So now we do not flush cache for any memory region. Shouldn't we still flush
at least kernel and purgatory segments.
kexec-tools loads a new kernel and purgatory executable. Some of those bits
might still be only in D-cache and we disable D-cache before control is passed
to the purgatory binary. Purgatory and some initial part of kernel code is
executed with D-cache disabled. So, We might land into a situation where correct
code is not executed while D-cache is disabled, no?
