1.For coherent DMA
In swiotlb_alloc_coherent, it directly return vaddr on success, and
pass vaddr to free_pages on failure. So, we can directly transparent pass
vaddr from __dma_free to swiotlb_free_coherent.
According to my testing, it can save 8 clock cycles.

Drop field int_queue from tpm_vendor_specific as it is used only by

what about a "normal" case, when things are not going to explode printk(),
but we have several lockups on the same lock (which is probably more
likely than printk recursion)?

Hi,
Interests[1] have been shown in multipage bvecs, so this patchset
try to prepare for the support and do two things:
1) the 1st 4 patches use bvec iterator to implement iterate_bvec(),
then we can drop the non-standard way for iterating bvec
2) remove BIO_MAX_SECTORS & BIO_MAX_SIZE, and now t
bvec has provided one iterator already, so not necessary
to invent a new wheel for this job.

bvec iterator helpers should be used to implement by
iterate_bvec():lib/iov_iter.c too, and move them into
one header, so that we can keep bvec iterator header
out of CONFIG_BLOCK. Then we can remove the inventing
of wheel in iterate_bvec().

bvec_iter_advance() only writes the parameter of iterator,
so the base address of bvec can be marked as const safely.
Without the change, we can see compiling warning in the
following patch for implementing iterate_bvec(): lib/iov_iter.c
with bvec iterator.

BIO_MAX_PAGES is used as maximum count of bvecs, so
replace BIO_MAX_SECTORS with BIO_MAX_PAGES since
BIO_MAX_SECTORS is to be removed.

No one need this macro, so remove it. The motivation is
for supporting multipage bvecs, in which we only know
what the max count of bvecs is supported in the bio,
instead of max size or max sectors.

Virtio 1.0 spec allows driver to modify queue size to reduce momery
requeirments. So the driver should write back the queue size actually
allocated, instead of the original value read from the common config
for the queue.
