Subject: [PATCH v4 0/4] objtool: Fix INSN_CONTEXT_SWITCH
Date: Tue, 8 Apr 2025 00:02:12 -0700 [thread overview]
Message-ID: <cover.1744095216.git.jpoimboe@kernel.org> (raw)
I decided to keep the "unsupported instruction in callable function"
warning, it's not hurting anything. As a result we now have
INSN_SYSCALL and INSN_SYSRET.
v4:
- split up patches
- don't get rid of "unsupported instruction in callable function" warning
- split INSN_CONTEXT_SWITCH -> INSN_SYSCALL / INSN_SYSRET
v3: https://lore.kernel.org/9b23e4413873bee38961e628b0c73f6d3a26d494.1743799705.git.jpoimboe@kernel.org
Josh Poimboeuf (4):
objtool: Fix INSN_CONTEXT_SWITCH handling in validate_unret()
objtool: Split INSN_CONTEXT_SWITCH into INSN_SYSCALL and INSN_SYSRET
objtool: Stop UNRET validation on UD2
objtool, xen: Fix INSN_SYSCALL / INSN_SYSRET semantics
