The megaraid_sas HBA only has a single register for I/O submission,
which will be hit pretty hard with scsi-mq. To ensure that the
PCI writes have made it across we need to add a mmio barrier
after each write; otherwise I've been seeing spurious command
completions and I/O stalls.

Hi all,
here's the patcheset to enable scsi-mq support for megaraid_sas.

This patch enables full scsi multiqueue support. But as I have

Hi,
This patchset cleans up direct access to bvec table.
The 1st patch passes bvec table to bio_init(), so that
direct access to bvec table in bio initialization is avoided.
For other patches, most of them uses bio_add_page()
to replace hardcode style of adding page to bvec,
and others avoids to
When the bio is full, bio_add_pc_page() will return zero,
so use this way to handle full bio.
Also replace access to .bi_vcnt for pr_debug() with bio_segments().

This patch enables full scsi-mq support for the hpsa driver.
Due to some reports of performance regressions this patch
also adds a parameter 'use_blk_mq' which can be used to
disable multiqueue support if required.

Hello James and Martin,
This short patch series fixes a deadlock that I ran into for the first
time several months ago but for which I had not yet had the time to post
a fix. As usual, feedback is appreciated.
