module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

Right now we forcibly clear ASPM state on all devices if the BIOS indicates
that the feature isn't supported. Based on the Microsoft presentation
"PCI Express In Depth for Windows Vista and Beyond", I'm starting to think
that this may be an error. The implication is that unless the platform
grants full control via _OSC, Windows will not touch any PCIe features -
including ASPM. In that case clearing ASPM state would be an error unless
the platform has granted us that control.This patch reworks the ASPM disabling code such that the actual clearing
of state is triggered by a successful handoff of PCIe control to the OS.
The general ASPM code undergoes some changes in order to ensure that the
ability to clear the bits isn't overridden by ASPM having already been
disabled. Further, this theoretically now allows for situations where
only a subset of PCIe roots hand over control, leaving the others in the
BIOS state.It's difficult to know for sure that this is the right thing to do -
there's zero public documentation on the interaction between all of these
components. But enough vendors enable ASPM on platforms and then set this
bit that it seems likely that they're expecting the OS to leave them alone.Measured to save around 5W on an idle Thinkpad X220.

This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem
and converts the devices to regular devices. The sysdev drivers are
implemented as subsystem interfaces now.After all sysdev classes are ported to regular driver core entities, the
sysdev implementation will be entirely removed from the kernel.Userspace relies on events and generic sysfs subsystem infrastructure
from sysdev devices, which are made available with this conversion.Cc: Haavard Skinnemoen

This allows a backend to filter on the dmesg reason as well as the pstore
reason. When ramoops is switched to pstore, this is needed since it has
no interest in storing non-crash dmesg details.Drop pstore_write() as it has no users, and handling the "reason" here

The buf_lock cannot be held while populating the inodes, so make the backend
pass forward an allocated and filled buffer instead. This solves the following
backtrace. The effect is that "buf" is only ever used to notify the backends
that something was written to it, and shouldn't be used in the read path.To replace the buf_lock during the read path, isolate the open/read/close
loop with a separate mutex to maintain serialized access to the backend.Note that is is up to the pstore backend to cope if the (*write)() path is
called in the middle of the read path.[ 59.691019] BUG: sleeping function called from invalid context at .../mm/slub.c:847

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.Reported-and-tested-by: Tomas M.

This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.Reference:

This is the first step towards global registration of cpuidle
states. The statistics used primarily by the governor are per-cpu
and have to be split from rest of the fields inside cpuidle_state,

is also per-cpu and moved.Signed-off-by: Deepthi Dharwar

Cpuidle governor only suggests the state to enter using the
governor->select() interface, but allows the low level driver to
override the recommended state. The actual entered state
may be different because of software or hardware demotion. Software
demotion is done by the back-end cpuidle driver and can be accounted
correctly. Current cpuidle code uses last_state field to capture the
actual state entered and based on that updates the statistics for the
state entered.Ideally the driver enter routine should update the counters,
and it should return the state actually entered rather than the time
spent there. The generic cpuidle code should simply handle where
the counters live in the sysfs namespace, not updating the counters.Reference:

Calling pm-suspend might trigger a recursive lock in it's code path.
In function acpi_hw_clear_acpi_status, acpi_os_acquire_lock holds
the lock acpi_gbl_hardware_lock before calling acpi_hw_register_write(),
then without releasing acpi_gbl_hardware_lock, this function calls
acpi_ev_walk_gpe_list, which tries to hold acpi_gbl_gpe_lock.
Both acpi_gbl_hardware_lock and acpi_gbl_gpe_lock are at same
lock-class and which might cause lock recursion deadlock.Following patch fixes this scenario by just releasing
acpi_gbl_hardware_lock before calling acpi_ev_walk_gpe_list.Changes since v0(https://lkml.org/lkml/2011/9/21/355):

These files were relying on module.h to come in via the path
in an include/acpi header file, but we don't want to have
instances of module.h being included from include/* files
if it can be avoided. Have the files include export.h instead.Signed-off-by: Paul Gortmaker
-
If a file is only exporting symbols and not using the core
modular infrastructure, it can get by with just including
the smaller export.h header, which is a lot smaller than the
module.h header.Signed-off-by: Paul Gortmaker
-
Files which aren't actually using infrastructure from module.h
shouldn't include it, as it is a big header with lots of child
includes spawned off.Signed-off-by: Paul Gortmaker
-
These files are using standard module API things like MODULE_AUTHOR
etc. and so should not be relying on an implicit presence of the
module.h header.Signed-off-by: Paul Gortmaker
