arm64: mm: drop VM_FAULT_BADMAP/VM_FAULT_BADACCESS
Patch series "mm: remove arch's private VM_FAULT_BADMAP/BADACCESS", v2.
Directly set SEGV_MAPRR or SEGV_ACCERR for arm/arm64 to remove the last
two arch's private vm_fault reasons.
This patch (of 2):
If bad map or access, directly set si_code to SEGV_MAPRR or SEGV_ACCERR,
also set fault to 0 and goto error handling, which make us to drop the
arch's special vm fault reason.
