8936419a6c x86: stop unconditionally clearing PSL_T on the trace trap.
We certainly should clear PSL_T when calling the SIGTRAP signal
handler, which is already done by all x86 sendsig(9) ABI code.  On the
other hand, there is no obvious reason why PSL_T needs to be cleared
when returning from the signal handler.  For instance, Linux allows
userspace to set PSL_T and keep tracing enabled for the desired
period.  There are userspace programs which would use PSL_T if we make
it possible, for instance sbcl.

Remember if PSL_T was set by PT_STEP or PT_SETSTEP by mean of TDB_STEP
flag, and only clear it when the flag is set.

3df266dff9 arm64: rockchip: Add proper armclock support
The core clock (armclk) on RockChip SoC is special.
It can derive it's clock from many PLLs but RockChip recommand to do it
from "apll" on old SoC and "npll" on new SoC. The reason for choosing npll
is that it's have less jitter and is more close to the arm core on the SoC.
r333314 added the core clock as a composite clock but due to it's specials
property we need to deal with it differently.
A new rk_clk_armclk type is added for this and it supports only the "npll"
as we don't run on old RockChip SoC that only have the "apll".
It will always reparent to "npll" and set the frequency according to a rate
table that is known to be good.
For now we set the "npll" to the desired frequency and just set the core clk
divider to 1 as its parent it just used for the core clk.

6514b4f061 Add GET_STACK_USAGE() for arm64.
Its absence meant that GEOM direct dispatch was disabled (the service
routines check the current thread's stack usage to determine whether
to hand off the request to a dedicated thread), and this change is
sufficient to enable direct dispatch by default.

According to PR there are cases of controller hang if soft reset is

I don't think this patch is perfect, but it was reported as working
by the submitter, and I have neither the old hardware nor interest to
test some improved version, so just done some style cleaning.

11d416666d Improve MAC address uniqueness on if_epair(4).
As reported in PR184149, it can happen that epair devices can have the same
MAC address.
This solution is based on a 32-bit hash, obtained combining the if_index of
the a interface and the hostid.
If the hostid is zero, a random number is used.

Rework the README to make it a little easier for new users. This is the
first file many will see when persuing the FreeBSD source code so

- remove some of the text describes how to build. This is better covered
in the linked documentation.
- add a small blurb for what FreeBSD is. Some users might find this
document through features such as github search so they may not even
know what the project is

generally, gear this file for the new, accidental, or casual user rather
than towards someone seeking fuller documentation.
