Re: [PATCH v3] powerpc: Do not make the entire heap executable

Denys Vlasenko [off-list ref] writes:

On 32-bit powerps the ELF PLT sections of binaries (built with --bss-plt,
or with a toolchain which defaults to it) look like this:

...

 arch/powerpc/include/asm/page.h    | 10 +---------
 arch/powerpc/include/asm/page_32.h |  2 --
 arch/powerpc/include/asm/page_64.h |  4 ----
 fs/binfmt_elf.c                    | 34 ++++++++++++++++++++++++++--------
 include/linux/mm.h                 |  1 +
 mm/mmap.c                          | 20 +++++++++++++++-----

What tree is this against?

I can't get it to apply to either Linus' tree or linux-next.

cheers
