As long as there is no other non-const variable marked __initdata in the

compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.

Ganesan Ramalingam 249e2a38fb MIPS: Netlogic: MSI enable fix for XLS
MSI interrupts do not work on XLS after commit a776c49
( "PCI: msi: Disable msi interrupts when we initialize a pci device" )
because the change disables MSI interrupts on the XLS PCIe bridges
during the PCI enumeration.

Fix this by enabling MSI interrupts on the bridge in the
arch_setup_msi_irq() function. A new function xls_get_pcie_link()
has been introduced to get the PCI device corresponding to the
top level PCIe bridge on which MSI has to be enabled.

Also, update get_irq_vector() to use the new xls_get_pcie_link()
function and PCI_SLOT() macro for determining the IRQ of PCI devices.

When moving to common clk framework, the imx6q clks rom and mmdc_ch1_axi
get different on/off states than old clk driver, which breaks suspend
function.  There might be a better way to manage these clocks, but let's
takes the old clk driver approach to fix the regression first.

Linus Torvalds 21f27291f5 Driver Core fixes for 3.5-rc5
Here is a number of printk() fixes, specifically a few reported by the
 crazy blog program that ships in SUSE releases (that's "boot log" and
 not "web log", it predates the general "blog" terminology by many
 years), and the restoration of the continuation line functionality
 reported by Stephen and others.  Yes, the changes seem a bit big this
 late in the cycle, but I've been beating on them for a while now, and
 Stephen has even optimized it a bit, so all looks good to me.
 
 The other change in here is a Documentation update for the stable kernel
 rules describing how some distro patches should be backported, to
 hopefully drive a bit more response from the distros to the stable
 kernel releases.

Stuart Hayes 5f16012610 acpi_pad: fix power_saving thread deadlock
The acpi_pad driver can get stuck in destroy_power_saving_task()
waiting for kthread_stop() to stop a power_saving thread.  The problem
is that the isolated_cpus_lock mutex is owned when
destroy_power_saving_task() calls kthread_stop(), which waits for a
power_saving thread to end, and the power_saving thread tries to
acquire the isolated_cpus_lock when it calls round_robin_cpu().  This
patch fixes the issue by making round_robin_cpu() use its own mutex.

(ACPI video: Harden video bus adding.)

Some platforms don't have _DOS control method, but the ACPI
backlight still works.
We should not invoke _DOS for these platforms.

Steven Rostedt d36208227d printk: Optimize if statement logic where newline exists
In reviewing Kay's fix up patch: "printk: Have printk() never buffer its
data", I found two if statements that could be combined and optimized.

Put together the two 'cont.len && cont.owner == current' if statements
into a single one, and check if we need to call cont_add(). This also
removes the unneeded double cont_flush() calls.
