linux-stable.git/arch/arm, branch v4.4.3 Linux kernel stable tree ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata 2016-02-25T20:01:20+00:00 Tony Lindgren tony@atomide.com 2016-01-14T20:20:48+00:00 a6e01f0c81d54678cdd50892462d12b672320e5e commit 4da597d16602d14405b71a18d45e1c59f28f0fd2 upstream. We don't want to write to .text so let's move ppa_zero_params and ppa_por_params to .data and access them via pointers. Note that I have not been able to test as we I don't have a HS omap4 to test with. The code has been changed in similar way as for omap3 though.

commit 4da597d16602d14405b71a18d45e1c59f28f0fd2 upstream.

We don't want to write to .text so let's move ppa_zero_params and
ppa_por_params to .data and access them via pointers.

Note that I have not been able to test as we I don't have a HS
omap4 to test with. The code has been changed in similar way as
for omap3 though.
