dfb3bef96d irqbalance_mck: replace extra service with service drop-in
Using a drop-in instead of an extra service avoids having to juggle
between both services (especially since irqbalance_mck did not have a
Conflict=irqbalance.service statement)

That way, we only have a single service to check for (irqbalance.service),
and system administrators should find this less confusing if they normally
rely on irqbalance.

The drop-in is also installed in /run so will automatically disappear in
the event of a linux crash or a reboot without shutting down mckernel

791e8c2114 Remove mcoverlayfs code
mcoverlayfs code is now unused (technically should work on top of the
soft emulation but not well tested, and untested unused code is bad).
Remove it.

Left the unshare/bind_mount_recursive code in mcexec in a new
MCEXEC_BIND_MOUNT ifdef (only in config.h.in directly to discourage use.
it disables the ioctl as well, but the main code is still compiled to
keep up to date with linux api changes... although it's using kallsyms
lookup so it does not validate much more than "the symbol still exists")

I honestly think this should go as well (people who would want to use it
are root and could do it manually), but will give up for now.

c96dfb0c68 mcstop: add -k to kill processses using /dev/mcos* before shutdown
Use lsof to check for processes that still open /dev/mcosX at shutdown
time.
If lsof is not installed then the check is just not done (empty PROCS
result)

If -k is not passed, print a message listing pids of users and exit
(taking bets someone will use that and sed to kill out of mcstop+release
and rerun the stop script instead of passing -k at some point)

Since arm64 shares the return value with the area of

the system call execution completes destroys the first argument.

10cca81401 arm64 vdso warning: fix non-void function not returning
arch_setup_vdso() needs to return something even on panic to please gcc.
In theory, flagging panic() with __attribute__((noreturn)) should work
just the same and is a much better solution but for some reason on older
gcc versions setting the flag leads to the weak memset() symbol not
being found !?
