Newer Xen versions (at least 4.2) use per_cpu__init_tss instead of init_tss array. Take into account that.

This patch removes the __init modifier from an extern function declaration in acpi.h. Besides not being strictly needed, it requires the inclusion of linux/init.h, which is usually not even included directly, increasing header mess by a lot.

The 32-bit and 64-bit versions of copy_thread have functionally identical handling for copying the I/O bitmap, modulo differences in error handling. Clean up the error paths in both by moving the copy of the I/O bitmap to the end, to eliminate the need to free it if subsequent copy steps fail; move the resulting identical code to a static inline in a common header.
