I'm cross compiling from 64 to 32 using:
make ARCH=x86
I've attached my config.
Hmm, if you can, could you tell me the output of kernel build with V=1?
I'd like to know whether posttest passed $(CONFIG_64BIT) or not.
Thank you,
Thanks.
Here is my result of 'make ARCH=x86' with your config-32 on x86-64.

TEST posttest

And also, I've tested test_get_len manually.
$ echo -e 'c0101038:\t2e a1 f8 b0 9e c0\t mov %cs:0xc09eb0f8,%eax' | arch/x86/tools/test_get_len
Succeed: decoded and checked 1 instructions
$ echo -e 'c0101038:\t2e a1 f8 b0 9e c0\t mov %cs:0xc09eb0f8,%eax' | arch/x86/tools/test_get_len y
Error: c0101038: 2e a1 f8 b0 9e c0 mov %cs:0xc09eb0f8,%eax
Error: objdump says 6 bytes, but insn_get_length() says 10 (attr:40000)
So, I assume that CONFIG_64BIT=y in your test environment. (I'm not sure why...)
Thank you,
