Build Qualcomm QCM2290 interconnect driver as a kernel module by default.
QUPv3 GENI IP uses the interconnects and provides UARTs, but since the
dependency is not yet displayed in the platform qcm2290.dtsi file, it
could be assumed that the interconnect IP is preconfigured, thus building
the driver as a module and placing it in an initramfs should be sufficient

current->bio_list will be set under submit_bio() context, in this case
bitmap io will be added to the list and wait for current io submission to

commit 874807a831 ("md/raid1{,0}: fix deadlock in bitmap_unplug.") fix
the deadlock by handling plugged bio by daemon thread.
On the one hand, the deadlock won't exist after commit a214b949d8
("blk-mq: only flush requests from the plug in blk_mq_submit_bio"). On
the other hand, current solution makes it impossible to flush plugged bio
in raid1/10_make_request(), because this will cause that all the writes

If bitmap is enabled, bitmap must update before submitting write io, this
is why unplug callback must move these io to 'conf->pending_io_list' if
'current->bio_list' is not empty, which will suffer performance
degradation.
A new helper md_bitmap_unplug_async() is introduced to submit bitmap io

Commit 6cce3b23f6 ("[PATCH] md: write intent bitmap support for raid10")
add bitmap support, and it changed that write io is submitted through
daemon thread because bitmap need to be updated before write io. And
later, plug is used to fix performance regression because all the write io
will go to demon thread, which means io can't be issued concurrently.
However, if bitmap is not enabled, the write io should not go to daemon
thread in the first place, and plug is not needed as well.

Note that unlimited plugged bio still need to be optimized, for example,
in the case of lots of dirty pages writeback, this will take lots of

rdev and replacement are read as NULL in raid10_write_request(). This
