If PAGE_SIZE is already defined in the system (e.g. in /usr/include/limits.h header) then gcc will trigger a redefinition error because of -Werror. This patch replaces usage of PAGE_* macros with XC_PAGE_* macros in order to avoid confusion between control domain page granularity (PAGE_* definitions) and guest domain page granularity. The exception is in osdep_xenforeignmemory_map() where we need the system page size to check whether the PFN array should be allocated with mmap() or with dynamic allocation.
