Directly set SEGV_MAPRR or SEGV_ACCERR for arm/arm64 to remove the last
two arch's private vm_fault reasons.

v2:
- fix unbalanced mmap lock and set si_code to SEGV_MAPERR by default
  before error handling, which also fix ltp fail reported by Aishwarya

Kefeng Wang (2):
  arm64: mm: drop VM_FAULT_BADMAP/VM_FAULT_BADACCESS
  arm: mm: drop VM_FAULT_BADMAP/VM_FAULT_BADACCESS
