Introduce a new svs_page_add function, which can be used to map in the user
space a VA from the kernel space. Use it to replace the PDIR_SLOT_PCPU slot: at boot time each CPU creates its own slot which maps only its own pcpu_entry plus the common area (IDT+ LDT). This way, the pcpu areas of the remote CPUs are not mapped in userland.
