2011-09-30staging: nvec: Have nvec_write_async() return -ENOMEM on OOMJulian Andres Klode
Change nvec_write_async() to return an integer, 0 by default, a negative error on failure. Change nvec_write_sync() to check the return value and abort if it is negative.

2011-09-30staging: nvec: Rewrite the interrupt handlerJulian Andres Klode
Rewrite the interrupt handler to use a state machine similar to that found in the various kernels for the Advent Vega. This also changes the code to use the new functions introduced in the previous commits. This also merges the rewrite sent in August 2011 by Marc Dietrich, and thus also includes code by him. His original patch can be found on the mailing list.
