If a relocatable kernel is loaded at an address that is not 2MB aligned
and told not to relocate to zero, the kernel can crash due to
mark_rodata_ro() incorrectly changing some read-write data to read-only.
Scenarios where the misalignment can occur are when the kernel is
loaded by kdump or using
If a relocatable kernel is loaded at a non-zero address and told not to
relocate to zero (kdump or RELOCATABLE_TEST), the mapping of the
interrupt code at zero is left with RWX permissions.
That is a security weakness, and leads to a warning at boot if
CONFIG_DEBUG_WX is enabled:

Convert the raise/on parameter in ->dtr_rts() to bool through the
callchain. The parameter is used like bool. In USB serial, there
remains a few implicit bool -> larger type conversions because some
devices use u8 in their control messages.
In moxa_tiocmget(), dtr variable was reused for line

This patch tries to show usability of __xchg helper.
It is not intended to be merged, but I can convert
it to proper patchset if necessary.
There are many more places where __xchg can be used.
This demo shows the most spectacular cases IMHO:
- previous value is returned from function,
- temporary
