Reconfiguration notifier call for device node may fail by several reasons, but it always assumes kmalloc failures. This enables reconfiguration notifier call chain to get the actual error code rather than -ENOMEM by converting all reconfiguration notifier calls to return encapsulate error code with notifier_from_errno().

On MMUs such as FSL where we can guarantee the entire linear mapping is bolted, we don't need to worry about linear TLB misses. If on top of that we do a full table walk, we get rid of all recursive TLB faults, and can dispense with some state saving. This gains a few percent on TLB-miss-heavy workloads, and around 50% on a benchmark that had a high rate of virtual page table faults under the normal handler. While touching the EX_TLB layout, remove EX_TLB_MMUCR0, EX_TLB_SRR0, and EX_TLB_SRR1 as they're not used.

The Freescale hypervisor does not allow guests to write to the timebase registers (virtualizing the timebase register was deemed too complicated), so don't try to synchronize the timebase registers when we're running under the hypervisor.

The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

ePAPR hypervisors provide operating system services via a "hypercall" interface. The following steps need to be performed to make an hcall: 1. Load r11 with the hcall number 2. Load specific other registers with parameters 3. Issue instrucion "sc 1" 4. The return code is in r3 5. Other returned parameters are in other registers. To provide this service to the kernel, these steps are wrapped in inline assembly functions. Standard ePAPR hcalls are in epapr_hcalls.h, and Freescale extensions are in fsl_hcalls.h.

We expect this is actually faster, and we end up needing more space than we can get from the SPRGs in some instances. This is also useful when running as a guest OS - SPRGs4-7 do not have guest versions. 8 slots are allocated in thread_info for this even though we only actually use 4 of them - this allows space for future code to have more scratch space (and we know we'll need it for things like hugetlb).
