1526237bc6 x86 memory: use page_offset_base from linux 
rhel 7.5 and later kernels have a page offset that is no longer
necessarily 0xffff880000000000, leading to kernel panics if we

a563d780c1 munmap: fix deadlock with remote pagefault on vm range lock 
Add similar protection to clear_host_pte than to set_host_vma (see #986)

Also make the page fault handler only skip taking lock if the munmap
happened on the same cpu id

edd3ea0103 Revert "memory_range_lock: Enable interrupt when trylock fails" 
This reverts commit 0d3ef65092.

Reason for revert: This fix causes circular dependency with memory_range manipulation and TLB flush. See #1394.

ba80dd8650 arm64: Fix for ptrace instruction rewrite on thunder-x2. 
- Fixed the problem that instruction rewriting by PTRACE_POKETEXT is not reflected.
   The cause is that the instruction cache was not flushed.

 - Add instruction chache flush in ptrace_report_signal().

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)
