linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

From: Rusty Russell <redacted> In ELFv2, r12 is supposed to equal to PC on entry to a function. Our stubs use r11, so change swap that with r12. Signed-off-by: Rusty Russell <redacted> --- arch/powerpc/kernel/module_64.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-)
