As of now, objtool only supports the x86_64 architecture but the
groundwork has already been done in order to add support for other
architectures without too much effort.
This series of patches adds support for the arm64 architecture
based on the Armv8.5 Architecture Reference Manual.
Objtool will be a valuable tool to progress and provide more guarentees
on live patching which is a work in progress for arm64.
Once we have the base of objtool working the next steps will be to
port Peter Z's uaccess validation for arm64.
Sorry about the long delay. I have some comments coming shortly.
One general comment: I noticed that several of the (mostly minor)
suggested changes I made for v1 haven't been fixed.
I'll try to suggest them again here for v4, so you don't need to go back
and find them. But in the future please try to incorporate all the
comments from previous patch sets before posting new versions. I'm sure
it wasn't intentional, as you did acknowledge and agree to most of the
changes. But it does waste people's time and goodwill if you neglect to
incorporate their suggestions. Thanks.
