1b6df69309 raid6test: fix stack overflow
Testing on x86_64 with NDISKS=255 yields:

   do_IRQ: modprobe near stack overflow (cur:ffff88007d19c000,sp:ffff88007d19c128)

...and eventually

   general protection fault: 0000 [#1]

Moving the scribble buffers off the stack allows the test to complete
successfully.

cb3c82992f async_tx: raid6 recovery self test
Port drivers/md/raid6test/test.c to use the async raid6 recovery
routines.  This is meant as a unit test for raid6 acceleration drivers.  In
addition to the 16-drive test case this implements tests for the 4-disk and
5-disk special cases (dma devices can not generically handle less than 2
sources), and adds a test for the D+Q case.
