Also, we want to check against nr_cpu_ids, not num_possible_cpus().
The latter works, but the correct bounds check is < nr_cpu_ids.

xsave_cntxt_init() does something like:
cpuid(0xd, ..); // find out what features FP/SSE/.. etc are supported
xsetbv(); // enable the features known to OS
cpuid(0xd, ..); // find out the size of the context for features enabled
Depending on what features get enabled in xsetbv(), value of the
cpuid.eax=0xd.ecx=0.ebx changes correspondingly (representing the
size of the context that is enabled).
As we don't have volatile keyword for native_cpuid(), gcc 4.1.2
optimizes away the second cpuid and the kernel continues to use
the cpuid information obtained before xsetbv(), ultimately leading to kernel
crash on processors supporting more state than the legacy FP/SSE.
Add "volatile" for native_cpuid().

Randy Dunlap reported the following build error:
"When CONFIG_SMP=n, CONFIG_X86_MSR=m:
ERROR: "msrs_free" [drivers/edac/amd64_edac_mod.ko] undefined!
ERROR: "msrs_alloc" [drivers/edac/amd64_edac_mod.ko] undefined!"
This is due to the fact that <arch/x86/lib/msr.c> is conditioned on
CONFIG_SMP and in the UP case we have only the stubs in the header.
Fork off SMP functionality into a new file (msr-smp.c) and build
msrs_{alloc,free} unconditionally.

The reiserfs lock -> inode mutex dependency gets inverted when we
relax the lock while walking to the tree.
To fix this, use a specialized version of reiserfs_mutex_lock_safe
that takes care of mutex subclasses. Then we can grab the inode
mutex with I_MUTEX_XATTR subclass without any reiserfs lock
dependency.
This fixes the following report:

Instead of using the IS_I9XX etc macros that expand to a ton of
comparisons, use new struct intel_device_info to capture the
capabilities of the different chipsets. The drm_i915_private struct
will be initialized to point to the device info that correspond to
the actual device and this way, testing for a specific capability is
just a matter of checking a bit field.

Prior to this patch, if pci_read_config_byte(dev, PCI_CACHE_LINE_SIZE, ...)
returns 0 for all dev, pci_cache_line_size ends up set to zero
(instead of pci_dfl_cache_line_size).
This patch ensures the pci_cache_line_size = pci_dfl_cache_line_size
setting in the above scenario.
This happens in case of a kvm-88 guest (where, consequently, the rtl8139
NIC failed to initialize).

Having read the PM part of the PCIe 2.0 specification more carefully
I think that it was a mistake to restrict the wake-up enable
propagation to non-PCIe devices, because if we do not request
control of the root ports' PME registers via OSC, PCIe PME is
supposed to be handled by the platform, just like the non-PCIe PME.
Even if we do that, the wake-up propagation is done to allow the
devices to wake up the system from sleep states which involves the
platform anyway, so it won't hurt.

Commit 3d1e4631 ("get rid of init_file()") removed the export of
alloc_file() -- possibly inadvertently, since that commit mainly
consisted of deleting the lines between the end of alloc_file() and
the start of the code in init_file().
There is in fact one modular use of alloc_file() in the tree, in
drivers/infiniband/core/uverbs_main.c, so re-add the export to fix:
ERROR: "alloc_file" [drivers/infiniband/core/ib_uverbs.ko] undefined!

Dirk reports that nothing is displayed on LVDS when using ubuntu 9.1 after
close/reopen the LID. And I also reproduce this issue on another laptop.
After some tests and debug, it seems that it is related with that the
LVDS status is not updated in time in course of suspend/resume.
Now the LID state is used to check whether the LVDS is connected or
disconnected. And when the LID is closed, it means that the LVDS is
disconnected. When it is reopened, it means that the LVDS is connected.
At the same time on some distributions the LID event is also used to put
the system into suspend state. When the LID is closed, the system will enter
the suspend state. When the LID is reopened, the system will be resumed.
In such case when the LID is closed, user-space script will receive the LID
notification event and detect the LVDS as disconnected. Then the system will
enter the suspended state. When the LID is reopened, the system will be
resumed. As the LVDS status is not updated in course of resume, it will cause
that the LVDS connector is marked as unused and disabled. After the resume is
finished,user-space script will try to configure the display mode for LVDS.
But unfortunately as the LVDS status is not updated in time and it is still
marked as disconnected, the LVDS and its corresponding CRTC will be disabled
again in the function of drm_helper_disable_unused_functions after changing
mode for LVDS.
So we had better check and update the status of LVDS connector after receiving
the LID notication event. Then after the system is resumed from suspended
state, we can set the display mode for LVDS correctly.

The MALATA PC-81005 laptop always reports that the LID status is closed and we
can't use it reliabily for LVDS detection. So add this box into the quirk list.

This is due the fact that uart_list list was populated in
omap_serial_early_init() and omap_uart_enable_irqs() went through this
list even when serial idle wasn't enabled for all uarts.
This patch moves the code that populates the uart_list and enables uart
clocks into omap_serial_init_port().

The I/O area of the SMSC LPC47M1xx chips which we use, gives access to
a lot of registers, some of which are related to fan speed monitoring
and control, but many are not. At the moment, the smsc47m1 driver
requests the whole I/O port range. This could easily result in
resource conflicts with either ACPI or other drivers.
Request only the I/O ports we really use, to prevent such conflicts.

As predicted during code review, the sysctl(2) changes made systems with
old glibc nearly unusable. About every command gives a:
warning: process `ls' used the deprecated sysctl system call with 1.4
warning in the log.
I see this on a SUSE 10.0 system with glibc 2.3.5.
Don't warn for this common case.
