From: Palmer Dabbelt <palmer@xxxxxxxxxxxx>
[ Upstream commit e7681beba992d5a196476d5d79dfcb48f2a2c477 ]
This was broken by the original refactoring (as the XIP definitions
depend on <asm/pgtable.h>) and then more broken by the merge (as I
accidentally took the old version). This fixes both breakages, while
also pulling this out of <asm/asm.h> to avoid polluting most assembly
files with the XIP fixups.
Fixes: bee7fbc38579 ("RISC-V CPU Idle Support")
Fixes: 63b13e64a829 ("RISC-V: Add arch functions for non-retentive suspend entry/exit")
