7034228792 MIPS: Whitespace cleanup. 
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

8b5690f884 MIPS: irq: Remove IRQF_DISABLED 
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled and we even check
and yell when an interrupt handler returns with interrupts enabled (see
commit [b738a50a: genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

[ralf@linux-mips.org: Fixed up conflicts in
arch/mips/alchemy/common/dbdma.c, arch/mips/cavium-octeon/smp.c and
arch/mips/kernel/perf_event.c.]

The function _wrmsr() called by divil_lbar_disable()/enable() should be
called with the offset as the argument.

f18b2f67ea MIPS: Loongson: CS5536: Add missing RDMSRs for IDE and USB 
Add several missing RDMSRs for IDE and USB are missing to avoid the
agressive modification of the high 32 bits of the MSR.

Without this patch some usb devices may fail after printing "reset ehci
host ....." when reading the partition information.

916daba8a9 MIPS: Lemote 2F: Add cs5536 MFGPT timer support 
CPUFreq support for Loongson 2F requires an external timer.

Because the frequency of the MIPS Timer is related to the CPU frequency
which itself is variable another timer of constant frequency is required.

Export the mfgpt0 counter disable / enable operations for the coming
suspend support to suspend / resume the timer.

22c21003a9 MIPS: Lemote 2F: Add basic CS5536 VSM support 
Lemote Loongson 2F family machines use CS5536 as their south bridge and need
these lowlevel interfaces to access the devices on CS5536.

Virtualize the legacy devices on CS5536 as PCI devices.  This way users can
access the CS5536 PCI config space directly as a normal multi-function
PCI 2.2 device.
