9f1e6d707c get_mempolicy: Support (MPOL_F_NODE | MPOL_F_ADDR) specified 
If flags specifies both MPOL_F_NODE and MPOL_F_ADDR,

which the address addr is allocated into the location pointed to by mode.

fe08ac4a67 arm: turn off cpu on panic 
Since interrupts are disabled on panic, linux cannot reset a
panic'd core when NMI are disabled (for e.g. mcreboot/mcstop)

Just always offline it, so linux can get it back

4d215de641 Separate mmap area from program loading (relocation) area 
We need to separate the two because the heap of a PIE is created in
the area to which it is mapped.

Related commits:

b1309a5d: PIE is mapped at map_end instead of at
          user_start
c4219655: Interpreter is mapped to map_start to make a
          system call that dereferences a NULL pointer fail

9bf225d193 mckernel overlay: replace mcoverlayfs with a soft userspace overlay 
mcoverlayfs has a high maintenance burden and does not work on rhel8's 4.18
kernel (while it works on vanilla 4.18...); instead of debugging this further
time is better spent making it independent from overlayfs.
