Brian Behlendorf 744038069d Merge branch 'builtin-clean' 
Support in-tree builtin module building.

These commits add support for compiling the SPL module as a built-in
kernel module by copying the module code into the kernel source tree.
Here's the procedure:

  - Create your kernel configuration (`.config` file) as usual. This
    has to be done first so that SPL's configure script is able to
    detect kernel features correctly.
  - Run `make prepare scripts` inside the kernel source tree.
  - Run `./configure --enable-linux-builtin --with-linux=/usr/src/linux-...`
    inside the SPL directory.
  - Run `./copy-builtin /usr/src/linux-...` inside the SPL directory.
  - In the kernel source tree, enable the `CONFIG_SPL` option
    (e.g. using `make menuconfig`).
  - Build the kernel as usual.

SPL module parameters can be set at boot time using the following syntax
on the kernel command line: `spl.parameter_name=parameter_value`.

README.markdown

The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.

To build packages for your distribution:

$ ./configure
$ make pkg

To copy the kernel code inside your kernel source tree for builtin compilation:

$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...

Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
