sys/arch/amd64/include: codepatch.h
sys/arch/amd64/amd64: locore.S copy.S
Log message:
Add CODEPATCH_CODE() macro to simplify defining a symbol for a chunk
of code to use in codepatching. Use that for all the existing
codepatching snippets.
Similarly, add CODEPATCH_CODE_LEN() which is CODEPATCH_CODE() but also
provides a short variable holding the length of the codepatch snippet.
Use that for some snippets that will be used for retpoline replacement.
