treewide: replace '---help---' in Kconfig files with 'help'
kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables
samples: binderfs: really compile this sample and fix build issues
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

The MFW may make a call to qed and then to qedf for protocol statistics
while the function is still probing. If this happens it's possible that
some members of the struct qedf_ctx may not be fully initialized which can
result in a NULL pointer dereference or general protection fault.
To prevent this, add a new flag call QEDF_PROBING and set it when the
__qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data()
function we can check if the function is still probing and return
immediantely before any uninitialized structures can be touched.

If a port is brought down for an extended period of time, the fipvlan
counter gets exhausted and the driver will fall back to default VLAN 1002
and call fcoe_ctlr_link_up to log in. However, the switch will discard the
FLOGI attempt because the VLAN is now different.
Keep track of the number of FLOGI attempts and if a threshold of
QEDF_FLOGI_RETRY_CNT is exceeded, perform a context soft reset.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
The original code used a for-loop that looped over each of the 8 bytes
and copied them into a temporary buffer. pci_get_dsn() uses two calls to
pci_read_config_dword, and correctly bitwise ORs them into a u64. Thus,
we can simplify the snprintf significantly using %016llX on a u64 value.

Pull SCSI updates from James Bottomley:
"This is mostly update of the usual drivers: qla2xxx, ufs, smartpqi,
lpfc, hisi_sas, qedf, mpt3sas; plus a whole load of minor updates. The
only core change this time around is the addition of request batching
for virtio. Since batching requires an additional flag to use, it
should be invisible to the rest of the drivers"

There is a race b/w fipvlan request and response path:
=====
qedf_fcoe_process_vlan_resp:113]:2: VLAN response, vid=0xffd.
qedf_initiate_fipvlan_req:165]:2: vlan = 0x6ffd already set.
qedf_set_vlan_id:139]:2: Setting vlan_id=0ffd prio=3.
======
The request thread sees that vlan is already set and fails to call
ctrl_link_up.
Fix:
- While setting vlan_id use local variable and before setting vlan_id.
- Call fcoe_ctlr_link_up in next iteration of fipvlan request.

Problem Statement:
- Driver has fc_id of 0xcc0200
- Driver gets link down (due to test) and calls fcoe_ctlr_link_down().
- At this point, the fc_id of the initiator port is zeroed out.
- Driver gets a link up 14 seconds later.
- Driver performs FIP VLAN request, gets a response from the switch.
- No change in VLAN is detected.
- Driver then notifies libfcoe via fcoe_ctlr_link_up().
- Libfcoe then issues a multicast discovery solicitation as expected.
- Cisco FCF responds to that correctly.
- Libfcoe at this point starts a 3 sec count-down to allow any other FCFs
to be discovered. However, at this point, it has been 20 seconds since
the last FKA from the driver (which would have been sent prior to
backlink toggle), which causes the CVL to be issued from Cisco CVL from
the switch is dropped by the driver as the vx_port identification
descriptor is present and has value of 0xcc0200, which does not match
the driver's value of 0. Libfcoe completes the 3 sec count down and
proceeds to issue FLOGI as per protocol. Switch rejects FLogi request.
All subsequent FLOGI requests from libfc are rejected by the switch
(possibly because it is now expecting a new solicitation). This
situation will continue until the next link toggle.
Solution:
The Vx_port descriptor in the CVL has three fields:
MAC address
Fabric ID
Port Name
Today, the code checks for both #1 and #2 above. In the case where we went
through a link down, both these will be zero until FLOGI succeeds.
We should change our code to check if any one of these 3 is valid and if
so, handle the CVL (basically switching from AND to OR). The port name
field is definitely expected to be valid always.
