Brian Behlendorf 9b51f21841 Remove TQ_SLEEP -> KM_SLEEP mapping 
When the taskq code was originally written it seemed like a good
idea to simply map TQ_SLEEP to KM_SLEEP.  Unfortunately, this
assumed that the TQ_* flags would never confict with any of the
Linux GFP_* flags.  When adding the TQ_PUSHPAGE support in commit
cd5ca4b this invariant was accidentally broken.

Therefore to support TQ_PUSHPAGE, which is needed for Linux, and
prevent any further confusion I have removed this direct mapping.
The TQ_SLEEP, TQ_NOSLEEP, and TQ_PUSHPAGE are no longer defined
in terms of their KM_* counterparts.  Instead a simple mapping
function is introduce to convert TQ_* -> KM_* where needed.

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
