Split out the insertion of pages to be outside of the alloc->mutex in a separate binder_install_buffer_pages() routine. Since this is no longer serialized, we must look at the full range of pages used by the buffers. The installation is protected with mmap_sem in write mode since multiple tasks might race to install the same page. Besides avoiding unnecessary nested locking this helps in preparation of switching the alloc->mutex into a spinlock_t in subsequent patches.

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 Restructured Text 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.
