On multi adapter setup if the uld registration fails even on
one adapter, the allocated resources for the uld on all the
adapters are freed, rendering the functioning adapters unusable.
This commit fixes the issue by freeing the allocated resources

With CONFIG_THERMAL=m, we get a build error:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type':
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal'
Once that is fixed by using IS_ENABLED() checks, we get a link error
against the thermal subsystem when cxgb4 is built-in:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init':
cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register'

cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister'
Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the
extra file into built-in.a, and we get another link failure against the
cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to
be adapted as well to work for both CONFIG_THERMAL=y and =m.

In cxgb_extension_ioctl(), the command of the ioctl is firstly copied from
the user-space buffer 'useraddr' to 'cmd' and checked through the
switch statement. If the command is not as expected, an error code
EOPNOTSUPP is returned. In the following execution, i.e., the cases of the
switch statement, the whole buffer of 'useraddr' is copied again to a
specific data structure, according to what kind of command is requested.
However, after the second copy, there is no re-check on the newly-copied
command. Given that the buffer 'useraddr' is in the user space, a malicious
user can race to change the command between the two copies. By doing so,
the attacker can supply malicious data to the kernel and cause undefined
behavior.
This patch adds a re-check in each case of the switch statement if there is
a second copy in that case, to re-check whether the command obtained in the
second copy is the same as the one in the first copy. If not, an error code
EINVAL is returned.

Unlike fs.val.lport and fs.val.fport, cxgb4_process_flow_match()
sets fs.val.{l,f}ip to net-endian values without conversion - they come
straight from flow_dissector_key_ipv4_addrs ->dst and ->src resp. So
the assignment in mk_act_open_req() ought to be a straight copy.

The BTF conflicts were simple overlapping changes.
The virtio_net conflict was an overlap of a fix of statistics counter,
happening alongisde a move over to a bonafide statistics structure
rather than counting value on the stack.

For FW_PORT_ACTION_GET_PORT_INFO32 messages, the
u.info32.lstatus32_to_cbllen32 is 32-bit Big Endian.
We need to translate that to CPU Endian in order to
test F_FW_PORT_CMD_DCBXDIS32.

t.qset_idx can be indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/net/ethernet/chelsio/cxgb3/cxgb3_main.c:2286 cxgb_extension_ioctl()
warn: potential spectre issue 'adapter->msix_info'
Fix this by sanitizing t.qset_idx before using it to index
adapter->msix_info
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].
