Pull sched.h split-up from Ingo Molnar:
"The point of these changes is to significantly reduce the
<linux/sched.h> header footprint, to speed up the kernel build and to
have a cleaner header structure.
After these changes the new <linux/sched.h>'s typical preprocessed
size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K
lines), which is around 40% faster to build on typical configs.
Not much changed from the last version (-v2) posted three weeks ago: I
eliminated quirks, backmerged fixes plus I rebased it to an upstream
SHA1 from yesterday that includes most changes queued up in -next plus
all sched.h changes that were pending from Andrew.
I've re-tested the series both on x86 and on cross-arch defconfigs,
and did a bisectability test at a number of random points.
I tried to test as many build configurations as possible, but some
build breakage is probably still left - but it should be mostly
limited to architectures that have no cross-compiler binaries
available on kernel.org, and non-default configurations"

Chelsio T6 adapters reduce number of completion
to host by generating single completion for all
directly placed(DDP) iSCSI pdus in a sequence,
completion contains iSCSI hdr of the last pdu
in a sequence.
On receiving DDP completion cxgbit driver finds
iSCSI cmd using iscsit_find_cmd_from_itt_or_dump(),
then updates cmd->write_data_done, cmd->next_burst_len,
cmd->data_sn and calls __iscsit_check_dataout_hdr()
to validate iSCSI hdr.
(Update __iscsit_check_dataout_hdr parameter usage - nab)

Pull scsi target cleanups from Bart Van Assche:
"The changes here are:
- a few small bug fixes for the iSCSI and user space target drivers.
- minimize the target build time by about 30% by rearranging #include
directives
- fix the second argument passed to percpu_ida_alloc()
- reduce the number of false positive warnings reported by sparse
These patches pass Wu Fengguang's build bot tests and also the
linux-next tests"

Allocate resources dynamically for Upper layer driver's (ULD) like
cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx
queues which are allocated when ULD register with cxgb4 driver and freed
while un-registering. The Tx queues which are shared by ULD shall be
allocated by first registering driver and un-allocated by last
unregistering driver.

Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.
Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.
In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.

Instead of special casing the handful of callers that check for
iser-target rdma verbs specific shutdown, use a simple flag at
iscsit_transport->rdma_shutdown so each driver can signal this.
Also, update iscsi-target/tcp + cxgbit to rdma_shutdown = false.
