[PATCH][_COMPAT_H] git://linuxtv.org/media_build.git Legacy issues

[Malcolm Priestley <tvboxspy@gmail.com>]

Clean up legacy issues for error free build on Kernel 2.6.37.

Today while testing on Kernel 2.6.35 latest tarball throws error with 
alloc_ordered_workqueue undefined on Kernels less than 2.6.37. defined back to 
create_singlethread_workqueue.

Please test on other kernel versions.

Tested-on 2.6.35/37 by: Malcolm Priestley <tvboxspy@gmail.com>
