ACPI hotplug panic with current git head
http://lkml.org/lkml/2009/1/10/136
Rather than reverting the entire commit that causes the crash:
e8c331e963c58b83db24b7d0e39e8c07f687dbc6
"PCI hotplug: introduce functions for ACPI slot detection"
simply harden against it while the changes to
the hotplug code on this particularl machine are understood.

Although rfkill support for the EEE bluetooth device has been added to
2.6.28-rc the appropriate ACPI accessor definitions were not added, so
the support was non functional. The patch below adds the get and set
accessors and has been verified to work on an EEE 901.

Check CONFIG_FREEZER instead of CONFIG_PM because kprobe booster
depends on freeze_processes() and thaw_processes() when CONFIG_PREEMPT=y.
This fixes a linkage error which occurs when CONFIG_PREEMPT=y, CONFIG_PM=y
and CONFIG_FREEZER=n.

ACPI thermal driver only re-evaluate VALID trip points.
For the broken BIOS show in
http://bugzilla.kernel.org/show_bug.cgi?id=8544
the active[0] is set to invalid at boot time
and it will not be re-evaluated again.
We can still get a single warning message at boot time.

* git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable:
Btrfs: fix ioctl arg size (userland incompatible change!)
Btrfs: Clear the device->running_pending flag before bailing on congestion
|
|
The structure used to send device in btrfs ioctl calls was not
properly aligned, and so 32 bit ioctls would not work properly on
64 bit kernels.
We could fix this with compat ioctls, but we're just one byte away
and it doesn't make sense at this stage to carry about the compat ioctls
forever at this stage in the project.
This patch brings the ioctl arg up to an evenly aligned 4k.

Btrfs maintains a queue of async bio submissions so the checksumming
threads don't have to wait on get_request_wait. In order to avoid
extra wakeups, this code has a running_pending flag that is used
to tell new submissions they don't need to wake the thread.
When the threads notice congestion on a single device, they
may decide to requeue the job and move on to other devices. This
makes sure the running_pending flag is cleared before the
job is requeued.
It should help avoid IO stalls by making sure the task is woken up
when new submissions come in.

This reverts commit 98e6e286d7b01deb7453b717aa38ebb69d6cefc0, as Yinghai
Lu reports that it breaks kexec with at least the e1000 and e1000e
drivers. The reason is that the shutdown sequence puts the hardware
into D3 sleep, and the commit causes us to claim that it then is in D0
(running) state just because we don't understand the PM capabilities.
Which then later makes "pci_set_power_state()" not do anything, and the
device never wakes up properly and just returns 0xff to everything.

Cavium OCTEON processor support was recently merged, so now we have
this CF driver for your consideration.
Most OCTEON variants have *no* DMA or interrupt support on the CF
interface so for these, only PIO is supported. Although if DMA is
available, we do take advantage of it.

This is an initial patch to do support for objects which needs physical
contiguous main ram, cursors and overlay registers on older chipsets.
These objects are bound on cursor bin, like pinning, and we copy

notes:
possible over the top in attach/detach operations.
no overlay support yet.

When mode setting is first initialized, the driver will call into
drm_helper_initial_config() to set up an initial output and framebuffer
configuration. This routine is responsible for probing the available
connectors, encoders, and crtcs, looking for modes and putting together
something reasonable (where reasonable is defined as "allows kernel
messages to be visible on as many displays as possible").
However, the code was a bit too aggressive in setting default modes when
none were found on a given connector. Even if some connectors had modes,
any connectors found lacking modes would have the default 800x600 mode added
to their mode list, which in some cases could cause problems later down the
line. In my case, the LVDS was perfectly available, but the initial config
code added 800x600 modes to both of the detected but unavailable HDMI
connectors (which are on my non-existent docking station). This ended up
preventing later code from setting a mode on my LVDS, which is bad.
This patch fixes that behavior by making the initial config code walk
through the connectors first, counting the available modes, before it decides
to add any default modes to a possibly connected output. It also fixes the
logic in drm_target_preferred() that was causing zeroed out modes to be set
as the preferred mode for a given connector, even if no modes were available.

This patch removes the tty->low_latency setting.
For irq based hvc_console backends the tty->low_latency must be set to 0,
because the tty_flip_buffer_push() function must not be called from IRQ context
(see drivers/char/tty_buffer.c).
For polled backends, the low_latency setting causes the bug trace below, because
tty_flip_buffer_push() is called within an atomic context and subsequent calls
might sleep due to mutex_lock.

The PAPR says that the property for specifying the number of SLBs should
be called "slb-size". We currently only look for "ibm,slb-size" because
this is what firmware actually presents.
This patch makes us look for the "slb-size" property as well and in
preference to the "ibm,slb-size". This should future proof us if
firmware changes to match PAPR.
