Module Name:    src

        src/sys/arch/x86/x86: cpu.c

Log Message:
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.
