All the original Xen headers have xen_ulong_t as unsigned long type, however when they have been imported in Linux, xen_ulong_t has been replaced with unsigned long. That might work for x86 and ia64 but it does not for arm. Bring back xen_ulong_t and let each architecture define xen_ulong_t as they see fit. Also explicitly size pointers (__DEFINE_GUEST_HANDLE) to 64 bit. Changes in v3: - remove the incorrect changes to multicall_entry; - remove the change to apic_physbase.

Check for a node in the device tree compatible with "xen,xen", if it is present set xen_domain_type to XEN_HVM_DOMAIN and continue initialization. Map the real shared info page using XENMEM_add_to_physmap with XENMAPSPACE_shared_info. Changes in v4: - simpler parsing of Xen version in the compatible DT node. Changes in v3: - use the "xen,xen" notation rather than "arm,xen"; - add an additional check on the presence of the Xen version. Changes in v2: - replace pr_info with pr_debug.

Add a doc to describe the Xen ARM device tree bindings Changes in v5: - add a comment about the size of the grant table memory region; - add a comment about the required presence of a GIC node; - specify that the described properties are part of a top-level "hypervisor" node; - specify #address-cells and #size-cells for the example. Changes in v4: - "xen,xen" should be last as it is less specific; - update reg property using 2 address-cells and 2 size-cells.

sync_bitops functions are equivalent to the SMP implementation of the original functions, independently from CONFIG_SMP being defined. We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But under Xen you might be communicating with a completely external entity who might be on another CPU (e.g. two uniprocessor guests communicating via event channels and grant tables). So we need a variant of the bit ops which are SMP safe even on a UP kernel.

Use r12 to pass the hypercall number to the hypervisor. We need a register to pass the hypercall number because we might not know it at compile time and HVC only takes an immediate argument. Among the available registers r12 seems to be the best choice because it is defined as "intra-procedure call scratch register". Use the ISS to pass an hypervisor specific tag. Changes in v2: - define an HYPERCALL macro for 5 arguments hypercall wrappers, even if at the moment is unused; - use ldm instead of pop; - fix up comments.

Pull ubi fix from Artem Bityutskiy: "A single small fix for memory deallocation: we allocated memory using 'kmem_cache_alloc()' but were freeing it using 'kfree()' in some cases. Now we fix this by using 'kmem_cache_free()' instead." * tag 'upstream-3.6-rc5' of git://git.infradead.org/linux-ubi: UBI: fix a horrible memory deallocation bug

Commit 644595f8 ("compat: Handle COMPAT_USE_64BIT_TIME in net/socket.c") introduced a bug where the helper functions to take either a 64-bit or compat time[spec|val] got the arguments in the wrong order, passing the kernel stack pointer off as a user pointer (and vice versa). Because of the user address range check, that in turn then causes an EFAULT due to the user pointer range checking failing for the kernel address. Incorrectly resuling in a failed system call for 32-bit processes with a 64-bit kernel. On odder architectures like HP-PA (with separate user/kernel address spaces), it can be used read kernel memory.
