a9973e913d uti: futex call function in mcctrl 
Previously, futex code of McKerenl was called by mccontrol,
but there ware some problems with this method.
(Mainly, location of McKernel image on memory)

Call futex code in mcctrl instead of the one in McKernel image,
giving the following benefits:
1. Not relying on shared kernel virtual address space with Linux any more
2. The cpu id store / retrieve is not needed and resulting in the code

9f1e6d707c get_mempolicy: Support (MPOL_F_NODE | MPOL_F_ADDR) specified 
If flags specifies both MPOL_F_NODE and MPOL_F_ADDR,
get_mempolicy() will return the node ID of the node on
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

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.
