2021-06-11arm64: insn: decouple patching from insn codeMark Rutland1-2/+0
Currently, <asm/insn.h> includes <asm/patching.h>. We intend that <asm/insn.h> will be usable from userspace, so it doesn't make sense to include headers for kernel-only features such as the patching routines, and we'd intended to restrict <asm/insn.h> to instruction encoding details. Let's decouple the patching code from <asm/insn.h>, and explicitly include <asm/patching.h> where it is needed. Since <asm/patching.h> isn't included from assembly, we can drop the __ASSEMBLY__ guards. At the same time, sort the kprobes includes so that it's easier to see what is and isn't incldued.

2021-05-27arm64: Move patching utilities out of instruction encoding/decodingJulien Thierry1-0/+15
Files insn.[c|h] containt some functions used for instruction patching. In order to reuse the instruction encoder/decoder, move the patching utilities to their own file.
