Subject[PATCH 0/6] Fixes for memory corruption in mpt2sas
Hello all,

This patchset attempts to address problems we've been having with
panics due to memory corruption from the mpt2sas driver.

I will provide a similar set of fixes for mpt3sas, since we see
similar issues there as well. "Porting" this to mpt3sas will be
trivial since the part of the driver I'm touching is nearly identical
between the two, so I thought it would be simpler to review a patch
against mpt2sas alone at first.

I've tested this for a few days on a big storage box that seemed to be
very susceptible to the panics, and so far it seems to have eliminated
