Did you read the comments in the commit message to understand why
.previous is dangerous?

The previous section is not .text, but:
#ifdef CONFIG_KPROBES
.section .kprobes.text,"ax",%progbits
#else
.text
#endif
Either change the preceding .data to .pushsection .data, and the following
.text to .popsection, or duplicate the above ifdef; .pushsection/.popsection
is _far_ safer than using .previous.
