Hi,
Here are the 9th version of the series to fix kprobes not
to optimize on the functions in irqentry text ([5/5]).
To check the irqentry text always, [4/5] makes irqentry
text section unconditional.
This involves some other cleanups on h8300, xtensa, and
cris ports, 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 [4/5].
Changes in v9
- Add cris cleanup patch (3/5).
BTW, in this series I just give a minimum fix for
arch dependent code, since this is a series to fix
a bug in x86 optprobe. However, IMHO, we should
revisit these "local _stext/_etext references" and
replace it with just including asm/sections.h.
And also, I would like to expose is_kernel_text()
as a generic routine for arch dependent code
so that they can use it.
Thank you,
