Hi,
Here are the series of patches to fix kprobes not
to optimize on the functions in irqentry text ([4/4]).
To check the irqentry text always, [3/4] makes irqentry
text section unconditional.
This involves some other cleanups on h8300, xtensa,
because those sources declare section start/end symbol
as single characters, but generic sections.h declares
it as character arrays. So it leads build errors if
we apply [3/4].
Thank you,
