A resend of the one-line patch to fix a regression that did not make it in ...

Juan was kind enough to linger on site, and work on a production machine, to try the parameter to make the system stable. He discovered that reducing the maximum transfer size issued to the adapter to 128KB stabilized his system. This is related to an earlier change for the 2.6.13 tree resulting from Martin Drab's testing where the transfer size was reduced from 4G to 256KB; we needed to go still further in scaling back the request size.

Here is the patch that tames this regression.

Applies to the tree.

Subject: Linux v2.6.14-rc4

Here's the final -rc before a 2.6.14 release.

In the diffstat, most of the changes are one-liners, with the main
exceptions being some sparc64 work (fix user-space corruption due to FP
save/restore) and the new Megaraid SAS driver. There's some networking
fixes, and a couple of driver updates (scsi: aacraid, net: cassini, and
watchdog: pcwd_pci).

Along with a x86-64 suspend/resume page table corruption and some new
defconfig files for ARM, that rounds out the bigger chunks.

The shortlog (appended) should be a pretty good idea of the rest.
