riscv: Fix set_direct_map_default_noflush() to reset _PAGE_EXEC
[ Upstream commit b8b2711336f03ece539de61479d6ffc44fb603d3 ]
When resetting the linear mapping permissions, we must make sure that we
clear the X bit so that do not end up with WX mappings (since we set
PAGE_KERNEL).
Fixes: 395a21ff859c ("riscv: add ARCH_HAS_SET_DIRECT_MAP support")
