Matthew Wilcox 5ade60dda4 ida: Add new API
Add ida_alloc(), ida_alloc_min(), ida_alloc_max(), ida_alloc_range()
and ida_free().  The ida_alloc_max() and ida_alloc_range() functions
differ from ida_simple_get() in that they take an inclusive 'max'
parameter instead of an exclusive 'end' parameter.  Callers are about
evenly split whether they'd like inclusive or exclusive parameters and
'max' is easier to document than 'end'.

Change the IDA allocation to first attempt to allocate a bit using
existing memory, and only allocate memory afterwards.  Also change the
behaviour of 'min' > INT_MAX from being a BUG() to returning -ENOSPC.

Leave compatibility wrappers in place for ida_simple_get() and
ida_simple_remove() to avoid changing all callers.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
