Dear Marek,
After applying these 4 patches I don't see any alignment spew and it
detects the
mass storage device perfectly though I see a warning "EHCI timed out on
TD - token=0x80008c80"
consistently in each "usb reset".
Thanx & Regards,
Puneet

Puneet, can you please test this stuff? It should fix your cache misalignment
issues. Mine are now gone and USB works with caches on too.
I'd like to queue this for -next.
Best regards,
Marek Vasut
