Anup Patel	a14e7ee82c	lib: Redirect WFI trapped from VS/VU mode to HS-mode ... The WFI will trap as illegal instruction trap when executed in VS/VU mode so we just forward/redirect it to HS-mode so that hypervisor can deal with it appropriately.

Anup Patel	a88e424f6c	lib: Handle traps when doing unpriv load/store in get_insn() ... We can get a page/access trap when doing unpriv load/store in get_insn() function because on a SMP system Linux swapper running on HART A can unmap pages from page table used by HART B. To tackle this we extend get_insn() implementation so that if we get trap in get_insn() then we redirect it to S-mode as fetch page/access fault.
