For experience with ARM cpus, I think this is only true for userspace.
Many CPUs only require explicit flushes when the icache is enabled. It's not
uncommon for bootloaders to leave the icache disabl

Not entirely true. There are cacheless MIPS CPUs (the m4k), and also

Hi,
RISC CPUs don't support self-modifying code unless the affected area
is flushed explicitly. This patch disables the extra effort for SMC.
The changes in this version would affect all CPUs except x86, but I'd
like to see if there are problems with some target, so that the
committed change can b
