I noticed that hotplug of one setup does not work with recent change in
pci tree.After checking the bridge conf setup, I noticed that the bridges get
assigned but do not get enabled.The reason is the following commit, while simply ignores bridge
resources when enabling a pci device:| commit bbef98ab0f019f1b0c25c1acdf1683c68933d41b

| PCI: defer enablement of SRIOV BARS
|...
| NOTE: Note, there is subtle change in the pci_enable_device() API. Any
| driver that depends on SRIOV BARS to be enabled in pci_enable_device()
| can fail.Put back bridge resource and ROM resource checking to fix the problem.
That should fix regression like BIOS does not assign correct resource to
bridge.Discussion can be found at:

Before registering an adapter to i2c subsystem, we need make sure
driver is ready for incoming i2c xfer, becasue the i2c_add_adapter()
may trigger a i2c device driver's proble function which may start
some real i2c xfer. I met this issue when integrating a TSC2007 i2c
touch screen device with the i2c-eg20t driver.This patch will call request_irq() and hw init before calling
i2c_add_adapter().Signed-off-by: Feng Tang

Currently the fifo depth is set to zero for OMAP4 which disables

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined
in the platform data of the i2c device. When DT is not enabled,
the above function always returns -EINVAL. Since there can be
some i2c devices which don't need to configure any gpio lines,
the probe of such devices would fail here. Changing the default
return value to success would fix this issue.Signed-off-by: Tushar Behera

This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1.
It blows up the i915 seqno tracking, resulting in the
BUG_ON(seqno == 0);
in i915_wait_request() triggering, which will cause lock-ups.

This adds a default setting for semaphores parameter, and enables

SNB, we do not enable them by default. But they can still be enabled

This prevents an in-kernel division by zero which happens when we are
asking for i915_chipset_val too quickly, or within a race condition
between the power monitoring thread and userspace accesses via debugfs.The issue can be reproduced easily via the following command:
while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; doneThis is particularly dangerous because it can be triggered by
a non-privileged user by just reading the debugfs entry.This issue was also found independently by Konstantin Belousov

commit 4dcfe1025b513c2c1da5bf5586adb0e80148f612
Author: Peter Zijlstra
Date: Thu Nov 10 13:01:10 2011 +0100sched: Avoid SMT siblings in select_idle_sibling() if possible
stopped selecting an idle SMT sibling when there are no idle
cores in a single socket system.Intent of the select_idle_sibling() was to fallback to an idle
SMT sibling, if it fails to identify an idle core. But this
fallback was not happening on systems where all the scheduler
domains had `SD_SHARE_PKG_RESOURCES' flag set.Fix it. Slightly bigger patch of cleaning all these goto's etc
is queued up for the next release.Reported-by: Mike Galbraith
