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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
