Since the misc device is registered only in the pci probe function
it has to be also unregistered in the counterpart pci remove function
and not in the module exit function.
In case of probe failure the driver was oopsing in module exit function.

If driver requests probe deferral,
it will be added to deferred_probe_pending_list
by driver_deferred_probe_add(), but, it used list_add().
Because of that, deferred probe will be run as reversed order.
This patch uses list_add_tail(), and solved this issue.

This patch (as1558) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers. Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.
After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state. Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.
The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep. Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.
A similar patch has already been applied as commit
151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during
suspend on ASUS computers). The patch supersedes that one and reverts
it. There are two differences:
The old patch added the flag at the USB level; this patch
adds it at the PCI level.
The old patch applied to all chipsets with the same vendor,
subsystem vendor, and product IDs; this patch makes an
exception for a known-good system (based on DMI information).

I noticed that the LBR fixups were not working anymore
on programs where they used to. I tracked this down to
a recent change to copy_from_user_nmi():
db0dc75d640 ("perf/x86: Check user address explicitly in copy_from_user_nmi()")
This commit added a call to __range_not_ok() to the
copy_from_user_nmi() routine. The problem is that the logic
of the test must be reversed. __range_not_ok() returns 0 if the
range is VALID. We want to return early from copy_from_user_nmi()
if the range is NOT valid.

The warning below triggers on AMD MCM packages because physical package
IDs on the cores of a _physical_ socket are the same. I.e., this field
says which CPUs belong to the same physical package.
However, the same two CPUs belong to two different internal, i.e.
"logical" nodes in the same physical socket which is reflected in the
CPU-to-node map on x86 with NUMA.
Which makes this check wrong on the above topologies so circumvent it.

In qlt_do_ctio_completion(), there's no point in calling
qlt_term_ctio_exchange() with a NULL cmd -- all that it does is crash
in a NULL pointer dereference, since it does
qlt_send_term_exchange(vha, cmd, &cmd->atio, 1);
and dereferencing &cmd->atio is a bad idea if cmd itself is NULL.
If we really need to do this, we could take the values from the
failed CTIO we're processing, but it's not clear if it's worth
the replumbing to do that.

When we create an explicit node ACL in tcm_qla2xxx_make_nodeacl(),
there is a call to tcm_qla2xxx_setup_nacl_from_rport(), which puts the
node ACL into the lport_fcport_map even though there is no session yet
for the initiator. Since the only time we remove entries from this
map is when we free a session, this means that if we later delete this
node ACL without the initiator ever creating a session, we'll leave
the nacl pointer in the btree pointing at freed memory.
This is especially bad if that initiator later does send us a command
that would cause us to create a dynamic ACL and session: we'll find
the stale freed nacl pointer in the btree and end up with use-after-free.
We could add more code to clear the btree entry when deleting the
explicit nacl, but the original insertion is pointless: without a
session attached, we'll just have to update the entry when a session
appears anyway. So we can just delete tcm_qla2xxx_setup_nacl_from_rport()
and the code that calls it.

The error paths in target_emulate_set_target_port_groups() are all
essentially "rc = -EINVAL; goto out;" but the code at "out:" ignores
rc and always returns success. This means that even if eg explicit
ALUA is turned off, the initiator will always see a good SCSI status
for SET TARGET PORT GROUPS.
Fix this by returning rc as is intended. It appears this bug was
added by the following patch:

This patch adds a new tcm_qla2xxx_clear_sess_lookup() call to clear session
specific s_id + loop_id entries used for se_node_acl pointer lookup ahead
of releasing se_session within the process context workqueue callback in
tcm_qla2xxx_free_session().
It makes the call in existing tcm_qla2xxx_clear_nacl_from_fcport_map()
code invoked from qlt_unreg_sess() in interrupt context w/ hardware_lock
held, ahead of the process context callback into qlt_free_session_done()
-> tcm_qla2xxx_free_session().
We are doing this to address a race between incoming ATIO or TMR packets
using stale se_node_acl pointer once session shutdown has been invoked via
qlt_unreg_sess() in qla_target.c LLD code, and when the entire tcm_qla2xxx
endpoint has not been forced into shutdown w/ echo 0 > ../$QLA2XXX_PORT/enable

byte-buffer to variable-length record buffer, causes systems using
EABI to crash very early in the boot cycle. The first entry in struct
log is a u64, which for EABI must be 8 byte aligned.
Make use of __alignof__() so the compiler to decide the alignment, but
allow it to be overridden using CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS,
for systems which can perform unaligned access and want to save
a few bytes of space.

We had a boot regression in Ux500 in the merge window because
two orthogonal pin control schemes for the PL011 were merged
at the same time:
- One using the .init() and .exit() hooks into the platform
for Ux500 putting the pins into default vs sleep state
respectively as the port was started/stopped.
commit a09806607fd20bed2f8c41fe22793386790a14aa
"ARM: ux500: switch to using pinctrl for uart0"
- One hogging the default setting at PL011 probe()
commit 258e055111d3cde2607e0d04eb91da2f7a59b591
"serial: amba-pl011: adopt pinctrl support"
To get a solution that works for both let's scrap the stuff
in the platform callbacks, instead have the driver itself
select default and sleep states when the port is
started/stopped. Hopefully this works for all clients.
Platform callbacks are bad for device tree migration anyway,
so this rids us of another problem in Ux500.
