I am working on a ppc440gx platform and came across ppc44x_idle()
function. the actual requirement is to enable WAIT_STATE Enable bit
(MSR_WE) and External Interrupt enable bit (MSR_EE) on MSR. But for
ppc440, i see that MSR_DE bit (Debug Interrupt Enable) is also
enabled.
Any idea why MSR_DE enab
Right now there is no way to disable TEXT randomization on a PPC32
machine. text randomization happens even in the case of "echo 0 >
/proc/sys/kernel/randomize_va_space"
This happens due to the incorrect definition of ELF_ET_DYN_BASE at
arch/powerpc/include/asm/elf.h

ping !
any update on this ? As i understand, only powerpc and s390 uses the
randomize_et_dyn call; for all other architecture this is an obsolete
function call.
this call for another patch where randomize_et_dyn is removed.

The function randomize_et_dyn is redundant and is removed.
