
This review ports mlx5 driver, kernel's OFED stack (userland is already enabled), KTLS and krping to powerpc64 and powerpc64le.
krping requires a small change since it uses assembly for amd64 / i386.
NOTE: On powerpc64le RDMA works fine in the userspace with libmlx5, but on powerpc64 it does not. The problem is that contrib/ofed/libmlx5/doorbell.h checks for SIZEOF_LONG but this macro exists on neither powerpc64* nor amd64. Thus, the file silently goes to the fallback function written for 32-bit architectures. It works fine on little-endian architectures, but causes a hard fail on big-endian. It's possible it may also cause some runtime issues on little-endian.
Thus, on powerpc64 I verified that RDMA works with krping.

The motivation is that some platforms may not be able do anything
meaningful via cpu_reset(), due to a lack of standardized reset
mechanism and/or firmware shortcomings. However, they may have a
separate device driver attached that normally performs the reboot. Such
is the case for some versions of the Raspberry Pi, where reset via PSCI
