MMIO emulation reads the last instruction executed by the guest and then emulates. If the guest is running in Little Endian order, or more generally in a different endian order of the host, the instruction needs to be byte-swapped before being emulated. This patch adds a helper routine which tests the endian order of the host and the guest in order to decide whether a byteswap is needed or not. It is then used to byteswap the last instruction of the guest in the endian order of the host before MMIO emulation is performed. Finally, kvmppc_handle_load() of kvmppc_handle_store() are modified to reverse the endianness of the MMIO if required.

On booke, "struct tlbe_ref" contains host tlb mapping information (pfn: for guest-pfn to pfn, flags: attribute associated with this mapping) for a guest tlb entry. So when a guest creates a TLB entry then "struct tlbe_ref" is set to point to valid "pfn" and set attributes in "flags" field of the above said structure. When a guest TLB entry is invalidated then flags field of corresponding "struct tlbe_ref" is updated to point that this is no more valid, also we selectively clear some other attribute bits, example: if E500_TLB_BITMAP was set then we clear E500_TLB_BITMAP, if E500_TLB_TLB0 is set then we clear this. Ideally we should clear complete "flags" as this entry is invalid and does not have anything to re-used. The other part of the problem is that when we use the same entry again then also we do not clear (started doing or-ing etc). So far it was working because the selectively clearing mentioned above actually clears "flags" what was set during TLB mapping. But the problem starts coming when we add more attributes to this then we need to selectively clear them and which is not needed.

Now that we have the vcpu floating-point and vector state stored in the same type of struct as the main kernel uses, we can load that state directly from the vcpu struct instead of having extra copies to/from the thread_struct. Similarly, when the guest state needs to be saved, we can have it saved it directly to the vcpu struct by setting the current->thread.fp_save_area and current->thread.vr_save_area pointers. That also means that we don't need to back up and restore userspace's FP/vector state. This all makes the code simpler and faster. Note that it's not necessary to save or modify current->thread.fpexc_mode, since nothing in KVM uses or is affected by its value. Nor is it necessary to touch used_vr or used_vsr.

The load_up_fpu and load_up_altivec functions were never intended to be called from C, and do things like modifying the MSR value in their callers' stack frames, which are assumed to be interrupt frames. In addition, on 32-bit Book S they require the MMU to be off. This makes KVM use the new load_fp_state() and load_vr_state() functions instead of load_up_fpu/altivec. This means we can remove the assembler glue in book3s_rmhandlers.S, and potentially fixes a bug on Book E, where load_up_fpu was called directly from C.

Using the address of 'empty_zero_page' as source address in order to clear a page is wrong. On some architectures empty_zero_page is only the pointer to the struct page of the empty_zero_page. Therefore the clear page operation would copy the contents of a couple of struct pages instead of clearing a page. For kvm only arm/arm64 are affected by this bug. To fix this use the ZERO_PAGE macro instead which will return the struct page address of the empty_zero_page on all architectures.

Using virt_to_phys on percpu mappings is horribly wrong as it may be backed by vmalloc. Introduce kvm_kaddr_to_phys which translates both types of valid kernel addresses to the corresponding physical address. At the same time resolves a typing issue where we were storing the physical address as a 32 bit unsigned long (on arm), truncating the physical address for addresses above the 4GB limit. This caused breakage on Keystone.

Pull Xen updates from Konrad Rzeszutek Wilk: "This has tons of fixes and two major features which are concentrated around the Xen SWIOTLB library. The short <blurb> is that the tracing facility (just one function) has been added to SWIOTLB to make it easier to track I/O progress. Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver "is used to translate physical to machine and machine to physical addresses of foreign[guest] pages for DMA operations" (Stefano) when booting under hardware without proper IOMMU. There are also bug-fixes, cleanups, compile warning fixes, etc. The commit times for some of the commits is a bit fresh - that is b/c we wanted to make sure we have the Ack's from the ARM folks - which with the string of back-to-back conferences took a bit of time. Rest assured - the code has been stewing in #linux-next for some time. Features: - SWIOTLB has tracing added when doing bounce buffer. - Xen ARM/ARM64 can use Xen-SWIOTLB. This work allows Linux to safely program real devices for DMA operations when running as a guest on Xen on ARM, without IOMMU support. [*1] - xen_raw_printk works with PVHVM guests if needed. Bug-fixes: - Make memory ballooning work under HVM with large MMIO region. - Inform hypervisor of MCFG regions found in ACPI DSDT. - Remove deprecated IRQF_DISABLED. - Remove deprecated __cpuinit. [*1]: "On arm and arm64 all Xen guests, including dom0, run with second stage translation enabled. As a consequence when dom0 programs a device for a DMA operation is going to use (pseudo) physical addresses instead machine addresses. This work introduces two trees to track physical to machine and machine to physical mappings of foreign pages. Local pages are assumed mapped 1:1 (physical address == machine address). It enables the SWIOTLB-Xen driver on ARM and ARM64, so that Linux can translate physical addresses to machine addresses for dma operations when necessary.

ERROR: "__divdi3" [fs/hfsplus/hfsplus.ko] undefined! Introduced by commit 099e9245 ("hfsplus: implement attributes file's header node initialization code"). i_size_read() returns loff_t, which is long long, i.e. 64-bit. node_size is size_t, which is either 32-bit or 64-bit. Hence "i_size_read(attr_file) / node_size" is a 64-by-32 or 64-by-64 division, causing (some versions of) gcc to emit a call to __divdi3(). Fortunately node_size is actually 16-bit, as the sole caller of hfsplus_init_header_node() passes a u16. Hence change its type from size_t to u16, and use do_div() to perform a 64-by-32 division.

This patch enhances the type safety for the kfifo API. It is now safe to put const data into a non const FIFO and the API will now generate a compiler warning when reading from the fifo where the destination address is pointing to a const variable. As a side effect the kfifo_put() does now expect the value of an element instead a pointer to the element. This was suggested Russell King. It make the handling of the kfifo_put easier since there is no need to create a helper variable for getting the address of a pointer or to pass integers of different sizes. IMHO the API break is okay, since there are currently only six users of kfifo_put(). The code is also cleaner by kicking out the "if (0)" expressions.
