The value of the revision is stored in musb->tusb_revision,
so don't re-read it every time.
Exporting tusb_get_revision is not needed anymore,
so the dependency loop between tusb6010 and tusb6010_omap is resolved.

The following happens when trying to run a kvm guest on a kernel

In arch/arm/kvm/mmu.c:unmap_range(), we end up doing an extra put_page()
on the stage2 pgd which leads to the BUG in put_page_testzero(). This
happens because a pud_huge() test in unmap_range() returns true when it
should always be false with 2-level pages tables used by 64k pages.
This patch removes support for huge puds if 2-level pagetables are
being used.

Add a defconfig for mach-qcom platforms (copied from msm_defconfig).

When there isn't enough vring descriptor for adding to vq,
blk-mq will be put as stopped state until some of pending
descriptors are completed & freed.
Unfortunately, the vq's interrupt may come just before
blk-mq's BLK_MQ_S_STOPPED flag is set, so the blk-mq will
still be kept as stopped even though lots of descriptors
are completed and freed in the interrupt handler. The worst
case is that all pending descriptors are freed in the
interrupt handler, and the queue is kept as stopped forever.
This patch fixes the problem by starting/stopping blk-mq
with holding vq_lock.

CS0 at 0x80000000
CS1 at 0x90000000
Each bank is connected to 128MB of DRAM, giving a total of 256MB of system DRAM.
