Anup Patel 4e0f9e3a61 RISC-V: Don't mark init section as non-executable ... 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. Further investigating other architectures, it seems marking the init section as non-executable is redundant because the init section pages are anyway poisoned and freed. To fix broken runtime CPU hotplug, we simply remove the code marking the init section as non-executable.
