[PATCH 0/4] Remove dependency of check subcmd upon orc

From: Julien Thierry

Hi,

Matt Helsley's change[1] provided a base framework to opt-in/out
objtool subcommands at compile time. This makes it easier for
architectures to port objtool, one subcommand at a time.

Orc generation relies on the check operation implementation. However,
the way this is done causes the check implementation to depend on the
implementation of orc generation functions to call if orc generation is
requested. This means that in order to implement check subcmd, orc
subcmd also need to be implemented.

These patches aim at removing that dependency, having orc subcmd
being built on top of the check subcmd.

Cheers,

objtool: Move object file loading out of check
objtool: Move orc outside of check
objtool: orc: Skip setting orc_entry for non-text sections
objtool: orc_gen: Move orc_entry out of instruction structure
