Linux is in the process of converting their seconds representation to 64 bits, so in order to support it consistently we should follow suit (which at some point in quite a few years we'd have to do anyway). To represent this in struct shared_info we leverage a 32-bit hole in x86-64's and arm's variant of the structure; for x86-32 guests the only (reasonable) choice we have is to put the extension in struct arch_shared_info. A note on the conditional suppressing the xen_wc_sec_hi helper macro definition in the ix86 case for hypervisor and tools: Neither of the two actually need this, and its presence causes the tools to fail to build (due to the inclusion of both the x86-64 and x86-32 variants of the header). As a secondary change, x86's do_platform_op() gets a pointless initializer as well as a pointless assignment of that same variable dropped.
