This is happening because a builtin module can't use directly a symbol
found on a module. By enabling CONFIG_MEDIA_ATTACH, the configuration
becomes valid, as dvb_attach() macro loads the module if needed, making
the symbol available to the builtin module.
While this bug started to appear after the patches that use IS_DEFINED
macro (like changeset 7b34be71db533f3e0cf93d53cf62d036cdb5418a), this
bug is a way ancient than that.
The thing is that, before the IS_DEFINED() patches, the logic used to be:
&& defined(MODULE))
struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
u8 i2c_addr,
struct i2c_adapter *i2c);
static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
u8 i2c_addr,
struct i2c_adapter *i2c)
{
printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__);
return NULL;
}
The above code, with the .config file used, was evoluting to FALSE
(instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'),
and were adding the static inline code at saa7134-dvb, instead
of the external call. So, while it weren't producing any compilation
error, the code weren't working either.
So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just
enable it, if MODULES is defined.

Commit c011470 (irqchip: gic: Perform the gic_secondary_init() call via
CPU notifier) moves gic_secondary_init() that used to be called in
.smp_secondary_init hook into a notifier call. But it changes the
system behavior a little bit. Before the commit, gic_cpu_init()
is called not only when kernel brings up the secondary cores but also
when system resuming procedure hot-plugs the cores back to kernel.
While after the commit, the function will not be called in the latter
case, where the 'action' will not be CPU_STARTING but
CPU_STARTING_FROZEN. This behavior difference at least causes the
following suspend/resume regression on imx6q.

The $obj-m/$obj-y vars should be adding new modules to build, not
overriding it. So, it should never use
$obj-y := foo.o
instead, it should use:
$obj-y += foo.o
Failing to do that is very bad, as it will suppress needed modules.

Commit 7cd8407 (ACPI / PM: Do not execute _PS0 for devices without
_PSC during initialization) introduced a regression on some systems
with Intel Lynxpoint Low-Power Subsystem (LPSS) where some devices
need to be powered up during initialization, but their device objects
in the ACPI namespace have _PS0 and _PS3 only (without _PSC or power
resources).
To work around this problem, make the ACPI LPSS driver power up
devices it knows about by using a new helper function
acpi_device_fix_up_power() that does all of the necessary
sanity checks and calls acpi_dev_pm_explicit_set() to put the
device into D0.

Commit 781d737 (ACPI: Drop power resources driver) introduced a
bug in the power resources initialization error code path causing
a NULL pointer to be referenced in acpi_release_power_resource()
if there's an error triggering a jump to the 'err' label in
acpi_add_power_resource(). This happens because the list_node
field of struct acpi_power_resource has not been initialized yet
at this point and doing a list_del() on it is a bad idea.
To prevent this problem from occuring, initialize the list_node
field of struct acpi_power_resource upfront.

Since commit 3757b94 (ACPI / hotplug: Fix concurrency issues and
memory leaks) acpi_bus_scan() and acpi_bus_trim() must always be
called under acpi_scan_lock, but currently the following scenario
violating that requirement is possible:
write_undock()
handle_eject_request()
hotplug_dock_devices()
dock_remove_acpi_device()
acpi_bus_trim()
Fix that by making write_undock() acquire acpi_scan_lock before
calling handle_eject_request() as appropriate (begin_undock() is
under the lock too in analogy with acpi_dock_deferred_cb()).

acpi_get_override_irq() was added because there was a problem with
buggy BIOSes passing wrong IRQ() resource for the RTC IRQ. The
commit that added the workaround was 61fd47e0c8476 (ACPI: fix two
IRQ8 issues in IOAPIC mode).
With ACPI 5 enumerated devices there are typically one or more
extended IRQ resources per device (and these IRQs can be shared).
However, the acpi_get_override_irq() workaround forces all IRQs in
range 0 - 15 (the legacy ISA IRQs) to be edge triggered, active high
as can be seen from the dmesg below:
ACPI: IRQ 6 override to edge, high
ACPI: IRQ 7 override to edge, high
ACPI: IRQ 7 override to edge, high
ACPI: IRQ 13 override to edge, high
Also /proc/interrupts for the I2C controllers (INT33C2 and INT33C3) shows
the same thing:
7: 4 0 0 0 IO-APIC-edge INT33C2:00, INT33C3:00
The _CSR method for INT33C2 (and INT33C3) device returns following
resource:
Interrupt (ResourceConsumer, Level, ActiveLow, Shared,,, )
{
0x00000007,
}
which states that this is supposed to be level triggered, active low,
shared IRQ instead.
Fix this by making sure that acpi_get_override_irq() gets only called
when we are dealing with legacy IRQ() or IRQNoFlags() descriptors.
While we are there, correct pr_warning() to print the right triggering
value.
This change turns out to be necessary to make DMA work correctly on
systems based on the Intel Lynxpoint PCH (Platform Controller Hub).

The ISP clock register content is not preserved over the ISP power domain
off/on cycle. Instead of setting the clock frequencies once at probe time
the clock rates set up is moved to the runtime_resume handler, which is
invoked after the related power domain is already enabled, ensuring the
clocks are properly configured when the device is actively used.
This fixes the FIMC-IS malfunctions and STREAM ON timeout errors accuring
on some boards:

Commit 699390354da6c258b65bf8fa79cfd5feaede50b6
('pty: Ignore slave pty close() if never successfully opened')
introduced a bug with ptys whereby a write() in parallel with an
open() on an existing pty could mistakenly indicate an I/O error.
Only indicate an I/O error if the condition on open() actually exists.

Suppose an initiator sends a DATA IN command with an allocation length
shorter than the FC transfer length -- we get a target message like
TARGET_CORE[qla2xxx]: Expected Transfer Length: 256 does not match SCSI CDB Length: 0 for SAM Opcode: 0x12
In that case, the target core adjusts the data_length and sets
se_cmd->residual_count for the underrun. But now suppose that command
fails and we end up in tcm_qla2xxx_queue_status() -- that function
unconditionally overwrites residual_count with the already adjusted
data_length, and the initiator will burp with a message like
qla2xxx [0000:00:06.0]-301d:0: Dropped frame(s) detected (0x100 of 0x100 bytes).
Fix this by adding on to the existing underflow residual count instead.

Here is a fun one. Bug seems to have been introduced by commit 140854cb,
almost two years ago. I have no idea why we only started seeing it now,
but we did.
Rough callgraph:
core_tpg_set_initiator_node_queue_depth()
`-> spin_lock_irqsave(&tpg->session_lock, flags);
`-> lio_tpg_shutdown_session()
`-> iscsit_stop_time2retain_timer()
`-> spin_unlock_bh(&se_tpg->session_lock);
`-> spin_lock_bh(&se_tpg->session_lock);
`-> spin_unlock_irqrestore(&tpg->session_lock, flags);
core_tpg_set_initiator_node_queue_depth() used to call spin_lock_bh(),
but 140854cb changed that to spin_lock_irqsave(). However,
lio_tpg_shutdown_session() still claims to be called with spin_lock_bh()
held, as does iscsit_stop_time2retain_timer():
* Called with spin_lock_bh(&struct se_portal_group->session_lock) held
Stale documentation is mostly annoying, but in this case the dropping
the lock with the _bh variant is plain wrong. It is also wrong to drop
locks two functions below the lock-holder, but I will ignore that bit
for now.
After some more locking and unlocking we eventually hit this backtrace:
------------[ cut here ]------------
