so incorrectly by ANDing the fecn mask. The fecn bit is bit 31. Bool is
not a native data type and is up to the compiler to implement how it

The driver progress routines can call cond_resched() when
a timeslice is exhausted and irqs are enabled.
If the ULP had been holding a spin lock without disabling irqs and
the post send directly called the progress routine, the cond_resched()
could yield allowing another thread from the same ULP to deadlock
on that same lock.
Correct by replacing the current hfi1_do_send() calldown with a unique
one for post send and adding an argument to hfi1_do_send() to indicate
that the send engine is running in a thread. If the routine is not
running in a thread, avoid calling cond_resched().

Sparse tool complains about undeclared symbols in usnic_ib_verbs.c
and usnic_ib_sysfs.c This is caused by lack of direct include of
appropriate usnic_ib_verbs.h and usnic_ib_sysfs.h, where all
these functions were declared.
Simple include eliminates 30 warnings similar to the below one:
drivers/infiniband/hw/usnic/usnic_ib_sysfs.c:304:6: warning: symbol
'usnic_ib_sysfs_unregister_usdev' was
not declared. Should it be static?

Function alloc_skb() will return a NULL pointer when there is no enough
memory. However, the return value of alloc_skb() is directly used
without validation in function send_fw_pass_open_req(). This patches
checks the return value of alloc_skb() against NULL.

After checking the path upwards towards root complex, actualy check
root complex atomic_req capability, and not our own NIC.
Verify that the PCIe device control register's atomic egress block
is cleared in the path.
Verify that the PCIe version is at least 2.
