Merge tag 'v5.7-rc6' into objtool/core, to pick up fixes and resolve semantic conflict

Resolve structural conflict between:

  59566b0b622e: ("x86/ftrace: Have ftrace trampolines turn read-only at the end of system boot up")

which introduced a new reference to 'ftrace_epilogue', and:

  0298739b7983: ("x86,ftrace: Fix ftrace_regs_caller() unwind")

Which renamed it to 'ftrace_caller_end'. Rename the new usage site in the merge commit.
