Bart Van Assche 55c40648d3 IB/hfi1: Suppress sparse warnings
Avoid that sparse reports the following warnings for the hfi1 driver:

trace.c:217:13: warning: no previous prototype for ‘print_u64_array’ [-Wmissing-prototypes]
user_sdma.c:1361:17: warning: dubious: !x & y

Bart Van Assche d55215c50e IB/hfi1: Use bit 0 instead of bit 1
The first argument of test_bit() and clear_bit() is a bit number and
not a bitmask. Hence change that first argument from (1 << 0) into 0.
This patch avoids that smatch reports the following warnings:

user_sdma.c:1059: sdma_cache_evict() warn: test_bit() takes a bit number
user_sdma.c:1590: sdma_rb_remove() warn: test_bit() takes a bit number

Leon Romanovsky f242d93ae9 IB/hfi1: Avoid large frame size warning
When CONFIG_FRAME_WARN is set to 1024 bytes, which is useful to find
stack consumers, we get a warning in hfi1 driver.

drivers/infiniband/hw/hfi1/affinity.c: In function
‘hfi1_get_proc_affinity’:
drivers/infiniband/hw/hfi1/affinity.c:415:1: warning: the frame size of
1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]

This change removes unneeded buf[1024] declaration and usage.

Jubin John f158486527 IB/hfi1: Fix pio map initialization
The pio map initialization function is off by 1 causing the last
kernel send context that is allocated to not get mapped into the
pio map which leads to the last kernel send context not being used
by any of the qps.

The send context reserved for VL15 is taken care of by setting the
scontext variable that is used as the index into the kernel send
context array to 1 and does not need to be accounted for in the
kernel send context counting loop as it is currently done.

Fix the kernel send context counting loop to account for all the
allocated send contexts and map all of them to the different VLs.

Dean Luick f6de3d39cf IB/hfi1: Correct 8051 link parameter settings
Two 8051 link settings, external device config and tuning method,
were written in the wrong location and the previous settings were
not cleared.  For both, clear the old value and write the new
value.

Sebastian Sanchez ce8b2fd095 IB/hfi1: Update pkey table properly after link down or FM start
When FM is disabled, and the HFI port on the switch is
changed from MgmtAllowed=YES to MgmtAllowed=NO and the
link is bounced, FULL_MGMT_P_KEY doesn't get cleared
from the pkey table. This also occurs when the QSFP
cable is moved from a switch port with MgmtAllowed=YES
to a MgmtAllowed=NO port. Clear pkey entry properly.

Also, when the driver is loaded and the switch port is
set to MgmtAllowed=NO, FULL_MGMT_P_KEY shouldn't be added
to pkey table after FM is started. Only set FULL_MGMT_P_KEY
in the pkey table if switch port is configured to
MgmtAllowed=YES.

Mike Marciniszyn 7049de65c9 IB/hfi1: Fix hard lockup due to not using save/restore spin lock
Commit b9b06cb6fe
("IB/hfi1: Fix missing lock/unlock in verbs drain callback")
added a spin lock.

Unfortunately, the new lock code can be called from a base
level interrupt state, and an interrupt that can get stacked
will attempt to get the same lock.

Fix by using the flag save/restore spin lock variation.

Dennis Dalessandro f48ad614c1 IB/hfi1: Move driver out of staging
The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
