x86, paravirt_ops: use unsigned long instead of u32 for alloc_p*() pfn args
This patch changes the pfn args from 'u32' to 'unsigned long' on alloc_p*() functions on paravirt_ops, and the corresponding implementations for Xen and VMI. The prototypes for CONFIG_PARAVIRT=n are already using unsigned long, so paravirt.h now matches the prototypes on asm-x86/pgalloc.h. It shouldn't result in any changes on generated code on 32-bit, with or without CONFIG_PARAVIRT. On both cases, 'codiff -f' didn't show any change after applying this patch. On 64-bit, there are (expected) binary changes only when CONFIG_PARAVIRT is enabled, as the patch is really supposed to change the size of the pfn args.
