In the current implementation, final zone-mgmt request is issued with
submit_bio_wait() which marks the bio REQ_SYNC. This is needed since
immediate action is expected for zone-mgmt requests as these are
blocking operations. This also bypasses the scheduler in the
blk_mq_make_request() and dispatches the request directly into the
hw ctx.

This patch marks all the chained bios REQ_SYNC so that we can have
above-mentioned behavior for non-final bios also.

Currently t10-pi can only be built into the block layer which via
crc-t10dif pulls in a whole chunk of the Crypto API.  In fact all
users of t10-pi work as modules and there is no reason for it to
always be built-in.

This patch adds a new hidden option for t10-pi that is selected
automatically based on BLK_DEV_INTEGRITY and whether the users
of t10-pi are built-in or not.

Instead of using list_del_init() in a loop, that generates a lot of
unnecessary memory read/writes, iterate from the first request of a
batch and cut out a sublist with list_cut_before().

Apart from removing the list node initialisation part, this is more
register-friendly, and the assembly uses the stack less intensively.

list_empty() at the beginning is done with hope, that the compiler can
optimise out the same check in the following list_splice_init().

The comment says "this should never fail", but it definitely can fail
when you have odd initial boot filesystems, or kernel configurations.

So get the error handling right: filp_open() returns an error pointer.

commit 781fa0a9 ("ARM: bcm: Add support for BCM2711 SoC")

breaks boot of many other platforms (e.g. OMAP or i.MX6) if
CONFIG_ARCH_BCM2835 is enabled in addition to some multiplatform
config (e.g. omap2plus_defconfig). The symptom is that the OMAP
based board does not show any activity beyond "Starting Kernel ..."
even with earlycon.

Reverting the mentioned commit makes it work again.

The real fix is to add the missing NULL sentinel to the

Pull rdma fixes from Doug Ledford:
 "A small collection of -rc fixes. Mostly. One API addition, but that's
  because we wanted to use it in a fix. There's also a bug fix that is
  going to render the 5.5 kernel's soft-RoCE driver incompatible with
  all soft-RoCE versions prior, but it's required to actually implement
  the protocol according to the RoCE spec and required in order for the
  soft-RoCE driver to be able to successfully work with actual RoCE
  hardware.

  Summary:

   - Update Steve Wise info

   - Fix for soft-RoCE crc calculations (will break back compatibility,
     but only with the soft-RoCE driver, which has had this bug since it
     was introduced and it is an on-the-wire bug, but will make
     soft-RoCE fully compatible with real RoCE hardware)

   - cma init fixup

   - counters oops fix

   - fix for mlx4 init/teardown sequence

   - fix for mkx5 steering rules

   - introduce a cleanup API, which isn't a fix, but we want to use it
     in the next fix

   - fix for mlx5 memory management that uses API in previous patch"
