Hi Tomasz
A few things inline. Includes the alignment issue on
x86_32 that I fell into whilst trying to fix timestamp
alignment issues.
The head text section (i.e. _start, secondary_start_sbi, etc) and the
init section fall under same page table level-1 mapping.
Currently, the runtime CPU hotplug is broken because we are marking
init section as non-executable which in-turn marks head text section
as non-executable.
