I got carried away and fixed all remaining -Wwrite-strings issues I could
reproduce in local builds.

Pipeline in Gitlab:

Andrew Cooper (6):
  x86/setup: Make the loader variable const
  x86/setup: Rework cmdline_cook() to be compatible with -Wwrite-strings
  xen/efi: Make efi-boot.h compile with -Wwrite-strings
  arm/duart: make dt_uart_init() compile with -Wwrite-strings
  arm/platforms: Make compatbile with -Wwrite-strings
  xen: Enable -Wwrite-strings

Randconfig found:

which looks to be the ACPI support.

should fix it, and it probably wants to merge into patch 5.
